[Atherosclerotic lesions of the coronary arteries in acute myocardial infarction: effects on myocardial contraction, disease course and prognosis].

Coronary arterial affection (CAA) is an objective indicator, closely related to cardiac contractility as well as clinical severity and immediate prognosis of myocardial infarction. The progress of CAA is associated with more pronounced disorders of cardiac contractility, higher rates of severe complications and less optimistic immediate prognosis. Long-term prognosis is not affected by the magnitude of CAA in postmyocardial-infarction patients.
