Long-Term Clinical Outcome After Implantation ofsecond-generation bare-metal stents

Background and Coronary artery Stenting is known to improve the outcome for ischemic heart disease. Many clinical studies have been performed to determine the long-term outcome of coronary Stenting and most of them were based on first-generation bare-metal Stents. The aim of this study is to evaluate long-term (24 6.4 month) results of second-generation bare metal stent. From August 2004 to September 2006, one hundred and twenty eight (128) consecutive patients with significant coronary artery stenosis underwent elective angioplasty and stent implantation, using second generation bare metal stent (BMS). Clinical outcome were analyzed after (246.4) months. The Primary end point was based on the incidence of MACE (MI, Death, and Repeat Revascularization). One hundred and forty four (144) bare metal stents were implanted in 134 Vessels. The Mean age was 57 10.4 years, 72% of patients were male and 35.2% were diabetic with 98.4% in- patient hospitalization success rate. Thirteen (10.3%) patients had MACE during the follow-up period (4MI, 3CABG, 2 Deaths and 4R-PCI). Independent Predictor of MACE was Unstable Angina, Prior PCI, Prior CABG, stent diameter and post PCI plavix dose. Our study demonstrated second generation bare metal stent, is superior to the first generation one with a greater survival rate and lower incidence of MACE.
