Rationale 1: The primary means by which antianginal drugs terminate an acute angina episode, or decrease the frequency of angina episodes, is by reducing the myocardial demand for oxygen.
Rationale 2: Antianginal medications do not have an anticoagulant effect.
Rationale 3: Antianginal medications cannot increase the oxygen supply to the myocardium.
Rationale 4: Antianginal medications do not increase nitric acid production.
