Distant myocardial infarction: a case report

Abstract

Currently, more and more cases of distant myocardial infarction are being registered. This pathological condition occurs due to an acute decrease in myocardial blood supply, which was provided by a donor artery, which blood supply system is anatomically not directly connected to the affected area. Cases of distant myocardial infarction are sporadic. Therefore, there are difficulties in choosing the right management strategy. During percutaneous coronary intervention, it is possible to perform recanalization of an artery with chronic occlusion, which anatomically supplies blood to the affected wall, and/or donor artery stenting, which supplies the infarction zone due to collaterals. The article presents a case of non-Q wave myocardial infarction of left ventricular anterior wall, which developed in a patient with 90% stenosis in the proximal left anterior descending (LAD) artery, chronic occlusion of the middle LAD segment, and 80% stenosis in the proximal right coronary artery. Direct stenting of the right coronary artery led to a significant increase in the contrast intensity in intersystem collaterals from the posterior interventricular artery to LAD artery. This was accompanied by an improvement in the clinical symptoms and a complete absence of angina throughout the patient’s hospital stay.
