Introduction: Despite its high prevalence and clinical significance, characterization of acute
heart failure (AHF) has not been fully addressed. Thus this study aimed to evaluate
prognostic impact of physiological parameters, systolic blood pressure (SBP) and heart
rate (HR), in AHF patients. Methods and Results: Consecutive 535 patients diagnosed as AHF were studied. Kaplan-Meier analysis when
participants were divided into four subgroups by with or without elevated SBP (>or
≤140 mmHg) and HR (>94 or ≤94 bpm) showed highest incidence of cardiovascular death
in patients with low systolic BP and low HR. Categorical hazard ratios by multivariate
Cox hazard analysis showed significantly high risk for cardiovascular death in the
subgroup having lower BP and HR. Conclusion: Low HR, in addition to low SBP predict high cardiovascular mortality in AHF.
