Background: The feasibility of spironolactone withdrawal in dilated cardiomyopathy patients with improved ejection fraction remains unknown. This study sought to determine whether spironolactone can be withdrawn safely in this circumstance.Methods: Consecutive patients with idiopathic dilated cardiomyopathy and prescribed spironolactone at discharge were included in this prospective, observational cohort using the Risk Evaluation and Management in Heart Failure Trial (NCT02998788) database. Those patients who experienced an absolute left ventricular ejection fraction (LVEF) improvement ≥10% and a second measurement of LVEF >40% would choose whether to continue spironolactone therapy and be included in final analysis. The primary endpoint was dilated cardiomyopathy relapse within 12 months, defined as a more than 10% reduction in LVEF, a 15% or greater increase in LVESVi, a 2-fold rise in NT-proBNP, or clinical signs of heart failure.Results: Seventy patients achieved an ejection fraction improvement and were included in the final analysis, of whom 30 chose to continue spironolactone and 40 decided to withdraw. In primary endpoint analysis, 23 (58%) patients from the withdrawal group and 4 (13%) patients from the continuation group relapsed (relative risk for relapse: 4.31; 95% CI: 1.67–11.11; p < 0.001). Patients from the withdrawal group experienced more symptom aggravation than the continuation group. No secondary safety endpoint was recorded. Improvements in cardiac structure parameters were no longer observed after spironolactone withdrawal, while improvements persisted in continuation group.Conclusions: Most dilated cardiomyopathy patients with improved ejection fraction will relapse after spironolactone withdrawal. These results should be weighed before spironolactone withdrawal was attempted.

Adaptive Servo Ventilation

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.

Main funding source(s): University Medicine Munich University Medicine Greifswald Introduction The vascular cell adhesion molecule-1 (VCAM-1) is overexpressed in a number of different inflammatory processes on activated endothelium. This could be shown in both a mouse model for autoimmune myocarditis and in human heart tissue from patients with lymphocytic myocarditis. In addition to the tissue-bound one, a soluble isoform of VCAM-1 (s-VCAM-1) can also be detected in the blood. Higher levels have been associated with worse clinical outcome in chronic heart failure patients of different etiology and other patient groups. Purpose Since both inflammation and fibrosis are key processes involved in the pathogenesis of dilated cardiomyopathy (DCM) and hypokinetic non-dilated cardiomyopathy (HNDC), we aimed to investigate the prognostic value of s-VCAM-1 plasma levels for survival in a large cohort of DCM and HNDC patients. Methods The cohort comprised of patients with a primary diagnosis of DCM, defined as reduced left ventricular ejection fraction (LVEF &lt;45%), increased left ventricular enddiastolic diameter according to HENRY score (LVEDD &gt;117%) at time of diagnosis as well as HNDC, defined as a reduced left ventricular ejection fraction (LVEF &lt;45%) but no increased LVEDD according to HENRY score (LVEDD &lt; =117%). Exclusion criteria were primary valvular diseases (≥ second degree), acute myocarditis, cancer, chronic alcoholism, coronary artery disease with epicardial stenosis &gt;50%, peripheral artery occlusive disease, known auto-immune disease and heart failure of other origins. Levels of s-VCAM-1 were measured in human plasma using an enzyme-linked immunosorbent assay (R&D Systems, USA). A Cox proportional hazard model for the association between s-VCAM-1 and all-cause mortality was adjusted for age, sex, time since symptom-onset, LVEF, kidney function (eGFR-CKDEPI), CRP and NT-proBNP. Results A total of 334 DCM patients were included in this single-center cohort (78.4 % males) with a mean age of 54.0 years [interquartile range [IQR] 47.0, 63.2). On average time since symptom onset was 1.5 years (IQR 0.1, 1.1), LVEF 30.7 % (IQR 25, 37), LVEDD 67.1 mm (IQR 62, 72). During a median follow-up of 12.4 years (IQR 10.1, 13.9), a total of 118 (35.3 %) patients died. Multivariable-adjusted cox regression model revealed a significantly increased all-cause mortality risk with increasing levels of s-VCAM-1 (p for trend =0.039), (hazard ratio [HR] 1.00045 (Conf. Interval 1.00002, 1.00087) for VCAM increase of 1 ng/mL, for increase of 100 ng/ml HR 1.046 (Conf- interval 1.002, 1.091), for increase of 1000ng/ml HR 1.57 (Conf_interval 1.02-2.41) (Kaplan Meier survival estimates see Figure 1, median s-VCAM-1 = 664 ng/ml, IQR 515,874). Conclusions s-VCAM-1 predicts long-term survival in DCM patients independent of NT-pro-BNP and other risk determinants. Further research needs to evaluate whether this biomarker proves useful in monitoring and planning management of DCM and HNDC patients (e.g. more intensive management in high-risk patients).
