Outcomes in heart failure patients with preserved ejection fraction: mortality, readmission, and functional decline

Abstract

We evaluated the six-month clinical trajectory of patients hospitalized for heart failure (HF) with preserved ejection fraction (EF), as the natural history of this condition has not been well established. We compared mortality, hospital readmission, and changes in functional status in patients with preserved versus depressed EF. Although the poor prognosis of HF with depressed EF has been extensively documented, there are only limited and conflicting data concerning clinical outcomes for patients with preserved EF. We prospectively evaluated 413 patients hospitalized for HF to determine whether EF >or=40% was an independent predictor of mortality, readmission, and the combined outcome of functional decline or death. After six months, 13% of patients with preserved EF died, compared with 21% of patients with depressed EF (p = 0.02). However, the rates of functional decline were similar among those with preserved and depressed EF (30% vs. 23%, respectively; p = 0.14). After adjusting for demographic and clinical covariates, preserved EF was associated with a lower risk of death (hazard ratio [HR] 0.49, 95% confidence interval [CI] 0.26 to 0.90; p = 0.02), but there was no difference in the risk of readmission (HR 1.01, 95% CI 0....Continue Reading
