Key result
Major ST segment elevation (>1 mm) in the aVR lead was associated with significantly higher mortality (17.7% vs 0.9%, p=0.001) compared to minor elevation in patients with acute coronary syndrome.
Why the study?
Does major ST segment elevation (>1 mm) in lead aVR predict worse angiographic outcomes and higher mortality compared to minor elevation (0.5-1 mm) in patients presenting with chest pain?
Observational (n=887)
No
Does major ST segment elevation (>1 mm) in lead aVR predict worse angiographic outcomes and higher mortality compared to minor elevation (0.5-1 mm) in patients presenting with chest pain?
Major ST segment elevation (>1 mm) in lead aVR is a significant predictor of severe coronary artery disease (such as three-vessel disease) and increased mortality in patients presenting with chest pain.

Abuzer Coşkun (2011) conducted an observational in Acute coronary syndrome (n=887). Major ST segment elevation in aVR lead (>1 mm) vs. Minor ST segment elevation in aVR lead (0.5-1 mm) was evaluated on Mortality (p=0.001). Major ST segment elevation (>1 mm) in the aVR lead was associated with significantly higher mortality (17.7% vs 0.9%, p=0.001) compared to minor elevation in patients with acute coronary syndrome.
