Incidence Of Rehospitalization For Heart Failure Research Articles

What underlies sex differences in heart failure onset within the first year after a first myocardial infarction?

Women are more likely to develop heart failure (HF) after myocardial infarction. However, diagnosis and reperfusion are often delayed. To compare the prevalence of HF after primary percutaneous coronary intervention (PPCI)-treated ST segment myocardial infarction (STEMI) between sexes and to study its associations with comorbidities, infarct size, and left ventricular (LV) systolic and diastolic dysfunctions (DD). The patients with PPCI-treated anterior STEMI, from the CIRCUS study cohort, were followed up for 1 year and HF events were recorded. Evaluation of ejection fraction (LVEF) and DD were performed at baseline and at 1 year. The elevated LV filling pressure (LVFP) included Grades 2 and 3 DD. Of the 791 patients from the CIRCUS study, 135 were women. At 1 year, the proportion of patients who developed HF was 21% among men and 34% among women (p = 0.001). In the subset of 407 patients with available diastolic parameters, the rate of HF was also higher in women. HF during the initial hospitalization was comparable between the sexes. However, women had a higher incidence of rehospitalization for HF within the first year after STEMI (14.1% vs. 4.1%, p = 0.005). Women were older with a higher prevalence of hypertension. The infarct size and LVEF were similar between the sexes. Elevated LVFP was observed more frequently in women than in men during the initial hospitalization and at 1 year (26% vs. 12%, p = 0.04, and 22% vs. 12%, p = 0.006, respectively). Interestingly, only initial elevated LVFP (HR 5.9, 95% CI: 2.4-14.5, p < 0.001), age, and hypertension were independently associated with rehospitalization for HF. After PPCI-treated anterior STEMI, despite comparable infarct size and LVEF, women presented a higher proportion of rehospitalization for HF than men. That was likely due to a greater DD associated with older age and hypertension.

Dapagliflozin reduces risk of heart failure rehospitalization in diabetic acute myocardial infarction patients: a propensity score-matched analysis

ObjectiveThe aim of this study was to investigate the effect of dapagliflozin (DAPA) on the rate of heart failure rehospitalization in patients with acute myocardial infarction (AMI) and type 2 diabetes mellitus (T2DM).MethodsAMI patients with T2DM from CZ-AMI registry between January 2017 and January 2021 were enrolled in this study. Patients were stratified into DAPA users and non-DAPA users. The primary outcome was the incidence of heart failure rehospitalization. Kaplan–Meier analysis and Cox regressions were performed to evaluate the prognostic significance of DAPA. Propensity score matching (PSM) was performed to minimize the bias of confounding factors and facilitate the comparability between groups. The enrolled patients were matched with a propensity score of 1:1.ResultsA total of 961 patients were included, and 132 (13.74%) heart failure rehospitalizations occurred during a median follow-up of 540 days. In the Kaplan–Meier analysis, DAPA users had a statistically significantly lower rate of heart failure rehospitalization than non-DAPA users (p < 0.0001). Multivariate Cox analysis showed that DAPA was an independent protective factor for heart failure rehospitalization risk after discharge (HR = 0.498, 95% CI = 0.296 ~ 0.831, p = 0.001). After 1:1 propensity score matching, survival analysis showed a lower cumulative risk of heart failure rehospitalization in DAPA users than in non-DAPA users (p = 0.0007). In-hospital and continued use of DAPA remained significantly associated with a reduced risk of heart failure rehospitalization (HR = 0.417, 95% CI = 0.417 ~ 0.838, p = 0.001). Results were consistent across sensitivity and subgroup analyses.ConclusionIn patients with diabetic AMI, in-hospital and continued use of DAPA after discharge were associated with a significant lower risk of heart failure rehospitalization.

