This study aimed to assess the correlation between elevated serum cortisol levels and the occurrence of postoperative delirium subsequent to off-pump CABG. Methods: Conducted in the Department of Cardiac Surgery at BSMMU from October 2020 to September 2022, this comparative cross-sectional study included a total of 44 participants. Subjects, meeting specific criteria, were purposefully assigned to two groups based on off-pump CABG. Group A (n = 22) consisted of patients with normal serum cortisol levels, while Group B (n = 22) comprised individuals with high serum cortisol levels on the first postoperative day. Delirium onset was assessed at the bedside in the ICU on the 1st, 2nd, 3rd, 4th, and 5th postoperative days using standard tools, namely the Richmond Agitation Sedation score (RASS) and The Confusion Assessment Method (CAM-ICU). Data were collected based on the presence or absence of delirium. Statistical analysis utilized SPSS version 26.0, employing an independent Student’s t-test for continuous data and chi-square and Fischer’s exact test for categorical data. A p-value ≤ 0.05 was considered statistically significant. Results: Group-A had a mean age of 54.50 ± 17.97, and Group-B had a mean age of 55.22 ± 15.45, both with a male predominance (81.81% and 86.36% respectively). The mean serum cortisol level was significantly higher in Group B (829.71 ± vs. 389.98 ± 68.77). Postoperative delirium occurred in 27.3% of Group B patients, statistically significant compared to the 4.5% in Group A. However, patients in Group B who developed delirium experienced significantly longer postoperative ICU and hospital stays (79.29 ± 12.27 vs. 11.44 ± 2.85, p ≤ 0.05). There was one mortality in Group B, which was statistically not significant. Conclusion: This study observed a significant association between elevated serum cortisol levels in the postoperative period and the occurrence of postoperative delirium after off-pump coronary artery bypass grafting.展开更多

Low preoperative serum albumin is linked to poor outcomes, including acute kidney injury (AKI), after off-pump coronary artery bypass (OPCAB) surgery. This study aimed to assess the relationship between preoperative serum albumin levels and early postoperative renal injury. Methods: This prospective comparative cross-sectional study was conducted from August 2019 to February 2021 at the National Heart Foundation Hospital & Research Institute, Bangladesh. It included 160 adult patients with normal preoperative renal function undergoing OPCAB. Patients were divided into two groups: Group A (serum albumin ≥ 4.0 gm/dl) and Group B (serum albumin Results: Preoperative serum albumin was significantly different between groups (Group A: 4.21 ± 0.05 gm/dl, Group B: 3.69 ± 0.04 gm/dl, p = 0.028). Group B had a higher incidence of hypertension (71.25% vs. 51.25%, p st and 3rd postoperative days were higher in Group B (p th day. Postoperative AKI occurred in 18.75% of Group A and 36.25% of Group B. Multivariate regression indicated that low preoperative serum albumin is an independent risk factor for postoperative AKI (p = 0.012, OR = 1.815, CI: 0.675 - 1.162). Conclusion: Preoperative serum albumin level is a valuable predictor of postoperative renal function. Ensuring high normal serum albumin levels before surgery can help minimize the risk of postoperative AKI.展开更多

A 34-...Objectives We report a case in which a patient who suffered from angina secondary to mediastinal irradiation and have been treated by off-pump coronary artery bypass （OPCAB） in our hospital since 3 years ago. A 34-year-old man presented with angina for 8 years after receiving radiation therapy for Hodgkin＇s lymphoma. We retrospectively reviewed all the cases of OPCAB in our hospital and followed-up data for up to 3 years post-operatively. Mediastinal irradiation is probably the cause of significant ostial stenosis of left main coronary and right coronary artery. OPCAB grafting was performed on this patient 3 years ago. His angina disappeared after operation, and he recovered well during follow-up. Conclusions Patients with malignancies who have received mediastinal irradiation should be carefully followed up and routinely screened for the premature development of coronary artery disease. OPCAB may be an appropriate treatment for coronary artery disease caused by mediastinal irradiation.展开更多

