Medical Research: What are the main findings of the study?
Answer: The time window of DES (drug-eluting stent) failure is widely variable from soon after DES implantation to several years after DES implantation. We observed patients with late DES failure are commonly presented with acute coronary syndrome. We hypothesized that temporal patterns of DES failure may be different, and analyzed all patients with first DES failure at our institution. We found that late drug-eluting stent failure is more likely to progress to acute myocardial infarction, aggressive angiographic patterns, and worse outcomes following retreatment.
