Abstract:
Objective To investigate the methods and efficacy of coronary stent placement in patients with myocardial bridge. Methods 4 patients with angina and ST-T changes in ECG were involved in the study. Coronary angiography showed there were 75%～90% systolic stenosis of LAD in all patients. Two of them were regarded as isolated myocardial bridge, and the others were regarded as myocardial bridge associated with atherosclerosis. The length of artery pressed by myocardial bridge was in the range of 10～18 mm. All patients who had repeated angina accepted stenting therapy. One of the stents was Crossflex, three were Nir stents. Stents size: (3.0～3.5)?(12～20)mm. All stents were expanded with 8～10 atm for 30～40 seconds. Results After stenting, coronary angiography showed no residual stenosis. In the follow-up 6～18 months there were no complaints of angina. In two of them, coronary angiography showed there were no restenosis after one year.Conclusion Coronary stenting is an optional method to treat patient who have myocardial bridge and have no efficacy after taking medicines, especially for the patients who have both myocardial bridge and atherosclersis. But futher study in large populations is still necessary.
