Review of 1,900 cineangiograms revealed myocardial bridging in 15 patients. 6 patients with more than 75% systolic narrowing in LAD, no evidence of significant atherosclerotic coronary disease, and normal ventricular wall motion underwent further investigation which included clinical examination, ECG and exercise test. All patients suffered from uncharacteristic chest pain. Abnormal ECG showed no specific changes of ST segment. In 4 patients an exercise was positive. All investigated patients were treated with nifedipine. After 6 month therapy myocardial perfusion was evaluated by exercise radionuclide Th-201 myocardial scintigraphy. Normal perfusion was stated in 2 patients. In 4 others perfusion deficits were observed in LAD distribution. Exercise test repeated during therapy was positive in 2 of cases. Chest pain was less severe in all treated patients and Ecg became normal in 2 of them.
对1900份心血管造影照片的回顾显示，15例患者存在心肌桥。6例左前降支收缩期狭窄超过75%、无明显动脉粥样硬化性冠状动脉疾病证据且心室壁运动正常的患者接受了进一步检查，包括临床检查、心电图和运动试验。所有患者均有非典型胸痛。心电图异常未显示ST段有特异性改变。4例患者运动试验呈阳性。所有接受调查的患者均接受硝苯地平治疗。治疗6个月后，通过运动放射性核素铊-201心肌闪烁显像评估心肌灌注。2例患者灌注正常。另外4例在左前降支分布区域观察到灌注缺损。治疗期间重复进行的运动试验在2例患者中呈阳性。所有接受治疗的患者胸痛减轻，其中2例患者心电图恢复正常。
