Abstract
Background: The purpose of this study was to report the prevalence, clinical characteristics, contributing factors, management and outcome of patients with chronic obstructive pulmonary disease (COPD) among patients hospitalized with heart failure (HF). Methods: Data were derived from Gulf Care (Gulf acute heart failure registry), a prospective multicenter study of 5005 consecutive patients hospitalized with acute heart failure during February to November 2012 in seven Middle Eastern countries. Data were described and compared for demographics, management and outcomes. Results: The prevalence of COPD among HF patients was 10%. COPD patients were older, more likely to be female and to have diabetes, hypertension, chronic kidney disease and sleep apnea (P = 0.001 for all) when compared to non-COPD patients. Contributing factors for hospitalization were systemic infection and atrial arrhythmias in COPD patients compared to acute coronary syndrome, uncontrolled hypertension and anemia in the non-COPD patients. Left-ventricular ejection fraction was higher in COPD patients; while BNP levels were comparable between the two groups. Non-invasive ventilation was used more frequently among COPD patients compared to non-COPD patients (P = 0.001). On multivariate logistic regression analysis, COPD was not associated with increased risk in-hospital and one-year death among acute heart failure (AHF) population and β blockers treatment appear to have neutral mortality effect in COPD patients with HF. Conclusion: COPD have distinct cardiovascular risk profile and precipitating factors for hospitalization with HF when compared to non-COPD patients. COPD history had no impact on the short-term and one-year mortality.
