[The patient with chronic heart failure].

Area of Science:

• Cardiology
• Medical Technology
• Clinical Electrophysiology

Context:

• Implantable cardioverter-defibrillator (ICD) therapy is a standard treatment for preventing sudden cardiac death.
• While ICD indications haven't expanded recently, rising implantation numbers are expected due to an aging population and wider access in underserved regions.
• Despite over two decades of use in Germany, fundamental questions regarding ICD therapy persist.

Purpose:

• To address critical unanswered questions in implantable cardioverter-defibrillator (ICD) therapy.
• To explore the optimal timing for ICD implantation.
• To evaluate the utility of predictors in excluding patients from ICD therapy and to reassess current risk stratification methods.

Summary:

• Current research highlights the need for prospective clarification on key aspects of ICD implantation.
• Key questions include determining the ideal timing for ICD implantation and identifying reliable predictors for patient selection.
• There is a need to rethink risk stratification from a static snapshot to a dynamic, time-dependent assessment.
• Adjuvant therapies like ventricular tachycardia (VT) ablation or antiarrhythmic drugs are suggested, but optimal timing remains unclear.

Impact:

• This research aims to refine patient selection and treatment timing for ICD therapy, potentially improving outcomes.
• Findings could lead to more personalized and effective strategies for sudden cardiac death prevention.
• The study may influence clinical guidelines regarding risk stratification and the use of adjuvant therapies in conjunction with ICDs.
