Variables asociadas a reestenosis clínica en pacientes con intervencionismo coronario percutáneo con stent convencional. Variables related to clinic restenosis in patients after percutaneous coronary interventionism with conventional stent.

Abstract

A descriptive study of traverse court was carried in all the patients who recieved percutaneouscoronary interventionism with implantation of conventional intracoronary stens, in theperiod comprehended from April 2005 until August 2007, in the Department of Hemodynamicsand Interventional Cardiology of the Service of Cardiology from the Hermanos AmeijeirasHospital, all patients were followed up during one year. With the objective of characterizingthe behavior of the different variables of clinic coronary reestenosis. We study 189 serialcases, of which 29 presented reestenosis and 160 did’n. It was found that the more frequentage group was the one ranging from 50 to 59 years, in the patients with reestenosis, and theone of 60 to 69 years in the patients without reestenosis and in both the masculine sex prevailed.In almost one half of the patients existed the concomitance of two or more risk factorsand the arterial hypertension constituted the prevalent factor in both groups. The unstableangina occupied the second place in frequency, in patients with reestenosis, followed bythe stable angina; while in the patients without reestenosis, the habit of smoking and thestable angina were the factors continuing in frequency. The unstable angina resulted prevalentin patients with reestenosis, compared with those without restenosis. In the group ofrestenosis the multivessels disease was superior. The anterior descendant coronary arterywas the most affected in both groups. The stent of ≥18mm of longitude was used in almostthe totality of the cases in both groups. The ≤3mm of diameter stent was more frequentlyused in patients with reestenosis, showing an association statistically relevant. In bothgroups the complex lesions prevailed (B2C).We concluded that among the variables of clinical reestenosis in patients with percutaneouscoronary interventionism, the prevailing turned out to be the arterial hypertension, the anginasand the smoking habit and that other variables, as the longitude of the stent, the diameterof the vessel, localization and the multivessel affection can influence, although the diameterof the vessel ≤3mm was the only one who marked significant differences.
