ABSTRACT
To determine the incidence of early left ventricular infarct expansion within five days after first anterior ST-segment elevation myocardial infarction and the effect of early thrombolytic therapy on the incidence of early infarct expansion compared with late thrombolytic therapy. In a prospective study of 101 patients [75males and 26 females], with the first attack of acute anterior myocardial infarction, their ages ranged from 40-80 years [mean age 61.07 +/- 10.78] who had been admitted to the Coronary Care Unit of Hawler Teaching Hospital for the period from July 2007 through to September 2009. Those who received alteplase = 3 hours of acute myocardial infarction were labelled as group-I [49 patients] and those who received alteplase >3-12 hours were labelled as group-II [52 patients]. The incidence of early left ventricular infarct expansion was diagnosed by 2D-echocardiography and was found to be 17.8%. Group I patients had a lower incidence of early left ventricular infarct expansion [8.16%] compared with group-II [26.92%; p=0.014]. Patients with early left ventricular infarct expansion had a higher frequency rate of left ventricular systolic dysfunction [94.44%] compared to patients without early left ventricular infarct expansion [8.43%; p<0.001]. There was a significant difference in the incidence of in-hospital mortality between the patients who developed early left ventricular infarct expansion [11.1%] compared with patients without early left ventricular infarct expansion [1.2%; p=0.025]. Early reperfusion therapy in acute anterior myocardial infarction can decrease the incidence of early left ventricular infarct expansion, preserve left ventricular systolic function and decrease in-hospital mortality
