THE RELATIONSHIP BETWEEN THE MORPHOLOGICAL CHARACTERISTICS OF INTRACORONARY THROMBI AND THE PROBABILITY OF ACHIEVING ADEQUATE BLOOD FLOW IN THE INFARCTRELATED CORONARY ARTERY

Abstract

Summary. Purpose. To study the relationship between the morphological characteristics of intracoronary thrombi and the probability of achieving adequate blood flow in the infarctrelated coronary artery in patients with ST-segment elevation acute myocardial infarction (STEMI) after primary percutaneous coronary intervention (PCI). Materials and methods. The analysis included 98 patients with STEMI who, in the first 12 hours from the onset of symptoms, underwent PCI and received thrombotic masses during manual thromboaspiration. The latter was analyzed macroand microscopically. Using the method of logistic regression with progressive selection, characteristics of thrombi affecting the probability of achieving adequate blood flow were identified. Results. From the set of factors investigated in the course of performing the work using the logistic regression method, 5 factors were separated that, when combined, have an impact on the probability of reaching TIMI 3 blood flow after PCI: old thrombi, layered structure, microchannels, inflammatory infiltrate on the periphery, and white thrombi Conclusions. The structure of the intracoronary thrombus has a significant connection with the probability of achieving adequate blood flow through the infarctrelated coronary artery.
