Cardiopulmonary Exercise Test Reference Values for Repaired Tetralogy of Fallot Patients

A study by Benedetta Leonardi provides sex- and age-specific reference values for cardiopulmonary exercise testing in patients with repaired Tetralogy of Fallot. The dataset includes results from 290 asymptomatic patients tested on treadmill and cycle ergometer protocols between 2020 and 2024. Key metrics include VO₂ peak, oxygen pulse, VE/VCO₂ slope, and oxygen uptake efficiency slope (OUES).

Use Cases

• Establishing clinical reference ranges for CPET metrics based on modality and patient sex.
• Comparing exercise capacity between treadmill and cycle ergometer testing protocols.
• Analyzing the relationship between physical activity levels (assessed via IPAQ) and cardiopulmonary performance.
• Investigating age-stratified differences in VO₂ peak and percent-predicted VO₂.

Strengths

• Includes data from 290 patients, providing a substantial cohort for this specific clinical population.
• Provides specific median values for key CPET parameters like VO₂ peak (26.4 mL/min/kg) and oxygen pulse (9.9 mL/beat).
• Stratifies results by sex, age group (<18 vs. ≥18 years), and exercise modality (treadmill vs. cycle).
• All participants had undergone cardiac magnetic resonance imaging (CMR), linking exercise data to cardiac structure.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the underlying data table is unknown, which may limit suitability assessment.
• The data reflects a specific clinical cohort; generalizability to other populations may be limited.
