Elevated heart rate in combination with elevated blood pressure predicts lower cardiovascular mortality in acute decompensated heart failure

Abstract

140 mmHg at presentation) and a non-HT-ADHF group (SBP ≤ 140 mmHg). Median follow-up duration measured 253 days. Unadjusted Kaplan-Meier analysis demonstrated both a lower cardiovascular mortality rate in the HT-ADHF group and similar incidences of heart failure rehos-pitalization in both groups. Adjusted Cox hazard analysis showed an association of elevated SBP at presentation with significantly lower cardiovascular mortality, though no such association was observed with heart failure re-hospitalization. Moreover, elevated heart rate in combination with elevated SBP at presentation predicted a significantly lower risk of cardiovascular mortality (Hazard Ratio: 0.32, 95% CI: 0.14-0.77, P = 0.01). Also, significantly lower cardiovascular mortality was observed in this subtype, compared with other types of ADHF.