Objectives: This study assessed short-term outcomes and functional improvements in LVD patients post-OPCAB. Methods: The study included 200 coronary artery disease patients who underwent isolated off-pump coronary artery bypass grafting (OPCAB) at the National Heart Foundation Hospital and Research Institute between January 2019 and June 2020. Patients were categorized into Group 1, with a left ventricular ejection fraction (LVEF) of 30% - 39%, and Group 2, with an LVEF of 40% or higher. Echocardiographic assessments of left ventricular dimensions and ejection fraction were performed preoperatively, at discharge, and one month postoperatively. Results: In Group 1, preoperative left ventricular internal dimensions during diastole (LVIDd) and systole (LVIDs) were 53.48 ± 4.40 mm and 44.23 ± 3.93 mm, respectively, with a left ventricular ejection fraction (LVEF) of 35.28% ± 2.26%. At discharge, these values improved to 51.58 ± 4.04 mm (LVIDd), 41.23 ± 5.30 mm (LVIDs), and 39.25% ± 3.75% (LVEF). One month postoperatively, further improvements were observed: 46.29 ± 3.76 mm (LVIDd), 37.45 ± 3.68 mm (LVIDs), and 43.22% ± 4.67% (LVEF). Group 2 showed similar positive outcomes, with preoperative values of 47.09 ± 5.06 mm (LVIDd), 35.11 ± 5.25 mm (LVIDs), and 50.13% ± 7.25% (LVEF), improving to 42.37 ± 4.18 mm (LVIDd), 31.05 ± 4.19 mm (LVIDs), and 55.33% ± 7.05% (LVEF) at one month postoperatively. Both groups demonstrated significant improvements in left ventricular function and NYHA class, with most patients moving from class III/IV to I/II. Complications were minimal, and no mortality was observed. Conclusion: OPCAB is safe and effective for patients with LVEF 30% - 39% and LVEF ≥ 40%, providing significant short-term functional improvements without increased risk.展开更多

Sixty patients who underwent standard OPCAB surgery were randomized into two groups. One group （30 patients） received mono-antiplatelet treatment （MAPT） with aspirin 100 mg daily and the other group received dual anfiplatelet treatment （DAPT） with aspirin 100 mg daily plus clopidogrel 75 mg daily. Platelet aggregations in response to arachi- donic acid （PLAA） and adenosine diphosphate （ADP） （PLADP） were measured preoperatively and on days 1 to 6, 8 and 10 after the antiplatelet agents were administered. A PLAA level above 20% was defined as aspirin resistance. Postoperative bleeding and other perioperative variables were also recorded. There were no significant differences between the two groups in baseline characteristics, average number of distal anastomosis, operation time, postoperative bleeding, ventilation time and postoperative hospital stay. However, the incidence of aspirin resistance was significantly lower in the DAPT group than that in the MAPT group on the first and second day after antiplatelet agents were given （62.1% vs, 32.1%, 34.5% vs. 10.7%, respectively, both P 〈 0.05）. There was no significant difference in postoperative complication between the two groups. DAPT with aspirin and clopidogrel can be safely applied to OPCAB patients early after the procedure. Moreover, clopidogrel reduces the incidence of OPCAB-related aspirin resistance.展开更多

Methods From January 2003 to August 2013, non-randomized 80 patients were treated with redo CABG in the Department of Cardiac Surgery, Peking University Third Hospital. Among these patients, 40 underwent on-pump CABG technique(redo-ONCAB group) and 40 underwent off-pump CABG technique(redo-OPCAB group). Furthermore, transmyocardial laser revascularization was performed in high-risk patients who were not suitable to conventional grafting. Clinical data of the two groups were recorded and analyzed including operation time, coronary grafts, incomplete revascularization, postoperative ventilation, perioperative stroke, and low output syndrome, etc. Results There were no significantly differences in age, gender distribution, incidences of hypertension, stroke, and other clinical characteristics between redo-OPCAB group and redo-ONCAB group(all P>0.05), except for incidences of renal dysfunction and pulmonary disease(all P<0.05). The number of grafting vessels in the redo-ONCAB and redo-OPCAB groups was 2.1 ± 0.74 and 1.4 ±0.52 respectively. There was significant difference between the two groups(P=0.0243). Compared with the redo-ONCAB group, there was shorter operation time(P=0.0045), postoperative ventilation(P=0.0211) and intensive care unit stay(P=0.0400), as well as fewer use of platelet(P=0.0338) and blood transfusion(P=0.0034) in the redo-OPCAB group. The incidence of incomplete revascularization(P=0.0253) and the use of transmyocardial laser revascularization(P=0.0052) were higher in the redo-OPCAB group than those in the redo-ONCAB group(all P<0.05). However, no significant differences were showed for the incidence of the use of intra aortic balloon pump and continuous renal replacement therapy, perioperative stroke, low output syndrome, and in-hospital mortality between the two groups(all P>0.05). Conclusion Redo CABG is the safety and efficacy surgical procedure, and redo-OPCAB technique with better outcomes is commended especially in high-risk patients.展开更多

In the ...The association between atrial fibrillation（AF） after coronary artery bypass grafting（CABG） and the surgical techniques selected has been extensively reported. However, no consistent results were obtained. In the present study, a meta-analysis was conducted by searching the electronic databases Pub Med, Embase, Web of Science, and Cochrane to identify the association of post-CABG AF with on-pump（conventional CABG, c CABG） or off-pump CABG（OPCABG）. Outcomes from randomized clinical trials（RCTs） and propensity score matching（PSM） trials were pooled by using the fixed-effect or the random-effect modeling method, and verified by the quality-effect modeling method. There were 35 studies with 36 independent reports that met the inclusion criteria and were eventually included in our meta-analysis. The total odds ratio（OR） of the incidence of post-CABG AF between OPCABG and c CABG was 0.80（95% CI 0.71–0.91）. The 25 randomized clinical trials（RCTs） had an OR of 0.69（95% CI 0.56–0.86）, while the OR of the 11 PSM trials was 0.88（95% CI 0.77–1.00）. Twenty-six studies involving the patients at a mean age no more than 65 years showed an OR of 0.76（95% CI 0.64–0.90）, whereas 10 studies with patients greater than 65 years old showed an OR of 0.90（95% CI 0.78–1.05）. The results of this meta-analysis suggest that OPCAB surgery may reduce the incidence of post-CABG AF when compared to c CABG and that younger patients may benefit more from OPCAB and have a lower incidence of post-CABG AF.展开更多

