Current implantable cardioverter-defibrillator (ICD) guidelines for preventing sudden cardiac death are suboptimal. Multifactorial risk stratification shows promise for better patient selection, moving beyond ejection fraction alone.
Area of Science:
- Cardiology
- Electrophysiology
- Preventive Medicine
Background:
- Sudden cardiac death (SCD) prevention via implantable cardioverter-defibrillators (ICDs) is a key goal in arrhythmology.
- Current risk stratification methods for ICDs are imprecise, leading to both under- and over-utilization.
Purpose of the Study:
- To review limitations in current guidelines for SCD prevention in cardiomyopathy patients.
- To explore multifactorial approaches for improved risk stratification in ICD candidates.
Main Methods:
- Review of contemporary guidelines and available data on SCD prevention.
- Discussion of invasive electrophysiological testing, including programmed ventricular stimulation.
- Highlighting ongoing multicenter studies for enhanced risk stratification.
Main Results:
- Novel strategies show promise for selecting appropriate candidates for ICD implantation.
- Improved identification of patients who will benefit from ICDs and those who will not.
Conclusions:
- Ejection fraction alone is becoming insufficient for arrhythmic risk stratification in heart failure.
- Multifactorial approaches and advanced testing are crucial for future SCD prevention strategies.
