Seguimiento clínico al año de angioplastias coronarias exitosas en pacientes no seleccionados

Background:Re-stenosis after percutaneous Coronary Angioplasty (PTCA) is related to clinical and angiographic features. Aim: To describe the clinical and angiographic characteristic of our patients with coronary cardiopathy subjected to PTCA and the predictor factors for re-stenosis. Material and me...

Aim: To describe the clinical and angiographic characteristic of our patients with coronary cardiopathy subjected to PTCA and the predictor factors for re-stenosis. Material and methods: We gathered the clinical and angiographic characteristics of all patients who underwent a successful PTCA of a native coronary artery. All patients had a clinical assessment one year after the procedure. Patients were classified in Group 1, if they did not have angina or coronary events after the angioplasty or Group 2, if they had angina or a coronary event after the procedure. Only Group 2 patients were subjected to a coronary angiogram. Results: We collected 383 PTCA procedures. Follow up information was obtained in 92.2%. Three hundred forty two patients (89.3%) were assessed one year the procedure. Nine patients (2.3%) died of a cardiovascular cause. Ninety patients (26.3%) were classified in Group 2. In 65 patients, angiographic re-stenosis was demonstrated (19%). Re-stenosis occurred in 36 and 13% of patients with an without Diabetes Mellitus, respectively (p <0.01). The other clinical predictor variables were a history of myocardial infarction (p =0.007), obesity (p =0.041) and hypercholesterolemia (p =0.050). None of the angiographic characteristics predicted restenosis. Stents were protective factors against restenosis (15.6% in stented lesions vs 25.4% in nonstented; p =0.01). Conclusions: Re-stenosis after angioplasty occured in 19% of our patients with angina or coronary events. The clinical variables associated with a higher risk of re-stenosis were diabetes (the main risk factor), previous myocardial infarction, obesity and hypercholesterolemia. Angiographic variables were not associated with re-stenosis. The use of stents decreases the incidence of re-stenosis in all groups)info:eu-repo/semantics/openAccessSociedad Médica de SantiagoRevista médica de Chile v.134 n.11 20062006-11-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0034-98872006001100005es10.4067/S0034-98872006001100005
