    Coronary artery spasm causes chest pain and mimics heart attacks on ECGs. Diagnosis is confirmed with ergonovine testing, and treatment primarily involves nitrates and calcium channel blockers.

    Area of Science:

    • Cardiology
    • Vascular Medicine

    Background:

    • Coronary artery spasm is a cardiovascular condition.
    • It can occur independently of or alongside atherosclerosis.
    • Spasm can present with symptoms mimicking acute myocardial injury.

    Purpose of the Study:

    • To describe the syndrome of coronary artery spasm.
    • To outline diagnostic methods and therapeutic strategies.

    Main Methods:

    • Review of the syndrome of coronary artery spasm.
    • Description of diagnostic testing using intravenous ergonovine.
    • Discussion of therapeutic options.

    Main Results:

    • ECG changes during spasm resemble myocardial injury but typically normalize post-pain.

  • Intravenous ergonovine is a sensitive and specific diagnostic tool.
  • Nitrates and calcium channel blockers are primary treatments.

    • Conclusions:

    • Coronary artery spasm is a distinct clinical entity.
    • Ergonovine testing reliably confirms the diagnosis.
    • Pharmacological management is effective, while surgical roles require further clarification.
