Answer 1

Answer: To decrease workload of the heart

Step-by-step explanation:

Beta-adrenergic blocking agents are drugs that functions by reducing the pressure of the blood, opening up of the veins and arteries to aid in proper flow of blood on the vessels thus causing the heart to beat slowly. They work by blocking the effects of ephinephrine; the fight and flight hormone in order to stabilize and lower coronary artery disease.

Beta-adrenergic blockers as the name implies block the effects of increased adrenergic activity which results from cardial dysfunction.
