Abstract
INTRODUCTION: Heart failure is a major cause of death and disability and poses a significant public health concern. Approximately half of the patients admitted with heart failure, have preserved left ventricular ejection fraction. The association between systolic blood pressure (SBP) and long-term outcome in this group has not been well established. AIM: The aim of our study is to evaluate the association between admission SBP and short term and long-term mortality outcomes in patients with heart failure and preserved systolic function. METHODS: 1230 consecutive patients presenting with preserved left ventricular (LV) systolic function (defined as an LV ejection fraction ≥40%) were included in this survey. Patients were divided into quartiles according to admission SBP: low admission SBP (<127mmHg), intermediate admission SBP (128-145mmHg), high admission SBP (146-170mmHg) and very-high admission SBP (>170mmHg). Primary outcome included in hospital, one and four year mortality rates. RESULTS: Elevated admission SBP was found to be associated with improved short and long-term mortality (HR=0.25 95% CI - 0.09-0.7, p=0.007 and HR=0.7 95% CI - 0.56-0.88, p=0.002 for the highest versus low SBP group, respectively). This finding was most notable in patients with acute heart failure and patients with ejection fraction≥50%. CONCLUSION: Elevated admission SBP is associated with a favorable short and long-term outcome in patients with heart failure and preserved systolic function. KEY MESSAGE: Low admission SBP is an independent predictor for short and long-term mortality in patients with HF and PSF.
