Cardiac thrombi can often mimic cardiac tumors on imaging, creating a diagnostic challenge. Primary cardiac tumors are rare and usually benign, whereas most cardiac tumors result from metastases, commonly originating from malignancies in the breast, lung, or melanoma. Aim: This report highlights the importance of distinguishing various cardiac masses based on clinical presentations, clinical courses, and radiological features. Case Presentation: We describe two cases of cardiac masses with unique and diverse clinical features. Each case posed significant diagnostic challenges due to their distinct presentations and clinical progressions. Conclusion: These cases underscore the importance of considering both benign and metastatic origins in the differential diagnosis of intracavitary cardiac masses. Accurate differentiation between thrombi and tumors is crucial for appropriate management and treatment.展开更多

We hypothesized the chronic inflammatory state of CRF patients may lead to cardiac sympathetic remodeling, increasing the incidence of ventricular arrhythmia(VA) and sudden cardiac death. And explored the role of atorvastatin and etanercept in this process.METHODS A total of 48 rats were randomly divided into sham operation group(Sham group), CRF group, CRF + atorvastatin group(CRF + statin group), and CRF + etanercept group(CRF + rhTNFR-Fcgroup). Sympathetic nerve remodeling was assessed by immunofluorescence of growth-associated protein 43(GAP-43) and tyrosine hydroxylase positive area fraction. Electrophysiological testing was performed to assess the incidence of VA by assessing the ventricular effective refractory period and ventricular fibrillation threshold. The levels of tumor necrosis factor-alpha(TNF-α) and interleukin-1beta were determined by Western blotting and enzyme-linked immunosorbent assay.RESULTS Echocardiogram showed that compared with the Sham group, left ventricular end-systolic diameter and ventricular weight/body weight ratio were significantly higher in the CRF group. Hematoxylin-eosin and Masson staining indicated that myocardial fibers were broken, disordered, and fibrotic in the CRF group. Western blotting, enzyme-linked immunosorbent assay,immunofluorescence and electrophysiological examination suggested that compared with the Sham group, GAP-43 and TNF-α proteins were significantly upregulated, GAP-43 and tyrosine hydroxylase positive nerve fiber area was increased, and ventricular fibrillation threshold was significantly decreased in the CRF group. The above effects were inhibited in the CRF + statin group and the CRF + rhTNFR-Fcgroup.CONCLUSIONS In CRF rats, TNF-α was upregulated, cardiac sympathetic remodeling was more severe, and the nephrogenic cardiac sympathetic remodeling existed. Atorvastatin and etanercept could downregulate the expression of TNF-α or inhibit its activity, thus inhibited the above effects, and reduced the occurrence of VA and sudden cardiac death.展开更多

To show its interest in the African context, in the management of heart disease, a prospective study was carried out. Its objective was to evaluate the effects of physical rehabilitation on cardiac function. Methods: Patients were evaluated at the beginning and at the end of cardiovascular rehabilitation by cardiovascular, biological, and echocardiographic parameters including the size of the heart chambers, the kinetics of the walls, and the systolic function of the ventricles. Results: The study involved 12 patients, 67% of whom were men. After cardiac rehabilitation, the mean hemodynamic constants had not been significantly modified. However, a significant decrease in Total-Cholesterol, LDL-Cholesterol and triglyceride levels was noted. Mean fasting blood sugar decreased from 1.25 ± 0.48 g/L to 0.92 ± 0.18 g/L and glycated hemoglobin from 7.72% ± 0.01% to 6.45% ± 0.008%. The echocardiographic parameters studied showed an improvement in the dilation of the heart chambers in 8.33% of the patients, the normalization of the ejection fraction of the left ventricle in 16% patients, the improvement of the kinetic disorders in 16% of patients and recovery of right ventricular systolic function in all patients. Conclusion: Cardiac rehabilitation as a secondary preventive measure for cardiovascular disease has contributed significantly to improving the clinico-biological parameters of the disease.展开更多

