Key result
Concurrent COPD was present in 30% (90% CI 24-37%) of elderly patients with stable heart failure and a smoking history, and its presence did not alter survival.
Cohort (n=118)
May support COPD screening in elderly HF patients with smoking history; leaves open prognostic impact in broader cohorts.
BACKGROUND AND OBJECTIVE: The coexistence of chronic obstructive pulmonary disease (COPD) and chronic heart failure (CHF) increases with age. The occurrence, prognosis and therapeutic implications of concurrent COPD in elderly patients with CHF were investigated. METHODS: One hundred and eighteen consecutive patients, ≥ 65 years old with ≥ 10 pack/years of smoking and with a verified diagnosis of CHF in stable condition, were enrolled. They were followed for a mean of 1029 (range 758-1064) days. All patients had spirometry and the diagnosis and classification of COPD were made according to Global Initiative for Chronic Obstructive Lung Disease guidelines. RESULTS: The mean occurrence of COPD was 30% (90% confidence interval: 24-37%). At baseline in patients with CHF and COPD, there was a shorter 6-min walk distance, lower arterial oxygen tension, glomerular filtration rate and higher N-terminal pro-B-type natriuretic peptide (all P < 0.05). The prescription of CHF therapies, including β-blockers, was similar in the two groups. After follow up, the presence of COPD in patients with CHF did not appear to influence survival. CONCLUSIONS: COPD is relatively frequent in elderly patients with CHF. COPD did not alter survival.

Boschetto et al. (2012) conducted a cohort in Stable heart failure (n=118). Chronic obstructive pulmonary disease (COPD) vs. No COPD was evaluated on Survival. Concurrent COPD was present in 30% (90% CI 24-37%) of elderly patients with stable heart failure and a smoking history, and its presence did not alter survival.
