Key result
Women aged 40-54 with myocardial infarction had fewer left ventricular abnormalities (specifically in non-Q wave infarctions) and fewer collaterals compared to men.
Why the study?
Are there sex differences in cardioangiographic findings after myocardial infarction?
Observational (n=119)
Are there sex differences in cardioangiographic findings after myocardial infarction?
Following myocardial infarction, women aged 40-54 exhibit fewer left ventricular abnormalities (specifically in non-Q wave MI) and fewer collaterals compared to men, despite similar rates of coronary abnormalities.
May support sex-specific post-MI evaluation in women 40-54; hypothesis-generating and should not yet change practice.
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.

Johansson et al. (1984) conducted an observational in Myocardial infarction (n=119). Female sex vs. Male sex was evaluated on Cardioangiographic findings (left ventricular abnormalities, coronary abnormalities, collaterals). Women aged 40-54 with myocardial infarction had fewer left ventricular abnormalities (specifically in non-Q wave infarctions) and fewer collaterals compared to men.