Pre-operative use of intra-aortic balloon pump has been shown to prevent this complication in high risk patients. The role of balloon pump in high risk patients has been questioned by our group. We modified the role of balloon pump in our patients, thus avoiding the conversion to cardiopulmonary bypass. Methods: 4063 off-pump coronary bypass surgeries were performed by a single surgeon in our center, over thirteen years. 130 intra-aortic balloons used between July 2002 and December 2015 were removed from the the-ater, once the distal anastomosis was performed. We studied this group of patients for—time and need for insertion, duration of balloon used, local insertion problems and survival. Results: Initially, we inserted intra-aortic balloons in high risk patients. We observed that, patients with low ejection fraction and patients with critical left main coronary artery disease were not the ones who actually needed balloon pump support. It was the patients who had ongoing ischemia, with preserved left ventricular function, and ST depression intra-operatively, who needed balloon pump support to perform complete anatomical revascularization. Conclusions: Intra-aortic balloon pump has helped us to position the heart without hemodynamic instability, thereby avoiding conversion to cardio-pulmonary bypass. This enabled us to perform off-pump surgery in virtually all areas of the heart, thus maintaining perfect hemodynamics.展开更多

Methods： Twenty-four patients with coronary artery disease were enrolled, twelve of which received OPCAB and the others underwent ONCAB. Left ventricular ejection fraction （LVEF）, E/A ratio at mitral orifice and Tel index were measured using transthoracic echocardiography before surgery and 3-7 days, 1 month, 3 months and 6 months after surgery. Results：Tel index of both groups decreased 3-7 days after surgery, with OPCAB group＇s lower than ONCAB group＇s. The difference between pre-and post-OPCAB was significant （P〈0.01）, but not for ONCAB group （P〈0.05）. Tel index of ONCAB decreased more significant than that of OPCAB 1 month after surgery, there was statistical difference between 3-7 days and 1 month after surgery in ONCAB （P〈0.01）. Afterwards, Tel index of the 2 groups decreased steadily with no significant difference between them at other time points. LVEF and E/A ratio decreased at first, then increased gradually, with no statistical differences between the 2 groups at all time points. Conclusion： The recovery of left ventricular function after OPCAB is earlier than ONCAB. Tel index is more sensitive than LVEF and E/A ratio in detecting cardiac function recoveries and can be considered as an accurate and simple method to evaluate left ventricular systolic and diastolic function.展开更多

Methods This study group included 70 consecutive patients scheduled for elective off-pump CABG. The patients with ejection fraction （EF） less than 0. 30, history of AF, use of class Ⅰ or Ⅲ antiarrhythmic drug, implanted pacemaker, postoperative myocardial infarction or chest reopening for pericardial tamponade were excluded. Preoperative and postoperative serum NT-proBNP levels were measured by radioimmunoassay technique. Results Postoperative AF occurred in 15 patients （21.4%）; these patients had significantly higher median NT-proBNP levels when compared with those without AF after the operation （ P 〈 0. 01 ）. Using multivariate logistic regression analyses, an increase in NT-proBNP level after CABG was found to be independently associated with AF （ OR = 3.78, 95% IC = 1.81 - 4. 89, P 〈 0. 01 ）. Increased age, diabetes mellitus, preoperative use of β-blocker, proximal right coronary artery involvement, and longer operation time were al- so associated with AF. Conclusions These results indicated that AF was associated with higher NT-proBNP concentrations after off pump CABG; the increase in NT-proBNP after CABG may play an important role in the occurrence of AF after the operation. The further studies are needed to define the reason that lead to higher NT-proBNP concentrations among the patients who present AF after off pump CABG.展开更多

Methods Between October 2002 to April 2003, twenty five cases underwent beating heart coronary artery revascularization without endotracheal general anesthesia, using high thoracic epidural anesthesia and analgesia. All the patients underwent epidural catheterization on the evening before the surgery. Resuits The patients in all received 71 grafts (single n = 11, double n = 5, triple n = 6, quadruple n = 3). Six patients underwent repeat coronary artery bypass. Except one was converted to general anesthesia and cardiopulmonary bypass, the other patients underwent off-pump coronary artery bypass graft surgery, 2 patients underwent grafting via left thoracotomy (MIDCAB) and the rest through mid sternotomy. There was no mortality. Mean length of stay in the intensive care unit was 16 .2 ( 4.2 hours and hospital was 3.0(1.2 days. Conclusions Our experience confirms the feasibility of performing multiple coronary artery bypasses in conscious patients without endotracheal general anesthesia展开更多

