Atavism is the rare reappearance, in a modern organism, of a trait from a distant evolutionary ancestor. We describe an apparent case of atavism involving a 59-year-old man with chest pain whose coronary circulation and myocardial architecture resembled those of the reptilian heart. The chest pain was attributed to a coronary steal phenomenon. The patient was discharged from the hospital on a heightened regimen of β-blockers, and his symptoms improved significantly. To our knowledge, this is only the 2nd reported clinical case of a human coronary circulation similar to that of reptiles.
返祖现象是指在现代生物体中罕见地重新出现遥远进化祖先的一种性状。我们描述了一个明显的返祖病例，涉及一名59岁胸痛男子，其冠状动脉循环和心肌结构类似于爬行动物的心脏。胸痛归因于冠状动脉窃血现象。患者出院时服用强化的β受体阻滞剂方案，其症状显著改善。据我们所知，这是第二例报道的人类冠状动脉循环类似于爬行动物的临床病例。
