[Methods] 100 patients diagnosed with acute heart failure and hospitalized in the internal medicine-cardiovascular department in The First People s Hospital of Yulin from January 2019 to February 2020 were randomly divided into two groups, 50 cases in each group. Both groups were treated with conventional anti-heart failure drugs. The control group was given levosimendan once, and the observation group was given levosimendan three times, with an interval of one month. The creatinine (Cr) level, serum NT proBNP, left ventricular ejection fraction (LVEF) and left ventricular end diastolic diameter (LVEDD) were observed at 48 h before and after treatment and one month and two months after treatment in both groups. [Results] Compared with before treatment, the levels of NT-proBNP decreased in the two groups at 48 h after treatment, and the difference was statistically significant ( P <0.05). The Cr level of the control group did not change significantly before and after treatment, and the Cr level of the observation group decreased at one and two months after treatment compared with before treatment, with statistically significant differences ( P <0.05). Compared with before treatment, NT-proBNP and LVEDD decreased and LVEF increased at one and two months after treatment, and the differences were statistically significant ( P <0.05). There were no obvious adverse reactions in the two groups of patients during the treatment. [Conclusions] Repetitive use of levosimendan in the treatment of acute heart failure could significantly improve the renal function, cardiac contractility and cardiac function of patients, and with the passage of time, the treatment effect was improved, which is worthy of clinical promotion.展开更多

Among the available imaging modalities, echocardiography is the method of choice due to its feasibility and cost-effectiveness. Lung ultrasonography in emergency department, critical and cardiac care units is becoming popular. The present study aimed to assess the value of the focused echocardiography and lung ultrasound protocol for guiding treatment and its effect on the hospitalization period in AHF patients admitted to the CCU, 6 months re-hospitalization and mortality. Methods: This study included 40 consecutive patients admitted to the Cardiology and Angiology department after disposition from the emergency department at Alexandria main university hospital in Egypt with the diagnosis of (AHF). Patients were divided into 2 groups, 20 patients received the standard treatment while the other group received a modification of medication doses according to daily imaging changes. All patients were followed up for 6 months to assess the 6 months HF rehospitalization and death rates. Results: Group II patients had a significantly shorter duration of hospitalization;6.45 ± 2.01 days compared to 9.10 ± 3.82 days among group I patients (P = 0.02). There was no significant difference between the two groups regarding the 6 months rehospitalization and death rates. Conclusion: The focused echocardiography and lung ultrasound-guided therapy for AHF patients resulted in a shorter duration of hospitalization without increased adverse events.展开更多

The correct risk stratification of patients could improve clinical outcome and resources allocation,avoiding the overtreatment of low-risk subjects or the early,inappropriate discharge of high-risk patients. Many clinical scores have been derived and validated for in-hospital and post-discharge survival; predictive models include demographic,clinical,hemodynamic and laboratory variables. Data sets are derived from public registries,clinical trials,and retrospective data. Most models show a good capacity to discriminate patients who reach major clinical end-points,with C-indices generally higher than 0.70,but their applicability in realworld populations has been seldom evaluated. No study has evaluated if the use of risk score-based stratification might improve patient outcome. Some variables(age,blood pressure,sodium concentration,renal function) recur in most scores and should always be considered when evaluating the risk of an individual patient hospitalized for acute heart failure. Future studies will evaluate the emerging role of plasma biomarkers.展开更多

