Unstable angina is an ischemic heart syndrome characterized by anginal pain that occurs with increasing frequency. It is triggered by less and less intense efforts, takes place often during rest and tends to be of longer duration. In Panama, it represents the second leading cause of mortality among ischemic heart diseases, right below acute myocardial infarction.
This is a retrospective analysis of cases and controls, restrictive on age and sex, not matched, adjusted to smokers, that took place in the Arnulfo Arias Madrid Metropolitan Hospitalary Complex. From it was determined the possible relation between risk factors and the development of unstable angina. One hundred and forty cases with controls were studied, all males. Patients with high blood pressure had an adjusted OR of 5.09 (95% IC 2.38-11.19); obesity showed an adjusted OR of 4.22 (95% IC 2.04-8.15); diabetes mellitus type 2 had an adjusted OR of 4.29 (95% IC 2.20-8.33); and family history had an OR of 4.92 (95% IC 2.46-9.95). Sedentarism was not adjusted against smokers due to the fact that the association with unstable angina was random.
