- Patients measured immediately after acute anterior myocardial infarction (baseline, n=22) and patients measured again four months later (follow-up, n=22) different studied parameters are listed: Left ventricular end-diastolic diameter (LVEDD), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left ventricular ejection fraction (LVEF), scar mass, mean circumferential shortening (csh) over all segments of the left ventricle at aortic valve closure (AVC), mean and SD of time to maximum csh (Tmax) over all segments, the circumferential uniformity ratio estimate (CURE). All values are indicated as mean ± SD.
