Characteristics, Treatment, and Prognosis of Heart Failure Patients with Chronic Obstructive Pulmonary Disease in the Colombian Heart Failure Registry (RECOLFACA)

The impact of chronic obstructive pulmonary disease (COPD) on heart failure (HF) has yet to be well assessed in the Latin American population. This study aimed to analyze the impact of COPD on HF patients from the Colombian Heart Failure Registry (RECOLFACA). The primary outcome was all-cause mortality. A Cox proportional-hazards regression model was used to assess the impact of COPD on mortality. From the total of 2528 patients in the registry, 2514 patients had information regarding COPD diagnosis. COPD diagnosis was associated with a worse functional class and higher use of diuretics than non-COPD patients ( < 0.001). Patients with this comorbidity had a significantly better ejection fraction (median ejection fraction 35% vs. 32% in non-COPD patients; = 0.004), with a higher occurrence of HF with preserved ejection fraction (HFpEF) in the COPD group ( = 0.000). Finally, patients with COPD had a significantly higher risk of mortality in the multivariate regression model (HR 1.47; 95% CI 1.02, 2.11). COPD is a prevalent comorbidity among patients with HF in Colombia, showing a different clinical profile and a worse functional class than patients without this condition. Patients with COPD and HFpEF have a high mortality risk according to our results.
