Defibrillator, Heart Failure and Sudden Cardiac Death

A discourse on primary prevention implantable cardioverter-defibrillators for heart failure is understandable, but answers must be sought appropriately

MARCH 28, 2025

The implantable cardioverter-defibrillator (ICD) remains one of the most effective therapies for preventing sudden cardiac death (SCD). Data supporting the role of primary prevention ICDs in patients with heart failure were generated by rigorous randomized controlled trials (RCTs).1

This study by Fujita Health University researchers revealed that kidney function, considered in terms of estimated glomerular filtration rate (eGFR), can be used as a predictor for SCD in patients with congestive heart failure. During the follow-up period, 198 of these patients suffered from SCD.

This randomized clinical trial assesses whether cardioverter-defibrillator implantation is more effective than amiodarone therapy for the primary prevention of all-cause mortality and secondary prevention of sudden cardiac death, hospitalization for heart failure, and use of a pacemaker among patients with chronic Chagas cardiomyopathy.

Sudden cardiac death (SCD) remains a pressing health issue, affecting hundreds of thousands each year globally. The heterogeneity among SCD victims, ranging from individuals with severe heart failure to seemingly healthy individuals, poses a significant challenge for effective risk assessment.

Unlike a heart attack, cardiac arrest is an electrical malfunction that causes the heart to stop beating suddenly. This results in a failure to pump blood to the brain and other vital organs. Without immediate intervention, sudden cardiac death can occur within minutes.

Introduction Wearable cardioverter-defibrillators (WCD) have emerged as a valuable tool in the management of patients at risk for life-threatening arrhythmias. These devices offer a non-invasive and temporary solution, providing continuous monitoring and the potential for prompt defibrillation when needed.

For the past four decades, implantable cardioverter defibrillator (ICD) therapy has become the standard of care for preventing sudden cardiac death in high-risk individuals. The rate of ICD implantation has risen due to the increasing population age and the growing prevalence of cardiac arrhythmias.
