Caterini JE, et al. – The aim of this study was to explore the correlation between vascular stiffness, percentage body fat, body mass index (BMI), and cardiac function in adolescents across the weight spectrum through both cardiac magnetic resonance (CMR) and standard applanation tonometry (AT)–based pulse wave velocity (PWV) measurements. The data showed that increasing arterial stiffness and decreasing cardiac function were evident among the overweight and obese cohort. PWV estimated by CMR could detect early increases in arterial stiffness vs. traditional AT measurements of PWV.
