Major Role of Coronary Spasm in the Pathogenesis of Myocardial Infarction at Young Age

The role of coronary vasospasm in the genesis of angina, postulated many years ago, has been recently documented both in resting angina [6, 8] and in some cases of angina on effort [14]. Conversely, the role of coronary vasospasm in the genesis of myocardial infarction (MI), although postulated and even demonstrated in some cases, is still unclear [9]. Therefore, to discuss the role of spasm at young age is difficult.
