Introduction and objectives: We performed a pooled analysis based on patient-level data from the TITAX-AMI and BASE-ACS trials to evaluate the outcome of titanium-nitride-oxide-coated bioactive stents vs drug-eluting stents in patients with ST-segment elevation myocardial infarction at 2-year follow-up. Methods: The TITAX-AMI trial compared bioactive stents with paclitaxel-eluting stents in 425 patients with acute myocardial infarction. The BASE-ACS trial compared bioactive stents with everolimus-eluting stents in 827 patients with acute coronary syndrome. The primary endpoint for the pooled analysis was major adverse cardiac events: a composite of cardiac death, recurrent myocardial infarction, or ischemia-driven target lesion revascularization at 2-year follow-up. Results: The pooled analysis included 501 patients; 245 received bioactive stents, and 256 received drug-eluting stents. The pooled bioactive stent group was associated with a risk ratio of 0.85 for major adverse cardiac events (95% confidence interval, 0.53-1.35; P = .49) compared to the pooled drug-eluting stent group. Similarly, the pooled bioactive stent group was associated with a risk ratio of 0.71 for cardiac death (95% confidence interval, 0.26-1.95; P = .51), 0.44 for recurrent myocardial infarction (95% confidence interval, 0.20-0.97; P = .04), and 1.39 for ischemia-driven target lesion revascularization (95% confidence interval, 0.74-2.59; P = .30), compared to the pooled drug-eluting stent group. These results were confirmed by propensity-score adjusted analysis of the combined datasets. Conclusions: In patients with ST-segment elevation myocardial infarction, bioactive stents were associated with lower rates of recurrent myocardial infarction compared to drug-eluting stents at 2-year follow-up; yet, the rates of cardiac death and ischemia-driven target lesion revascularization were similar.
