Of note is the trend toward a reduction in the combined end point of hospitalizations and cardiac deaths ( relative risk , 0.82 [ CI , 0.65 to 1.03 ] , P = .08 ) , which was significant in patients with nonischemic etiology ( relative risk , 0.56 [ CI , 0.36 to 0.87 ] , P = .01 ) and absent in the ischemic group ( relative risk , 0.95 ) .
