Feasibility and Agreement of Remote Evaluation of Resting Heart Rate and Heart Rate Variability in Survivors of Hodgkin Lymphoma Treated With Chest Radiation (PILOT STUDY-SURVIVOR)

Primary Objective The objective is to determine the feasibility and agreement of remote evaluation of resting heart rate and HRV using the commercially available WHOOP® wrist monitor, compared to in-office measurements using AtCor Medical SphygmoCor HRV Software, in a cohort of 40 St. Jude Life Study participants with a history of mantle radiation for management of Hodgkin lymphoma. Elucidating the mechanisms that contribute to adverse cardiovascular outcomes and reduced quality of life among the growing population of childhood cancer survivors is paramount. Cancer, certain cancer drugs, radiation therapy, cancer-associated lifestyle disturbances, and cancer-independent comorbidities combine to predispose cancer survivors to autonomic dysfunction (AD). Reduced heart rate variability (HRV) has been described in various cancer cohorts. Furthermore, these markers of AD have been implicated in adverse outcomes in oncology patients, including increased mortality, exercise limitation, and fatigue. However, data are largely derived from small studies with methodological limitations, and the contribution of AD to overall morbidity and mortality in cancer survivors is not well understood.
