Question 5 of 5
All these drug groups useful in angina both decrease myocardial oxygen requirement (by decreasing the determinations of oxygen demand) and increase myocardial oxygen delivery (by reversing coronary arterial spasm), EXCEPT:
Correct Answer: C
Rationale: Nitrates and calcium channel blockers reduce oxygen demand (via preload/afterload reduction) and increase oxygen delivery (via vasodilation/spasm relief). Beta-blockers reduce oxygen demand (via decreased heart rate and contractility) but do not reverse coronary spasm. Potassium channel openers like Minoxidil are vasodilators but are not primarily used in angina.
