Hello. Because your question about what role does lead aVR play in acute myocardial infarction is quite deep in the field of cardiology - Interventional Cardiology, so please answer in the shortest way. In acute myocardial infarction, lead aVR elevation may be present in acute left main coronary artery occlusion or proximal LAD, even in tri-vessel stenosis. Therefore, if acute myocardial infarction with AVR lead elevation greater than 1 mm or > V1 may be an indicator of severe cardiovascular status, the risk of death is high.
Thank you for trusting and sending questions about Vinmec Health System. Best regards!