To combat this, miniaturized cardiopulmonary bypass circuits (MCPBC) have been created to lessen the inflammatory response to CPB. Here we examine early outcomes following coronary artery bypass grafting (CABG) using a MCPBC system compared to conventional bypass techniques at a single institution. Methods: 60 consecutive patients undergoing elective CABG were prospectively enrolled. Nine patients underwent coronary artery bypass grafting (CABG) with conventional CPB (cCABG), 33 underwent off-pump CABG (OPCAB), and the remaining 18 patients underwent CABG with a MCPBC system. Demographics and outcomes were compared between groups and statistical analyses applied. Results: No significant difference was observed in mortality between groups, with only one death reported in total. Morbidity was also low, totaling only 6.7%, with none occurring in the MCPBC group. The MCPBC group required less PRBC and total blood product transfusion than the cCABG and OPCABG groups (p = 0.05), but changes in PLT and Hct over time were not different between groups. Conclusions: The MCPBC system was shown to be comparable to conventional bypass and OPCABG in terms of postoperative complications and mortality. Furthermore, the MCPBC system had the advantage of a decreased transfusion requirement. Based on our preliminary observations, this mini-cardiopulmonary bypass circuit provides a safe alternative to conventional bypass techniques.展开更多

文摘Background: Following coronary artery bypass grafting (CABG), delirium emerges as a prevalent complication. This study aimed to assess the correlation between elevated serum cortisol levels and the occurrence of postoperative delirium subsequent to off-pump CABG. Methods: Conducted in the Department of Cardiac Surgery at BSMMU from October 2020 to September 2022, this comparative cross-sectional study included a total of 44 participants. Subjects, meeting specific criteria, were purposefully assigned to two groups based on off-pump CABG. Group A (n = 22) consisted of patients with normal serum cortisol levels, while Group B (n = 22) comprised individuals with high serum cortisol levels on the first postoperative day. Delirium onset was assessed at the bedside in the ICU on the 1st, 2nd, 3rd, 4th, and 5th postoperative days using standard tools, namely the Richmond Agitation Sedation score (RASS) and The Confusion Assessment Method (CAM-ICU). Data were collected based on the presence or absence of delirium. Statistical analysis utilized SPSS version 26.0, employing an independent Student’s t-test for continuous data and chi-square and Fischer’s exact test for categorical data. A p-value ≤ 0.05 was considered statistically significant. Results: Group-A had a mean age of 54.50 ± 17.97, and Group-B had a mean age of 55.22 ± 15.45, both with a male predominance (81.81% and 86.36% respectively). The mean serum cortisol level was significantly higher in Group B (829.71 ± vs. 389.98 ± 68.77). Postoperative delirium occurred in 27.3% of Group B patients, statistically significant compared to the 4.5% in Group A. However, patients in Group B who developed delirium experienced significantly longer postoperative ICU and hospital stays (79.29 ± 12.27 vs. 11.44 ± 2.85, p ≤ 0.05). There was one mortality in Group B, which was statistically not significant. Conclusion: This study observed a significant association between elevated serum cortisol levels in the postoperative period and the occurrence of postoperative delirium after off-pump coronary artery bypass grafting.
文摘Background: Serum albumin, a vital plasma protein, helps maintain intravascular colloidal osmotic pressure, cardiac output, and renal function. Low preoperative serum albumin is linked to poor outcomes, including acute kidney injury (AKI), after off-pump coronary artery bypass (OPCAB) surgery. This study aimed to assess the relationship between preoperative serum albumin levels and early postoperative renal injury. Methods: This prospective comparative cross-sectional study was conducted from August 2019 to February 2021 at the National Heart Foundation Hospital & Research Institute, Bangladesh. It included 160 adult patients with normal preoperative renal function undergoing OPCAB. Patients were divided into two groups: Group A (serum albumin ≥ 4.0 gm/dl) and Group B (serum albumin Results: Preoperative serum albumin was significantly different between groups (Group A: 4.21 ± 0.05 gm/dl, Group B: 3.69 ± 0.04 gm/dl, p = 0.028). Group B had a higher incidence of hypertension (71.25% vs. 51.25%, p st and 3rd postoperative days were higher in Group B (p th day. Postoperative AKI occurred in 18.75% of Group A and 36.25% of Group B. Multivariate regression indicated that low preoperative serum albumin is an independent risk factor for postoperative AKI (p = 0.012, OR = 1.815, CI: 0.675 - 1.162). Conclusion: Preoperative serum albumin level is a valuable predictor of postoperative renal function. Ensuring high normal serum albumin levels before surgery can help minimize the risk of postoperative AKI.
文摘Objectives We report a case in which a patient who suffered from angina secondary to mediastinal irradiation and have been treated by off-pump coronary artery bypass （OPCAB） in our hospital since 3 years ago. A 34-year-old man presented with angina for 8 years after receiving radiation therapy for Hodgkin＇s lymphoma. We retrospectively reviewed all the cases of OPCAB in our hospital and followed-up data for up to 3 years post-operatively. Mediastinal irradiation is probably the cause of significant ostial stenosis of left main coronary and right coronary artery. OPCAB grafting was performed on this patient 3 years ago. His angina disappeared after operation, and he recovered well during follow-up. Conclusions Patients with malignancies who have received mediastinal irradiation should be carefully followed up and routinely screened for the premature development of coronary artery disease. OPCAB may be an appropriate treatment for coronary artery disease caused by mediastinal irradiation.
文摘Background: Off-pump coronary artery bypass grafting (OPCAB) is considered a safer alternative to on-pump surgery, especially in patients with left ventricular dysfunction (LVD). Objectives: This study assessed short-term outcomes and functional improvements in LVD patients post-OPCAB. Methods: The study included 200 coronary artery disease patients who underwent isolated off-pump coronary artery bypass grafting (OPCAB) at the National Heart Foundation Hospital and Research Institute between January 2019 and June 2020. Patients were categorized into Group 1, with a left ventricular ejection fraction (LVEF) of 30% - 39%, and Group 2, with an LVEF of 40% or higher. Echocardiographic assessments of left ventricular dimensions and ejection fraction were performed preoperatively, at discharge, and one month postoperatively. Results: In Group 1, preoperative left ventricular internal dimensions during diastole (LVIDd) and systole (LVIDs) were 53.48 ± 4.40 mm and 44.23 ± 3.93 mm, respectively, with a left ventricular ejection fraction (LVEF) of 35.28% ± 2.26%. At discharge, these values improved to 51.58 ± 4.04 mm (LVIDd), 41.23 ± 5.30 mm (LVIDs), and 39.25% ± 3.75% (LVEF). One month postoperatively, further improvements were observed: 46.29 ± 3.76 mm (LVIDd), 37.45 ± 3.68 mm (LVIDs), and 43.22% ± 4.67% (LVEF). Group 2 showed similar positive outcomes, with preoperative values of 47.09 ± 5.06 mm (LVIDd), 35.11 ± 5.25 mm (LVIDs), and 50.13% ± 7.25% (LVEF), improving to 42.37 ± 4.18 mm (LVIDd), 31.05 ± 4.19 mm (LVIDs), and 55.33% ± 7.05% (LVEF) at one month postoperatively. Both groups demonstrated significant improvements in left ventricular function and NYHA class, with most patients moving from class III/IV to I/II. Complications were minimal, and no mortality was observed. Conclusion: OPCAB is safe and effective for patients with LVEF 30% - 39% and LVEF ≥ 40%, providing significant short-term functional improvements without increased risk.
文摘Objective Metabolic syndrome (MS),a disorder involving multiple metabolic abnormalities such obesity,hypertension,diabetes or abnormal glucose tolerance anddyslipidemia,has been observed in many patients receiving coronary artery bypass procedures.

