Objective: The main goal of this study was to determine the inmediate clinical and angiographic results in patients suffering from unstable angina submitted to coronary angioplasty with/without implantation of bare stents in a tertiary hospital, to see the influence of diabetes mellitus on this group, as well as their clinical evolution after a 6 month follow up. Material and methods: this is a transeccional descriptive study with consecutive patients chosen between october 2001 and january 2002. Demographic characteristics, procedure indications, type of intervention, results and complications were included. The patients were contacted over the phone 6 months after the coronary intervention. Results: 42 patients were included (33 males/10 females), 13 of them were diabetics. Sixty vessels were treated, in 47 vessels (77 coronary angioplasty plus stent insertion was used, and in 11 (18.33%) angioplasty alone. Fifty six vessels were successfully treated, 2 were not (1 of these patients died) and other 2 could not be completed, for an altogether success rate of 93.33 (56 out of 60 vessels). The average stent/vessel rate was 1.15, hospital stay averaged 6.14 days, and the in-hospital post procedure stay was 2.7 days. Thirty eight of 42 patients were available for a 6 month follow up, 26 (68.42%) had no cardiac events, 6 of which were diabetics . Of the remaining 12 (31,58%), of which 4 were diabetics, 8 had stable angina, 2 had unstable angina, and 1 had a non fatal myocardial infarction. Five patients required a new revascularization procedure, 2 coronary angioplasty plus stenting, 1 angioplasty alone, and 2 coronary surgery. Two cardiac deaths occurred, 1 had a fatal infarct and the other had cardiogenic shock. The complication rate for non diabetics was 30% (8 of 26) and that one for diabetics was 33% (4 of 13). Conclusion: coronary angioplasty at the San Juan de Dios Hospital is done with good results, a low complication rate and short hospital stay. Diabetes mellitus was not an adverse prognostic factor in this group of patients.
