Ischemic heart disease is the leading cause of death in the United States and the world. Advanced age is the strongest risk factor for ischemic heart disease and the best independent predictor for poor outcomes after acute coronary syndrome (ACS). Elderly patients are at high risk for ACS, and numerous studies have shown that octogenarians in particular experience increased morbidity and mortality compared to younger patients.
We describe a case of an 83-year-old woman who presented to the emergency department with a chief complaint of sore throat and was found to have a non-ST elevation myocardial infarction (NSTEMI) and was treated successfully with primary coronary intervention (PCI). WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Chest pain is a common presenting symptom for ACS, but elderly patients with MI are more likely to present with other chief complaints. Only 40% of patients in the National Registry of Myocardial Infarction database ≥ 85 years of age had chest pain on initial presentation. Recent studies comparing invasive therapy (PCI or coronary artery bypass graft) with optimal medical therapy for patients > 75 years of age diagnosed with NSTEMI have reported a reduced risk of death and major cardiac events with invasive therapy. Emergency physicians should have a high level of suspicion for ACS in octogenarians, even in those presenting without chest pain. Timely diagnosis and management can improve morbidity and mortality in these patients.
缺血性心脏病是美国和全球的主要死因。高龄是缺血性心脏病最强的危险因素,也是急性冠状动脉综合征(ACS)后不良预后的最佳独立预测因素。老年患者发生ACS的风险很高,大量研究表明,尤其是八旬老人与年轻患者相比,发病率和死亡率更高。
我们描述了一例83岁女性患者,因咽痛为主诉就诊于急诊科,被诊断为非ST段抬高型心肌梗死(NSTEMI),并通过急诊冠状动脉介入治疗(PCI)成功治愈。急诊医生为何应了解此病例?胸痛是ACS常见的就诊症状,但老年心肌梗死患者更可能以其他主诉就诊。在国家心肌梗死注册数据库中,≥85岁的患者中只有40%在初次就诊时有胸痛症状。最近的研究比较了年龄>75岁的NSTEMI患者的侵入性治疗(PCI或冠状动脉搭桥术)与最佳药物治疗,结果显示侵入性治疗可降低死亡风险和主要心脏事件的发生风险。急诊医生应高度怀疑八旬老人患有ACS,即使是那些没有胸痛症状的患者。及时诊断和治疗可改善这些患者的发病率和死亡率。
