Abstract
Myocardial blood flow was measured respectively at intact, marginal and infarcted area which were determined by epicardial mapping ECG. Simultaneously the infarct size was estimated by epicardial ECG. Myocardial blood flow in marginal area was significantly increased with LVAD support (counter pulsation mode). Epicardial mapping ECG showed significant reduction in ST-elevation under LVAD assistance. These results suggest that LVAD treatment reduces infarct size by increasing blood flow in jeopardized area in AMI.
