Variant angina attacks are effectively treated with short-acting nitrates. Calcium channel blockers and nitrates are the primary treatments for coronary artery spasm, improving outcomes in most patients.

Area of Science:

  • Cardiology
  • Pharmacology

Background:

  • Variant angina, or vasospastic angina, is characterized by coronary artery spasm.
  • Specific receptor blockade has proven unsatisfactory for preventing ischemic attacks.

Purpose of the Study:

  • To review the pharmacologic management of variant angina.
  • To highlight the efficacy of vasodilators, particularly calcium channel blockers and nitrates.

Main Methods:

  • Review of existing literature on variant angina treatment.
  • Analysis of the mechanisms of action for various pharmacologic agents.

Main Results:

  • Short-acting nitrates provide prompt relief for variant angina attacks.
  • Calcium channel blockers and nitrates are the mainstay for managing coronary artery spasm, controlling attacks in up to 80% of patients.

  • Calcium antagonists have shown significant improvement in clinical outcomes for variant angina.

    • Conclusions:

    • Nonspecific vasodilators, primarily calcium channel blockers and nitrates, are the most effective treatment for vasospastic angina.
    • Further research into the causes of coronary smooth muscle hyperreactivity is needed.
    • Current pharmacologic strategies effectively manage recurrent ischemic attacks and improve patient outcomes.
