Six-months Prognosis of Cobalt Chromium Stents Versus Stainless Steel Stents in Diabetic Patients

Abstract

Background—The clinical outcome in diabetic patients undergoing percutaneous coronary intervention (PCI) is inferior to that in non-diabetic patients. Several aspects of diabetic coronary artery disease appear to be responsible for this observation. In comparison with stainless steel stent, cobalt chromium stent has a higher radial strength and radio-opacity for similar electronegativity, this allow for the production of thinner struts with a similar radiological visibility. Therefore we studied and compared six-months prognosis of cobalt chromium stent versus stainless steel Bare metal stents in diabetic patients undergoing PCI.