However, the diagnostic value of ultrasound lung comets(ULCs) for acute heart failure(AHF) performed in busy emergency department(ED) is uncertain. The present meta-analysis aimed to assess the diagnostic efficiency of ULCs in AHF. Methods We conducted a search on online journal databases to collect the data on TLS performed for diagnosing AHF published up to the end of July 2017. The sensitivity, specificity, positive likelihood ratio(PLR), negative likelihood ratio(NLR), and summary receiver operating characteristic(SROC) curve were calculated. The post-test probability of AHF was calculated by using Bayes analysis. Results We enrolled a total of 15 studies involving 3,309 patients. The value of sensitivity, specificity, PLR, NLR, DOR, area under the SROC curve, and Q* index was 85%, 91%, 8.94, 0.14, 67.24, 0.9587, and 0.9026, respectively. We detected significant heterogeneity among included studies, and therefore, all these results were analyzed under the random-effect model. We also explored possible sources of heterogeneity among the studies by using meta-regression analysis. Results suggest that the time interval between patient's admission to bedside TLS examination was closely related to TLS accuracy. Conclusion This meta-analysis demonstrated that detecting ULCs is a convenient bedside tool and has high accuracy for early AHF diagnosis in ED. TLS could be recommended to be applied for early diagnosis of AHF in ED.展开更多

However, their use as a first line treatment of acute heart failure is firmly established in clinical practice, and endorsed in clinical guidelines. Loop diuretics are typically the first line diuretic strategy for the treatment of acute heart failure. For patients with considerable fluid retention, there is some evidence that initial treatment with continuous infusion or boluses of high dose loop diuretic is superior to an initial lower dose strategy. In patients who are diuretic resistant, the addition of an oral thiazide or thiazide-like diuretic to induce sequential nephron blockade can be beneficial. Intravenous low-dose dopamine has also been used to assist diuresis and preserve renal function in such circumstances, but trials are underway to confirm the clinical value of this agent. Mechanical ultrafiltration has been used to treat patients with heart failure and fluid retention, but the evidence base is not secure, and its place in clinical practice is yet to be established.展开更多

These patients have very high short-term (2-6 months) mortality and readmission rates, while the healthcare system incurs substantial costs. Until recently, the clinical characteristics, management patterns, and outcomes of these patients have been poorly understood and, in consequence, risk stratification for these patients has not been well defined. Several risk prediction models that can accurately identify high-risk patients have been developed in the last year using data from clinical trials, large registries or administrative databases. Use of multi-variable risk models at the time of hospital admission or discharge offers better risk stratification and should be encouraged, as it allows for appropriate allocation of existing resources and development of clinical trials testing new treatment strategies for patients admitted with AHFS. The emerging observation that the prognosis for the ensuing three to six months may be obtained at presentation for AHFS has major implications for development of future therapies.展开更多

Recently, it has been shown that the use of a highly sensitive,non-invasive device measuring lung impedance(LI) reduces hospitalizations for heart failure(HF); it has also been shown that this device reduces the cardiovascular and all-cause mortality of stable HF patients when used in longterm out-patient follow-ups. The aim of these case series is to demonstrate the potential additive role of non-invasive home LI monitoring in the early postdischarge period.CASE SUMMARY We present a case series of three patients who had performed daily LI measurements at home using the edema guard monitor(EGM) during 30 d after an episode of AHF. All patients had a history of chronic ischemic HF with a reduced ejection fraction and were hospitalized for 6–17 d. LI measurements were successfully made at home by patients with the help of their caregivers. The patients were carefully followed up by HF specialists who reacted to the values of LI measurements, blood pressure, heart rate and clinical symptoms. LI reduction was a more frequent trigger to medication adjustments compared to changes in symptoms or vital signs. Besides, LI dynamics closely tracked the use and dose of diuretics.CONCLUSION Our case series suggests non-invasive home LI monitoring with EGM to be a reliable and potentially useful tool for the early detection of congestion or dehydration and thus for the further successful stabilization of a HF patient after a worsening episode.展开更多

Although chronic heart failure (CHF) therapies are continuously evolving based on the increasing understanding of the involved etiology, acute heart failure (AHF) therapies are still based on hemodynamic improvements and symptom alleviation. Guidelines on AHF management have highlighted that the currently administered AHF therapies lack evidence and have raised concerns on the safety and efficacy of some of the hitherto accepted treatment modalities. Additionally, the high mortality and morbidity rates associated with the current AHF therapies also add to the imperative need to revisit AHF management. The last decade has witnessed a paradigm shift in the way we define and diagnose AHF. Apart from it being recognized as a distinct clinical entity, research has also led to new data on the pathophysiological changes associated with AHF. These developments along with the limited short- and long-term effects of currently used therapies may herald a paradigm shift in the way we plan and deliver management strategies to treat the pathological progression of heart failure.展开更多

