摘要
Nausea and vomiting occur frequently in patients with acute myocardial infarction （AMI）. To determine whether the incidence of nausea and vomiting in patients with AMI varies with infarct location, the authors studied 80 patients who had been admitted to the hospital for ST-segment elevation AMI. Data were prospectively collected from patients with AMI and nausea or vomiting for one year. Patients were enrolled if the diagnosis of AMI with nausea or vomiting is retained. The infarct location （i.e., inferior vs. anterior） in the patients with STEMI was determined using the established World Health Organization electrocardiographic criteria. Of the 80 patients included, nausea was reported in 44 patients （55%） and vomiting in 36 patients （45%）. The mean age was 58, 1 ± 11, 8 years old, and males comprised 62 patients （77.5%）. Inferior AMI was present in 47 patients （58.8%） and anterior AMI in 33 patients （41.2%）. The peak serum troponin I concentrations was significantly greater in those with anterior AMI than in those with inferior AMI respectively 0.52 ± 0.28 ng/mL and 0.50 ± 0.34 ng/mL. In conclusion, nausea and vomiting are common presenting symptoms in patients with either inferior or anterior wall AMI, but their frequency is unrelated to the infarct location.
