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