MYOCARDIAL BRIDGE MUSCLE INDEX (MMI): A MARKER OF DISEASE SEVERITY AND ITS RELATIONSHIP WITH ENDOTHELIAL DYSFUNCTION AND SYMPTOMATIC OUTCOME IN PATIENTS WITH ANGINA AND A HEMODYNAMICALLY SIGNIFICANT MYOCARDIAL BRIDGE

Myocardial bridge (MB) muscle index (MMI), the product of MB depth x length, is suggestive of severity of an MB. MBs are also associated with endothelial dysfunction. We studied the relationship of MMI with endothelial function, and its effect on symptomatic outcome in patients undergoing surgical
