[Does anginal pain influence the medical care-seeking behavior of patients in the prodromal phase prior to an acute myocardial infarction. Results of a post-infarction late potential study.].

The aim of the study was to determine the proportion of high-risk patients who received appropriate antianginal therapy in the prodromal phase prior to a myocardial infarction, as an indicator of medical care seeking behavior. To this end, 606 male infarct patients aged 29-65 years were retrospectively interviewed 17-21 days after acute myocardial infarct. It was found that 77% of all patients (465/606) suffered from anginal pain, but only 32% of the patients with angina pectoris were receiving antianginal therapy in the prodromal period before acute myocardial infarction. Patients not taking medication were significantly younger than those with antianginal medication; they were more often smokers; they were less often suffering from high blood pressure; they expressed more pronounced nonacceptance of the risk; their history of anginal pain was significantly shorter; and they belonged more often to the patient group with a first myocardial infarction. In stepwise logistic regression analysis, high blood pressure, older age and exhaustion were found to be associated with medical treatment before infarction in the patient group with first myocardial infarction. In patients with recurrent infarction, continued smoking and denial of the risk remained predictive of nonmedication.
