Abstract
Background: Chronic obstructive pulmonary disease (COPD) is prevalent in heart failure (HF) patients, yet these patients are poorly characterized. We aimed to describe the characteristics and outcomes of patients with systolic dysfunction and COPD in a contemporary HF randomized trial. Methods and Results: EVEREST investigated 4,133 patients hospitalized with worsening HF and an ejection fraction (EF) <40%. We analyzed the characteristics and outcomes (all-cause mortality and cardiovascular mortality/HF hospitalization) of patients according to baseline COPD status. COPD was present in 10% (n = 416) of patients. Patients with COPD had a higher prevalence of comorbidities and were less likely to receive a β-blocker, angiotensin-converting enzyme inhibitor, or aldosterone antagonist. On univariate analysis, COPD was associated with increased all-cause mortality (HR 1.41, 95% CI 1.18-1.67) and cardiovascular mortality/HF hospitalization (HR 1.29, 95% CI 1.11-1.49). After adjusting for potential confounders, the risk associated with COPD remained increased, but was not statistically significant. Conclusion: The presence of COPD in HF patients is associated with an increased burden of comorbidities, lower use of HF therapies, and a trend toward worse outcomes. These findings provide a starting point for prospective investigations of the treatment of HF comorbidities to reduce the high postdischarge event rates.
