[Myocardial infarct in diabetes mellitus patients. A long-term follow-up]. / Infarto de miocardio en pacientes con diabetes mellitus. Seguimiento a largo plazo.

ABSTRACT

The acute phase and long-term evolution of 249 patients diagnosed as having acute myocardial infarction and admitted to our hospital during the period 1981 to 1983, were studied. They were classified in 2 groups A (non-diabetic patients) and B (diabetic patients). Several variables were analysed in order to determine the differences between both groups. The most accentuated being diabetic patients, female sex, old age, blood hypertension history, cardiac failure, re-extended infarction. The inter-hospital mortality was higher in group B, mainly as a result of cardiogenic shock and left cardiac failure. An out-patients follow-up of acute phase survivors was carried out, between 1 to 96 months, with mean follow-up of 46.7 month in group A and 38.4 in group B, at 8 years the actuarial rate being 77.3% and 55.9% respectively. We conclude that diabetic patients with myocardial infarction register a higher long- and short-time mortality.
