Long-term clinical outcome after implantation of second-generation bare-metal stents

ABSTRACT

Many clinical studies have been performed to determine the Long-term outcome of coronary Stenting, most of them were based on first-generation bare-metal Stents. This study evaluated long-term [24 +/- 6.4 month] result of second-generation bare metal stents [BMS]. A consecutive series of 128 patients with symptomatic coronary artery disease [CAD] treated electively with second generation bare metal stents between august 2004 and September 2006 was included. Clinical outcome were analyzed after [24 +/- 6.4] months. The Primary end point was based on the occurrence of major adverse cardiac events of MACE [MI, Death, and Repeat Revascularization]. One hundred and forty four bare metal stent were implanted in 134 Vessels. The Mean age of patients was [57 +/- 10.4] years, 72% of patients were male and 352% were diabetic with 98.4% in-hospital success rate. Thirteen [10.3%] patients had MACE during Follow-Up Period [4M1, 3CABG, 2Death and 4R-PCI]. Independent Predictor of MACE was Unstable Angina. Our study showed second generation bare-metal stents is superior to the first one due to better survival rate and lower incidence of MACE
