Abstract
ST- elevation myocardial infarction is by far the most serious presentation of ACAD carrying the most hazardous consequences& patients with ST elevation are triaged immediately for reperfusion therapy. It is known that the T- wave reflects the myocardial repolarization, and changes in the T-wave configuration are among the first to indicate an AMI. Data on the value of T-wave changes in the setting of primary PCI are limited. The aim of our study was to study the significance of T-wave changes in patients with acute ST-Segment elevation myocardial infarction treated with primary percutaneous coronary intervention. It was found that changes in T- wave amplitude are positively correlated with higher blush grades post procedure; and that biphasic T- wave post procedure was associated with less successful reperfusion. It also showed that Tpeak-Tend interval decreased significantly post procedure, and that this reduction is significantly correlated with successful reperfusion. Further studies are still needed to further understand value of different ECG parameters in the light of new therapeutic modalities.
