Abstract：investigate the incidence of non-ischemic changes in patients with non-ST-segment elevation acute myocardial infarction (NSTEMI) and its impact on prognosis. Methods From January 2014 to December 2017, 192 patients with NSTEMI who were admitted to the Department of Cardiology of Danyang People's Hospital were divided into no ischemia group and ST group depression group according to the 12 or 18 lead electrocardiogram in the emergency department. The incidence of non-ischemic changes in the electrocardiogram of patients with NSTEMI, the incidence of cardiovascular composite endpoints during hospitalization and 30 days of discharge were recorded. Results Compared with the ST-segment depression group, the non-ischemic change group was lighter in age, had a recent history of smoking, and had fewer cardiovascular risk factors. There was no ischemic change group (n=110, 57.3%), and the incidence was significantly higher than that of the ST segment depression group (n=82, 42.7%). The incidence of 3-vessel disease in the non-ischemic change group was lower than that in the ST-segment depression group (28.2% vs. 41.5%, P=0.003), left main (7.3% vs. 24.4%, P=0.000) and proximal anterior descending The incidence of lesions (30.9% vs. 41.5%, P=0.027) was lower than that in the ST-segment depression group, and the D-to-B time (h) in the no-ischemia group was significantly higher than that in the ST-segment depression group ((30.88±18.29) vs. (14.61 ± 6.25), P=0.000). The MACE during hospitalization was lower than the ST-segment depression group, but there was no significant difference between the 30-day MACE. Conclusion According to the results of ECG examination, the incidence of ischemia-free electrocardiogram in patients with NSTEMI is high, and the short-term prognosis is better than that in the ST-segment depression group. However, it still needs to be highly concerned, and timely reperfusion therapy may improve the prognosis.
