Clinical Assessment and Targeted Imaging to Characterize High-Risk Atherosclerotic Cardiovascular Disease of Survivors in SJLIFE

Starting soon

Conditions studied: Atherosclerotic Cardiovascular Disease

In brief

Childhood cancer survivors are at increased risk for premature atherosclerotic cardiovascular disease (ASCVD) due to cancer treatment-related exposures, including radiation therapy and platinum-based chemotherapy. Current ASCVD risk assessment tools may underestimate cardiovascular risk in younger survivors. This observational study performs detailed cardiovascular phenotyping using imaging, blood-based biomarkers, and vascular function testing among adult survivors enrolled in the St. Jude Lifetime Cohort (SJLIFE), with comparison to community controls, to better characterize subclinical ASCVD risk and inform survivor-specific prevention strategies. Primary Objective: Perform deeper phenotyping of SJLIFE participants at treatment-related risk of atherosclerotic cardiovascular disease \[ASCVD\] to facilitate early detection of pathophysiological targets appropriate for remediation. Secondary Objectives: Determine the distribution of lipoprotein (a) levels and prevalence of elevated levels among survivors with any treatment related exposure-based risk for ASCVD overall and then compared to community controls. Evaluate prevalence of clinical and imaging markers of ASCVD risk among survivors exposed only to platinum chemotherapy and compare that to community controls.
