Abstract

:Chagas heart disease (HD) is a chronic fibrosing myocarditis with high mortality. The PEACH study aimed to evaluate if exercise training can improve the functional capacity of Chagas HD patients with left ventricular dysfunction and/or heart failure. The PEACH study was a single center, parallel-group, clinical trial that randomized 30 clinical stable Chagas HD patients with left ventricular ejection fraction <45% or heart failure symptoms to either supervised exercise training 3 times/week for 6 months or a control group. Both groups had the same monthly pharmaceutical and nutritional counseling and usual care. Primary end point was functional capacity assessed by peak exercise oxygen consumption (peak VO2) obtained by cardiopulmonary exercise test. Secondary end points included other cardiopulmonary exercise test variables, cardiac function by echocardiography, body composition, muscle respiratory strength, and metabolic biomarkers. Peak VO2 increased among patients in exercise group from 17.60 ± 4.65 mlO2 kg-1 min-1 to 19.40 ± 5.51 mlO2 kg-1 min-1 while decreased in controls from 15.40 ± 6.30 mlO2 kg-1 min-1 to 12.96 ± 4.50 mlO2 kg-1 min-1, resulting in significant difference in change in peak VO2 between groups after 6 months (β = +4.6, p = 0.004). There were significant differences between groups in changes in anaerobic threshold (β = 3.7, p = 0.05), peak oxygen pulse (β = +2.7, p = 0.032) and maximum minute ventilation (β = +13.9, p < 0.0001) after 6 months of intervention. In conclusion, exercise training improved functional capacity of chronic Chagas HD patients with left ventricular dysfunction and/or heart failure.

摘要

: 恰加斯心脏病 (Chagas heart disease,HD) 是一种慢性纤维化心肌炎,死亡率高。PEACH研究旨在评估运动训练是否可以改善伴有左心室功能障碍和/或心力衰竭的Chagas HD患者的功能能力。PEACH研究是一项单中心、平行组的临床试验,将30名左心室射血分数 <45% 或有心力衰竭症状的临床稳定的Chagas HD患者随机分组,接受3次/周监督运动训练,持续6个月或对照组。两组每月进行相同的药物和营养咨询和常规护理。主要终点是通过心肺运动试验获得的峰值运动耗氧量 (峰值VO2) 评估的功能能力。次要终点包括其他心肺运动试验变量、超声心动图测定的心脏功能、身体成分、肌肉呼吸强度和代谢生物标志物。运动组患者的VO2峰值从min-1的17.60 ± 4.65 mlO2 kg-1增加到min-1的19.40 ± 5.51 mlO2 kg-1,而对照组从min-1的15.40 ± 6.30 mlO2 kg-1降低到min-1的12.96 ± 4.50 mlO2 kg-1。导致6个月后组间VO2峰值变化有显著性差异 (β   =   + 4.6,p   =   0.004)。干预6个月后无氧阈 (β   =   3.7,p   =   0.05) 、峰值氧脉冲 (β   =   + 2.7,p   =   0.032) 、最大分钟通气量 (β   =   + 13.9,p <0.0001) 变化组间差异有统计学意义。总之,运动训练改善了伴有左心室功能障碍和/或心力衰竭的慢性Chagas HD患者的功能能力。

METHODS::Aim: Heart failure is a serious complication of acute myocardial infarction leading to poor prognosis. We aimed at exploring time trends of heart failure and their impact on mortality among patients with an incident acute myocardial infarction. Methods: From the National Patient Danish Registry we collected data on all patients hospitalized with an incident of acute myocardial infarction during 2000-2009 and identified cases with in-hospital heart failure (presented on admission or developing heart failure during acute myocardial infarction hospitalization) or post-discharge heart failure (a hospitalization or outpatient visit following acute myocardial infarction discharge), and assessed in-hospital, 30-day and 1-year mortality. Results: Of the 78,814 patients included in the study, 10,248 (13.0%) developed in-hospital heart failure. The odds of in-hospital heart failure declined 0.9% per year (odds ratio=0.991, 95% confidence interval: 0.983-0.999). In-hospital heart failure was associated with 13% (odds ratio=1.13, 95% confidence interval: 1.06-1.20) and 14% (odds ratio=1.14, 95% confidence interval: 1.07-1.20) higher in-hospital and 30-day mortality, respectively. Of the 61,637 patients discharged alive without in-hospital heart failure, 5978 (9.7%) experienced post-discharge heart failure, 4116 (6.7%) were hospitalized and 1862 (3.0%) were diagnosed at outpatient clinics. The risk of heart failure requiring hospitalization declined 5.5% per year (hazard ratio=0.945, 95% confidence interval: 0.934-0.955) whereas the risk of heart failure diagnosed at outpatient clinics increased 13.4% per year (hazard ratio=1.134, 95% confidence interval: 1.115-1.153). Post-discharge heart failure was associated with 239% (hazard ratio=3.39, 95% confidence interval: 3.18-3.63) higher 1-year mortality. Conclusions: In-hospital and post-discharge heart failure requiring hospitalization decreased whereas post-discharge heart failure diagnosed at outpatient clinics increased among incident acute myocardial infarction patients during 2000-2009. The development of heart failure, especially after acute myocardial infarction discharge, indicates a poor prognosis.

