Prinzmetal variant angina is characterized by episodic chest pain associated with transient ST changes seen on an electrocardiogram (EKG). A 51-year-old female with a pertinent history of non-obstructive coronary artery disease (CAD), non-ST elevation myocardial infarction (NSTEMI) twice, ST-elevation myocardial infarction (STEMI), Prinzmetal angina, ventricular tachycardia s/p implantable cardioverter-defibrillator placement, and gastroesophageal reflux disease presented with 2.5 hours of left-sided chest pain with radiation to the left arm. Her initial EKG was not revealing. However, a subsequent EKG showed ST elevations in the inferior leads. A coronary angiogram was performed and revealed distal right coronary artery spasm that was relieved with intracoronary nitroglycerin. The nature of her chest pain in conjunction with her EKG and angiogram findings helped diagnose her with Prinzmetal angina that was significant enough to result in a STEMI. Thus, Prinzmetal angina and STEMI can be interconnected rather than being separate, mutually exclusive pathologies.
变异型心绞痛的特征是发作性胸痛,并伴有心电图(EKG)上可见的短暂ST段改变。一名51岁女性,有非阻塞性冠状动脉疾病(CAD)、两次非ST段抬高型心肌梗死(NSTEMI)、ST段抬高型心肌梗死(STEMI)、变异型心绞痛、植入式心脏复律除颤器置入术后室性心动过速以及胃食管反流病病史,因左侧胸痛2.5小时并向左臂放射而就诊。她最初的心电图未发现异常。然而,随后的心电图显示下壁导联ST段抬高。进行了冠状动脉造影,显示右冠状动脉远端痉挛,经冠状动脉内硝酸甘油治疗后缓解。她胸痛的性质以及心电图和血管造影结果有助于诊断她患有变异型心绞痛,严重到足以导致STEMI。因此,变异型心绞痛和STEMI可能相互关联,而不是相互独立、互斥的病理状态。
