Shown are mean and SD or proportions.
E/e’: ratio of the transmitral early peak velocity by pulsed wave Doppler over mean early diastolic velocity determined at the septal and lateral mitral annulus by tissue Doppler. Diastolic dysfunction determined according to ref 23.
BP, blood pressure; BSA, body surface area; eGFRcrea, glomerular filtration rate estimated from serum creatinine; hsTnT, high-sensitivity cardiac troponin T; LVMi, ratio of left ventricular mass to body surface area; NT-proBNP, N-terminal prohormone B-type (brain) natriuretic peptide.
