Clinical Trial Summary

This is a behavioral study that will examine changes in physical activity and vascular health in response to a digital tool (app) that will appear on participant's lock screen of their Android phone. Participants will be asked to use this app for 3 months and to wear a Fitbit device continuously throughout the study. Participants will be asked to complete questionnaires, participate in fitness testing and measures of cardiovascular health at 3 months and 6 months after baseline assessments. The hypothesis is that exposure to the app will lead to increased physical activity volume and improved microvessel function.

Related Conditions & MeSH terms

• Breast Cancer
• Leukemia
• Lymphoma

Intervention

Behavioral:
• HeartPhone app
Evaluative conditioning (temporally distributed micro-doses presented upon activation of smartphone screen)

Drug:
• Acetylcholine
Endothelium-dependent vasodilation is tested with the localized delivery of the neurotransmitter
• Sodium Nitroprusside
Endothelium-independent vasodilation is tested with the localized delivery of the nitric oxide donor
• L-Arginine, N2-((4-Methylphenyl)Sulfonyl)-, Methyl Ester
This nitric oxide inhibitor is continuously given during the localized delivery of the endothelium-dependent agonist acetycholine.