Despite multiple different beneficial medications for the treatment of chronic CHF, there are no therapies with a demonstrated mortality benefit in the treatment of acute decompensated heart failure. In fact, studies of inotropes used in this setting have demonstrated more harm than good. Arginine vasopressin has been shown to be up regulated in CHF. When bound to the V1 a and/or V2 receptors, vasopressin causes vasoconstriction, left ventricular remodeling and free water reabsorption. Recently, two drugs have been approved for use that antagonize these receptors. Studies thus far have indicated that these medications, while effective at aquaresis(free water removal), are safe and not associated with increased morbidity such as renal failure and arrhythmias. Both conivaptan and tolvaptan have been approved for the treatment of euvolemic and hypervolemic hyponatremia. We review the results of these studies in patients with heart failure.展开更多

The patients in the two groups were given routine treatments after admission. On this basis, the patients in the observation group were given non-invasive ventilator. The patients in the control group were given continuous low flow oxygen inhalation. PaO2, pH, PaCO2, SaO2, and PaO2/FiO2 before and after treatment between the two groups were compared. The serum NT-pro BNP and cTnI levels before treatment, 24 h and 48 h after treatment in the two groups were compared.Results:The comparison of PaO2, pH, PaCO2, SaO2, and PaO2/FiO2 before treatment between the two groups was not statistically significant. PaO2, pH, SaO2, and PaO2/FiO2 after treatment in the two groups were significantly elevated, while PaCO2 was significantly reduced when compared with before treatment. PaO2, pH, SaO2, and PaO2/FiO2 after treatment in the observation group were significantly higher than those in the control group, while PaCO2 was significantly lower than that in the control group. The comparison of NT-pro BNP and cTnI levels before treatment between the two groups was not statistically significant. NT-pro BNP and cTnI levels 12 h and 24 h after treatment in the two groups were significantly elevated when compared with before treatment. NT-pro BNP and cTnI levels 12 h and 24 h after treatment in the observation group were significantly lower than those in the control group.Conclusions:Non-invasive ventilator in the treatment of acute heart failure merged with respiratory failure can effectively improve the ventilation function, reduce NT-pro BNP and cTnI levels, and is of great significance in enhancing the rescued effect.展开更多

Here, we present a previously healthy 45-year-old man, who was admitted with pericardial effusion and symptoms of acute heart failure. CMR followed by targeted left ventricular endomyocardial biopsy(EMB) revealed the diagnosis of isolated SHD. The combined use of CMR and EMB was crucial in diagnosing SHD. Furthermore, this case report demonstrates the value of CMR for monitoring response to therapy and lesion healing.展开更多

Prompt diagnosis or exclusion of HF and its cause and precipitating factors can improve the quality and efficiency of care, shorten hospital stay, reduce readmission and improve prognosis. While the clinician remains central to reaching a clinical diagnosis of heart failure, the use of traditional and novel diagnostic technologies will improve the specificity and sensitivity of the diagnosis of heart failure diagnosis and provide insights into its pathophysiogical profile and help tailor therapy to individual patient need. Chest X-rays and electrocardiograms are generally available;echocardiograms less so. Novel technologies include both invasive and non-invasive methods to detect increases in intrathoracic fluid, pulmonary congestion, left ventricular filling pressures, cardiac output and vascular function. However, few of these technologies have been subjected to randomised controlled trials investigating their ability to improve patient management.展开更多

