Background Withdrawal of optimal medical therapy has been reported to relapse cardiac dysfunction in patients with dilated cardiomyopathy (DCM) whose cardiac function had improved. However, it is unknown whether beta‐blockers can prevent deterioration of cardiac function in those patients. We examined the effect of beta‐blockers on left ventricular ejection fraction (LVEF) in recovered DCM. Methods and Results We analyzed the clinical personal record of DCM, a national database of the Japanese Ministry of Health, Labor and Welfare, between 2003 and 2014. Recovered DCM was defined as a previously documented LVEF <40% and a current LVEF ≥40%. Patients with recovered DCM were divided into 2 groups according to the use of beta‐blockers. A one‐to‐one propensity case‐matched analysis was used. The primary outcome was defined as a decrease in LVEF >10% at 2 years of follow‐up. Of 5370 eligible patients, 4104 received beta‐blockers. Propensity score matching yielded 1087 pairs. Mean age was 61.9 years, and 1619 (74.5%) were men. Mean LVEF was 49.3±8.2%, and median B‐type natriuretic peptide was 46.6 (interquartile range, 18.0–118.1) pg/mL. The primary outcome was observed less frequently in the beta‐blocker group than in the no‐beta‐blocker group (19.6% versus 24.0%; odds ratio [OR], 0.77; 95% CI, 0.63–0.95; P =0.013). Subgroup analysis demonstrated that female patients (women: OR, 0.54; 95% CI, 0.36–0.81; men: OR, 0.88; 95% CI, 0.69–1.12; P for interaction=0.040) were benefited by beta‐blockers. Conclusions Beta‐blocker use could prevent deterioration of left ventricular systolic function in patients with recovered DCM.

Abstract Background Withdrawal of optimal medical therapy has been reported to relapse cardiac dysfunction in patients with dilated cardiomyopathy (DCM) whose cardiac function had improved. However, it is unknown whether beta-blockers can prevent deterioration of cardiac function in those patients. Purpose We examined the effect of beta-blockers on left ventricular ejection fraction (LVEF) in recovered DCM. Methods We analyzed the clinical personal records of DCM, a national database of Japanese Ministry of Health, Labor and Welfare, between 2003 and 2014. Recovered DCM was defined as a previously documented LVEF &lt;40% and a current LVEF ≥40%. Patients with recovered DCM were divided into two groups according to the use of beta-blockers. The primary outcome was defined as a decrease in LVEF &gt;10% at two years of follow-up. A one to one propensity case-matched analysis was used. A per-protocol analysis was also performed. Considering intra- and inter-observer variability of echocardiographic evaluations, we also examined outcomes by multivariable logistic regression model after changing the inclusion criteria as follows; (1) previous LVEF &lt;40% and current LVEF ≥40%; (2) previous LVEF &lt;35% and current LVEF ≥40%; (3) previous LVEF &lt;30% and current LVEF ≥40%; (4) previous LVEF &lt;40% and current LVEF ≥50%. Outcomes were also changed as (1) decrease in LVEF ≥5% (2) decrease in LVEF ≥10% (3) decrease in LVEF ≥15%. The analysis of outcomes by using combination of multiple imputation and inverse probability of treatment weighting was also conducted to assess the effects of missing data and selection bias attributable to propensity score matching on outcomes. Results From 2003 to 2014, 40,794 consecutive patients with DCM were screened. Out of 5,338 eligible patients, 4,078 received beta-blockers. Propensity score matching yielded 998 pairs. Mean age was 61.7 years and 1,497 (75.0%) was male. Mean LVEF was 49.1±8.1%. The primary outcome was observed less frequently in beta-blocker group than in no beta-blocker group (18.0% vs. 23.5%; odds ratio [OR] 0.72; 95% confidence interval [CI] 0.58–0.89; P=0.003). The prevalence of increases in LVDd (11.5% vs. 15.8%; OR 0.70; 95% CI 0.54–0.91; P=0.007) and LVDs (23.1% vs. 27.2%; OR 0.80; 95% CI 0.65–0.99; P=0.041) was also lower in the beta-blocker group. Similar results were obtained in per-protocol analysis. These results were robust to several sensitivity analyses. As a result of preventing a decrease in LVEF, the deterioration to HFrEF was also prevented by the use of beta-blocker (23.6% vs. 30.6%). Subgroup analysis demonstrated that beta-blocker prevented decrease in LVEF regardless of atrial fibrillation. Conclusion Use of beta-blocker was associated with prevention of decrease in left ventricular ejection fraction in patients with recovered DCM.

