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.