METHODS::The number of patients with heart failure (HF) is rapidly increasing. Although hypertension is related to onset of HF, antihypertensive treatment status for these patients has not been fully examined. We conducted a claims-based study to discern the treatment status of Japanese hypertensive patients with HF. Two Japanese databases (2008-2016) from acute care hospitals and health insurance societies were used to analyze prescription rates for antihypertensive drug class or category of diuretics in all hypertensive patients and the subset of patients with HF. Totals of hypertensive patients and those with HF in each database in 2015 were 4,191,666 and 1,404,008 patient-months, and 1,382,732 and 148,194 patient-months, respectively. In the acute care hospitals database, calcium channel blockers (CCBs) (55.0-56.5%) and angiotensin II receptor blockers (49.4-54.7%) were prescribed most. β-blockers (38.7-48.0%) and diuretics (42.3-45.6%) were prescribed more for hypertensive patients with HF than for all hypertensive patients (21.5-24.8% and 25.5-26.7%, respectively). Loop diuretics were also prescribed more often for hypertensive patients with HF (68.3-76.0% from acute care hospitals and 47.8-55.8% from health insurance societies) than for all hypertensive patients (56.7-61.7% and 16.4-18.3%). The size of medical institution had a greater effect on drug selection than patient age in both patient groups. Given recommendations in guidelines for hypertensive patients with HF, the differences in drug choice in comparison with all hypertensive patients appear reasonable. However, some deviations, such as the high rate of CCBs in frontline and preference for angiotensin II receptor blockers over angiotensin-converting enzyme inhibitors, did not appear to follow guidelines.

METHODS::The management of type 2 diabetes mellitus (T2DM) essentially consists in controlling hyperglycaemia, together with other vascular risk factors, in order to reduce the incidence and severity of diabetic complications. Whereas glucose control using classical glucose-lowering agents (except perhaps metformin) largely fails to reduce cardiovascular disease (CVD), two new pharmacological classes, glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium-glucose cotransporter type 2 inhibitors (SGLT2is), have proven their ability to reduce major cardiovascular events in patients with established CVD. Furthermore, SGLT2is reduced the risk of hospitalisation for heart failure and the progression of renal disease. According to the 2018 ADA-EASD consensus report, the choice of a second agent to be added to metformin should now be driven by the presence or not of atherosclerotic CVD, heart failure or renal disease, all conditions that should promote the use of a SGLT2i or a GLP-1 RA with proven efficacy. Thus endocrinologists have to face a new paradigm in the management of T2DM, with a shift from a primary objective of glucose control without inducing hypoglycaemia and weight gain to a goal of cardiovascular and renal protection, largely independent of glucose control. Of note, however, the latter remains crucial to reduce the risk of microangiopathy.

心力衰竭方向

心力衰竭(heart failure)简称心衰,是指由于心脏的收缩功能和(或)舒张功能发生障碍,不能将静脉回心血量充分排出心脏,导致静脉系统血液淤积,动脉系统血液灌注不足,从而引起心脏循环障碍症候群。此种障碍症候群集中表现为肺淤血、腔静脉淤血。心力衰竭并不是一个独立的疾病,而是心脏疾病发展的终末阶段。其中绝大多数的心力衰竭都是以左心衰竭开始的,即首先表现为肺循环淤血。
