[Muscle bridge and myocardial ischemia. Study of 6 cases].
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.