However, Terminalia mantaly H. Perrier could present potential health effects on patients. In order to determine the possible cardiotoxic effects of the hydro-alcoholic extract of the bark of Terminalia mantaly H. Perrier, (HAEBTM) forty (40) rats distributed randomly into 4 groups, including 10 animals per group (5 males and 5 females) were used. Animals in group 1 received distilled water and were used as a control group. On the other hand, groups 2, 3, 4 received oral administration a volume of the hydroalcoholic extract of Terminalia mantaly H. Perrier corresponding to 1 mL/100g of body weight at 150 mg/kg, 300 mg/kg, 600 mg/kg, respectively. The extract was administered daily at the same time for 28 days and serum was collected once a week to evaluate cardiac biochemical markers using spectrophotometric methods using a Cobas C311 HITACHI biochemistry system. After one month of study, all rats were euthanized by overdose of ether, and the hearts of the rats were removed for gross morphological and histopathological analysis. Results were analysed using variance analysis (ANOVA) to compare outcomes as a function of doses administered and treatment times. The biochemical parameters ALT, LDH, CPK, CPKMB showed no significant change (p Terminalia mantaly showed no lesions, edema and necrosis. These results suggest that the hydroalcoholic extract of Terminalia mantaly did not interfere with the functioning or alter the integrity of the heart.展开更多

Cardiac rehabilitation (CR) is currently a crucial component in managing this condition. The aim was to assess the effects of cardiac rehabilitation on physical capacity of heart failure patients. Methods: This was a cross-sectional study conducted from February 1, 2021, to June 30, 2023. We included all patients with heart failure who underwent cardiac rehabilitation. Data analysis was performed using SPSS software version 24.0, with a significance level set at p Results: The study included 87 heart failure patients, with a male-to-female ratio of 1.8. Mean age was 57.10 years (±11.75). Coronary artery disease was the primary cause of heart failure, accounting for 75.9% of cases. Atrial fibrillation was present in 4.7% of cases. Following cardiac rehabilitation, Left Ventricular Ejection Fraction increased from 40.15% to 49.48% (p = 0.001). Resting heart rate decreased significantly from 81.4 bpm to 68.3 bpm (p = 0.000), and the number of METS increased from 4.3 to 6.57 (+56.8%;p = 0.000). The mean distance covered in the 6-minute walk test significantly increased from 337.8 meters to 522.7 meters (p = 0.000), reflecting a gain of 183.5 meters. Moreover, the increase in the number of METS was more pronounced in females (p = 0.001), non-obese individuals (p = 0.000), non-diabetics (p = 0.001), non-sedentary individuals (p = 0.000), and non-smokers (p = 0.000). The study reported a low readmissions rate of 2.2% and a mortality rate of 1.1%. Conclusion: Our study demonstrates that cardiac rehabilitation is beneficial for black African heart failure patients, resulting in significant improvements in symptoms, physical and capacity.展开更多

文摘Background: The differential diagnosis for intracavitary cardiac masses is limited, typically including vegetations, tumors, or thrombi. Cardiac thrombi can often mimic cardiac tumors on imaging, creating a diagnostic challenge. Primary cardiac tumors are rare and usually benign, whereas most cardiac tumors result from metastases, commonly originating from malignancies in the breast, lung, or melanoma. Aim: This report highlights the importance of distinguishing various cardiac masses based on clinical presentations, clinical courses, and radiological features. Case Presentation: We describe two cases of cardiac masses with unique and diverse clinical features. Each case posed significant diagnostic challenges due to their distinct presentations and clinical progressions. Conclusion: These cases underscore the importance of considering both benign and metastatic origins in the differential diagnosis of intracavitary cardiac masses. Accurate differentiation between thrombi and tumors is crucial for appropriate management and treatment.
