6. Which of the following is the mechanism of action of nitrates?
a. Decrease the responsiveness of heart to the sympathetic nervous system
b. Lower the heart rate
c. Decrease cardiac contractility
d. Dilation of coronary arteries
✓ ~~> 6. D: Nitrates are useful for the prevention and treatment of
angina. They work by dilating the coronary arteries and thus increasing
the blood flow to the heart. They dilate peripheral veins, and, in higher
doses, other peripheral arteries, which decreases preload and
afterload. Beta-blockers decrease the responsiveness of the heart to
the sympathetic nervous system. Calcium channel blockers, beta-
blockers, and other medications decrease cardiac contractility and
decrease heart rate.
