- LVDD = left ventricular diastolic diameter, LVDS = left ventricular systolic diameter, LVEDV = left ventricular end-diastolic volume, LVESV = left ventricular end-systolic volume, LVSV = left ventricular stroke volume, LVEF = left ventricular ejection fraction, MI = myocardial infarction, NYHA = New York Heart Association, LGE late gadolinium enhancement
- * Percent of segments = number of segment with feature divided by total analyzable segments
- **wall thinning = EDWT < 5.5 mm
