Laboratory diagnosis of an acute myocardial infarction (MI)is most accurately determined with which of the following two cardiac markers?

Question

Quizplus · Accepted Answer

The combination of myoglobin and cardiac troponins is the best choice of markers for acute MI.With these two markers,elevations (supporting diagnosis of an MI),are seen over a 2- to 10-day window of time.Homocysteine and CRP are both compounds determined to be risk factors,predicting increased likelihood of acute MI.Both CK-MB and LDH are enzymes,once utilized as markers of an acute coronary event.Today,the increased specificity of troponins,combined with early detection of the muscle protein myoglobin,is the preferred combination of cardiac markers.
