[Comparative study of coronary angioplasty in diabetic patients. Immediate clinical and angiographic results and clinical evolution in the first year of follow up]. / Estudio comparativo de la angioplastia coronaria en pacientes con diabetes. Resultados clínicos y angiográficos inmediatos y evolución clínica en el primer año.

BACKGROUND: The success of revascularization procedures for coronary artery disease could be lower in diabetic patients. AIM: To report the results of coronary angioplasty in diabetic and non diabetic patients. PATIENTS AND 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.
