title: Bridge over troubling spasm: is the association of myocardial bridging and coronary artery spasm a distinct entity? Three case reports.
abstract: The association of coronary artery spasm and myocardial bridging is very uncommon and may represent a distinct clinical entity. Three patients are described, presenting with acute coronary syndrome associated with myocardial bridging and coronary artery spasm. The relationship and respective roles of myocardial bridging and spasm, however, remain uncertain and may be consequent to a direct effect on endothelial function from the compressive effect of myocardial bridging. The role of intracoronary nitroglycerin in these patients is unresolved.
