HR = Hazard ratio; CI = confidence Interval; LVEF = left ventricular ejection fraction; BNP = Brain Natriuretic Peptide.

^*Adjusted for etiology, LVEF, ProBNP, baseline SBP and SBP reactivity to stress task.

^†Adjusted for the variables in the a priori planned model, as well as depression score and diuretic use.
