Peak VO2 and systolic pressure predict outcome in HF

In a series of 500 patients with chronic heart failure (HF), the three-year survival rate was excellent in patients with a peak V_O2 above 14 mL/min/kg (top curve). Among patients with a lower peak V_O2, three-year survival was higher in those able to achieve a peak systolic blood pressure above 120 mmHg with exercise (p = 0.02).
