LV Left ventricular; RV right ventricular; EF ejection fraction; SV stroke volume; EDV end-diastolic volume; ESV end-systolic volume; LA left atrium; Min minimum; Max maximum. Normal reference ranges are defined as the 95% prediction interval
Study cohort—excluded subjects with history of CVD or with risk factors of CVD -hypertension, diabetes, obesity, smoking or dyslipidemia
History of CVD—Aortic stenosis, Atrial fibrillation, Heart failure, Mitral stenosis, Previous PCI, Previous CABG, Valve surgery, TAVI, Hx of myocardial infarction
Reference ranges were calculated based on the formulae mean ± t0.975,n−1*sqrt[(n + 1)/n]*SD
*CI calculated based on the SE
