Abstract
Anomalous origin of right coronary artery (RCA) has been associated with angina, myocardial infarction and sudden death. Often these patients are referred for surgery. However, long-term β-blocker therapy instead of surgery has been used in some cases with success. The authors report a case of anomalous RCA where resolution of ischemia with β-blocker was objectively demonstrated on serial stress testing.
摘要
右冠状动脉（RCA）异常起源与心绞痛、心肌梗死及猝死相关。这些患者常被转诊接受手术治疗。然而，在某些情况下，长期使用β受体阻滞剂治疗而非手术治疗也取得了成功。作者报告了一例RCA异常的病例，通过连续的负荷试验客观地证明了β受体阻滞剂可缓解心肌缺血。
