Short-term outcomes in heart failure patients with chronic obstructive pulmonary disease in the community.

AIM

To establish the short term outcomes of heart failure (HF) patients in the community who have concurrent chronic obstructive pulmonary disease (COPD).

METHODS

We evaluated 783 patients (27.2%) with left ventricular systolic dysfunction under the care of a regional nurse-led community HF team between June 2007 and June 2010 through a database analysis.

RESULTS

One hundred and one patients (12.9%) also had a diagnosis of COPD; 94% of patients were treated with loop diuretics, 83% with angiotensin converting enzyme inhibitors, 74% with β-blockers; 10.6% with bronchodilators; and 42% with aldosterone antagonists. The mean age of the patients was 77.9 ± 5.7 years; 43% were female and mean New York Heart Association class was 2.3 ± 0.6. The mean follow-up was 28.2 ± 2.9 mo. β-blocker utilization was markedly lower in patients receiving bronchodilators compared with those not taking bronchodilators (overall 21.7% vs 81%, P < 0.001). The 24-mo survival was 93% in patients with HF alone and 89% in those with both comorbidities (P = not significant). The presence of COPD was associated with increased risk of HF hospitalization [hazard ratio (HR): 1.56; 95% CI: 1.4-2.1; P < 0.001] and major adverse cardiovascular events (HR: 1.23; 95% CI: 1.03-1.75; P < 0.001).

CONCLUSION

COPD is a common comorbidity in ambulatory HF patients in the community and is a powerful predictor of worsening HF. It does not however appear to affect short-term mortality in ambulatory HF patients.