Peripartum cardiomyopathy (PPCM) is rare but it is one of major causes of maternal death. We experienced a pregnant patient with severe aortic regurgitation (AR) presented symptoms of acute heart failure. Her heart failure was not better after an emergency cesarean section and aortic valve replacement (AVR) therefore we think that PPCM caused her heart failure. Case presentation: A 35-year-old woman diagnosed as having severe AR became pregnant. No changes in the AR were apparent during pregnancy. However, the patient developed symptoms of acute heart failure at 37 weeks of gestation, and an emergency cesarean section was performed under general anesthesia. Her hemodynamic status worsened after the cesarean section, and AVR was performed. She was supported with percutaneous cardiopulmonary support (PCPS) after the operation. As recovery seemed to take longer than usual, we decided to implant a ventricular assist device (VAD). Her condition improved after VAD placement, but then she died from a cerebral infarction. In this case, the heart failure was an acute-onset even though AR was stable before and after the pregnancy, and the heart failure did not improve after AVR. Therefore, we concluded that PPCM, rather than AR caused her heart failure. Conclusions: We encountered a case of a pregnant patient with severe AR who presented with symptoms of acute heart failure caused by PPCM. The effect of AR to her heart failure could not be easily denied. This delayed the diagnosis of PPCM, which in turn delayed our decision to use a VAD. Therefore, PPCM should be considered when pregnant patients with heart disease present symptoms of heart failure.展开更多

文摘BACKGROUND Heart failure(HF)causes extracardiac organ congestion,including in the hepatic portal system.Reducing venous congestion is essential for HF treatment,but evaluating venous congestion is sometimes difficult in patients with chronic HF.The portal vein(PV)flow pattern can be influenced by right atrial pressure.Ultrasound images of the PV are quite easy to obtain and are reproducible among sonographers.However,the association between PV pulsatility and the condition of HF remains unclear.We hypothesize that PV pulsatility at discharge reflects the condition of HF.AIM To evaluate the usefulness of PV pulsatility as a prognostic marker for hospit-alized patients with acute HF.METHODS This observational study was conducted from April 2016 to January 2017 and April 2018 to April 2019 at Shinko Hospital.We enrolled 56 patients with acute HF,and 17 patients without HF served as controls.PV flow velocity was mea-sured by ultrasonography on admission and at discharge.We calculated the PV pulsatility ratio(PVPR)as the ratio of the difference between the peak and minimum velocity to the peak velocity.The primary endpoint was cardiac death and HF re-hospitalization.The observation period was 1 year from the first hospitalization.The Kaplan-Meier method was used to determine the stratified composite event-free rates,and the log-rank test was used for comparisons between groups.RESULTS On admission,the PVPR was significantly higher in patients with acute HF than controls(HF:0.29±0.20 vs controls:0.08±0.07,P<0.01).However,the PVPR was significantly decreased after the improvement in HF(admission:0.29±0.20 vs discharge:0.18±0.15,P<0.01)due to the increase in minimum velocity(admission:12.6±4.5 vs discharge:14.6±4.6 cm/s,P=0.03).To elucidate the association between the PVPR and cardiovascular outcomes,the patients were divided into three groups according to the PVPR tertile at discharge(PVPR-T1:0≤PVPR≤0.08,PVPR-T2:0.08<PVPR≤0.21,PVPR-T3:PVPR>0.21).The Kaplan-Meier analysis showed that patients with a higher PVPR at discharge had the worst prognosis among the groups.CONCLUSION PVPR at discharge reflects the condition of HF.It is also a novel prognostic marker for hospitalized patients with acute HF.
文摘Tumor necrosis factor inhibitors(anti-TNFs)are widely used therapies for the treatment of inflammatory bowel diseases(IBD);however,their administration is not risk-free.Heart failure(HF),although rare,is a potential adverse event related to administration of these medications.However,the exact mechanism of development of HF remains obscure.TNFαis found in both healthy and damaged hearts.Its effects are concentration-and receptor-dependent,promoting either cardio-protection or cardiomyocyte apoptosis.Experimental rat models with TNFαreceptor knockout showed increased survival rates,less reactive oxygen species formation,and improved diastolic left ventricle pressure.However,clinical trials employing anti-TNF therapy to treat HF had disappointing results,suggesting abolishment of the cardioprotective properties of TNFα,making cardiomyocytes susceptible to apoptosis and oxidation.Thus,patients with IBD who have risk factors should be screened for HF before initiating anti-TNF therapy.This review aims to discuss adverse events associated with the administration of anti-TNF therapy,with a focus on HF,and propose some approaches to avoid cardiac adverse events in patients with IBD.
文摘Background: Acute heart failure (AHF) is a life-threatening condition that necessitates urgent evaluation and treatment with an urgent need for hospital admission. Among the available imaging modalities, echocardiography is the method of choice due to its feasibility and cost-effectiveness. Lung ultrasonography in emergency department, critical and cardiac care units is becoming popular. The present study aimed to assess the value of the focused echocardiography and lung ultrasound protocol for guiding treatment and its effect on the hospitalization period in AHF patients admitted to the CCU, 6 months re-hospitalization and mortality. Methods: This study included 40 consecutive patients admitted to the Cardiology and Angiology department after disposition from the emergency department at Alexandria main university hospital in Egypt with the diagnosis of (AHF). Patients were divided into 2 groups, 20 patients received the standard treatment while the other group received a modification of medication doses according to daily imaging changes. All patients were followed up for 6 months to assess the 6 months HF rehospitalization and death rates. Results: Group II patients had a significantly shorter duration of hospitalization;6.45 ± 2.01 days compared to 9.10 ± 3.82 days among group I patients (P = 0.02). There was no significant difference between the two groups regarding the 6 months rehospitalization and death rates. Conclusion: The focused echocardiography and lung ultrasound-guided therapy for AHF patients resulted in a shorter duration of hospitalization without increased adverse events.

