[Changes in intracardiac blood flow in the acute period of myocardial infarction (according to the results of 2-dimensional impulse Doppler echocardiography].
Quantitative parameters of intracardiac blood flow were examined by impulse dopplerography in normal subjects and patients with acute transmural myocardial infarction with reference to the severity of disturbance of left-ventricular segmental contractility. The flow rate through the apical region and left-ventricular efferent tract was basically similar in normal subjects and coronary patients without myocardial infarction. Where myocardial segmental contractility was disturbed, changes in flow rate are different at different left-ventricular levels and depend on the site of infarction, the extent of left-ventricular involvement and the condition of intact myocardium. Reduced flow rate in left ventricular cavity and the efferent tract is indicative of a profound depression of both total and segmental left-ventricular myocardial contractility.
