Objects: We assessed the ability of ST-segment elevation in lead aVR to predict left main and/or 3-vessel disease (LM/3VD) in patients with acute coronary syndromes (ACS).
Meterial and Method: 410 patients with ACS, who underwent coronary angiography, were evaluated.
Results: 131 (31.9%) patients have been LM/3VD. ST segment elevation > 0.05 mV in leads aVR have been an independent predictor LM/3VD with sensitivity, specificity, positive predictive value PPV) and negative predictive value (NPV) 74.0%, 78.1%, 61.4% and 86.5%, respectively (p<0.001). ST segment elevation > 0.05 mV in leads aVR with ST segment depression in leads V4-V6 have related LM/3VD with sensitivity, specificity, PPV and NPV 44.3%, 92.8%, 74.4% and 75.2%, respectively (p<0.001). ST segment elevation > 0.1 mV in leads aVR have related LM/3VD with sensitivity, specificity, PPV and NPV 51.9%, 87.1%, 65.1% and 79.4%, respectively (p<0.001).
Conclusions: ST segment elevation > 0.05 mV in leads aVR have been an independent predictor LM/3VD in patients with ACS.
