Usefulness of sex steroid hormone levels in predicting coronary artery disease in men.
The relation between sex hormone levels and subsequent risk of a major coronary event was studied in a nested case-control study among 163 men in the Multiple Risk Factor Intervention Trial who later had a major coronary event and in 163 controls. Cases and controls were matched for age, serum cholesterol level, randomization group, randomization date and clinic. Blood samples were collected at baseline before randomization and frozen at -70 degrees C. Follow-up extended over 6 to 8 years. Sixty-one patients had a nonfatal acute myocardial infarction and 102 fatal infarction. Total and free testosterone, total and free estradiol, androstenedione and estrone concentrations were measured. There were no significant differences between cases and controls for any sex hormone level. There was also no difference in the ratio of testosterone to estradiol. Controlling for other cardiovascular risk factors did not change these results. These results do not support previous case-control studies of a relation between sex hormone levels and risk of heart attack among men.
