The data are presented as the mean ± standard deviation or median with interquartile range. a, P<0.05 vs. controls and HTN group; b, P<0.05 vs. controls. CMR, cardiac magnetic resonance; HTN-HFpEF, hypertension with heart failure with preserved ejection fraction; HTN, hypertension; LVEF, left ventricular ejection fraction; CO, cardiac output; LVESV, left ventricular end-systolic volume; LVEDV, left ventricular end-diastolic volume; SV, stroke volume; e' velocity, early diastolic mitral annulus velocity; E/e', early diastolic mitral inflow velocity/early diastolic mitral annulus velocity.
