Abstract

Aims Little is known about the characteristics and outcomes of patients who undergo coronary angiography during heart failure (HF) hospitalization, as well as those with coronary stenosis, and those who underwent coronary revascularization. Methods and results We analysed 2163 patients who were hospitalized for HF without acute coronary syndrome or prior HF hospitalization. We compared patient characteristics and 1 year clinical outcomes according to (i) patients with versus without coronary angiography, (ii) patients with versus without coronary stenosis, and (iii) patients with versus without coronary revascularization. The primary outcome measure was the composite of all‐cause death or HF hospitalization. Coronary angiography was performed in 37.0% of patients. In the multivariable logistic regression analysis, factors independently associated with coronary angiography were age

Abstract

[Background]: There is a scarcity of reports on the clinical characteristics and management practice in contemporary all-comer patients with acute decompensated heart failure (ADHF). [Methods and Results]: The Kyoto Congestive Heart Failure (KCHF) registry is a prospective observational cohort study enrolling 4, 056 consecutive patients who had hospital admission due to ADHF without any exclusion criteria between October 2014 and March 2016 in the 19 participating hospitals in Japan. Baseline characteristics, clinical presentations, management, and in-hospital outcomes were compared between heart failure (HF) with reduced left ventricular ejection fraction (LVEF; HFrEF, LVEF

Abstract

Abstract Aims Although the prognostic impact of the high tricuspid regurgitation pressure gradient (TRPG) has been investigated, the association of the decrease in TRPG during follow‐up with clinical outcomes in heart failure (HF) has not been previously studied. The aim of this study was to investigate the association of a decrease in TRPG between hospitalization and 6 month visit with subsequent clinical outcomes in patients with acute decompensated HF (ADHF). Methods and results Among 721 patients with available TRPG data both during hospitalization and a subsequent 6 month visit, the study population was divided into two groups: a decrease in TRPG group (>10 mmHg decrease at 6 month visit) (N = 179) and no decrease in TRPG group (N = 542). The primary outcome measure was a composite of all‐cause death or HF hospitalization. The cumulative 6 month incidence of primary outcome measure was significantly lower in the decrease in TRPG group than in the no decrease in TRPG group (12.2% vs. 18.7%, P = 0.02). After adjusting for confounders, there was a significantly lower risk in decrease in TRPG group than in the no decrease in TRPG group for the measured primary outcome (hazard ratio: 0.56, 95% confidence interval 0.32–0.93, P = 0.02). The lower risk in decrease in TRPG group was not different among the basal TRPG values. Conclusions Heart failure patients with a decrease in TRPG at 6 months after discharge from ADHF hospitalization had lower subsequent risk of all‐cause death and HF hospitalization than those without a decrease in TRPG, regardless of TRPG values.
