Objective : To investigate the characteristics of myocardial bridging of coronary angiography and coronary atherosclerosis relationship . Methods: June 2008 - March 2010 on suspicion of coronary artery disease and in between my hospital undergoing coronary angiography Cardiology 1461 patients underwent coronary angiography for 1461 (CAG) examination were retrospectively examined analysis, based on angiography showed coronary artery luminal stenosis determined systolic myocardial bridge . Results: In 1461 a routine elective coronary angiography populations were detected 126 cases of myocardial bridge , the detection rate of 8.42% . Occurred mainly in the left anterior descending artery ( 99.2% ) . 25 cases ( 19.84% ) in the myocardial bridge proximal atherosclerosis , myocardial bridge proximal coronary artery stenosis was significantly higher than that covered coronary myocardial bridge ( ie, coronary artery wall ) and distal coronary artery ; Noble three patients prone to tightness or chest pain ( 96.3% ) .52 cases of ischemic electrocardiographic ST-T changes , accounting for 41.26% . Noble graded as increased myocardial bridge myocardial bridge proximal incidence of coronary artery stenosis increasing trend (P lt; 0.05), and blood glucose , blood lipids , blood pressure, age, gender, body mass index, ejection fraction irrelevant . Conclusion: Coronary angiography in the diagnosis of myocardial bridge detection rate . Myocardial ischemia and Noble grading . Myocardial bridge luminal stenosis and systolic blood sugar , blood lipids , blood pressure, age, gender, body mass index, ejection fraction irrelevant . Muscle before the bridge prone to atherosclerosis , and with systolic blood pressure , left ventricular hypertrophy , Noble grading .
