Why the study?

Does the STEEP protocol provide comparable exercise testing results to the modified Bruce protocol in patients with chronic cardiac failure?

Population

Patients with chronic cardiac failure

Comparison

STEEP for treadmill and bicycle vs Modified Bruce treadmill protocol

Design

Cross-sectional

Discussion

Implication

May support STEEP treadmill as alternative for peak VO2 assessment in heart failure; leaves open standardization across modalities pending randomized data.

Key Points

This study aims to evaluate the efficacy of a standardized exercise protocol (STEEP) for patients with chronic cardiac failure.
Compared STEEP protocol with modified Bruce protocol in chronic cardiac failure patients.
Assessed exercise time and peak VO2 during treadmill and bicycle exercises.
Utilized heart rate and respiratory exchange ratio measurements at equal exercise stages.
Exercise time was longer with modified Bruce protocol (9.00 +/- 3.02 min, P < 0.05) compared to both STEEP protocols.
Peak VO2 was higher with the STEEP treadmill test than the bicycle protocol (16.66 +/- 4.09 vs 15.01 +/- 3.72 ml.min-1.kg-1, P < 0.05).
Heart rate and respiratory exchange ratio were greater during bicycle exercise at equal stages.

Structured PICO

Does the STEEP protocol provide comparable exercise testing results to the modified Bruce protocol in patients with chronic cardiac failure?

Population

Patients with chronic cardiac failure

Intervention

STEEP (standardized exercise protocol) for treadmill and bicycle

Comparator

Modified Bruce treadmill protocol

Outcome

Exercise time and peak VO2surrogate

The STEEP protocol is a valid alternative to the modified Bruce protocol for exercise testing in chronic heart failure patients, allowing for comparable peak VO2 assessment across treadmill and bicycle modalities.
