Is myocardial bridging associated with coronary endothelial dysfunction in patients with chest pain and non-obstructive coronary artery disease?
Myocardial bridging is associated with both epicardial and microvascular endothelial dysfunction, suggesting it as a potential mechanism for angina in patients with non-obstructive CAD.
MB co-localises with epicardial endothelial dysfunction and is significantly associated with microvascular endothelial dysfunction in symptomatic patients with non-obstructive CAD, supporting its potential role as a mechanism for angina in symptomatic patients with MB.
