In the Danish ICD Study in Patients With Dilated Cardiomyopathy (DANISH), which assessed the benefit of prophylactic ICDs in patients with nonischemic cardiomyopathy and an LVEF below 35%, the primary outcome of death from any cause was not statistically different from those on standard heart failure therapy. [136] SCD occurred less often in the ICD group (4.3%) than in the control group (8.2%). When stratified by age, patients younger than 59 years old derived a mortality benefit with ICD as compared to those older than 59 years who had no difference in primary outcome. Background beta blocker therapy was administered to more than 90% of patients in both groups. [136]
