Prevalence and prognostic impact of ST-segment elevation in lead aVR among patients with cardiac arrest
Main finding · In-hospital mortalityResult — go to the resultOdds ratio 2.23 95% CI 1.02–4.84Authors' conclusion
ST-segment elevation in lead aVR was present in one in five CA survivors and was independently associated with higher in-hospital mortality.
Study context
- Population
- Patients (≥18 years) with cardiac arrest between 2011 and 2022 who achieved return of spontaneous circulation (ROSC)
- Participants
- 443 cardiac arrest (CA) patients
- Comparison
- STE-aVR vs no STE-aVR
- STE-aVRn = 81
- Outcome
- In-hospital mortality

Baseline characteristics
- Median (interquartile range) age
- 61 years (50-72 years)
- Male
- 60.5% (n = 268)
- Out-of-hospital CA (OHCA)
- 65.7% (n = 291)
- Shockable rhythms
- 29.8% (n = 132)
Prevalence of STE-aVR
- STE-aVR observed
- 18.3% (n = 81)
- Those with STE-aVR more likely to present with OHCA and less likely to have a shockable rhythm
- P < 0.05
