Second-generation versus first-generation drug-eluting stents for the treatment of patients with acute coronary syndromes and obstructive coronary artery disease.
Randomized trials and registries have shown that drug-eluting stents (DES) have an overall better performance than bare-metal stents in patients treated in the setting of both ST-segment and non-ST-segment elevation acute coronary syndromes, mainly by reducing restenosis. Whether or not the use of newer second-generation devices (vs. first-generation DES) differs in these high-risk patients remains to be determined. ⋯ Our results suggest that both first-generation and second-generation DES seem to be similarly effective in patients undergoing a percutaneous coronary intervention in the setting of acute coronary syndromes. However, newer second-generation devices may offer potential advantages because of a significantly lower incidence of ARC-definite ST.
