Percutaneous revascularization of multivessel coronary disease with systematic stent implantation. Immediate results and clinical follow-up and middle term angiography

The aim of this retrospective study was to assess the immediate and medium-term clinical and angiographic results of multiple angioplasty with stenting in 100 consecutive patients with multivessel coronary artery disease. The mean age of the population was 62 +/- 11 years. Two hundred and eight lesions were treated (2.5 +/- 0.7 per patient) with implantation of 1.14 +/- 0.4 stents per lesion. The angiographic success rate was 98.7%. There were 5 major complications in the hospital period: 3 deaths, including 2 of cardiac causes, one coronary bypass procedure and one Q wave myocardial infarction. During follow-up (17 +/- 6 months), eight patients died (5 of cardiac causes) and secondary revascularisation procedures were required in 22 patients. At 6 months, the angiographic restenosis rate was 32% per lesion, 28.8% per stent and 33 patients had at least one restenosis.
