  • Title: Coronary artery spasm. What is its role in ischemic heart disease?
    Author: Chahine RA.
    Journal: Postgrad Med; 1986 Mar; 79(4):78-81, 85-91. PubMed ID: 2869479.
    Abstract:
    Knowledge of the pathophysiology of myocardial ischemia has been greatly enhanced recently by new information on coronary artery spasm. This phenomenon accounts for the mechanism underlying the attacks of resting chest pain in Prinzmetal's angina and plays a role in almost all aspects of ischemic heart disease. The diagnosis of coronary artery spasm can be made presumptively with noninvasive methods, but definitive documentation is usually obtained in the cardiac catheterization laboratory. The nitrate derivatives and the calcium antagonists provide a safe and effective approach to therapy.
