[Extent of left-ventricular damage after myocardial infarction and the occurrence of mural thrombi].

The aim of the study was to estimate a detailed relationship between the extent of left ventricular damage after myocardial infarction (MI) and occurrence of mural thrombi examined with two dimensional echocardiography (2Decho). The examinations were undertaken in 47 patients (pts) (age 40-86 years) after transmural anterior MI. 2Decho was performed in all pts according to American Society of Echocardiography from the is day to the 4th month after MI. Heger index was used for the estimation of LV wall motion disturbances. The criterion of mural thrombus was the presence of an additional echo by LV wall visible in at least two echocardiographic views. It was determined that the incidence of mural thrombi is correlated with statistically significant larger LV damage expressed with higher Heger index and higher number of hypo-, a-, and dyskinetic LV segments. The study revealed the relationship between the extent of LV damage after MI, the presence of LV dyskinesia, LV enlargement, ST segment elevation in ecg and the incidence of mural thrombi.
