Evaluation of the Improvement of Primary Prevention in Ischemic Cardiomyopathy Patients Using New Screening and Referring System (Advance-ICM)

Yonsei University300 enrolled

Overview

The patients who undergo ICD(implantable cardioverter defibrillator) implantation for the primary prevention of sudden cardiac death with severe LV(left ventricle) dysfunction (ejection fraction ≤ 40%) by ICM(idiopathic cardiomyopathy). Indications for ICD implantation for primary prevention in accordance with 2016 revised Korean indication guideline on ICD implantation * FU LVEF(Left Ventricular Ejection Fraction) ≤ 30% (at least 40 days post-myocardial infarction) * FU LVEF 31\~35%, NYHA(the New York Heart Association) class II, III (at least 40 days post-myocardial infarction) * FU LVEF ≤ 40%, NSVT(non-sustained ventricular tachycardia) (Holter), inducible VF(ventricular flutter) or sustained VT(ventricular tachycardia) at electrophysiological study (at least 40 days post-myocardial infarction)
