ECG Quantification of Myocardial Scar and Risk Stratification in MADIT-II

摘要

BackgroundLow left ventricular ejection fraction (LVEF) increases risk for both sudden cardiac death (SCD) and for heart failure (HF) death; however, implantable cardioverter-defibrillators (ICDs) reduce the incidence of SCD, not HF death. Distinguishing individuals at risk for HF death (non-SCD) vs. SCD could improve ICD patient selection.
