Shown are baseline characteristics of individuals who underwent tagged MRI at baseline and with information on conventional risk factors. For continuous variables, mean ± SD are given and for categorical variables, % are given.

SRI: strain relaxation index; EDSR: early diastolic strain rate; BNP: brain natriuretic peptide.
