[Two consecutive cases of myocardial infarction among young women in reproductive age and without risk factors]. / Due casi consecutivi di infarto miocardico in donne giovani in età fertile ed in assenza di concomitanti fattori di rischio.

Coronary artery disease does not occur in all the patients with acute myocardial infarction. Coronary artery diseases occurs in 97% of cases; in the other 3% of cases, myocardial infarction is caused by coronary spasm (40%, intracoronary thrombosis (60%) due to platelet hyperreactivity, peripartum thrombophilia or use of oral contraceptives. Myocardial infarction in young women is an infrequent event. Spontaneous coronary artery dissection is a rare cause of acute myocardial infarction that typically occurs during the peripartum period. A few cases of myocardial infarction in premenopausal women with no risk factors for coronary artery disease and normal coronary arteries have been reported. We describe 2 consecutive cases of acute myocardial infarction occurred in young, premenopausal women, without risk factors for cardiovascular diseases.
