New Predictors of Early and Late Outcomes after Primary Percutaneous Coronary Intervention in Patients with ST-Segment Elevation Myocardial Infarction and Unprotected Left Main Coronary Artery Culprit Lesion

Table 6

Univariate and multivariate Cox survival analyses adjusted for cardiogenic shock, initial TIMI flow, and age. BMS = bare-metal stent, DES = drug-eluting stent, LM = Left Main, PCI = percutaneous coronary intervention, and TIMI = Thrombolysis in Myocardial Infarction.
