Key result
The combination of HRT2 and increased mTWA was associated with a significantly increased risk of sudden cardiac death in post-myocardial infarction patients (OR 63.3; 95% CI 6.8-585.8; p<0.001).
Why the study?
Do non-invasive electrophysiological predictors (HRT, mTWA, DC) improve risk assessment for sudden cardiac death and cardiovascular mortality in post-myocardial infarction patients?
Population
111 post-myocardial infarction patients, aged 64.1 ± 10.5 years, with MI occurring 2 months to 36 years…

May enhance SCD risk stratification in post-MI patients with LVEF >40%; leaves open prospective validation before guiding therapy.

The combination of heart rate turbulence and microvolt T-wave alternans provides strong predictive value for sudden cardiac death and cardiovascular mortality in post-MI patients, particularly those with LVEF >40%.
Sulimov et al. (2015) conducted a cohort in Post-myocardial infarction (n=111). Combination of HRT2 and increased mTWA vs. Any other combination including those with reduced LVEF was evaluated on Sudden cardiac death (OR 63.3, 95% CI 6.8-585.8, p=<0.001). The combination of HRT2 and increased mTWA was associated with a significantly increased risk of sudden cardiac death in post-myocardial infarction patients (OR 63.3; 95% CI 6.8-585.8; p<0.001).
