Prognostic value of lead aVR in patients with a first non-ST-segment elevation acute myocardial infarction

ST-segment elevation in lead aVR has been associated with severe coronary artery lesions in patients with acute coronary syndromes, but the prognostic significance of this finding is unknown. We analyzed the initial ECG in 775 consecutive patients admitted to our center with a first acute myocardial...

Zusammenfassung:	ST-segment elevation in lead aVR has been associated with severe coronary artery lesions in patients with acute coronary syndromes, but the prognostic significance of this finding is unknown. We analyzed the initial ECG in 775 consecutive patients admitted to our center with a first acute myocardial infarction without ST-segment elevation in leads other than aVR or V1. The rates of in-hospital death in patients without (n=525) and with 0.05 to 0.1 mV (n=116) or > or =0.1 mV (n=134) of ST-segment elevation in lead aVR were 1.3%, 8.6%, and 19.4%, respectively (P
