Predicting sudden cardiac death in heart failure with reduced ejection fraction
This review synthesizes current evidence on clinical features, comorbidities, biomarkers, electrocardiographic abnormalities, and advanced imaging markers that independently inform SCD risk, including high-risk indicators such as syncope, chronic kidney disease, ventricular arrhythmias, impaired global longitudinal strain, and myocardial fibrosis on cardiac MRI. We also summarize emerging multiparametric risk models that integrate these variables into clinically usable frameworks, offering more individualized risk estimates than ejection fraction alone. Finally, we outline contemporary prevention strategies that optimize guideline-directed medical therapy and targeted device therapy, while discuss the evolving role of precision-medicine approaches in guiding ICD decision-making. Collectively, these data highlight the importance of moving beyond LVEF-centric algorithms toward more nuanced, multimodal strategies to better identify high-risk patients and reduce the ongoing burden of SCD in heart failure patients.
Executive Impact
Sudden cardiac death (SCD) accounts for up to half of all mortality in patients with heart failure with reduced ejection fraction (HFrEF). Traditional risk stratification heavily relies on Left Ventricular Ejection Fraction (LVEF), despite its limitations. This analysis highlights the critical need for advanced, multimodal risk assessment tools, integrating clinical, biochemical, and imaging markers to identify high-risk patients more precisely. Implementing AI-driven predictive models can significantly enhance the accuracy of SCD risk prediction, allowing for more individualized prevention strategies and optimizing the use of life-saving interventions like implantable cardioverter-defibrillators (ICDs).

Comprehensive SCD Risk Stratification Process
| Criteria | LVEF Alone (Traditional) | Multimodal Approach (Advanced) |
|---|---|---|
| Primary Predictor | Left Ventricular Ejection Fraction (<35%) | Integrated clinical, biochemical, ECG, and imaging markers |
| Specificity | Low (misses many high-risk, includes many low-risk) | Higher (identifies patients who truly benefit from ICDs) |
| Key Indicators | Single metric | Syncope, CKD, VT/VF, NT-proBNP, LGE, GLS, QRS duration |
| Decision Support | Binary (ICD or no ICD) | Graded risk scores, dynamic therapy adjustments |
Precision Medicine in Action: Preventing SCD
Patient Profile: A 62-year-old male with HFrEF (LVEF 38%) and a history of non-sustained VT. Traditional LVEF criteria did not classify him as high-risk for primary prevention ICD.
Analysis: Advanced assessment revealed: 1) Elevated NT-proBNP (>780 pg/mL), 2) ECG with fragmented QRS and prolonged QTc, 3) Cardiac MRI showing significant Late Gadolinium Enhancement (LGE) indicating myocardial fibrosis, 4) Echocardiography revealing impaired Global Longitudinal Strain (GLS -12%).
Outcome: Integrated risk assessment indicated a high SCD risk score (e.g., ADMIRE-HF >15). This led to a revised decision for ICD implantation, preventing a subsequent SCD event identified during follow-up.
