Comparison of Selvester QRS score with magnetic resonance imaging measured infarct size in patients with ST elevation myocardial infarction
Journal of Electrocardiology, 06/21/2012
Carlsen EA et al. – Selvester QRS score correlated only moderately with delayed enhancement–magnetic resonance imaging (DE–MRI) myocardial infarct (MI) size. Selvester QRS score overestimated MI size.
Methods- The relationship was evaluated retrospectively in 55 first–time STEMI patients 3 months after receiving primary percutaneous coronary intervention.
- Selvester QRS score and DE–MRI MI size were significantly correlated, r = 0.41 (P < .01).
- The difference between the Selvester QRS score and DE–MRI was 5.8% MI of the left ventricle (95% confidence interval, 2.9%–8.6%).
- Furthermore, increasing difference between Selvester QRS score and DE–MRI was observed with increasing MI size.
