MEDINA PALOMINO, Félix et al. ST segment elevation in aVR derivation in acute coronary syndrome with persistent elevation of ST segment: Literature review following a case. Rev Med Hered [online]. 2016, vol.27, n.2, pp.106-110. ISSN 1018-130X.

During last years an association between elevation of the ST segment in the aVR derivation with the affection of the anterior descending coronary artery (ADCA), left coronary artery trunk (LCT) and right coronary artery (RCA) in the context of acute myocardial infarction with elevated ST segment (AMI-ESS) has been observed. The electrocardiogram may predict with 80% accuracy the affection of the LCT versus ADCA when the relation of aVR over V1 in higher than1. Moreover, an elevation of the ST segment in aVR is associated with higher 30-day mortality in patients with AMI-ESS of the anterior and inferior side. Therefore, we emphasize the importance of analyzing the elevation of the ST segment in aVR in patients with AMI-ESS of the anterior side as it predicts extensive vascular affection and worsens prognosis.

Keywords : Acute anterior wall myocardial infarction; electrocardiography; prognosis.
