Question

Quizplus · Accepted Answer

Variant angina occurs when coronary arteries go into spasm,thus reducing the circulation and oxygen supply to the heart. CCBs help to reduce coronary artery spasm; beta blockers do not. Beta₁-selective beta blockers are used for stable angina for patients who also have asthma,because they do not activate beta₂ receptors in the lungs to cause bronchoconstriction. Beta blockers help improve the oxygen supply in stable angina,but they do not relieve coronary artery spasm,so they are not useful in variant angina. Beta blockers do not constrict arterial smooth muscle.
