Answer:
Option E, nitroglycerin
Explanation:
The antianginal medication nitroglycerin treats coronary artery disease by dilating the coronary arteries to improve the blood flow. Doing so reduces the blood pressure as well as the oxygen demand by the myocardium.
Prophylactic usage of nitroglycerin can prevent angina pectoris; immediate use following an anginal attack can provide pain relief.
Therefore, the vasodilation medication prescribed for coronary artery disease and angina prophylaxis is nitroglycerin, option E.
