    Abstract:
    The Authors have taken into account 21 patients who complained of myocardial infarction before they were 30 years old. We performed coronary angiography, left ventriculography and left cardiac catheterization in all the patients. In 20 cases we found atherosclerotic alterations (50 or greater obstruction) at least in one of the three main braches of coronary tree. The coronary angiography in one patient showed a picture of dissection of right coronary. The alterations are localized more frequently on the anterior descending branch than on the right coronary. On the contrary we found very seldom atherosclerotic lesions on the circumflex artery. Monovascular alterations were more frequent than plurivascular alterations (more than 40% of the total). Left ventricular function was out of order in almost all cases. In summary the important differences between young patients with myocardial infarction and older patients are the following: 1) from the clinical point of view the sudden onset of myocardial infarction without previous symptoms of angina pectoris; 2) from the angiography point of view high incidence of monovascular alterations and low incidence of collateral circulations.
