Does the modified EHRA (mEHRA) score improve symptom classification and health utility assessment compared to the original EHRA score in patients with atrial fibrillation?
The modified EHRA score provides clearer separation in health utility for atrial fibrillation patients, suggesting Class 2b symptoms as an appropriate threshold for interventions like ablation.
Based on patients' own assessment of their health status and the disease-specific AFEQT, the EHRA score can be considered a useful semi-quantitative classification. The mEHRA score has a clearer separation in health utility to assess the cost efficacy of interventions such as ablation, where Class 2b symptoms appear to be the appropriate treatment threshold.
