Abstract

An expanding number of therapies are now indicated for comorbidity management in heart failure with preserved ejection fraction (HFpEF). Whether comorbidity burdens differ for patients with HFpEF who are hospitalized for acute decompensated heart failure (ADHF) versus those with chronic stable heart failure (CSHF) who are hospitalized for other causes is uncertain. Since 2005, the Atherosclerosis Risk in Communities (ARIC) study has conducted adjudicated community surveillance of hospitalized heart failure. Hospitalized ADHF and CSHF were sampled identically, using prespecified discharge codes and demographic strata, but were differentiated by signs or symptoms of acute or worsening heart failure upon physician review of the medical record. HFpEF was defined by an ejection fraction ≥50%. All events were weighted by the inverse of the sampling probability for statistical analyses. From 2005 to 2014, 13,706 weighted (2,936 unweighted) hospitalizations (mean age 77 years, 64% women, 29% Black) were sampled among patients with HFpEF and adjudicated ADHF (86%) or CSHF (14%). Comorbidity prevalence was high both for ADHF and CSHF hospitalizations, irrespective of gender. Women hospitalized with ADHF versus CSHF had greater prevalence of hypertension (89% vs 84%) diabetes mellitus (48% vs 39%) and renal disease (85% vs 74%). Echocardiographic features such as left ventricular hypertrophy and valvular abnormalities were more common with ADHF than CSHF, for both genders. However, the 28-day and 1-year mortality risk were comparable for ADHF and CSHF. In conclusion, hospitalized patients with HFpEF have a high comorbidity burden and risk of death, irrespective of the cause of hospitalization.
