[Comparative study of coronary angioplasty in diabetic patients. Immediate clinical and angiographic results and clinical evolution in the first year of follow up].
BACKGROUND
The success of revascularization procedures for coronary artery disease could be lower in diabetic patients.


OBJECTIVE
To report the results of coronary angioplasty in diabetic and non diabetic patients.


METHODS
All angioplasty procedures performed between 1996 and 1999 were recorded. Demographic data, procedure details, hospital outcome and evolution at one year of follow up were analyzed.


RESULTS
During the study period, 358 patients were treated; of these, 79 were diabetics. Despite the greater severity of coronary lesions among diabetic patients the clinical success of the procedure was 92.4% in diabetics and 91.8% in non diabetics. Hospital mortality was 1.3% in diabetics and 0.7% in non diabetics. Major complications occurred in 3.8% of diabetics and 3.2% in non diabetics. One year survival was 95.9% for diabetics and 98% in non diabetics. There were five late cardiac deaths among non diabetics and 3 among diabetics during the year of follow up. The frequency of new revascularization procedures was 4.3% in diabetics and 8.3% in non diabetics. Event-free survival was 95.6% in diabetics and 89.2% in non diabetics.


CONCLUSIONS
Results of angioplasty were similar in diabetic and non diabetic patients in terms of hospital outcome and late follow-up.
