Jiang L, et al. - Given previous studies have suggested that myocardial bridge (MB; generally described as a congenital benign variation) prevents atherosclerotic plaques from accumulating within the bridge segment, but promotes coronary stenosis in the proximal segment adjacent to MB, researchers investigated the impacts of MB on severe obstructive atherosclerosis in the whole coronary artery system. They found that, in patients with MB vs patients without MB, there was a much lower rate of severe obstructive coronary artery disease (SOCAD) requiring percutaneous coronary intervention or coronary artery bypass grafting. Overall, findings indicated that MB might be a protective factor against severe obstructive atherosclerosis in the whole coronary artery system.
