Coronary ArteryCoronary artery disease is caused by arteriosclerosis or the hardening of the arteries and/or atherosclerosis, the narrowing of the arteries, which results from the accumulation and hardening of fat deposits called plaque.

Medications

Medications may be necessary to help the heart regain its function, according to Cleveland Clinic. As per the publication, nitroglycerin serves as the most common vasodilator used for acute angina cases. It increases the opening of the blood vessels to enhance the blood flow and oxygen delivery to the heart muscles, decreasing the workload of the heart. Other medications prescribed for the heart disease are ACE inhibitors to reduce the heart workload, beta blockers to relax the blood vessels and slow the heart rate, anti-coagulants like aspirin to prevent blood clots, and anti-lipidemic agents to control the high blood cholesterol levels.
