BMI indicates body mass index; FEV1, forced expiratory volume in 1 second; LV, left ventricular; NT-proBNP, N-terminal pro-B-type natriuretic peptide; SD, standard deviation. Data were missing in 2% or fewer of participants for all characteristics except diabetes (missing in 27 whites and 34 blacks), fasting glucose (29 and 47), NT-proBNP (1131 and 195), cystatin C (607 and 67), left ventricular wall thickness (1682 and 342), and left atrial dimension (181 and 199).

*

FEV1 was ascertained at baseline in the original cohort, and after one year of follow-up in the black cohort. Echocardiography was performed at baseline in the original cohort and after two years of follow-up in the black cohort.

Among those with ≥1 drink/week.
