Applying DESyne coronary stent system in patients with ischemic heart disease: experience from Jordan

BACKGROUND: The safety and efficacy of drug-eluting coronary stenting have been established for various degrees of severity of coronary artery disease. The DESyne is a contemporary cobalt–chromium thin-strut stent which has been studied in low-risk patients so far. AIM: The aim of this study was to evaluate the safety, efficacy and performance of the DESyne stent in patients with an indication for coronary stent implantation at the King Abdullah University Hospital (KAUH), Jordan. PATIENTS AND METHODS: Hospital records for all patients implanted with DESyne stent were retrospectively reviewed. Specific clinical events were recorded for all cases, and their incidence rates were estimated by the Kaplan–Meier method. A total of 715 patients (79.3% males and 58.3% with diabetes) with a mean age of 57.8±10.3 years were enrolled in this study. An acute coronary syndrome was the most frequent indication for stenting in 86.3% of the patients (unstable angina 72.0%, myocardial infarction [MI] 14.3%). A total of 849 lesions (1.2 lesions/patient) were treated with the DESyne stent. RESULTS: After 1 year of follow-up, the death rates from cardiac or noncardiac causes were 0.6% and 1.1%, respectively. MI was observed in 0.9% of the cases, and an ischemia-driven revascularization was performed in 0.8% of them. The definite/probable stent thrombosis rate was 1.1%. CONCLUSION: Favorable clinical event rates including cardiac death, MI and stent thrombosis were observed for the DESyne stent in ischemic heart patients especially those with high prevalence of diabetes mellitus and acute coronary syndrome.
