Estudio comparativo de la angioplastia coronaria en pacientes con diabetes: resultados clínicos y angiográficos inmediatos y evolución clínica en el primer año / Comparative study of coronary angioplasty in diabetic patients: clinical and angiographic results and clinical evolution at 1 year of follow up

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 percent in diabetics and 91.8 percent in non diabetics. Hospital mortality was 1.3 pecent in diabetics and 0.7 percent in non diabetics. Major complications occurred in 3.8 percent of diabetics and 3.2 percent in non diabetics. One year survival was 95.9 percent for diabetics and 98 percent 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 percent in diabetics and 8.3 percent in non diabetics. Event-free survival was 95.6 percent in diabetics and 89.2 percent in non diabetics. Conclusions: Results of angioplasty were similar in diabetic and non diabetic patients in terms of hospital outcome and late follow-up

Angioplastía en infarto agudo de miocardio: resultado inicial y seguimiento alejado / Angioplasty in acute myocardial infarction: early and late results

Background: The usefulness of angioplasty in the first hours of an acute myocardial infarction is widely demonstrated. However, its long term effects are less well known. Aim: To report the effects of coronary angioplasty on early and late outcome of patients with acute myocardial infarction. Patients and methods: A non-randomized, consecutive and retrospective analysis of the hospital and late outcome of 70 patients, aged 35 to 85 years, subjected to coronary angioplasty during an acute myocardial infarction. Patients were followed during 12 to 60 months. Results: Angioplasty was performed 5.3 ñ 5 hours after the initial symptoms. Anterior descendent artery was occluded in 63 percent of patients with a 99.5 percent luminal occlusion and TIMI 0-1 anterograde flow. An angiographic success was achieved in 83 percent of procedures with a residual stenosis of 32.3 percent. Recurrent ischemia was observed in 6 percent of patients, that were treated with a new revascularization procedure. Thirteen percent of patients died, all due to cardiogenic shock. Severe ventricular failure and failure of revascularization influenced mortality. During the first year of follow up there was a 3.3 percent mortality and 3.3 percent of patients required a new revascularization procedure. Eighty percent of patients were asymptomatic and event-free. Conclusion: Angioplasty was a useful therapeutic procedure in this group of patients
