La diabetes es una enfermedad con elevado riesgo cardiovascular. El objetivo fue evaluar la mortalidad intrahospitalaria y en el seguimiento a largo plazo de los pacientes diabeticos con infarto agudo de miocardio tratados con angioplastia primaria y determinar sus predictores. Material y metodos: Se incluyeron de forma retrospectiva 866 pacientes durante enero de 1993 y diciembre de 2013. Se evaluaron 100 sujetos con diagnostico de diabetes. La mediana de seguimiento fue de 121 meses. Resultados: De los 100 pacientes diabeticos evaluados (11.56% del total), el 86% fueron hombres y el 50% tenian mas de 50 anos. El 76% estaba en Killip-Kimball 1 al ingreso y el 16% en Killip-Kimball 4. La localizacion mas frecuente fue la anterior y el 65% presentaba lesion de 2 o mas vasos coronarios. Se observo una mortalidad intrahospitalaria del 15%, cuyo unico predictor resulto el Killip-Kimball de ingreso. La mortalidad alejada fue del 35%, y solamente la edad, el Killip-Kimball al ingreso y el uso de Inhibidores de la enzima convertidora de angiotensina resultaron variables con significacion estadistica. A diferencia de la poblacion diabetica, el Killip-Kimball al ingreso no se asocio significativamente a la mortalidad alejada en no diabeticos. Conclusion: Esta poblacion de pacientes diabeticos se caracterizo por ser mas anosa y por presentar lesion de 2 o mas vasos coronarios. El shock cardiogenico fue la unica variable predictora independiente de mortalidad intrahospitalaria y, junto con la edad y el uso de inhibidores de la enzima convertidora de angiotensina, de mortalidad en el seguimiento a largo plazo

Diabetes mellitus is one of the major risk factors for coronary artery disease. The aim of this study was to evaluate in-hospital mortality and during follow-up of diabetic patients with acute myocardial infarction treated with primary angioplasty and to determine its predictors.Eight hundred and sixty six patients were retrospectively enrolled from January 1993 to December 2013. A hundred patients with a diagnosis of diabetes were evaluated. The median follow-up was 121 months in 90% of the population.Of the 100 diabetic patients included (11.56%) 86% were male and 50% older than 70 years. Overall, 76% presented with a Killip-Kimball grade of 1 at admission and 16% presented with a Killip-Kimball 4. The most frequent location of myocardial infarction was anterior and 65% had 2 or more coronary vessel disease. In-hospital mortality was 15%. The only independent variable significantly associated was the Killip-Kimball at admission. Mortality during follow up was 35% and its independent predictors were: age, Killip-Kimball at admission and use of angiotensin-converting enzyme inhibitors Interestingly, in the non-diabetic group, Killip-kimball at admission failed to predict long-term mortalityThis group of diabetic patients was older, and with a higher prevalence of 2 or more vessel disease. Cardiogenic shock on admission was the only independent predictor of in-hospital death and along with age and angiotensin-converting enzyme inhibitor use, an independent predictor of mortality during long term follow-up.
