Cardiac Autonomic Dysfunction in Childhood Cancer Survivors

Sponsor: St. Jude Children's Research Hospital

Summary

This study is being done to evaluate heart rate activity and sleep patterns, among participants in the Long-Term Follow-Up (LTFU) study. Primary Objective Using mobile health (mHealth) technologies in a large and well-characterized cohort of childhood cancer survivors, our primary objective is to understand the magnitude of increased risk of cardiac autonomic dysfunction by (a) comparing prevalence rates among survivors and siblings, and (b) determining the prevalence within specific subgroups of childhood cancer survivors defined by race, sex, cancer type and treatment exposures, and type and severity of chronic health conditions. Secondary Objectives Among long-term (≥5 years) survivors of childhood cancer (a) identify demographic, disease, treatment and cognitive-behavioral factors associated with an increased risk of cardiac autonomic dysfunction, (b) develop and validate risk prediction models for future clinical use in identifying individuals who may benefit from targeted interventions, and (c) investigate associations between dysfunction and perceived well-being.
