Compared to patients with normal LV function , those with severely impaired LVEF had higher 1-year rates of net adverse clinical events ( 27.1 vs. 14.2 % , p < 0.0001 ) , major adverse cardiovascular events ( 20.7 vs. 9.5 % , p < 0.0001 ) , cardiac death ( 10.6 vs. 1.2 % , p < 0.0001 ) , and non-coronary artery bypass graft major bleeding ( 12.5 vs. 6.6 % , p = 0.001 ) , differences which persisted after adjustment for baseline characteristics .
