Abstract

Ejection fraction (EF) is often unknown in patients who present with acute decompensated heart failure (ADHF). The objective of this study was to determine whether a patient's systolic blood pressure is associated with their left ventricular EF. This study was a retrospective chart review of all patients admitted to an emergency department (ED) observation unit from January 2002 to December 2004. A low EF was defined as <40%. Among 475 patients, the median age was 72years, 53% were men, 40% were white, 59% were black, and 59% had a low EF. Patients with low EFs were more likely male (P<.0001), with prior congestive heart disease (P<.0001), longer QRS duration (P<.0001), left bundle branch block (P<.0001), and higher B-type natriuretic peptide (P<.0001). The low EF group was less likely to have diabetes (P<.0001). Adjusted odds ratios for an EF ≥40% were significant at all systolic blood pressure readings >120 mm Hg. Having an ED systolic BP >120 mm Hg is associated with significantly higher rates of preserved left ventricular systolic function in patients with ADHF.
