Is MCG useful for screening asymptomatic patients?
Yes — A large number of patients with clinically significant coronary artery obstruction remain asymptomatic up until their first heart attack — at this point it is too late to reverse the damage done to the heart. Because of its high positive and negative predictive values, MCG is an excellent first-line screening tool prior to using more invasive techniques such as coronary angiography. Evaluation with the MCG system can detect coronary disease in its earliest stages, allowing intervention before damage is done. If testing reveals early-stage CAD lifestyle changes and medication may be all that is necessary to avoid a potentially life-threatening heart attack. For more advanced disease progression an MCG evaluation may provide the first indication of coronary ischemia and enable intervention prior to a life-threatening coronary event.