文摘The post-resuscitation period is recognized as the main predictor of cardiopul-monary resuscitation(CPR)outcomes.The first description of post-resuscitation syndrome and stony heart was published over 50 years ago.Major manifestations may include but are not limited to,persistent precipitating pathology,systemic ischemia/reperfusion response,post-cardiac arrest brain injury,and finally,post-cardiac arrest myocardial dysfunction(PAMD)after successful resuscitation.Why do some patients initially survive successful resuscitation,and others do not?Also,why does the myocardium response vary after resuscitation?These ques-tions have kept scientists busy for several decades since the first successful resuscitation was described.By modifying the conventional modalities of resu-scitation together with new promising agents,rescuers will be able to salvage the jeopardized post-resuscitation myocardium and prevent its progression to a dismal,stony heart.Community awareness and staff education are crucial for shortening the resuscitation time and improving short-and long-term outcomes.Awareness of these components before and early after the restoration of circulation will enhance the resuscitation outcomes.This review extensively addresses the underlying pathophysiology,management,and outcomes of post-resuscitation syndrome.The pattern,management,and outcome of PAMD and post-cardiac arrest shock are different based on many factors,including in-hospital cardiac arrest vs out-of-hospital cardiac arrest(OHCA),witnessed vs unwitnessed cardiac arrest,the underlying cause of arrest,the duration,and protocol used for CPR.Although restoring spontaneous circulation is a vital sign,it should not be the end of the game or lone primary outcome;it calls for better understanding and aggressive multi-disciplinary interventions and care.The development of stony heart post-CPR and OHCA remain the main challenges in emergency and critical care medicine.

文摘International guidelines for post-cardiac arrest care recommend using multi-modal strategies to avoid the withdrawal of life-sustaining therapy(WLST)in patients with the potential for neurological recovery.[1]However,a clear methodology for multi-modal approaches has yet to be developed.Neuron-specific enolase(NSE)is currently the only recommended biomarker,and the European Resuscitation Council(ERC)and the European SocietyofIntensiveCareMedicine(ESICM)have proposed a cutoff value of 60μg/L at 48 and/or 72 h after the return of spontaneous circulation(ROSC)as a multimodal prognostic tool for predicting poor neurological outcomes.
文摘The Annual Report on Cardiovascular Health and Diseases in China(2022)intricate landscape of cardiovascular health in China.In connection with the previous section,this seventh section of the report offers a comprehensive analysis of dis-orders of heart rhythm in China.In 2021,China has achieved significant development and gratifying results in many aspects of the field of arrhythmia.Left bundle branch pacing(LBBP),as an emerging pacing technique originating from China,has received widespread attention.New research results have emerged on its indications,surgical procedures,clinical evaluation,and com-parison with other pacing techniques.Its feasibility,effectiveness,and safety have been basically verified,but its long-term pro-gnosis still needs further confirmation from larger samples and longer follow-up time research results.Leadless pacemakers have begun to be used in a wider range of clinical applications,and related large sample cohort studies have been reported.In addi-tion,there are also noteworthy new achievements in the fields of pacemaker remote programming,anticoagulation and radiofre-quency catheter ablation(RFCA)therapy for atrial fibrillation,and implantable cardioverter defibrillator prevention of sudden cardiac death.In terms of clinical practice,due to COVID-19 pandemic,the number of RFCA procedures and other device im-plantations in China has fluctuated,but it has gradually recovered since 2020.
文摘Paragangliomas,also known as pheochromocytomas(1–9 cases per million),arise in the paraganglia.[1]Pheochromocytomas occur in the adrenal glands,while paragangliomas occur elsewhere.[2]Paragangliomas originate from paraganglion cells,which are derived from the neural ectoderm of the nerves and migrate along both sides of the median axis from the base of the skull to the pelvis during embryonic development.
文摘Cardiac tumors are rare.However,cardiac metastases can occur in up to 10%of patients with cancer.Among cardiac neoplasms,metastases are much more common than primary cardiac tumors.[1]Metastatic cardiac neoplasms most frequently metastasize from the respiratory system.

