ABSTRACT
Background:An anatomical anomaly in which myocardial fibers make the bridge over the epicardial coro- nary artery is called ‘ myocardial bridge’ . Its clinical significance has been emphasized, because some serious cardiac diseases such as myocardial infarction or sudden cardiac death can be developed. Methods:Forty five patients (30 male and 15 female, 48±11.0 years) out of 4,694 patients who underwent diagnostic coronary angiography and diagnosed as myocardial bridge at Chonnam National University Hospital between January 1996 and March 1999, were analyzed retrospectively. Results:The incidence of myocardial bridge on the coronary angiography was 0.95%. Middle left anterior descending artery was most common (36 patients, 80%) in the location. Associated stenoses were observed in 5 cases (11.1%). For the pharmacological treat- ment, calcium antagonist (26 cases, 57.7%), β-blocker (23 cases, 51.1%) and nitrate (9 cases, 20.0%) were used. Single regimen was used in 30 (66.7%) cases, dual drugs were administered in 11 (24.4%) and triple drugs in 2 (4.4%) cases. During clinical follow-up of 40 patients for 14±11 months (4-40 months), no major cardiac events developed in all patients. Conclusion:The incidence of the myocardial bridge is 0.95% and middle left anterior descending artery was the most common site. Long-term prognosis is relatively good in almost patients with myocardial bridge. ((((Korean Circulation J 2000;30((((7)))):819-826))))

관상동맥 심근교란 정상적으로 심외막에 위치하는
관동맥의 일부에 심근섬유가 over-bridging을 이루고 있는 해부학적 형태 이상을 말한다. 임상적으로는 관상 동맥 조영술상의 범주로서, 관상동맥의 직경이 수축기 동안에 심근수축에 의해 좁아지는 상태를 지칭한다. 이
