Resumen
DE LA TORRE FONSECA, Luis Mariano et al. Relationship of ST-segment elevation in AVR to cardiovascular complications. Rev Cubana Invest Bioméd [online]. 2023, vol.42 Epub 10-Mayo-2023. ISSN 1561-3011.
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.
