Nitrates are commonly used antianginal drugs that act to: a. increase the preload on the heart. b. increase the afterload on the heart. c. dilate coronary vessels to increase the delivery of oxygen through those vessels. d. decrease venous return to the heart, decreasing the myocardial workload. 4. Calcium channel blockers are effective in treating angina because they: a. prevent any cardiovascular exercise, preventing strain on the heart. b. block strong muscle contractions, causing vasodilation. c. alter the electrolyte balance of the heart, preventing arrhythmias. d. increase the heart rate, making it more efficient.
