Format Double-blinded multi-center RCT
Treatment ICD or Amiodarone
Control Placebo
Population CCF (NYHA II/III; LVEF <35)
Inclusion criteria Patients had to be at least 18 years of age and have New York Heart Association (NYHA) class II or III chronic, stable CHF due to ischemic or nonischemic causes and a left ventricular ejection fraction (LVEF) of no more than 35 percent.

Nonischemic CHF was defined as left ventricular systolic dysfunction without marked stenosis.