文摘Background:The clinical efficiency of routine oxygen therapy is uncertain in patients with acute heart failure(AHF)who do not have hypoxemia.The aim of this study was to investigate the association between oxygen therapy and clinical outcomes in normoxemic patients hospitalized with AHF using real-world data.Methods:Normoxemic patients diagnosed with AHF on intensive care unit(ICU)admission from the electronic ICU(eICU)Collaborative Research Database were included in the current study,in which the study population was divided into the oxygen therapy group and the ambient air group.Propensity score matching(PSM)was applied to create a balanced covariate distribution between patients receiving supplemental oxygen and those exposed to ambient air.Linear regression and logistic regression models were performed to assess the associations between oxygen therapy and length of stay(LOS),and all-cause in-hospital as well as ICU mortality rates,respectively.A series of sensitivity and subgroup analyses were conducted to further validate the robustness of our findings.Results:A total of 2922 normoxemic patients with AHF were finally included in the analysis.Overall,42.1%(1230/2922)patients were exposed to oxygen therapy,and 57.9%(1692/2922)patients did not receive oxygen therapy(defined as the ambient air group).After PSM analysis,1122 pairs of patients were matched:each patient receiving oxygen therapy was matched with a patient without receiving supplemental oxygen.The multivariable logistic model showed that there was no significant interaction between the ambient air and oxygen therapy for all-cause in-hospital mortality[odds ratio(OR)=1.30;95%confidence interval(CI)0.92–1.82;P=0.138]or ICU mortality(OR=1.39;95%CI 0.83–2.32;P=0.206)in the post-PSM cohorts.In addition,linear regression analysis revealed that oxygen therapy was associated with prolonged ICU LOS(OR=1.11;95%CI 1.06–1.15;P<0.001)and hospital LOS(OR=1.06;95%CI 1.01–1.10;P=0.009)after PSM.Furthermore,the absence of an effect of supplemental oxygen on mortality was consistent in all subgroups.Conclusions:Routine use of supplemental oxygen in AHF patients without hypoxemia was not found to reduce all cause in-hospital mortality or ICU mortality.
文摘Acute heart failure is a leading cause of hospitalization and death,and it is an increasing burden on health care systems. The correct risk stratification of patients could improve clinical outcome and resources allocation,avoiding the overtreatment of low-risk subjects or the early,inappropriate discharge of high-risk patients. Many clinical scores have been derived and validated for in-hospital and post-discharge survival; predictive models include demographic,clinical,hemodynamic and laboratory variables. Data sets are derived from public registries,clinical trials,and retrospective data. Most models show a good capacity to discriminate patients who reach major clinical end-points,with C-indices generally higher than 0.70,but their applicability in realworld populations has been seldom evaluated. No study has evaluated if the use of risk score-based stratification might improve patient outcome. Some variables(age,blood pressure,sodium concentration,renal function) recur in most scores and should always be considered when evaluating the risk of an individual patient hospitalized for acute heart failure. Future studies will evaluate the emerging role of plasma biomarkers.

