Dr. Tomio Tran and Prof. James Rudd discuss using smartwatches to measure VO2 max in ACHD patients, comparing it to CPET testing. They explore challenges in interpreting data, correlation between methods, and potential benefits for monitoring and prognosis. Highlighting the integration of smartwatches in routine care and the need for further research.
Smartwatches can overestimate peak heart rate and VO2 max compared to CPET in ACHD patients.
Monitoring VO2 max in ACHD patients with smartwatches can help track health status and guide treatment decisions effectively.

Comparison of Smartwatch VO2 Measurement with CPET Testing
The podcast episode discusses a study conducted by Dr. Tomio Tran, comparing the use of a smartwatch to measure VO2 max in patients with adult congenital heart disease with CPET testing. The study aimed to assess the accuracy of smartwatch measurements in detecting changes in VO2 max over time compared to CPET. It highlighted the increasing use of smartwatches in healthcare and the potential for non-invasive monitoring as an alternative to CPET testing.
Importance of VO2 Max in Adult Congenital Heart Disease Patients
The importance of VO2 max in adult congenital heart disease patients is emphasized in the podcast. A higher VO2 max is linked to lower morbidity and mortality in various populations. The study focused on the ACHD population, highlighting the significance of monitoring VO2 max in these patients to track their health status over time and guide treatment decisions effectively.
Factors Influencing Smartwatch and CPET VO2 Measurements
The podcast delves into the factors influencing the correlation between smartwatch and CPET-derived VO2 max, such as heart rate, age, sex, height, and weight. The study found that smartwatches tended to overestimate peak heart rate and VO2 max compared to CPET. It also discussed the potential benefits and challenges of integrating smartwatches into routine care, highlighting the need for further research to assess their impact on patient outcomes.
In this episode of the Heart podcast, Digital Media Editor, Professor James Rudd, is joined by Dr Tomio Tran from Seattle. They discuss his paper about how well smartwatches measure peak oxygen consumption compared to CPET in ACHD subjects.
