Question

Quizplus · Accepted Answer

Reducing oxygen demand may be effective in preserving myocardial muscle.Decreasing demand increases myocardial oxygen supply.Once the cardiac muscle has been damaged,it is more important to preserve remaining muscle and prevent further loss of the myocardium.Reduction in the heart rate and blood pressure is not the primary treatment goal in MI care.Parasympathetic activation is not the primary treatment for myocardial infarction.