文摘BACKGROUND Chronic renal failure(CRF) patients are predisposed to arrhythmias, while the detailed mechanisms are unclear. We hypothesized the chronic inflammatory state of CRF patients may lead to cardiac sympathetic remodeling, increasing the incidence of ventricular arrhythmia(VA) and sudden cardiac death. And explored the role of atorvastatin and etanercept in this process.METHODS A total of 48 rats were randomly divided into sham operation group(Sham group), CRF group, CRF + atorvastatin group(CRF + statin group), and CRF + etanercept group(CRF + rhTNFR-Fcgroup). Sympathetic nerve remodeling was assessed by immunofluorescence of growth-associated protein 43(GAP-43) and tyrosine hydroxylase positive area fraction. Electrophysiological testing was performed to assess the incidence of VA by assessing the ventricular effective refractory period and ventricular fibrillation threshold. The levels of tumor necrosis factor-alpha(TNF-α) and interleukin-1beta were determined by Western blotting and enzyme-linked immunosorbent assay.RESULTS Echocardiogram showed that compared with the Sham group, left ventricular end-systolic diameter and ventricular weight/body weight ratio were significantly higher in the CRF group. Hematoxylin-eosin and Masson staining indicated that myocardial fibers were broken, disordered, and fibrotic in the CRF group. Western blotting, enzyme-linked immunosorbent assay,immunofluorescence and electrophysiological examination suggested that compared with the Sham group, GAP-43 and TNF-α proteins were significantly upregulated, GAP-43 and tyrosine hydroxylase positive nerve fiber area was increased, and ventricular fibrillation threshold was significantly decreased in the CRF group. The above effects were inhibited in the CRF + statin group and the CRF + rhTNFR-Fcgroup.CONCLUSIONS In CRF rats, TNF-α was upregulated, cardiac sympathetic remodeling was more severe, and the nephrogenic cardiac sympathetic remodeling existed. Atorvastatin and etanercept could downregulate the expression of TNF-α or inhibit its activity, thus inhibited the above effects, and reduced the occurrence of VA and sudden cardiac death.
文摘BACKGROUND Cardiovascular disease,particularly myocardial infarction(MI)profound impact on patients'quality of life and places a substantial burden on the healthcare and economy systems.Developments in medical technology have led to the emer-gence of coronary intervention as an essential method for treating MI.AIM To assess the effects of cardiac rehabilitation care on cardiac function recovery and negative emotions in MI after coronary intervention.METHODS This study included a total of 180 patients with MI during the period from June 2022 to July 2023.Selected patients were divided into two groups:An observation group,which receiving cardiac rehabilitation care;a control group,which re-ceiving conventional care.By comparing multiple observation indicators such as cardiac function indicators,blood pressure,exercise tolerance,occurrence of adverse cardiac events,and negative emotion scores between the two groups of patients.All the data were analyzed and compared between two groups.RESULTS There were 44 males and 46 females in the observation group with an average age of 36.26±9.88 yr;there were 43 males and 47 females in the control group,with an average age of 40.87±10.5 yr.After receiving the appropriate postoperative nursing measures,the results of the observation group showed significant improvement in several indicators compared with the control group.Indicators of cardiac function,such as left ventricular end-diastolic internal diameter and left ventricular ejection fraction were significantly better in the observation group than in the control group(P<0.05).Exercise endurance assessment showed that the 6-minute walking test distance was significantly increased in the patients of the observation group(P<0.01).In addition,the incidence of adverse cardiac events was significantly lower in the observation group,and negative mood scores were significantly reduced(P<0.05).CONCLUSION Cardiac rehabilitation care after coronary intervention has a significant positive impact on functional recovery.This emphasizes the importance of cardiac rehabilitation care to improve patient recovery.
文摘Cardiac rehabilitation helps improve the prognosis and quality of life for patients with heart disease. To show its interest in the African context, in the management of heart disease, a prospective study was carried out. Its objective was to evaluate the effects of physical rehabilitation on cardiac function. Methods: Patients were evaluated at the beginning and at the end of cardiovascular rehabilitation by cardiovascular, biological, and echocardiographic parameters including the size of the heart chambers, the kinetics of the walls, and the systolic function of the ventricles. Results: The study involved 12 patients, 67% of whom were men. After cardiac rehabilitation, the mean hemodynamic constants had not been significantly modified. However, a significant decrease in Total-Cholesterol, LDL-Cholesterol and triglyceride levels was noted. Mean fasting blood sugar decreased from 1.25 ± 0.48 g/L to 0.92 ± 0.18 g/L and glycated hemoglobin from 7.72% ± 0.01% to 6.45% ± 0.008%. The echocardiographic parameters studied showed an improvement in the dilation of the heart chambers in 8.33% of the patients, the normalization of the ejection fraction of the left ventricle in 16% patients, the improvement of the kinetic disorders in 16% of patients and recovery of right ventricular systolic function in all patients. Conclusion: Cardiac rehabilitation as a secondary preventive measure for cardiovascular disease has contributed significantly to improving the clinico-biological parameters of the disease.