文摘Objective A new technique of transthoracic lung ultrasonography(TLS) has emerged and demonstrated promising results in acute heart failure diagnosis at an early stage. However, the diagnostic value of ultrasound lung comets(ULCs) for acute heart failure(AHF) performed in busy emergency department(ED) is uncertain. The present meta-analysis aimed to assess the diagnostic efficiency of ULCs in AHF. Methods We conducted a search on online journal databases to collect the data on TLS performed for diagnosing AHF published up to the end of July 2017. The sensitivity, specificity, positive likelihood ratio(PLR), negative likelihood ratio(NLR), and summary receiver operating characteristic(SROC) curve were calculated. The post-test probability of AHF was calculated by using Bayes analysis. Results We enrolled a total of 15 studies involving 3,309 patients. The value of sensitivity, specificity, PLR, NLR, DOR, area under the SROC curve, and Q* index was 85%, 91%, 8.94, 0.14, 67.24, 0.9587, and 0.9026, respectively. We detected significant heterogeneity among included studies, and therefore, all these results were analyzed under the random-effect model. We also explored possible sources of heterogeneity among the studies by using meta-regression analysis. Results suggest that the time interval between patient's admission to bedside TLS examination was closely related to TLS accuracy. Conclusion This meta-analysis demonstrated that detecting ULCs is a convenient bedside tool and has high accuracy for early AHF diagnosis in ED. TLS could be recommended to be applied for early diagnosis of AHF in ED.
文摘The evidence base for the use of diuretics in acute heart failure is limited, with no large double-blind placebo-controlled randomized trials. However, their use as a first line treatment of acute heart failure is firmly established in clinical practice, and endorsed in clinical guidelines. Loop diuretics are typically the first line diuretic strategy for the treatment of acute heart failure. For patients with considerable fluid retention, there is some evidence that initial treatment with continuous infusion or boluses of high dose loop diuretic is superior to an initial lower dose strategy. In patients who are diuretic resistant, the addition of an oral thiazide or thiazide-like diuretic to induce sequential nephron blockade can be beneficial. Intravenous low-dose dopamine has also been used to assist diuresis and preserve renal function in such circumstances, but trials are underway to confirm the clinical value of this agent. Mechanical ultrafiltration has been used to treat patients with heart failure and fluid retention, but the evidence base is not secure, and its place in clinical practice is yet to be established.
文摘Each year, there are over one million hospitalizations for acute heart failure syndrome (AHFS) in the United States alone,with a similar number in Western Europe. These patients have very high short-term (2-6 months) mortality and readmission rates, while the healthcare system incurs substantial costs. Until recently, the clinical characteristics, management patterns, and outcomes of these patients have been poorly understood and, in consequence, risk stratification for these patients has not been well defined. Several risk prediction models that can accurately identify high-risk patients have been developed in the last year using data from clinical trials, large registries or administrative databases. Use of multi-variable risk models at the time of hospital admission or discharge offers better risk stratification and should be encouraged, as it allows for appropriate allocation of existing resources and development of clinical trials testing new treatment strategies for patients admitted with AHFS. The emerging observation that the prognosis for the ensuing three to six months may be obtained at presentation for AHFS has major implications for development of future therapies.