文摘We sought to assess the incidence of aspirin resistance after off-pump coronary artery bypass （OPCAB） surgery, and investigate whether clopidogrel can improve aspirin response and be safely applied early after OPCAB surgery. Sixty patients who underwent standard OPCAB surgery were randomized into two groups. One group （30 patients） received mono-antiplatelet treatment （MAPT） with aspirin 100 mg daily and the other group received dual anfiplatelet treatment （DAPT） with aspirin 100 mg daily plus clopidogrel 75 mg daily. Platelet aggregations in response to arachi- donic acid （PLAA） and adenosine diphosphate （ADP） （PLADP） were measured preoperatively and on days 1 to 6, 8 and 10 after the antiplatelet agents were administered. A PLAA level above 20% was defined as aspirin resistance. Postoperative bleeding and other perioperative variables were also recorded. There were no significant differences between the two groups in baseline characteristics, average number of distal anastomosis, operation time, postoperative bleeding, ventilation time and postoperative hospital stay. However, the incidence of aspirin resistance was significantly lower in the DAPT group than that in the MAPT group on the first and second day after antiplatelet agents were given （62.1% vs, 32.1%, 34.5% vs. 10.7%, respectively, both P 〈 0.05）. There was no significant difference in postoperative complication between the two groups. DAPT with aspirin and clopidogrel can be safely applied to OPCAB patients early after the procedure. Moreover, clopidogrel reduces the incidence of OPCAB-related aspirin resistance.
文摘Objective To analyze the short-term outcomes of redo coronary artery bypass grafting(CABG) using on-pump and off-pump CABG techniques. Methods From January 2003 to August 2013, non-randomized 80 patients were treated with redo CABG in the Department of Cardiac Surgery, Peking University Third Hospital. Among these patients, 40 underwent on-pump CABG technique(redo-ONCAB group) and 40 underwent off-pump CABG technique(redo-OPCAB group). Furthermore, transmyocardial laser revascularization was performed in high-risk patients who were not suitable to conventional grafting. Clinical data of the two groups were recorded and analyzed including operation time, coronary grafts, incomplete revascularization, postoperative ventilation, perioperative stroke, and low output syndrome, etc. Results There were no significantly differences in age, gender distribution, incidences of hypertension, stroke, and other clinical characteristics between redo-OPCAB group and redo-ONCAB group(all P>0.05), except for incidences of renal dysfunction and pulmonary disease(all P<0.05). The number of grafting vessels in the redo-ONCAB and redo-OPCAB groups was 2.1 ± 0.74 and 1.4 ±0.52 respectively. There was significant difference between the two groups(P=0.0243). Compared with the redo-ONCAB group, there was shorter operation time(P=0.0045), postoperative ventilation(P=0.0211) and intensive care unit stay(P=0.0400), as well as fewer use of platelet(P=0.0338) and blood transfusion(P=0.0034) in the redo-OPCAB group. The incidence of incomplete revascularization(P=0.0253) and the use of transmyocardial laser revascularization(P=0.0052) were higher in the redo-OPCAB group than those in the redo-ONCAB group(all P<0.05). However, no significant differences were showed for the incidence of the use of intra aortic balloon pump and continuous renal replacement therapy, perioperative stroke, low output syndrome, and in-hospital mortality between the two groups(all P>0.05). Conclusion Redo CABG is the safety and efficacy surgical procedure, and redo-OPCAB technique with better outcomes is commended especially in high-risk patients.

