Fig. 1: Summary of data used for cardiovascular age prediction in UK Biobank.
From: Environmental and genetic predictors of human cardiovascular ageing
a Age distributions of participants by sex (kernel density estimates, 20,502 females, and 18,947 males). b Phenotypes used for prediction. The top row shows cardiac magnetic resonance images with automated time-resolved segmentation of the aorta and cardiac chambers. The bottom row shows an example of left ventricular motion analysis to derive radial strain rate and a parametric T1 map of the left ventricular myocardium. Resting electrocardiograms (ECGs) were used in an independent model for age prediction. LA left atrium, LV left ventricle, RA right atrium, RV right ventricle, Asc Ao ascending aorta, Dsc Ao descending aorta. c The relationship between predicted and chronological cardiovascular age (n = 34,137, ages jittered, density contours, and a marginal density plot.).
