Data are from the Atherosclerosis Risk in Communities (ARIC) study baseline examination (1987–89) in a subsample without prevalent HF and not missing information on important covariates, followed up to 31 December 2004.
Using spirometry, any COPD was defined as FEV1/FVC <70%, mild COPD was defined as FEV1/FVC <70% and FEV ≥80% (predicted), moderate/severe COPD was defined as FEV1/FVC <70% and FEV1 <80% (predicted), and no COPD as FEV1/FVC ≥70%.
CI, confidence interval; COPD, chronic obstructive pulmonary disease; FEV1, forced expiratory volume in 1 s; FVC, forced vital capacity; HR, hazard ratio.
aModel 1 is adjusted for age and race.
bModel 2 is adjusted for age, smoking status, cigarette-years of smoking, hypertension, diabetes, LDL-cholesterol, HDL-cholesterol, and body mass index.
cChronic bronchitis was defined as productive cough for at least 3 months in two contiguous years.
dSelf-reported diagnosis of COPD is the presence of self-reported diagnosis of either bronchitis or emphysema.
