急性心肌梗塞患者多数伴有胃肠道症状或伴发胃肠道疾病。剧烈疼痛是一个危险信号,因为疼痛参与内脏一内脏反射机制,能诱发某些病理综合征,如胃肠综合征。因此,急性心肌梗塞发病早期,特别是疼痛剧烈时,常发生恶心、呕吐、腹痛、腹张,食欲减退,其发生可能是心肌病变刺激引起迷走神经对胃肠反射性作用的结果。在疼痛波及或主要位于上腹部的病人,易误诊为急性胃炎,肝、胆疾病或其它急腹症,延误了心肌梗塞的诊断及治疗,甚至危及生命。因此,临床遇到上腹痛、恶心、呕吐的中老年病人时,应想到有心肌梗塞的
Most patients with acute myocardial infarction associated with gastrointestinal symptoms or gastrointestinal diseases. Severe pain is a dangerous signal because pain is involved in visceral-visceral reflex mechanisms that can induce certain pathological syndromes such as gastrointestinal syndromes. Therefore, the early onset of acute myocardial infarction, especially when the pain is severe, often nausea, vomiting, abdominal pain, abdominal distention, loss of appetite, its occurrence may be caused by myocardial lesions stimulate the vagus nerve gastrointestinal reflex action. In patients with pain or mainly in the upper abdomen, misdiagnosed as acute gastritis, liver, gallbladder disease or other acute abdomen, delayed the diagnosis and treatment of myocardial infarction, and even life-threatening. Therefore, the clinical encounter upper abdominal pain, nausea, vomiting in the elderly patients, should think of myocardial infarction
