Key result
Myocardial bridging was significantly more common in vasospastic angina patients with chest symptoms during exercise compared to those with symptoms only at rest (50% vs 12%, p=0.0002).
Why the study?

Myocardial bridging was associated with exertional symptoms in vasospastic angina; hypothesis-generating cross-sectional link requiring prospective confirmation.
Teragawa et al. (2017) conducted an observational in Vasospastic angina (n=101). Chest symptoms during exercise vs. Chest symptoms only at rest was evaluated on Presence of myocardial bridging (p=0.0002). Myocardial bridging was significantly more common in vasospastic angina patients with chest symptoms during exercise compared to those with symptoms only at rest (50% vs 12%, p=0.0002).
