Lead aVR ST- segment elevation and cTnI positive are closely correlated to the prognosis of NSTE-ACS patients. However, there are few studies applying the two predictors to early risk stratification in NSTE-ACS patients. Method Two hundred and five cases of NSTE-ACS patients followed up for 6 months after discharge were reviewed. All patients were divided into four groups： Group A-cTnI negative combined with aVR-non-ST-segment elevation group （100 cases） ; Group B-cTnI negative combined with aVR-ST-segment elevation group （31 cases） ; Group C-cTnI positive combined with aVR-non-ST-segment elevation group （43 cases） ; Group D-cTnI positive combined with aVR-ST-segment elevation group （31 cases）. There was no significant difference in gender, age, old myocardial infarction, previous PCI history, hypertension, and diabetes between aVR-ST elevation group and no aVR-ST elevation group. The morbidity of left main or three-vessel coronary artery disease as well as adverse cardiovascular events in the four groups were observed and analyzed. Results （i） The morbidity of left main or three-vessel coronary artery disease was highest in Group D （87.1%） , and was markedly higher in Group B （41.9%） than that in Group A （7%） or Group C （9.3%） ; （ii） The incidence of adverse cardiovascular events was highest in Group D （77.4%）, and was much higher in B （35.5%） as compared with that tin Group A （1%） or group C （7%）. Conclusion Electrocardiographic lead aVR ST-segment elevation combined with cTnI positive has an important clinical value in predicting the prognosis of the patients with NSTE-ACS.展开更多
