Abstract
Background:Stent thrombosis (ST) is a serious complication after drug-eluting stents (DES) implantation. To identify the risk factors of mortality following ST, we evaluated adverse event reports used for safety measures after approval. Methods and Results:Between July 2004 and August 2019, 2,887 ST case reports were submitted to the Pharmaceutical and Medical Device Agency. Reports of probable or possible ST (n=604), with insufficient data regarding in-hospital outcome or duration between procedure and ST occurrence (n=37) or duplicate reports (n=191) were excluded. Accordingly, 2,045 reports with definite ST were analyzed. Among the subjects, there were 286 in-hospital deaths (14.0%). Multivariate logistic regression analysis revealed that left main trunk (LMT) (odds ratio [OR]: 4.76, 95% confidence interval [CI]: 3.26–6.96), chronic heart failure (CHF) (OR: 2.88, 95% CI: 1.61–5.14), hemodialysis (OR: 2.69, 95% CI: 1.66–4.36), prior stroke (OR: 2.28, 95% CI: 1.15–4.51), over 70 years old (OR: 1.62, 95% CI: 1.22–2.16), and right coronary artery (OR: 0.41, 95% CI: 0.27–0.63) were independent factors for in-hospital death after DES-ST. Conclusions:LMT, CHF, hemodialysis, prior stroke, and older age were independently associated with higher risk of in-hospital death following DES-ST. If target patients have these factors, maximum preventive strategies against ST occurrence, including adequate dual-antiplatelet therapy duration and optimal DES deployment procedures, are required.Keywords
