Values are median (IQR) where absolute skew is ≥0.9, n (%), or mean ± SD. The data shown here are from the subjects with values that were available. Bold indicates differences between the 2 groups are statistically significant (P < 0.05).
BMI = body mass index; CMR = cardiac magnetic resonance; LVEDVI = left ventricular end-diastolic volume index; LVEF = left ventricular ejection fraction; LVESVI = left ventricular end-systolic volume index; LVGFI = left ventricle global function index; LVMI = left ventricular mass index; LVSVI = left ventricular stroke volume index; M/V = LV mass-to-volume ratio; RVEDVI = right ventricular end-diastolic volume index; RVESVI = right ventricular end-systolic volume index; RVSVI = right ventricular stroke volume index; TAC = total arterial compliance; other abbreviation as in Table 1.
