Key result
Three-stage risk stratification successfully classifies ~92% of post-MI patients into high- or low-risk MAE groups.
Why the study?
Improved approaches are needed to identify patients at highest risk for major arrhythmic events after myocardial infarction who are candidates for implantable cardioverter-defibrillators.
What is the predictive value of five common risk stratification tests, alone or in combination, for major arrhythmic events after myocardial infarction?
Meta-Analysis
What is the predictive value of five common risk stratification tests, alone or in combination, for major arrhythmic events after myocardial infarction?
Individual noninvasive tests have limited predictive value for major arrhythmic events post-MI, but a staged combination approach can effectively stratify patients into high and low risk groups.

Staged noninvasive testing with EPS may refine post-MI arrhythmic risk stratification; leaves open impact on ICD selection and outcomes.
Bailey et al. (2001) conducted a meta-analysis in myocardial infarction. Risk stratification tests (signal-averaged ECG, HRV, ambulatory ECG, LVEF, EPS) was evaluated on Major arrhythmic events (MAEs). A three-stage combination of risk stratification tests successfully classified 91.8% of post-myocardial infarction patients into high-risk (41.4% two-year MAE risk) or low-risk (2.9% risk) groups.
