[Dynamics of disorders of ventricular contraction studied by two-dimensional echocardiography 2 years after myocardial infarction].

Two-dimensional echocardiography (ECHO 2D) was performed in 133 patients 1-2, 3-5, 7-10, 21-28 days and 3, 6, 9, 12, 18 and 24 months after myocardial infarction. During 2-years observation after myocardial infarction a gradually diminishing occurrence of left ventricular (LV) systolic wall motion abnormalities, is seen mostly--akinesia. Dyskinesia is the most persistent form of asynergy appearing with similar frequency during the whole study period. Improvement, worsening or no changes of LV asynergy are found with similar frequency in hospital phase. Favourable asynergy changes predominantly++ in the ambulatory phase. Right ventricular (RV) asynergy is found rarely (5%) in transmural inferior infarction only. It coexists with enlargement of RV. RV asynergy is always associated with LV asynergy, mostly of its inferior or posterior wall.
