Abstract

Introduction ST-segment elevation in lead aVR 12-lead ECG provides prognostic information suitable enpacientes with acute coronary syndrome without ST segment elevation.

To evaluate the contribution of laelevación ST segment in aVR in patients with NSTEACS in the prognosis of death within a year of the first episode.

Method A retrospective study in patients ingresadosen Hermanos Ameijeiras Hospital condiagnóstico of acute coronary syndrome without ST-segment elevation in the period May 2011 to August 2013.

Results prevailed the age group 65 and over (41.8% and 40.0%), males (67.3% and 64.5%) and the presence of two or more comorbidities in both groups (78.2% and 67.3%). Unstable angina was the most frequent diagnosis (63.6% and 66.3%) and the Killip-Kimball class I (61.8% and 80.9% respectively) in both groups. Later stages of that class were associated with the group presenting ST-segment elevation in aVR (12.7% vs 4.5% [p = 0.03]; 5.5% vs 0.9% [p = 0.03]) also predominated in this group multivessel coronary disease (76.8% [p = 0.02]. Death per year in the group with ST elevation in aVR delsegmento (25.5% p = 0.003 OR 2.54 95% CI 1.33-4.85).

Conclusion: ST elevation in ECG aVR is an important predictor of death within 1 year. Useful for improving initial risk stratification and management of these patients.
