Among 7467 consecutive coronary angiograms performed during an 8-year period, 61 patients had a myocardial bridge of the left anterior descending coronary artery. The overall prevalence of myocardial bridges was 0.82% (from 0.41% to 1.16% per year). Among these patients, 26 had coronary artery disease, 4 had valvular heart disease, and 3 had cardiomyopathy. We studied the long-term outcome (11 +/- 3 years) of the other 28 patients with isolated milking at baseline. Two groups were constituted according to the percentage of systolic reduction of the left anterior descending coronary artery lumen: group A, < 50% (15 patients) and group B, > or = 50% (13 patients). During follow-up, 1 group A patient (cancer) and 2 group B patients (1 cancer and 1 suicide) died. Moreover, 1 group B patient was lost to follow-up. None of the patients sustained a myocardial infarction during follow-up. In group A patients, 71% felt very well or well and 50% had clinical symptoms; 64% took antianginal medications. In group B patients, 50% felt well and 70% had clinical symptoms; 50% took antianginal drugs. The long-term prognosis of isolated myocardial bridges of the left anterior descending coronary artery is good and is independent of the severity of systolic narrowing of internal lumen diameter.
在8年期间进行的7467例连续冠状动脉造影中，61例患者存在左前降支冠状动脉心肌桥。心肌桥的总体患病率为0.82%（每年0.41%至1.16%）。在这些患者中，26例患有冠状动脉疾病，4例患有心脏瓣膜病，3例患有心肌病。我们研究了另外28例基线时单纯存在压榨现象患者的长期预后（11±3年）。根据左前降支冠状动脉管腔收缩期狭窄百分比分为两组：A组，<50%（15例患者）和B组，≥50%（13例患者）。随访期间，A组1例患者（癌症）和B组2例患者（1例癌症和1例自杀）死亡。此外，B组1例患者失访。随访期间无患者发生心肌梗死。A组患者中，71%感觉非常好或良好，50%有临床症状；64%服用抗心绞痛药物。B组患者中，50%感觉良好，70%有临床症状；50%服用抗心绞痛药物。左前降支冠状动脉单纯心肌桥的长期预后良好，且与管腔内收缩期狭窄的严重程度无关。