文摘Terminalia mantaly H. Perrier is a plant used in traditional medicine for the treatment of various pathologies. However, Terminalia mantaly H. Perrier could present potential health effects on patients. In order to determine the possible cardiotoxic effects of the hydro-alcoholic extract of the bark of Terminalia mantaly H. Perrier, (HAEBTM) forty (40) rats distributed randomly into 4 groups, including 10 animals per group (5 males and 5 females) were used. Animals in group 1 received distilled water and were used as a control group. On the other hand, groups 2, 3, 4 received oral administration a volume of the hydroalcoholic extract of Terminalia mantaly H. Perrier corresponding to 1 mL/100g of body weight at 150 mg/kg, 300 mg/kg, 600 mg/kg, respectively. The extract was administered daily at the same time for 28 days and serum was collected once a week to evaluate cardiac biochemical markers using spectrophotometric methods using a Cobas C311 HITACHI biochemistry system. After one month of study, all rats were euthanized by overdose of ether, and the hearts of the rats were removed for gross morphological and histopathological analysis. Results were analysed using variance analysis (ANOVA) to compare outcomes as a function of doses administered and treatment times. The biochemical parameters ALT, LDH, CPK, CPKMB showed no significant change (p Terminalia mantaly showed no lesions, edema and necrosis. These results suggest that the hydroalcoholic extract of Terminalia mantaly did not interfere with the functioning or alter the integrity of the heart.
文摘Background: Heart failure is a chronic and severe condition that often results from various heart diseases. Cardiac rehabilitation (CR) is currently a crucial component in managing this condition. The aim was to assess the effects of cardiac rehabilitation on physical capacity of heart failure patients. Methods: This was a cross-sectional study conducted from February 1, 2021, to June 30, 2023. We included all patients with heart failure who underwent cardiac rehabilitation. Data analysis was performed using SPSS software version 24.0, with a significance level set at p Results: The study included 87 heart failure patients, with a male-to-female ratio of 1.8. Mean age was 57.10 years (±11.75). Coronary artery disease was the primary cause of heart failure, accounting for 75.9% of cases. Atrial fibrillation was present in 4.7% of cases. Following cardiac rehabilitation, Left Ventricular Ejection Fraction increased from 40.15% to 49.48% (p = 0.001). Resting heart rate decreased significantly from 81.4 bpm to 68.3 bpm (p = 0.000), and the number of METS increased from 4.3 to 6.57 (+56.8%;p = 0.000). The mean distance covered in the 6-minute walk test significantly increased from 337.8 meters to 522.7 meters (p = 0.000), reflecting a gain of 183.5 meters. Moreover, the increase in the number of METS was more pronounced in females (p = 0.001), non-obese individuals (p = 0.000), non-diabetics (p = 0.001), non-sedentary individuals (p = 0.000), and non-smokers (p = 0.000). The study reported a low readmissions rate of 2.2% and a mortality rate of 1.1%. Conclusion: Our study demonstrates that cardiac rehabilitation is beneficial for black African heart failure patients, resulting in significant improvements in symptoms, physical and capacity.

文摘Cardiac tumors are neoplasms involving heart structures at any level,meaning the myocardium,valves,and cardiac chambers.When considering cardiac masses,it is not uncommon for surgeons to be surprised when they diagnose one.The real incidence of this complex group of diseases has been explored only after cardiac diagnostic tools became more appropriate.Despite differential diagnosis being relevant,surgical indication is usually requested for all malignant cardiac tumors and also for many types of benign tumors.The development of cardiac imaging techniques,therefore,has been the key point for a better understanding of the history of cardiac tumors and especially of the relevance of surgical indication in such conditions.Systematic and combined applications of echocardiography,cardiac computed tomography and magnetic resonance allow in the majority of case a clear definition of the nature of a newly discovered cardiac mass.The presence of a Li-Fraumeni syndrome seems to be the trigger aspect in accelerating the propensity of developing a cardiac tumor.Despite the revolutionary usefulness of the cardiac imaging techniques available,it is still considered a hazard to diagnose a malignant cardiac mass just with radiological imaging;the mainstay of the final diagnosis stands in surgical excision of the mass and histopathological report.
