[Myocardial infarct immediately after a normal exercise test].
Two cases of myocardial infarction immediately following a normal stress testing, are described. The incidence and possible pathophysiological mechanisms are discussed. In one of the patients it was difficult to establish the pathophysiological mechanism which was the cause of the ischemic event. In the other, the coronary arteriography revealed only minimal obstructive disease. Therefore, coronary vasospasm with thrombus formation as a cause of the infarction ia an interesting speculative possibility in view of the angiographic findings. Acute myocardial infarction after a normal electrocardiographic response to maximal exercise testing is extremely rare, and the precise pathophysiologic mechanism that leads to his complication is not clear.
