Objective We sought to study the clinical outcomes of bifurcation stenting in patients who presented with stent thrombosis segment elevation myocardial infarction (STEMI). Background Patients with STEMI are usually excluded from randomized bifurcation studies. There is limited information for bifurcation stenting in this population. Methods All STEMI patients who were randomized were retrospectively reviewed from DKCRUSH II (double kissing, double crush) database. DKCRUSH II is a multicenter, randomized study of provisional stenting (PS) versus the DK crush stenting techniques. A total of 370 patients with bifurcation lesions were randomized and of this group a total of 63 patients with STEMI were found. This group of STEMI included 30 patients in the PS group and 33 patients in the DK crush stenting group. Results There were no differences in terms of contrast used, procedure time, and fluoroscopy time. Procedural success rates were 97% in all patients with STEMI, with 100% in the PS group and 94% in the DK crush stenting group. During the procedure, there were two patients with less than TIMI 3 (thrombolysis in myocardial infarction) flow in the main vessel of the DK crush group However, TIMI 3 flow was 100% in the side branch for both groups. Cumulative 12‐month major adverse cardiac event (MACE) was 22% in the whole STEMI group, whereas PS and DK crush groups were 23% versus 21%, respectively ( P = NS). There were no differences in in‐hospital, 6‐month, and 12‐month MACE in these two groups. At 6 and 12 months, there were two cardiac deaths in the PS group but without statistical significance when compared with the DK crush stenting group (7% vs. 0%, P = NS). Conclusion Bifurcation stenting in patients with STEMI is safe and feasible. The immediate and midterm clinical outcomes were comparable between PS and DK crush stenting. © 2013 Wiley Periodicals, Inc.
