[Detection of multiple lesions of the coronary arteries in patients after myocardial infarction. Data of two-dimensional stress echocardiography during the test of transesophageal atrial electric stimulation].
The method of two-dimensional stress echocardiography with transesophageal atrial electrostimulation was used for determination of patients with high risk of complications among those who had survived myocardial infarction. The results of the test were compared to the degree of the coronary artery lesion. The highest sensitivity of the method (94%) in identification of patients with 2 or 3 involved coronary arteries was registered when appearance of new areas with damaged local contractility was used as a criterium. When depression of the ST segment for more than 2 mm or decrease of the left ventricular total ejection fraction for more than 5% was used as a criterium, the sensitivity of the method was correspondingly 72 and 78%.
