[Immediate and mid-term results following coronary stent implantation in diabetic patients].

INTRODUCTION: We analyzed the clinical and angiographic outcome, including follow-up, in diabetic, patients treated with percutaneous transluminal coronary angioplasty (PTCA) and stenting. MATERIAL AND METHODS: Between January 1995 and December 1999, 770 patients were treated with PTCA, 137 of them with diabetes (DM), 17.7% received 160 stents, average 1.16 stent/patient. Mean age was 58.70 +/- 8.44 years (range 35 to 80 years) and there were 92 men and 45 women. According to the clinical presentation, there were 54% with severe angina based on criteria from the Canadian Cardiovascular Society (CCS). Sixty two percent of patients had prior myocardial infarction and 68% had multivessel disease. Mean vascular obstruction was 90 +/- 6.3% and the ejection fraction was 45.3 +/- 8.7%. RESULTS: The immediate angiographic success was 94.4% in patients with DM. There were complications in 8.4% (acute myocardial infarction, and thrombosis). The average follow-up was 10 mouths (range 6 to 36) in 94% of the cases. The mortality was 4.3%. CONCLUSIONS: These results show that PTCA and stenting in patients with DM is a successful procedure, with few clinical and angiographics complications.