Introduction: Recent investigation has identified that discontinuation of beta-blockers in subjects with normal left ventricular ejection fraction (LVEF) leads to a reduction in natriuretic peptide levels. We investigated whether a similar trend would be seen in a hypertension clinical trial cohort. Methods: In 9,012 subjects hypertensive subjects without a history of symptomatic heart failure, known LVEF <35% or recent heart failure hospitalization enrolled in the Systolic Blood Pressure Intervention Trial (SPRINT), we compared incidence of loop diuretic initiation and time to initiation following start of a new anti-hypertensive medication. The categorical relationship (new antihypertensive class followed by loop-diuretic use) and temporal relationship (time to loop diuretic initiation) were each analyzed. The categorical relationship was assessed using a Pearson’s chi-squared test and the temporal relationship using a Wilcoxon rank sum test. Bonferroni-corrected p-values were utilized for all comparisons. Results: Among the 9,012 subjects analyzed, the incidence of anti-hypertensive initiation and loop diuretic initiation was greatest following start of a beta-blocker (16.6%) compared with other antihypertensive medication classes (calcium channel blocker 13.8%, angiotensin converting enzyme-inhibitor/angiotensin receptor blocker 12.9% and thiazide diuretic 10.2%; p<0.001). In addition, the median time between starting a new antihypertensive medication and loop diuretic was the shortest for beta-blockers and longest for thiazides (both p <0.01). No significant differences in renal function were identified between groups. Conclusion: Compared to other major classes of hypertensive agents, starting beta-blockers was associated with more common and earlier initiation of a loop diuretics in a population without heart failure at baseline. This finding may suggest beta-blocker induced heart failure in a population with a predominantly normal ejection fraction.

Introduction: Central sleep apnea (CSA) is a common complication in heart failure patients (HF) and closely associated with poor prognosis. Adaptive servo-ventilation (ASV) is a new treatment for HF with CSA. Some study indicated ASV might improve cardiac function and its prognosis. However, there was little discussion by each background disease. Methods and Results: We examined 64 HF with CSA patients (involving 15 dilated cardiomyopathy (DCM) patients, 27 ischemic cardiomyopathy (ICM) patients, and 22 heart failure with preserved ejection fraction (HFpEF) patients) treated with ASV who had not been admitted to the hospital due to worsening HF in the 6 months before initiating ASV therapy. During 1 and 6 months observation, apnia-hypopnea index and brain natriuretic peptide were decreased significantly than baseline in all groups. There was similar in left ventricular ejection fraction in ICM and HFpEF groups during observation, however, in DCM group, there was significantly improved (29.3 +/- 14.3 to 36.5 +/- 12.4, and to 40.5 +/- 14.9%, P<0.01 compared with baseline). And left ventricular end systolic diameter was significantly shortened (53.7 +/- 11.1 to 30.4 +/- 11.5, and to 47.6 +/- 12.0 mm, P<0.01 compared with baseline), in spite of left ventricular end diastolic diameter was not changed. Conclusions: These results indicate that ASV is more effective in DCM patient with modifying hemodynamics and cardiac function than ICM and HFpEF patients.

