    Background: The selection of β-blocker for survivors after primary intervention due to acute ST-elevation myocardial infarction seems crucial to improve the outcomes. However, rare comparison data existed for these patients. We aimed to compare the effectiveness of selective β-blockers to that of carvedilol in patients treated with primary intervention. Methods and results: Among the 1,485 patients in the “INTERSTELLAR” registry between 2007 and 2015, 238 patients with selective β-blockers (bisoprolol, nebivolol, atenolol, bevantolol, and betaxolol) and 988 with carvedilol were included and their clinical outcomes were compared for a 2-year observation period. In the clinical baseline characteristics, the unfavorable trends in the carvedilol group were high Killip presentation, lower ejection fractions, smaller diameters, and longer lengths of deployed stents. Although mortality (2.5% vs. 1.7%; p = 0.414) and the rate of stroke (0.8% vs. 0.6%; p = 0.693) were not different between groups, the rate of recurrent myocardial infarction (4.6% vs. 1.2%; p = 0.001) and of target vessel revascularization (4.2% vs. 0.9%; p < 0.001) were lower in the carvedilol group. After eliminating the difference by propensity matching, the similar outcome result was shown (all-cause death, 0.6% vs. 1.0%, p = 0.678; stroke, 0.6% vs. 1.2%, p = 0.479; myocardial infarction, 5.0% vs. 1.2%, p = 0.003; target vessel revascularization, 4.5% vs. 0.7%, p < 0.006) for 595 matched populations. The use of carvedilol was also determined to be an independent predictor for recurrent myocardial infarctions (hazard ratio = 0.305; p = 0.005; 95% confidence interval = 0.13-0.69). Conclusion: Use of a carvedilol in ST-segment myocardial infarction survivor is associated with lower recurrent myocardial infarction events. Thus, it might be the better choice of β-blocker for secondary prevention in ST-elevation myocardial infarction patients treated with primary percutaneous coronary intervention.