文摘BACKGROUND Patients discharged after hospitalization for acute heart failure(AHF) are frequently readmitted due to an incomplete decongestion, which is difficult to assess clinically. Recently, it has been shown that the use of a highly sensitive,non-invasive device measuring lung impedance(LI) reduces hospitalizations for heart failure(HF); it has also been shown that this device reduces the cardiovascular and all-cause mortality of stable HF patients when used in longterm out-patient follow-ups. The aim of these case series is to demonstrate the potential additive role of non-invasive home LI monitoring in the early postdischarge period.CASE SUMMARY We present a case series of three patients who had performed daily LI measurements at home using the edema guard monitor(EGM) during 30 d after an episode of AHF. All patients had a history of chronic ischemic HF with a reduced ejection fraction and were hospitalized for 6–17 d. LI measurements were successfully made at home by patients with the help of their caregivers. The patients were carefully followed up by HF specialists who reacted to the values of LI measurements, blood pressure, heart rate and clinical symptoms. LI reduction was a more frequent trigger to medication adjustments compared to changes in symptoms or vital signs. Besides, LI dynamics closely tracked the use and dose of diuretics.CONCLUSION Our case series suggests non-invasive home LI monitoring with EGM to be a reliable and potentially useful tool for the early detection of congestion or dehydration and thus for the further successful stabilization of a HF patient after a worsening episode.
文摘It has become increasingly apparent that the looming epidemic of heart failure calls for systematic treatment approaches tailored to the needs of individual patient phenotypes. Although chronic heart failure (CHF) therapies are continuously evolving based on the increasing understanding of the involved etiology, acute heart failure (AHF) therapies are still based on hemodynamic improvements and symptom alleviation. Guidelines on AHF management have highlighted that the currently administered AHF therapies lack evidence and have raised concerns on the safety and efficacy of some of the hitherto accepted treatment modalities. Additionally, the high mortality and morbidity rates associated with the current AHF therapies also add to the imperative need to revisit AHF management. The last decade has witnessed a paradigm shift in the way we define and diagnose AHF. Apart from it being recognized as a distinct clinical entity, research has also led to new data on the pathophysiological changes associated with AHF. These developments along with the limited short- and long-term effects of currently used therapies may herald a paradigm shift in the way we plan and deliver management strategies to treat the pathological progression of heart failure.
文摘Congestive heart failure(CHF) is one of the most common reasons for hospitalization in the United States. Despite multiple different beneficial medications for the treatment of chronic CHF, there are no therapies with a demonstrated mortality benefit in the treatment of acute decompensated heart failure. In fact, studies of inotropes used in this setting have demonstrated more harm than good. Arginine vasopressin has been shown to be up regulated in CHF. When bound to the V1 a and/or V2 receptors, vasopressin causes vasoconstriction, left ventricular remodeling and free water reabsorption. Recently, two drugs have been approved for use that antagonize these receptors. Studies thus far have indicated that these medications, while effective at aquaresis(free water removal), are safe and not associated with increased morbidity such as renal failure and arrhythmias. Both conivaptan and tolvaptan have been approved for the treatment of euvolemic and hypervolemic hyponatremia. We review the results of these studies in patients with heart failure.
文摘Objective:To observe the application effect of non-invasive ventilator in the treatment of acute heart failure merged with respiratory failure in ICU.Methods:A total of 80 patients with acute heart failure merged with respiratory failure who were admitted in ICU from January, 2015 to January, 2016 were included in the study and randomized into the observation group and the control group with 40 cases in each group. The patients in the two groups were given routine treatments after admission. On this basis, the patients in the observation group were given non-invasive ventilator. The patients in the control group were given continuous low flow oxygen inhalation. PaO2, pH, PaCO2, SaO2, and PaO2/FiO2 before and after treatment between the two groups were compared. The serum NT-pro