Echocardiography in Acute Myocardial Infarction. Remodeling of left ventricle and diastolic dysfunction

      Аннотация: Acute myocardial infarction (AIM) resulting change in the size and shape of left ventricle (LV). Aim- to determine whether parameters of echocardiography are important in AIM in predicting LV remodeling and in prediction of adverse cardiovascular events after AMI. Methods- The study included 70 patients with AMI. Patients were examined the clinical, laboratory and ECHO (dwo-dimensional, pulsed and tissue doppler) and angiographic and reviewed after 30 days. The outcomes were: death, reinfarction, or heart failure ((HF). Results- ECHO findings showed reduced systolic and diastolic LV function in the first 24 hours of AMI, while the E/Ea manifest high values > 9, After 30 days volumes increase in enddiastole and endsystole 18,6% patients had an ejection fraction (EF) <0.40, but 54.3% had E/Ea> 8 After 30 days 2D ECHO demonstrated that the HF significantly higher in patients with an increased dimensions and volume LV , an enlarged left atrium, mitral regurgitation and low EF, higher E wave and lower septal S Conclusion- ECHO parameters have prognostic significance in predicting recovery of LV after early reperfusion therapy and in predicting adverse events.
