The authors analyse the clinical and therapeutic aspects of myocardial bridges in a series of 6 male patients between the ages of 41 and 61 years. In every cases, the presenting signs were ischaemic order: one myocardial infarction, three cases of unstable angina and two case of stable angina. On coronary angiography, these muscle bridges involved the left anterior descending artery in all cases. The causal relationships between muscle bridges and myocardial ischaemia are discussed. Among the various factors incriminated, spasm, tachycardia and thrombosis appear to play an important role. Depending on the case, treatment modalities consist of beta-blockers, platelet antiaggregants and calcium channel blockers. Surgical treatment is reserved for patients who remain symptomatic despite medical treatment.
作者分析了6例年龄在41至61岁之间男性患者心肌桥的临床和治疗方面情况。在所有病例中，呈现的症状均为缺血性病症：1例心肌梗死、3例不稳定型心绞痛和2例稳定型心绞痛。在冠状动脉造影检查中，所有病例的这些肌桥均累及左前降支动脉。文中讨论了肌桥与心肌缺血之间的因果关系。在诸多被认为有影响的因素中，痉挛、心动过速和血栓形成似乎起着重要作用。根据具体病例，治疗方式包括使用β受体阻滞剂、血小板抗聚集剂和钙通道阻滞剂。手术治疗仅适用于尽管接受了药物治疗仍有症状的患者。
