Desfechos tardios da intervenção coronária percutânea com stent farmacológico em pontes de veia safena: dados do registro InCor

ABSTRACT Late Percutaneous Coronary InterventionOutcomes with Drug-Eluting Stent in SaphenousVein Grafts – Data from the InCor Registry Background: The safety and efficacy of drug-eluting stentsin the treatment of saphenous vein graft (SVG) lesions re-mains controversial. This study assessed the late follow-up ofpatients with SVG lesions treated with drug-eluting stents. Methods: Single center registry including patients undergoingSVG interventions using drug-eluting stents (n = 82), withoutclinical or angiographic exclusion criteria, from 2003 to2009. The rates of major adverse cardiac events (MACE),death, acute myocardial infarction (AMI), target vessel revas-cularization (TVR) and stent thrombosis were evaluated. Results: Mean age was 67.8 + 10.2 years, most of themwere male (85.4%), 40.2% were diabetic and 52.4% hadstable angina. An average of 1.45 + 0.5 stents per patientwere implanted and Cypher TM was the stent used in most ofthe cases (61%). Stent diameter was 3.22 + 0.39 mm andstent length was 20.1 + 7.3 mm. Angiographic success ratewas 96.3%. In the 4.1-year follow-up, the rate of MACEwas 28%, death 6%, AMI 19.5% and TVR 18.2%. Therewere two cases of definitive or probable stent thrombosis(2.4%) within the follow-up period.
