  abstract  = {Prospective longitudinal follow-up of left ventricular ejection fraction (LVEF) trajectories after acute cardiac decompensation of heart failure is lacking. We investigated changes in LVEF and covariates at 6-months' follow-up in patients with a predischarge LVEF ≤40\%, and determined predictors and prognostic implications of LVEF changes through 18-months' follow-up. Methods and Results Interdisciplinary Network Heart Failure program participants (n=633) were categorized into subgroups based on LVEF at 6-months' follow-up: normalized LVEF (>50\%; heart failure with normalized ejection fraction, n=147); midrange LVEF (41\%-50\%; heart failure with midrange ejection fraction, n=195), or persistently reduced LVEF (≤40\%; heart failure with persistently reduced LVEF , n=291). All received guideline-directed medical therapies. At 6-months' follow-up, compared with patients with heart failure with persistently reduced LVEF, heart failure with normalized LVEF or heart failure with midrange LVEF subgroups showed greater reductions in LV end-diastolic/end-systolic diameters (both P<0.001), and left atrial systolic diameter (P=0.002), more increased septal/posterior end-diastolic wall-thickness (both P<0.001), and significantly greater improvement in diastolic function, biomarkers, symptoms, and health status. Heart failure duration <1 year, female sex, higher predischarge blood pressure, and baseline LVEF were independent predictors of LVEF improvement. Mortality and event-free survival rates were lower in patients with heart failure with normalized LVEF (P=0.002). Overall, LVEF increased further at 18-months' follow-up (P<0.001), while LV end-diastolic diameter decreased (P=0.048). However, LVEF worsened (P=0.002) and LV end-diastolic diameter increased (P=0.047) in patients with heart failure with normalized LVEF hospitalized between 6-months' follow-up and 18-months' follow-up. Conclusions Six-month survivors of acute cardiac decompensation for systolic heart failure showed variable LVEF trajectories, with >50\% showing improvements by ≥1 LVEF category. LVEF changes correlated with various parameters, suggesting multilevel reverse remodeling, were predictable from several baseline characteristics, and were associated with clinical outcomes at 18-months' follow-up. Repeat hospitalizations were associated with attenuation of reverse remodeling."},

  abstract  = {Aims This study investigated, whether an activated R-mode, a surrogate of chronotropic incompetence in patients carrying a cardiovascular implantable electronic device (CIED), is associated with worse prognosis during and after an episode of acutely decompensated heart failure (AHF). Methods and Results Six hundred and twenty-three patients participating in an ongoing prospective cohort study that phenotypes and follows patients admitted for AHF were studied. We compared CIED carriers with R-mode stimulation (n=37) to CIED carriers not in R-mode (n=64) and patients without CIEDs (n=511). Mean heart rate on admission was significantly lower in R-mode patients vs. patients with CIED but without R-mode or patients withour CIED. In-hospital mortality was similar across groups, but age- and sex-adjusted 12-month mortality risk was higher in R-mode group. These effects persisted after multivariable adjustment for comorbidity burden. Conclusion In patients admitted for AHF, R-mode stimulation was associated with a significantly increased 12-month mortality risk. Our findings suggest that chronotropic incompetence per se mediates an adverse outcome and may not be adequately treated through accelerometer-based R-mode stimulation during and after an episode of AHF.},

  abstract  = {Aims It has been hypothesized that cardiac decompensation accompanying acute heart failure (AHF) episodes generates a pro-inflammatory environment boosting an adaptive immune response against myocardial antigens, thus contributing to progression of heart failure (HF) and poor prognosis. We assessed the prevalence of anti-myocardial autoantibodies (AMyA) as biomarkers reflecting adaptive immune responses in patients admitted to the hospital for AHF, followed the change in AMyA titres for 6 months after discharge, and evaluated their prognostic utility. Methods and results AMyA were determined in n = 47 patients, median age 71 (quartiles 60; 80) years, 23 (49\%) female, and 24 (51\%) with HF with preserved ejection fraction, from blood collected at baseline (time point of hospitalization) and at 6 month follow-up (visit F6). Patients were followed for 18 months (visit F18). The prevalence of AMyA increased from baseline (n = 21, 45\%) to F6 (n = 36, 77\%; P < 0.001). At F6, the prevalence of AMyA was higher in patients with HF with preserved ejection fraction (n = 21, 88\%) compared with patients with reduced ejection fraction (n = 14, 61\%; P = 0.036). During the subsequent 12 months after F6, that is up to F18, patients with newly developed AMyA at F6 had a higher risk for the combined endpoint of death or rehospitalization for HF (hazard ratio 4.79, 95\% confidence interval 1.13-20.21; P = 0.033) compared with patients with persistent or without AMyA at F6. Conclusions Our results support the hypothesis that AHF may induce patterns of adaptive immune responses. More studies in larger populations and well-defined patient subgroups are needed to further clarify the role of the adaptive immune system in HF progression.},
