Clinical outcomes and complications of treatment with supraflex stent in patients with coronary artery disease: One-year follow-up

Cardiovascular disease is one of the most important causes of morbidity and mortality in the world. Treatment in most patients is percutanseous coronary intervention. One of new generation drug-eluting stent (DES) is Sirolimus Eluting Stent. The current study was aimed to investigate the clinical outcomes and complications of treatment with supraflex stent during one year follow up in patients with coronary artery disease. This cross-sectional study was performed on patients with myocardial ischemia who were candidate for coronary angioplasty between 2017 -2018 in Imam Reza Hospital, Mashhad, Iran. Patients were followed for four primary end points including Target lesion revascularization (TLR), stent thrombosis (ST), myocardial infarction (MI) and cardiac death (CD) for one year. Descriptive data were analyzed by Freidman at a significance level of 0.05. A total of 287 patients were enrolled in the study. There was no TLR, MI, ST and CD records in the one month follow up. Six months follow up demonstrated three TLR patients and three MI patients, but no ST and death were reported. After one year follow up, three cases of CD and four ST cases were found in patients treated with supraflex stent. Based on the Freidman test, the highest rate of TLR was revealed in a six-month follow-up when comparing with one-month and twelve-month follow-up (p = 0.05). No significant relationship was found between the other cases. The most common complications associated with supraflex stent were TLR and MI in six-month follow-up. The most likely occurrence of CD and ST were found in one year follow up.
