OBJECTIVETo explore the detection rate of myocardial bridge (MB) in coronary angiography and its clinical significance.

METHODThe clinical data of 2 165 cases who had received selective coronary angiography were studied retrospectively.

RESULTSMB was detected in 66 patients (3. 0% ) , among whom 62 were found in left anterior descending artery. Among the 58 cases with isolated myocardial bridge, 24 had no remarkable symptoms, whereas 34 showed clinical symptoms such as angina. The arterial stenosis beneath MB was significantly correlated with clinical symptoms (P < 0. 05 ).

CONCLUSIONThe improvement of the detection rate of MB can effectively decrease misdiagnosis and benefit the treatment.
