Abstract
Background: Clinical and angiographic results with Cobalt Chromium stents implanted into de novo lesions of native coronary arteries seem to confirm the high efficacy of treatment using this type of stents.
Objectives: This study is designed to study In-hospital and Intermediate Term outcomes of Cobalt Chromium Alloy Stents in Patients Undergoing elective percutaneous coronary intervention (PC1).
Methods: Hundred patients who had elective percutaneous coronary intervention using cobalt chromium stent to single de novo native coronary artery lesion & diameter stenosis of 70% or more were included to study in-hospital & 6 months follow-up for Major Adverse Cardiac Events (MACE).
Results: No mortality, no myocardial infarction (MI), or major bleeding were reported during the in hospital follow-up period. The total MACE during six-month follow-up was 17% (one MI case (1%), 16 (16%) Target Lesion Revascular-ization (TLR) & no mortality). Smaller stent diameter & longer stent length were associated with more TLR.
Conclusion: Thin-strut cobalt chromium alloy stents have been found to be safe in the first 6 months after intervention. Although restenosis is still a challenge, using bigger stent diameters and short length stents has shown to decrease restenosis rates and TLR.
