| Popis: | Aim. To study the diagnostic value of myocardial function parameters to assess their predictive ability in relation to left ventricular (LV) global contractility in patients after myocardial infarction (MI).Material and methods. The final analysis included 97 patients with MI aged 55,9±8,6 years. We performed standard two-dimensional echocardiography and speckle tracking echocardiography with analysis of following myocardial function parameters: global work index (GlobalWI, mm Hg %); global constructive work (GlobalCW, mm Hg %); global wasted work (GlobalWW, mm Hg %); global work efficiency (GlobalWE). The probability of ejection fraction (EF) reduction was analyzed using ROC curves using three criteria. The function parameters with the maximum sum of sensitivity and specificity were selected as the cut-off point.Results. On days 7-9 after MI, depending on the EF, patients were divided into 3 groups: "REF" — patients with EF |
