The study addresses the problem and tests two interventions that have promise of benefit. To date, many of the therapies that have been tested for congestive heart failure have either been ineffective or actually decreased survival. Conventional therapy is still relatively ineffective in that recent studies such as the Congestive Heart Failure - Survival Trial of Antiarrhythmic Therapy (CHF-STAT) have demonstrated a mortality of 40 percent during two-and-half years of follow-up. The implantable cardioverter-defibrillator appears to be effective in patients who are resuscitated from cardiac arrest, but until recently, the devices required a thoracotomy and had to be reserved for patients with the highest risk for sudden death. The newer transvenous devices with pectoral patches can now be considered for broader applications. Although there have been mixed results with amiodarone in patients with congestive heart failure, there is a general consensus that it could be effective in the proper subset of patients with congestive heart failure. A comparison of the optimal device and drug is appropriate for such a high risk population.\n\nDESIGN NARRATIVE:\n\nThree-armed, randomized, multicenter trial conducted at over 125 North American, Australian and New Zealand sites. Patients were enrolled over 2.5 years after being randomly assigned to amiodarone, matched placebo or an implantable cardiac defibrillator (ICD). Median follow-up was 45.5 months. All three arms used conventional therapy for heart failure and coronary artery disease (ACE inhibitors, lipid lowering and beta-blockers). The central hypothesis was that amiodarone or the ICD would improve survival compared to placebo. The primary outcome was the prevention of all-cause mortality. Secondary outcome measures included cardiac mortality and arrhythmic mortality, morbidity, quality of life, and incremental cost-effectiveness of the interventions.\n\nThe study completion date listed in this record was obtained from the \"End Date\" entered in the Protocol Registration and Results System (PRS) record."}, "EligibilityModule"=>{"Gender"=>"All", "MaximumAge"=>"90 years", "MinimumAge"=>"19 years", "StdAgeList"=>{"StdAge"=>["Adult", "Older Adult"]}, "HealthyVolunteers"=>"No", "EligibilityCriteria"=>"Patients with New York Heart Association class II or class III heart failure and ejection fraction less than or equal to 35%."}, "IdentificationModule"=>{"NCTId"=>"NCT00000609", "BriefTitle"=>"Sudden Cardiac Death in Heart Failure Trial (SCD-HeFT)", "Organization"=>{"OrgClass"=>"NIH", "OrgFullName"=>"National Heart, Lung, and Blood Institute (NHLBI)"}, "OrgStudyIdInfo"=>{"OrgStudyId"=>"112"}, "SecondaryIdInfoList"=>{"SecondaryIdInfo"=>[{"SecondaryId"=>"U01HL055766", "SecondaryIdLink"=>"https://reporter.nih.gov/quickSearch/U01HL055766", "SecondaryIdType"=>"U.S. NIH Grant/Contract"}]}}, "ArmsInterventionsModule"=>{"InterventionList"=>{"Intervention"=>[{"InterventionName"=>"amiodarone", "InterventionType"=>"Drug"}, {"InterventionName"=>"defibrillators, implantable", "InterventionType"=>"Device"}]}}, "ContactsLocationsModule"=>{"OverallOfficialList"=>{"OverallOfficial"=>[{"OverallOfficialName"=>"Kerry Lee", "OverallOfficialAffiliation"=>"Duke University"}]}}, "SponsorCollaboratorsModule"=>{"LeadSponsor"=>{"LeadSponsorName"=>"National Heart, Lung, and Blood Institute (NHLBI)", "LeadSponsorClass"=>"NIH"}}}}}}
