ON THE ASSESSMENT OF THE LEFT VENTRICLULAR MYOCARDIAL PERFUSION IN MYOCARDIAL INFARCTION USING SINGLE PHOTON EMISSION COMPUTED TOMOGRAPHY

Abstract

SUMMARY. On the basis of single photon emission computed tomography of the myocardium (SPECT) with Technetril 99mTc performed in 81 patients with myocardial infarction (MI), we confirmed the proportion of myocardial segments of the left ventricle (LV) with varying degrees of RP inclusion and, therefore, with varying degrees of perfusion impairment. In 75% of patients, reduction of hypoperfusion area in the remote period after myocardial infarction has been revealed compared to the acute period. The relation between slow ECG evolution with the severe impairment of left ventricular myocardial perfusion has been showed. The relation between the degree of impairment of LV myocardial perfusion (by SPECT) and its contraction (according to the two-dimensional echocardiogram) has been revealed. It is shown that one of the leading factors in the restoration of myocardial perfusion is the time of intracoronary intervention.
