TOPICAL DIAGNOSTICS OF SINGLE CORONARY ARTERY OCCLUSION IN ST ELEVATION MYOCARDIAL INFARCTION PATIENTS

Abstract

In ST elevation myocardial infarction (STEMI) diagnostics, main role is played by electrocardiography (ECG), which makes it to define MI itself as, in many cases, localization of occlusion.

Aim. To investigate on the efficacy of topical diagnostics of coronary arteries lesion in STEMI with single vessel disease, by ECG.

Material and methods. Totally, 200 STEMI patients (59,9±0,93 лет) included, with single vessel disease. The accuracy of diagnostics evaluated, of the coronary occlusion localization in three coronary arteries and in 2 segments in each of them, by original diagnostical algorithm.

Results. An algorithm invented, for diagnostics of multivessel disease of three coronary arteries, that makes it to perform topical diagnostics of the left anterior descending artery (sensitivity 92,2% and specificity 96,5%), of the right coronary artery (92,3% and 95,1%) and, at lesser grade, of the circumflex artery (81,5% and 66,7%), as two sectors in each of them with sensitivity 48,8-66,7% and specificity 60,0-74,5%.

Conclusion. In STEMI, an algorithm invented, and the software that calculates risk of occlusion of an exact coronary artery and its segments, as the risk of fatal outcome.