BNP and cTnI levels before treatment, 24 h and 48 h after treatment in the two groups were compared.Results:The comparison of PaO2, pH, PaCO2, SaO2, and PaO2/FiO2 before treatment between the two groups was not statistically significant. PaO2, pH, SaO2, and PaO2/FiO2 after treatment in the two groups were significantly elevated, while PaCO2 was significantly reduced when compared with before treatment. PaO2, pH, SaO2, and PaO2/FiO2 after treatment in the observation group were significantly higher than those in the control group, while PaCO2 was significantly lower than that in the control group. The comparison of NT-pro BNP and cTnI levels before treatment between the two groups was not statistically significant. NT-pro BNP and cTnI levels 12 h and 24 h after treatment in the two groups were significantly elevated when compared with before treatment. NT-pro BNP and cTnI levels 12 h and 24 h after treatment in the observation group were significantly lower than those in the control group.Conclusions:Non-invasive ventilator in the treatment of acute heart failure merged with respiratory failure can effectively improve the ventilation function, reduce NT-pro BNP and cTnI levels, and is of great significance in enhancing the rescued effect.
文摘This case report illustrates challenging aspects of diagnosis and treatment of isolated sarcoid heart disease(SHD) and the role of cardiovascular magnetic resonance(CMR) imaging. Here, we present a previously healthy 45-year-old man, who was admitted with pericardial effusion and symptoms of acute heart failure. CMR followed by targeted left ventricular endomyocardial biopsy(EMB) revealed the diagnosis of isolated SHD. The combined use of CMR and EMB was crucial in diagnosing SHD. Furthermore, this case report demonstrates the value of CMR for monitoring response to therapy and lesion healing.
文摘Acute or worsening heart failure is a common reason for hospitalization which carries a high mortality. Prompt diagnosis or exclusion of HF and its cause and precipitating factors can improve the quality and efficiency of care, shorten hospital stay, reduce readmission and improve prognosis. While the clinician remains central to reaching a clinical diagnosis of heart failure, the use of traditional and novel diagnostic technologies will improve the specificity and sensitivity of the diagnosis of heart failure diagnosis and provide insights into its pathophysiogical profile and help tailor therapy to individual patient need. Chest X-rays and electrocardiograms are generally available;echocardiograms less so. Novel technologies include both invasive and non-invasive methods to detect increases in intrathoracic fluid, pulmonary congestion, left ventricular filling pressures, cardiac output and vascular function. However, few of these technologies have been subjected to randomised controlled trials investigating their ability to improve patient management.
文摘Introduction: Knowledge of the risks of pregnancy with heart disease is important because the maternal mortality is much higher than the average. Peripartum cardiomyopathy (PPCM) is rare but it is one of major causes of maternal death. We experienced a pregnant patient with severe aortic regurgitation (AR) presented symptoms of acute heart failure. Her heart failure was not better after an emergency cesarean section and aortic valve replacement (AVR) therefore we think that PPCM caused her heart failure. Case presentation: A 35-year-old woman diagnosed as having severe AR became pregnant. No changes in the AR were apparent during pregnancy. However, the patient developed symptoms of acute heart failure at 37 weeks of gestation, and an emergency cesarean section was performed under general anesthesia. Her hemodynamic status worsened after the cesarean section, and AVR was performed. She was supported with percutaneous cardiopulmonary support (PCPS) after the operation. As recovery seemed to take longer than usual, we decided to implant a ventricular assist device (VAD). Her condition improved after VAD placement, but then she died from a cerebral infarction. In this case, the heart failure was an acute-onset even though AR was stable before and after the pregnancy, and the heart failure did not improve after AVR. Therefore, we concluded that PPCM, rather than AR caused her heart failure. Conclusions: We encountered a case of a pregnant patient with severe AR who presented with symptoms of acute heart failure caused by PPCM. The effect of AR to her heart failure could not be easily denied. This delayed the diagnosis of PPCM, which in turn delayed our decision to use a VAD. Therefore, PPCM should be considered when pregnant patients with heart disease present symptoms of heart failure.
