BACKGROUND: This investigation aims to assess the influence of a mobile
application and smart devices on cardiopulmonary exercise testing (CPET)
over a one-year period in individuals who have high risk for
cardiovascular disease.

METHODS: This is a post-hoc subgroup analysis of Lifestyle Intervention
Using Mobile Technology in Patients with High Cardiovascular Risk: A
Pragmatic Randomised Clinical Trial (LIGHT). In the intervention plus
standard care standard standard care arms, 138 and 103 patients were
recruited, respectively. The 1-year VO2 measurements were adjusted to the
baseline VO2 measurements as the study’s endpoint. VO2 measurements were
taken for each subject during the randomisation and final CPET
examinations.

RESULTS: The intervention plus standard care improved VO2 measurements by
1.1 (adjusted treatment effect 1.1, 95% confidence interval (CI): 0.8,
1.4, p < 0.001) compared to standard care following 1-year follow-up.

CONCLUSION: At a 1-year follow-up, the smart device and mobile
application technologies increased VO2 measurements in individuals with
high cardiovascular risk compared to conventional treatment alone.