文摘The association between atrial fibrillation（AF） after coronary artery bypass grafting（CABG） and the surgical techniques selected has been extensively reported. However, no consistent results were obtained. In the present study, a meta-analysis was conducted by searching the electronic databases Pub Med, Embase, Web of Science, and Cochrane to identify the association of post-CABG AF with on-pump（conventional CABG, c CABG） or off-pump CABG（OPCABG）. Outcomes from randomized clinical trials（RCTs） and propensity score matching（PSM） trials were pooled by using the fixed-effect or the random-effect modeling method, and verified by the quality-effect modeling method. There were 35 studies with 36 independent reports that met the inclusion criteria and were eventually included in our meta-analysis. The total odds ratio（OR） of the incidence of post-CABG AF between OPCABG and c CABG was 0.80（95% CI 0.71–0.91）. The 25 randomized clinical trials（RCTs） had an OR of 0.69（95% CI 0.56–0.86）, while the OR of the 11 PSM trials was 0.88（95% CI 0.77–1.00）. Twenty-six studies involving the patients at a mean age no more than 65 years showed an OR of 0.76（95% CI 0.64–0.90）, whereas 10 studies with patients greater than 65 years old showed an OR of 0.90（95% CI 0.78–1.05）. The results of this meta-analysis suggest that OPCAB surgery may reduce the incidence of post-CABG AF when compared to c CABG and that younger patients may benefit more from OPCAB and have a lower incidence of post-CABG AF.
文摘Objective: Hemodynamic deterioration during positioning of the heart has been the most critical complication of off-pump coronary artery bypass surgery. Pre-operative use of intra-aortic balloon pump has been shown to prevent this complication in high risk patients. The role of balloon pump in high risk patients has been questioned by our group. We modified the role of balloon pump in our patients, thus avoiding the conversion to cardiopulmonary bypass. Methods: 4063 off-pump coronary bypass surgeries were performed by a single surgeon in our center, over thirteen years. 130 intra-aortic balloons used between July 2002 and December 2015 were removed from the the-ater, once the distal anastomosis was performed. We studied this group of patients for—time and need for insertion, duration of balloon used, local insertion problems and survival. Results: Initially, we inserted intra-aortic balloons in high risk patients. We observed that, patients with low ejection fraction and patients with critical left main coronary artery disease were not the ones who actually needed balloon pump support. It was the patients who had ongoing ischemia, with preserved left ventricular function, and ST depression intra-operatively, who needed balloon pump support to perform complete anatomical revascularization. Conclusions: Intra-aortic balloon pump has helped us to position the heart without hemodynamic instability, thereby avoiding conversion to cardio-pulmonary bypass. This enabled us to perform off-pump surgery in virtually all areas of the heart, thus maintaining perfect hemodynamics.