Update on the clinical impact of mild aortic regurgitation after transcatheter aortic valve implantation: Insights from the Japanese multicenter OCEAN‐TAVI registry

This study aimed to compare the clinical impact of mild postprocedural aortic regurgitation (post-AR) to that of none-trivial post-AR after transcatheter aortic valve implantation (TAVI) and to identify the vulnerability factors to mild post-AR. Moderate-severe post-AR, associated with increased mortality, is an important issue. However, the clinical impact of mild post-AR remains controversial. We analyzed data from 1,572 consecutive patients (1,026 of none-trivial post-AR and 546 of mild post-AR) obtained from the Optimized transCathEter vAlvular Intervention (OCEAN-TAVI) Japanese multicenter registry. We evaluated the 1-year cumulative cardiovascular death and re-hospitalization rates for heart failure (HF) after TAVI according to the degree of post-AR. Kaplan-Meier curves showed no significant difference between "none-trivial post-AR" and "mild post-AR" in terms of cardiovascular death, but a significant difference was noted in the cumulative incidence of re-hospitalization for HF between the two groups (hazard ratio 1.57, 95% confidence interval 1.02-2.41, p = .04). In the stratified analysis, only in patients with not more than 50% of left ventricular ejection fraction (LVEF), concentric left ventricular hypertrophy (LVH), and none-trivial pre-procedural aortic regurgitation (pre-AR), mild post-AR resulted in a higher incidence of re-hospitalization for HF. In this study, the clinical impact of mild post-AR compared to none-trivial post-AR tended to be augmented in the presence of reduced LVEF, concentric LVH, and none-trivial pre-AR. Pre-procedure echocardiographic findings including LVEF, left ventricular geometry, and pre-AR may help to judge the necessity of postdilatation in case of mild post-AR just after the bioprosthesis deployment.

Timing of Susceptibility to Mortality and Heart Failure in Patients With Preexisting Atrial Fibrillation After Transcatheter Aortic Valve Implantation

The relationship between cardiac rhythm and adverse events after transcatheter aortic valve implantation (TAVI) remains unclear. To compare the prognostic impact of preexisting atrial fibrillation (AF) and new-onset AF (NOAF) after TAVI, we assessed 1,124 patients (846 with sinus rhythm [SR], 49 with NOAF, and 229 with preexisting AF) who underwent TAVI with a balloon-expandable valve from October 2013 to April 2016. The incidences of all-cause death and rehospitalization for heart failure (HF) were retrospectively evaluated. The median follow-up period was 370 days (range 188 to 613). In the Kaplan-Meier analysis, the incidences of all-cause death and rehospitalization for HF were significantly higher in patients with preexisting AF than those in patients with NOAF and SR. The multivariable analysis showed that preexisting AF was significantly associated with increased all-cause death (hazard ratio [HR] 1.54; 95% confidence interval [CI] 1.02 to 2.34) and rehospitalization for HF (HR 2.94; 95% CI 1.75 to 4.93). The landmark analysis demonstrated that patients with preexisting AF had a significantly higher incidence of rehospitalization for HF within the first 6 months after TAVI (HR 4.04; 95% CI 2.23 to 7.32), and a higher incidence of all-cause death from 6 months to 2 years after TAVI (HR 2.12; 95% CI 1.15 to 3.90). Our study demonstrated that preexisting AF increased the risk of all-cause death and rehospitalization for HF after TAVI in comparison with NOAF or SR. Moreover, there was a specific timing of susceptibility to all-cause death and rehospitalization for HF after TAVI.

Rola krążącego receptora dla IL-33 (sST2) w monitorowaniu terapii niewydolności serca

Heart failure (HF) is currently one of the major health problems in Poland and in other European countries. Despite the progress that has been made in the treatment of HF, mortality and the incidence of re-hospitalization for HF are still very high. One of the reasons is the lack of proper heart failure treatment optimization. Among the currently studied new biomarkers of heart failure, one of the special interest is circulating receptor for IL-33 (sST2). It has been shown that IL-33 plays cardioprotective role. Its molecular mechanisms of action are based mainly on the activation of the transmembrane form of ST2 receptor (ST2L). Availability of IL-33 for ST2L is limited by binding to the soluble fraction of the ST2 (sST2) — called a „decoy receptor”. The presence of elevated levels of sST2 in the population of patients with heart failure is associated with more severe left ventricular remodeling, impaired diastolic function and right ventricle function. Patients with both HF and high and/or rising levels sST2 are at high risk of adverse cardiovascular events. The standard treatment for heart failure leads to reduction in sST2 concentration. Among the drugs used in the heart failure treatment, two with the largest impact on reducing concentration of sST2 are beta-blockers in high doses, and aldosterone.
