MADIT-II Risk Model (ICD Benefit Prediction) Calculator

MADIT-II Risk Model: Explanation and Clinical Context The MADIT-II Risk Model is a validated tool to estimate the potential survival benefit of an implantable cardioverter-defibrillator (ICD) in patients with prior myocardial infarction and reduced left ventricular ejection fraction (LVEF <30%). It incorporates clinical variables including age, NYHA class, QRS duration, serum creatinine, history of myocardial infarction, diabetes status, and resting heart rate. Each factor contributes to a cumulative risk score, stratifying patients into low, intermediate, or high benefit categories for ICD implantation.

This model assists clinicians in individualized risk assessment, guiding ICD therapy decisions and optimizing patient outcomes.