文摘Objective： To compare function recovery of left ventricle after off-pump and on-pump coronary artery bypass （OPCAB and ONCAB） using Tel index. Methods： Twenty-four patients with coronary artery disease were enrolled, twelve of which received OPCAB and the others underwent ONCAB. Left ventricular ejection fraction （LVEF）, E/A ratio at mitral orifice and Tel index were measured using transthoracic echocardiography before surgery and 3-7 days, 1 month, 3 months and 6 months after surgery. Results：Tel index of both groups decreased 3-7 days after surgery, with OPCAB group＇s lower than ONCAB group＇s. The difference between pre-and post-OPCAB was significant （P〈0.01）, but not for ONCAB group （P〈0.05）. Tel index of ONCAB decreased more significant than that of OPCAB 1 month after surgery, there was statistical difference between 3-7 days and 1 month after surgery in ONCAB （P〈0.01）. Afterwards, Tel index of the 2 groups decreased steadily with no significant difference between them at other time points. LVEF and E/A ratio decreased at first, then increased gradually, with no statistical differences between the 2 groups at all time points. Conclusion： The recovery of left ventricular function after OPCAB is earlier than ONCAB. Tel index is more sensitive than LVEF and E/A ratio in detecting cardiac function recoveries and can be considered as an accurate and simple method to evaluate left ventricular systolic and diastolic function.
文摘New surgical techniques for coronary artery bypass graft （CABG） have been explored in order to minimize disfiguring scars, avoid cardiopulmonary bypass and decrease hospital residence and costs etc. Improved surgical expense can perform the procedures in some high-risk patients such as poor left ventricular function, redo CABG, advanced age and renal dysfunction etc. Intraoperatively there is an obligatory period of myocardial ischemia, which may lead to significant hemodynamic consequences. It is a quite challenge to anesthetist in managing the intraoperative patient.
文摘BACKGROUND Coronary artery bypass grafting is a surgical treatment for ischemic heart disease.Although development in surgical technique and improvement of perioperative management reduced the postoperative complications,some patients still delayed in progress of postoperative rehabilitation.In this study,we aimed to investigate the effect of daily intake of an herbal medicine-containing drink for rehabilitation after surgery in patients with ischemic heart disease.AIM To investigate the effect of taking an herbal medicine-containing,commercially available drink for postoperative rehabilitation in those patients.METHODS Patients who underwent isolated off-pump coronary artery bypass(OPCAB)surgery were divided into two groups depend on the timing of the admission to the hospital:the Yunker(YKR)group,that consumed one bottle of a caffeine-free nutritional supplement drink on a daily basis and the control group(CTL)that underwent regular rehabilitation.RESULTS A total of 229 patients(CTL=130,YKR=99)were enrolled.No significant differences were observed in the baseline characteristics between the two groups.The YKR group had a significantly increased number of daily steps postoperatively(P<0.05)and had significantly lower postoperative serum tumor necrosis factor-alpha levels(P<0.01),while no significant differences were observed in the levels of other inflammatory or stress-related cytokines(interleukin-6,adiponectin,superoxide dismutase,and urine 8-hydroxy-2′-deoxyguanosine)between the two groups.Also,the YKR group showed a significant improvement in the Hospital Anxiety and Depression Score(P<0.05).Moreover,there were no differences in postoperative complications and the duration of postoperative hospital stay between the two groups.CONCLUSION Our results demonstrated that the daily intake of an herbal medicine-containing drink after OPCAB surgery may have beneficial effects on cardiac rehabilitation by reducing inflammation markers and depression.
文摘Objectives To investigate the possible role of amino-terminal pro-brain natriuretic peptide （NT-proBNP） in the occurrence of atrial fibrillation （AF） after coronary artery bypass grafting （CABG）. Methods This study group included 70 consecutive patients scheduled for elective off-pump CABG. The patients with ejection fraction （EF） less than 0. 30, history of AF, use of class Ⅰ or Ⅲ antiarrhythmic drug, implanted pacemaker, postoperative myocardial infarction or chest reopening for pericardial tamponade were excluded. Preoperative and postoperative serum NT-proBNP levels were measured by radioimmunoassay technique. Results Postoperative AF occurred in 15 patients （21.4%）; these patients had significantly higher median NT-proBNP levels when compared with those without AF after the operation （ P 〈 0. 01 ）. Using multivariate logistic regression analyses, an increase in NT-proBNP level after CABG was found to be independently associated with AF （ OR = 3.78, 95% IC = 1.81 - 4. 89, P 〈 0. 01 ）. Increased age, diabetes mellitus, preoperative use of β-blocker, proximal right coronary artery involvement, and longer operation time were al- so associated with AF. Conclusions These results indicated that AF was associated with higher NT-proBNP concentrations after off pump CABG; the increase in NT-proBNP after CABG may play an important role in the occurrence of AF after the operation. The further studies are needed to define the reason that lead to higher NT-proBNP concentrations among the patients who present AF after off pump CABG.
