Implication

Supports ventilatory capacity not limiting exercise in stable HF; leaves open prospective studies on alternative mechanisms.

Structured PICO

Does ventilatory capacity limit exercise capacity in patients with chronic stable heart failure?

Population

74 patients with chronic stable heart failure (mean age 50.6 years, LVEF 30%) and 36 controls (mean age 48.9 years).

Comparator

36 healthy controls

Outcome

Ventilatory capacity in relation to exercise capacity (Peak VO2, VE/VCO2 slope, ventilation at peak exercise, MVV)surrogate

Ventilatory capacity does not appear to be the primary limiting factor for exercise capacity in patients with chronic stable heart failure.
