Lesão no segmento proximal da artéria coronária descendente anterior: resultados entre o tratamento cirúrgico (mamária) e o percutâneo (stent com fármaco)

Objectives: To correlate the permeability and clinical evolution of single and multilateral patients, bearers of obstructive atherosclerosis heart disease in the proximal third of the anterior descending coronary artery (DA), who were submitted to myocardial revascularization using the left internal mammary or underwent a drug eluting stent procedure. Method: This a case history cohort study in which two centers participated. Three hundred patients were retrospectively analyzed, whose lesions were treated at the proximal one third of the DA: in the G-1 group, 150 patients, underwent myocardial revascularization surgery and, the G-2 group, 150 patients, received drug eluting stents, 95 of them received paclitaxel and 55 received sirolimus. All major adverse cardiovascular events were registered during the period (MACE) during the period between the two procedures and the angiographic restudy. Deaths were not included in these MACE, since all patients were restudied through coronariography. There were clinical and angiographic demographic differences between the two groups: the G-1 patients showed a higher incidence of diabetes (29.3% versus 20.0%, p<0.05) and three artery atherosclerosis disease 50% versus 30.6%, p<0.05) with a lower incidence of one artery (13.3% versus 30.6%, p<0.001). Results: The permeability of the two procedures was quite high in both groups. Those patients free of MACE in G-1 RESUMO