文摘Objectives To test the feasibility of the use of high thoracic epidural anesthesia as a sole anesthetic in patients undergoing off pump coronary artery bypass surgery, avoiding general anesthesia. Methods Between October 2002 to April 2003, twenty five cases underwent beating heart coronary artery revascularization without endotracheal general anesthesia, using high thoracic epidural anesthesia and analgesia. All the patients underwent epidural catheterization on the evening before the surgery. Resuits The patients in all received 71 grafts (single n = 11, double n = 5, triple n = 6, quadruple n = 3). Six patients underwent repeat coronary artery bypass. Except one was converted to general anesthesia and cardiopulmonary bypass, the other patients underwent off-pump coronary artery bypass graft surgery, 2 patients underwent grafting via left thoracotomy (MIDCAB) and the rest through mid sternotomy. There was no mortality. Mean length of stay in the intensive care unit was 16 .2 ( 4.2 hours and hospital was 3.0(1.2 days. Conclusions Our experience confirms the feasibility of performing multiple coronary artery bypasses in conscious patients without endotracheal general anesthesia
文摘BACKGROUND Some patients with coronary atherosclerotic heart disease experience major adverse cardiac events(MACE)and require readmission after Coronary Artery Bypass Grafting(CABG)surgery.This is often attributed to patients'unhealthy lifestyles and dietary habits,inadequate understanding of the disease,and poor disease management compliance.Thus,searching for more targeted nursing intervention models that can enhance patients'self-management abilities and reduce the risk of readmission after CABG surgery is significant.AIM To observe the impact of specialized nursing outpatient case management on patients after CABG surgery.METHODS A total of 103 patients who underwent CABG surgery in our hospital between April 2021 and April 2022 comprised the study sample.The patients were divided into two groups using an odd-even number grouping method.The control group received routine nursing care,while the case management group received specialized nursing outpatient case management.The differences in psychological status,adherence to medical treatment,self-care ability,knowledge mastery,quality of life scores,and the occurrence rate of MACE were compared between the two groups.RESULTS After the intervention,the case management group had lower scores on the selfrating depression scale and self-rating anxiety scale and lower MACE rate,as well as higher scores for adherence to a healthy diet,medication adherence,good lifestyle habits,regular exercise,and timely follow-up,higher scores on the Coronary Heart Disease Self-Management Scale,higher scores for managing adverse habits,symptoms,emotional cognition,emergency response,disease knowledge,general lifestyle,and treatment adherence,higher scores for understanding coronary heart disease,recognizing the importance of medication adherence,understanding selfcare points after CABG surgery,and being aware of post-CABG precautions,higher scores for physical well-being,disease condition,general health,social-psychological well-being,and work-related aspects(P<0.05).CONCLUSION Specialized nursing outpatient case management can enhance patient adherence to medical treatment,knowledge mastery,psychological well-being,and overall quality of life in patients after CABG surgery.
文摘The major source of morbidity following cardiopulmonary bypass (CPB) is the systemic inflammatory response (SIRS response) which leads to multiple derangements in different organ systems. To combat this, miniaturized cardiopulmonary bypass circuits (MCPBC) have been created to lessen the inflammatory response to CPB. Here we examine early outcomes following coronary artery bypass grafting (CABG) using a MCPBC system compared to conventional bypass techniques at a single institution. Methods: 60 consecutive patients undergoing elective CABG were prospectively enrolled. Nine patients underwent coronary artery bypass grafting (CABG) with conventional CPB (cCABG), 33 underwent off-pump CABG (OPCAB), and the remaining 18 patients underwent CABG with a MCPBC system. Demographics and outcomes were compared between groups and statistical analyses applied. Results: No significant difference was observed in mortality between groups, with only one death reported in total. Morbidity was also low, totaling only 6.7%, with none occurring in the MCPBC group. The MCPBC group required less PRBC and total blood product transfusion than the cCABG and OPCABG groups (p = 0.05), but changes in PLT and Hct over time were not different between groups. Conclusions: The MCPBC system was shown to be comparable to conventional bypass and OPCABG in terms of postoperative complications and mortality. Furthermore, the MCPBC system had the advantage of a decreased transfusion requirement. Based on our preliminary observations, this mini-cardiopulmonary bypass circuit provides a safe alternative to conventional bypass techniques.
文摘BACKGROUND One of the major perioperative complications for coronary artery bypass graft(CABG)is stroke.The risk of perioperative stroke after CABG is approximately 2%.Carotid stenosis(CS)is considered an independent predictor of perioperative stroke risk in CABG patients.The optimal management of such patients has been a source of controversy.One of the possible surgical options is synchronous carotid endarterectomy(CEA)and CABG.Here,we have presented 4 cases of successful synchronous CEA and CABG.Our center’s experience with 4 cases of significant carotid artery stenosis,which were successfully managed with combined CEA and CABG,are detailed.The first case was a female who presented for CABG after a ST-elevation myocardial infarction.She had right internal carotid artery(ICA)occlusion and 90%left ICA stenosis.The second case was a male who was electively admitted for CABG.It was discovered that he had left ICA occlusion and 90%right ICA stenosis.The third case was a male with a history of stroke,two months prior to admission.He presented with non-ST-elevation myocardial infarction.Preoperatively,it was discovered that he had>90%right ICA stenosis.The final case was a male who was electively admitted for CABG.It was discovered that he had bilateral>90%ICA stenosis.We have also reviewed the current evidence and guidelines for managing CS in patients undergoing CABG.CONCLUSION Our case series demonstrated that synchronous CEA and CABG was safe.A multicenter study with additional patients is needed.It is necessary for clinicians to screen for CS in high-risk patients with features.
