Coronary artery anomalies are relatively uncommon in the general population with a roughly 1% incidence. Though oftentimes asymptomatic, these anomalies can be detrimental, resulting in myocardial infarction and even sudden cardiac death. Here, we present a case in which a 65-year-old male presented to the emergency room with substernal chest pain that radiated into his left arm. The patient's cardiac enzyme panel revealed a troponin of 10.14 ng/mL and a creatine kinase-myocardial band (CK-MB) of 78.8 ng/mL. Furthermore, the patient's electrocardiogram demonstrated normal sinus rhythm with no significant changes. Upon cardiac catheterization, his right coronary artery was found to originate from the left coronary cusp. Moreover, the anomalous artery demonstrated significant stenosis in its middle portion, which was presumably causing his elevated cardiac enzymes and anginal chest pain. The patient underwent successful percutaneous coronary intervention and was discharged the following day.
冠状动脉异常在普通人群中相对不常见，发病率约为1%。尽管这些异常情况通常无症状，但可能有害，导致心肌梗死甚至心源性猝死。在此，我们报告一例病例，一名65岁男性因胸骨后胸痛放射至左臂而就诊于急诊室。患者的心肌酶谱显示肌钙蛋白为10.14 ng/mL，肌酸激酶同工酶（CK-MB）为78.8 ng/mL。此外，患者的心电图显示窦性心律正常，无明显变化。心脏导管检查发现其右冠状动脉起源于左冠状动脉窦。此外，异常动脉在其中段显示出明显狭窄，推测这是导致其心肌酶升高和心绞痛性胸痛的原因。患者接受了成功的经皮冠状动脉介入治疗，并于次日出院。
