Values are expressed as mean ± SD or N (%). BNP, N-terminal pro-brain natriuretic peptide; CAD, coronary artery disease; DBP, diastolic blood pressure; EDV, end diastolic volume; GLS, global longitudinal strain; LVMIht2.7, left ventricular mass indexed to Ht2.7; PWV, pulse wave velocity; QTc, QTc Fridericia; SBP, systolic blood pressure; TCRT, total cosine of R to T (in degrees). Statistically significant differences are highlighted with shaded areas.