Background/Aims: High ADAMTS-7 levels are associated with acute myocardial infarction (AMI), although its involvement in ventricular remodeling is unclear. In this study, we investigated the association between ADAMTS-7 expression and cardiac function in a rat AMI model. Methods: Sprague-Dawley rats were randomized into AMI (n = 40) and sham (n = 20) groups. The left anterior descending artery was sutured to model AMI. Before surgery and 7, 14, 28, and 42 days post-surgery, ADAMTS-7 and brain natriuretic peptide (BNP), and cartilage oligomeric matrix protein (COMP) were assessed by ELISA, western blot, real-time RT-PCR, and/or immunohistochemistry. Cardiac functional and structural parameters were assessed by M-mode echocardiography. Results: After AMI, plasma ADAMTS-7 levels increased, peaking on day 28 (AMI: 13.2 ± 6.3 vs. sham: 3.4 ± 1.3 ng/ml, P < 0.05). Compared with the sham group, ADAMTS-7 expression was higher in the infarct zone at day 28. COMP present in normal myocardium was degraded by day 28 post-AMI. Plasma ADAMTS-7 correlated positively with BNP (r = 0.642, P = 0.025), left ventricular end-diastolic diameter (r = 0.695, P = 0.041), left ventricular end-systolic diameter (r = 0.710, P = 0.039), left ventricular ejection fraction (r = 0.695, P = 0.036), and left ventricular short-axis fractional shortening (r = 0.721, P = 0.024). Conclusions: ADAMTS-7 levels may reflect the degree of ventricular remodeling after AMI.

Abstract Background The use of preoperative beta-blockers has been accepted as a quality standard for patients undergoing coronary artery bypass graft (CABG) surgery. However, conflicting results from recent studies have raised questions concerning the effectiveness of this quality metric. We sought to determine the influence of preoperative beta-blocker administration before CABG in patients with left ventricular dysfunction. Methods The authors analyzed all cases of isolated CABGs in patients with left ventricular ejection fraction less than 50%, performed between 2012 January and 2017 June, at 94 centres recorded in the China Heart Failure Surgery Registry database. In addition to the use of multivariate regression models, a 1–1 propensity scores matched analysis was performed. Results Of 6116 eligible patients, 61.7% received a preoperative beta-blocker. No difference in operative mortality was found between two cohorts (3.7% for the non-beta-blockers group vs. 3.0% for the beta-blocker group; adjusted odds ratio [OR] 0.82 [95% CI 0.58–1.15]). Few differences in the incidence of other postoperative clinical end points were observed as a function of preoperative beta-blockers except in stroke (0.7% for the non-beta-blocker group vs. 0.3 for the beta-blocker group; adjusted OR 0.39 [95% CI 0.16–0.96]). Results of propensity-matched analyses were broadly consistent. Conclusions In this study, the administration of beta-blockers before CABG was not associated with improved operative mortality and complications except the incidence of postoperative stroke in patients with left ventricular dysfunction. A more granular quality metric which would guide the use of beta-blockers should be developed.

Background. Cocaine use is associated with multiple cardiovascular complications including heart failure. The use of different types of beta blockers in heart failure patients with active cocaine use is still a matter of debate. In this review, our objective is to systematically review the available literature regarding the use of beta blockers in the treatment of heart failure patients with concurrent cocaine use. Methods. PubMed, EMBASE, Web of Science, and Clinical Trials.gov were searched from inception to March 2019 using the Medical Subject Headings (MeSH) terms “cocaine”, “heart failure”, “beta blocker,” and “cardiomyopathy”. Only studies containing the outcomes of heart failure patients with active cocaine use who were treated with beta blockers were included. Results. The search resulted in 2072 articles out of which 12 were finally included in the review. A total number of participants were 1994 with a median sample size of 111. Most of the studies were retrospective in nature with Oxford Centre for Evidence-Based Medicine (OCEBM) Levels of Evidence from 3 to 5. The main primary outcomes included readmission rates, mortality, left ventricular ejection fraction (LVEF) improvement, New York Heart Association (NYHA) functional class, and major adverse cardiovascular events (MACEs). In the studies analyzed, beta blockers were found to have either a beneficial or a neutral effect on primary outcomes in heart failure patients with active cocaine use. Conclusion. The use of beta blocker therapy appears to be safe and beneficial in heart failure patients with active cocaine use, although the evidence is not robust. Furthermore, large-scale studies are required to confirm this finding.
