    Area of Science:

    • Cardiology
    • Pathophysiology

    Background:

    • Coronary artery spasm is a key factor in myocardial ischemic diseases.
    • Potential causes include autonomic nervous system activity, prostaglandins, and calcium availability.

    Purpose of the Study:

    • To outline the role of coronary artery spasm in myocardial ischemia.
    • To detail diagnostic and therapeutic strategies for coronary artery spasm.

    Main Methods:

    • Review of existing literature on coronary artery spasm.
    • Analysis of diagnostic criteria and treatment modalities.

    Main Results:

    • Coronary artery spasm leads to myocardial ischemia, chest pain, and ECG/hemodynamic changes.
    • It is the primary mechanism in Prinzmetal's variant angina and associated with other ischemic syndromes.
  • Coronary angiography is the definitive diagnostic tool.

    • Conclusions:

    • Coronary artery spasm is a significant cause of ischemic heart disease.
    • Effective treatments include nitrates and slow-channel blockers like verapamil and nifedipine.
