LATE-BREAKING ABSTRACT: Risk factors for hospitalization and death in elderly smokers with chronic obstructive pulmonary disease (COPD) and/or chronic heart failure (CHF)
Aim: We examined 2 groups of elderly (≥65yrs) smokers (≥20p/y) with primary diagnosis of COPD and/or CHF to investigate prospectively the risk factors for hospitalization and death due to cardiopulmonary events over 3 yrs. Methods: In 144 COPD pts (68-77 yrs;male 76%) and 96 CHF pts (71-78 yrs;male 91%), we assessed age-adjusted Charlson Index (CCI), COPD Assessment Test (CAT), modified Medical Research Council (mMRC) dyspnea scale, spirometry, and echocardiography. Results: COPD pts were in GOLD classes I(32), II(79), III(30), IV(3), whereas CHF in NYHA classes I(40), II(49), III(6), missing in 1 patient. Among CHF pts, 26% had airflow limitation (mostly with moderate obstructive ventilatory pattern). The prevalence of CHF in COPD pts was 5% (mainly NYHA class I). CCI score was greater in CHF as compared to COPD pts (p Conclusions: Older age, comorbidities and dyspnea are major risk factors for hospitalization and death due to cardiopulmonary causes in smokers with COPD and/or CHF. Lower lung function predicts only the future risk of hospital admission in these patients. Funded by Ministry of Health, CFR, Chiesi Foundation
