Sex differences in cardioangiographic findings after myocardial infarction

The cardioangiographic findings in 50 women 40-54 years of age were compared with those of a series of 69 men with infarction recruited from the same catchment area and investigated according to the same principles. Women less often had left ventricular abnormalities than men; this difference was mainly confined to patients with non-Q wave infarctions. There was no difference in the prevalence of left ventricular abnormalities among women and men with Q wave infarctions. No major sex difference was found in the prevalence of coronary abnormalities. Collaterals were less common in women than in men.
