Objective: The aim of this study was to describe the clinical characteristics of patients that have had a heart failure with preserved ejection fraction (HF-pEF) and to identify the factors associated with 5-year mortality and readmission. Methods: A prospective cohort study was conducted of patients followed by the Heart Failure Unit of the Internal Medicine Department. Clinical characteristics and outcomes were collected. Univariate and multivariate analyses were performed in order to

The main etiology was hypertensive heart disease and a high level of comorbidity (chronic renal failure, hypertension and atrial fibrillation) was observed. The 5-year mortality was 55.5%; the related variables were anemia (hazard ratio [HR]=1.7; 95% confidence interval [CI]: 1.2-2.5), in patients being treated with statins (HR=0.7; 95%CI 0.5-0.9) and spironolactone (HR= 1.6; 95% CI: 1.1-2.3); 24.5% of patients had >2 admission in 5 years, with the main related factors being atrial fibrillation (HR=2.7; 95%CI: 1.4-5.5), anemia (HR=1.9; 95%CI:1.0-3.3) and were being treated with spironolactone (HR=2.1; 95%CI:1.2-3.7). Conclusion: Patients with HF-pEF are old and present a high level of comorbidity. Furthermore, they have a high 5-year mortality and readmission rate. The only factor associated with lower mortality was the treatment with statins. The use of spironolactone was associated with a higher mortality risk.
