[Criteria of appropriate incomplete revascularization in patients with ST-segment elevation myocardial infarction in multivessel lesion of the coronary bed].
The study was aimed at analysing the outcomes of multivessel revascularization by means of percutaneous coronary intervention (PCI) in a total of 190 patients presenting with ST segment elevation myocardial infarction (STEMI) and multivessel lesion (MVL) of coronary arteries. Patients with unsuccessful PCI or those having received no planned second stage of revascularization for any reason were excluded from the study. The patients were subdivided into two groups: Group One comprised those having received appropriate complete revascularization (CR) within the framework of multivessel stenting (MVS) during primary PCI or a stagewise approach (n=137), Group Two included patients with the so-called appropriate incomplete revascularization (AIR) after MVS or stagewise PCI (n=53). In all cases IR was considered appropriate due to the presence of the corresponding anatomical and/or functional criteria used in the literature but not studied in relation to the cohort of patients with STEMI: (1) small arterial diameter (
