Overview
Implantable cardioverter-defibrillator (ICD) can be used for patients with idiopathic dilated cardiomyopathy (DCM) for primary or secondary prevention of ventricular arryhthmias.
Primary Prevention
- Primary prevention strategy for heart failure patients with NYHA class II or III, and LVEF ≤35% at least 40 days after myocardial infarction is ICD implantation.
- In patients with LVEF ≤30% and prior MI and NYHA class I symptoms , ICD implantation was associated with survival benefit.
- Analysis of [MADIT]], MADIT-II, and SCD-HeFT showed survival benefit of ICD implantation for [[primary prevention of ventricular arrhythmia.
- There was not survival benefit of ICD implantation in patients with NYHA class IV heart failure.
