[Detection rate of myocardial bridge in coronary angiography and its clinical significance].
OBJECTIVE
To explore the detection rate of myocardial bridge (MB) in coronary angiography and its clinical significance.


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


RESULTS
MB 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 ).


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