Abstract:
Objective Myocardial bridging is a congenital anomaly.However,little data is available for patients with myocardial bridging (MB) associated with acute myocardial infarction (AMI).The goals of this study are to evaluate characteristics of MB in patients with AMI.Methods From March 1999 to February 2006,137 patients with both MB and AMI,were identified by coronary angiography,including 117 men and 20 women with an average age of 60.77±12.01 years (range 30-83 years) were enrolled in the present study.Results There were 119 patients with MB at the middle segment of left anterior descending artery (LAD),15 patients at distal segment of LAD,2 patients at middle segment of left circumflex (LCX),and 1 at the proximal segment of the obtuse marginal branch (OM) of LCX.There are 36 patients with non-ST elevation acute myocardial infarction (NSTEAMI),38 patients with anterior ST elevation AMI (STEAMI),40 patients with inferior STEAMI and 23 patients with inferior-posterior STEAMI.Risk factors such as hypertension,diabetes,hyperlipidemia and smoking were not different among four groups.Patients with anterior AMI included 8 patients who showed no stenosis at the segment of MB.Conclusion Patients with MB and ST elevation AMI were mainly inferior AMI.MB might be one of the causes of AMI.
