Serial peak VO2 monitoring may refine prognostication in chronic HF; leaves open whether it should guide management decisions.
Do changes over time in exercise capacity and echocardiographic measurements predict mortality in patients with chronic heart failure?
Monitoring changes in peak VO2 over time provides significant prognostic information regarding survival in patients with chronic heart failure, outperforming changes in LVEF.
