The aim of this study was to define the prognostic value of echocardiographic measurements about left ventricular function in relation with one-year cardiac mortality in myocardial infarction patients. 63 patients were divided into two groups: 25 in fatal group and 38 non-fatal group. Differences in left ventricular function (EF%, E-IVS, FS%, ET...) were found in comparison between fatal patients and survivals. Left ventricular ejection fraction (EF%) decreased significantly in the fatal patients. Prognostic value of EF% in relation with one-year cardiac mortality is Sensitivity: 64%, specificity: 84%, positive prognostic value: 72%, negative prognostic value 78%, under ROC area: 0.84. Special EF%  40% risk mortality increased 3.84 time. Global left ventricular systolic function is a major determinant of mortality in patients with myocardial infarction
Myocardial Infarction ; Electrocardiography

A study was performed to evaluate the changes of cardiac dimension in 73 patients with infarction and 72 persons (control) without cardiovascular diseases or diseases that influence the cardiovascular system by ultrasound. Results showed that the infarction caused a dilatation of left ventricle and atrium, increasing of volume of the left ventricle in both systolic and diastolic phases. Patients with grade II cardiac failure as killip had dilatation of the left ventricle was more than this in patients with grade I cardiac failure.
