ST elevation combined with typical chest pain is an indication for acute coronary vascularization and is usually associated with acute myocardial infarction. Herein, we present an unusual case of ST elevation.
A 57-year-old male patient presented to the emergency department with chest pain radiating to both arms and the back. Typical clinical presentation and inferolateral ST elevations were suggestive of ST elevation myocardial infarction. Interestingly, coronary occlusion was excluded by coronary angiography. Despite extensive diagnostic workup, no underlying diagnosis was made. Four days later, the patient returned and reported pain in the right upper abdomen. Clinical presentation, laboratory analysis, and imaging features led to a diagnosis of calculous acute cholecystitis. Laparoscopic cholecystectomy was performed, and the diagnosis was confirmed. Electrocardiographic changes and pain resolved completely.
Acute calculous cholecystitis is initiated by gallbladder distension due to biliary duct occlusion caused by gallstones. ST elevations in response to gallbladder distension have been demonstrated in animal models. We hypothesize that the ST elevations observed in this patient with chest pain were linked to stone-mediated distension of the gallbladder, leading to reflex coronary vasoconstriction.
ST段抬高合并典型胸痛是急性冠状动脉血管重建的指征,通常与急性心肌梗死相关。在此,我们报告一例不寻常的ST段抬高病例。
一名57岁男性患者因胸痛放射至双臂及背部就诊于急诊科。典型的临床表现及下壁导联ST段抬高提示ST段抬高型心肌梗死。有趣的是,冠状动脉造影排除了冠状动脉闭塞。尽管进行了广泛的诊断检查,仍未明确潜在病因。四天后,患者复诊,诉右上腹疼痛。临床表现、实验室分析及影像学特征确诊为结石性急性胆囊炎。行腹腔镜胆囊切除术,确诊得到证实。心电图改变及疼痛完全缓解。
急性结石性胆囊炎由胆结石阻塞胆管导致胆囊扩张引发。动物模型已证实胆囊扩张可导致ST段抬高。我们推测该胸痛患者出现的ST段抬高与结石介导的胆囊扩张有关,进而导致反射性冠状动脉收缩。
