Color-flow imaging:
Which of the following is not correct regarding the condition shown on the color-flow imaging echocardiogram?
A. It occurs at rate of approximately 3% to 5% of myocardial infarction
B. If the timing of acute myocardial infarction is known, early use of thrombolytic agents may lead to reopening of the occluded vessels, thus reducing its incidence
C. It is virtually always associated with transmural rather than nontransmural myocardial necrosis.
D. Intra-aortic balloon counterpulsation (IABCP) may offer temporary hemodynamic support to buy time for subsequent intervention.
E. This event usually occurs immediately at the onset of an acute infarction.
