Sample item

What is the main antianginal effect of nitrates?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Reduce preload by venodilation

Nitrates predominantly dilate veins, lowering venous return and ventricular wall stress, which reduces myocardial oxygen demand in angina.

Option by option

  • A. Cause bronchoconstriction

    Bronchoconstriction is not their therapeutic effect.

  • B. Reduce preload by venodilation (correct)

    Correct: venodilation reduces preload and oxygen demand.

  • C. Increase platelet aggregation

    Nitrates do not increase platelet aggregation.

  • D. Raise afterload

    They tend to reduce rather than raise afterload at higher doses.
