[Acute myocardial infarction in the intensive care unit. Survival analysis].
BACKGROUND
Acute myocardial infarction (AMI) is caused by total occlusion of the coronary artery lumen. Ischemic heart disease is the main cause of death in industrialized countries, it being more frequent in men, although more fatal in women. Its mortality rate increases after fifty years of age.


OBJECTIVE
To perform a survival analysis of the patients with AMI diagnosis in the ICU of the Hospital of Cabueñes; to learn the relationship existing between the mortality rate, site and types of AMI. Patients and method. Retrospective descriptive study of 253 patients diagnosed of AMI in the year 2001 by review of clinical records and telephone follow-up. The variables used were age, gender, site and type of AMI. The SPSS statistical program was used to obtain the results.


RESULTS
Age above 65 years and anterior site of AMI increase mortality. No significant differences are observed in regards to gender and electrocardiographic type. Post-infarction mortality is very high in the first days, followed by a progressive decrease in the follow-up.


CONCLUSIONS
Mortality is not conditioned by the different types of AMI and it is seen to be greater during the stay in the ICU.
