Please assess the completion status of the following clinical trial:

Trial Title: Efficacy and Safety of Implantable Cardioverter-Defibrillator (ICD) Implantation in the Elderly

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~1. 70 years of age or older~2. Eligible for ICD implementation according to the CMS criteria for primary prevention by one of the following conditions:~   1. Documented prior MI and a measured left ventricular ejection fraction (LVEF) \<=30% (includes New York Heart Association \[NYHA\] class I, II, or III)~  2. Coronary artery disease with a documented prior MI, a measured left ventricular ejection fraction \<=35%, and inducible, sustained ventricular tachycardia (VT) or ventricular fibrillation (VF) at electrophysiology (EP) study~  3. Ischemic dilated cardiomyopathy (IDCM), documented prior MI, NYHA class II and III heart failure, and measured LVEF \<=35%~  4. Non-ischemic dilated cardiomyopathy (NIDCM) \> 3 months, NYHA Class II and III heart failure, and measured LVEF \<=35%~3. Stable condition on Optimal Medical Therapy~4. Able and willing to provide informed consent to participate in this study~Exclusion Criteria:~1. Enrolled in or planning to enroll in a conflicting trial~2. Receiving a bi-ventricular ICD device~3. New York Heart Association class IV heart failure~4. Cardiogenic shock or symptomatic hypotension while in stable baseline rhythm,~5. Coronary artery bypass graft (CABG) or percutaneous transluminal coronary angioplasty (PTCA) within the past 3 months~6. An MI within the past 40 days~7. Clinical symptoms or findings that would make them a candidate for coronary revascularization~8. Irreversible brain damage from pre-existing cerebral disease~9. Any disease other than cardiac disease (e.g. cancer, uremia, liver failure), associated with a likelihood of survival less than 1 year~10. Circumstance that would prevent completion of the trial and follow-up activities, including medical condition
