[X-ray-morphological characteristics of the coronary reperfusion phenomenon in patients with myocardial infarct during thrombolytic therapy].

An analysis was made of the findings of angiographic studies (coronary angiography and left ventriculography) performed in 57 patients with myocardial infarction along with successful coronary thrombolysis before thrombolytic therapy, at coronary reperfusion (CR), and on days 24 and 28 of the disease. The analysis defined two types of restoration of coronary blood flow: (1) gradual ("slow") and (2) single ("rapid") CR. Angiographic signs of coronary thrombosis in the first hours of myocardial infarction, complicated pattern of a residual stenosis, and more marked left ventricular myocardial dysfunction on day 28 of the disease were more frequently encountered in patients who had undergone "rapid" CR, whereas the uncomplicated pattern and high degree of a residual stenosis were seen in patients who had received "slow" CR. At the same time left ventricular myocardial contractility changed to a lesser extent on day 28 of myocardial infarction.
