Abstract：Objective To evaluate the predictive value of ST-segment elevation in aVR lead for non-ST-segment elevation acute myocardial infarction.MethodsTwenty-seven patients with ECG changes of ST-segment depression≥0.1 mV complicating ST-segment elevation in aVR lead were regarded as observation group while another 50 cases with ECG changes of ST-segment depression≥0.1 mV but without ST-segment elevation in aVR lead complicated were taken as control group. The incidence rates of nonST-segment elevation acute myocardial infarction were followed up.ResultsIn observation group, there were 7 cases(25.9%) diagnosed with non-ST-segment elevation myocardial infarction while there was one(2%) in the control group. The difference of its incidence rate was statistically significant(P<0.05) between the two groups.ConclusionThe ST-segment elevation in aVR lead proves to be clinically valuable in predicting non-ST-segment elevation acute myocardial infarction and thus it deserves to be paid more attention to.
