Abstract
Background:We investigated the relationship between admission systolic blood pressure (SBP) and all-cause mortality in patients hospitalized for acute decompensated heart failure (ADHF) because of aortic stenosis (AS).Methods and Results:We retrospectively reviewed the data for 71 consecutive patients (mean age 85±7 years) who had been hospitalized for ADHF because of AS between January 2006 and August 2012. The primary endpoint of the study was the 1-year all-cause mortality. Clinical outcomes of patients who survived and those who died during a 1-year period were compared. Low admission SBP was defined as <120 mmHg. During the 1-year period, 26 (37%) of the 71 patients died, including 16 (57%) of 28 patients with low SBP and 10 (23%) of 43 patients with normal or high SBP (log-rank P=0.0065). In both the patients who survived and those who died, there were significant differences in admission SBP (152±43 vs. 116±32 mmHg, P<0.001), estimated glomerular filtration rate on admission (43.2±20.3 vs. 28.2±22.2 ml·min(-1)·1.73 m(-2), P=0.005), and left ventricular ejection fraction <50% (33% [15/45] vs. 65% [17/26], P=0.013). Low admission SBP independently predicted 1-year all-cause mortality (adjusted hazard ratio: 2.41, 95% confidence interval: 1.04-5.57, P=0.033).Conclusions:Low admission SBP is associated with significantly higher 1-year all-cause mortality in patients hospitalized for ADHF because of AS.
