Overview

Single CPET may underestimate capacity in chronic HF; leaves open whether repeats improve reproducibility for clinical use.

Structured PICO

Are cardiopulmonary exercise test parameters reproducible across consecutive tests in patients with chronic heart failure?

P
Population
30 patients with chronic cardiac failure
I
Intervention
Second and third consecutive cardiopulmonary exercise tests
C
Comparator
First cardiopulmonary exercise test
O
Outcome
Reproducibility of cardiopulmonary parameters including treadmill exercise time, peak VO2, VCO2, and VEsurrogate

A single cardiopulmonary exercise test underestimates exercise capacity in heart failure patients, indicating that at least two tests should be performed for accurate assessment.
