Fig. 3: Image phenotype associations with chronological age.
From: Environmental and genetic predictors of human cardiovascular ageing
In total, we measured 126 image-derived phenotypes, including temporal motion analysis of cine imaging. A selection of 15 representative phenotypes of volumes, function, and tissue characterisation are shown with their relationship to chronological age at the time of imaging. (n = 39,443, ages jittered, density contours, point colours represent coefficient of determination (R2)). LVEDV left ventricular end-diastolic volume, LVM left ventricular mass, LA max. vol left atrial maximum volume, RVEDV right ventricular end-diastolic volume, RA max. vol right atrial maximum volume, Asc/Dsc Ao max. ascending/descending aortic maximal cross-sectional area, Asc/Dsc Ao dist. ascending/descending aortic distensibility, RV/LVEF right/left ventricular ejection fraction, LAEF left atrial ejection fraction, PDSR peak diastolic strain rate, T1 longitudinal relaxation time of the tissue.
