A patient is taking a calcium channel blocker (CCB) for stable angina. The patient's spouse asks how calcium channel blockers relieve pain. The nurse will explain that CCBs:
a. help relax peripheral arterioles to reduce afterload.
b. improve coronary artery perfusion.
c. increase the heart rate to improve myo-cardial contractility.
d. increase the QT interval.
A
CCBs promote relaxation of peripheral arterioles, resulting in a decrease in afterload, which re-duces the cardiac oxygen demand. CCBs do not improve coronary artery perfusion. CCBs reduce the heart rate and suppress contractility; they do not affect the QT interval.
