The study evaluated the correlation between baseline SYNTAX Score, Residual SYNTAX Score, and SYNTAX Revascularization Index and long-term outcomes in ST-elevation myocardial infarction (STEMI) patients with primary percutaneous coronary intervention (PCI) on an unprotected left main coronary artery lesion (UPLMCA).<jats:italic> Background<\/jats:italic>. Previous studies on primary PCI in UPLMCA have identified cardiogenic shock, TIMI 0\/1 flow, and cardiac arrest, as prognostic factors of an unfavourable outcome, but the complexity of coronary artery disease and the extent of revascularization have not been thoroughly investigated in these high-risk patients.<jats:italic> Methods<\/jats:italic>. 30-day, 1-year, and long-term outcomes were analyzed in a cohort of retrospectively selected, 81 consecutive patients with STEMI, and primary PCI on UPLMCA.<jats:italic> Results<\/jats:italic>. Cardiogenic shock (p=0.001), age (p=0.008), baseline SYNTAX Score II (p=0.006), and SYNTAX Revascularization Index (p=0.046) were independent mortality predictors at one-year follow-up. Besides cardiogenic shock (HR 3.28, p&lt;0.001), TIMI 0\/1 flow (HR 2.17, p=0.021) and age (HR 1.03, p=0.006), baseline SYNTAX Score II (HR 1.06, p=0.006), residual SYNTAX Score (HR 1.03, p=0.041), and SYNTAX Revascularization Index (HR 0.9, p=0.011) were independent predictors of mortality at three years of follow-up. In patients with TIMI 0\/1 flow, the presence of Rentrop collaterals was an independent predictor for long-term survival (HR 0.24; p=0.049).<jats:italic> Conclusions<\/jats:italic>. In this study, the complexity of coronary artery disease and the extent of revascularization represent independent mortality predictors at long-term follow-up.<\/jats:p>","DOI":"10.1155\/2019\/8238972","type":"journal-article","created":{"date-parts":[[2019,3,18]],"date-time":"2019-03-18T19:38:14Z","timestamp":1552937894000},"page":"1-9","source":"Crossref","is-referenced-by-count":21,"title":["New
