Which type of angina is Calcium channel blockers preferred for?

  1. Stable angina

  2. Prinzmetal's angina

  3. Unstable angina

  4. Microvascular angina

The correct answer is: Prinzmetal's angina

Calcium channel blockers are used to relax and widen the blood vessels, which can help alleviate spasms in the coronary arteries. This type of medication is most effective for treating Prinzmetal's angina, which is characterized by spasms in the coronary arteries. Stable angina typically does not involve spasms and is often treated with other medications like beta blockers or nitrates. Unstable angina is a more serious condition that may require more immediate treatment with procedures like angioplasty. Microvascular angina is a form of angina that does not involve blockages in the larger coronary arteries and may not respond to calcium channel blockers. Therefore, calcium channel blockers are preferred for Prinzmetal's angina but may not be the best choice for the other types of angina.
