Abstract

Introduction: The pattern of "ST-segment elevation in aVR" in acute coronary syndrome is associated with increased mortality.

Objective: To evaluate the relationship between the pattern of "ST-segment elevation in aVR" and nonlethal cardiovascular complications.

Methods: Observational cross-sectional study, with analytical component of all patients admitted with non-ST-segment elevation acute coronary syndrome at the "Manuel Fajardo" University Hospital of Havana between 2016 and 2020.

Results: Female gender predominated in the first group, with an average age of 78 years. There was incidence of ischemic heart disease (75 % and 56.4 %) and arterial hypertension (78.8 % and 85.8 %). A significant statistical relationship was determined between the pattern with ST-segment elevation in aVR and cardiovascular complications with a relative risk of 5.769 times.

Conclusions: ST-segment suprathreshold pattern in non-ST-segment elevation acute coronary syndrome predicts non-lethal in-hospital cardiovascular complications.
