Epicardial Adipose Tissue: A Piece of The Puzzle in Pediatric Hypertension.

BACKGROUND AND PURPOSE

Epicardial adipose tissue (EAT) is a metabolically active tissue located on the surface of the myocardium, which might have a potential impact on cardiac function and morphology. The aim of this study was to evaluate whether EAT is associated with essential arterial hypertension (AH) in children and adolescents.

METHODS

Prospective cardiovascular magnetic resonance (CMR) study and clinical evaluation were performed on 72 children, 36 of whom were diagnosed with essential AH, and the other 36 were healthy controls. The two groups were compared in volume and thickness of EAT, end-diastolic volume, end-systolic volume, stroke volume, left ventricular (LV) ejection fraction, average heart mass, average LV myocardial thickness, peak filling rate, peak filling time and clinical parameters.

RESULTS

Hypertensive patients have a higher volume (16.5 ± 1.9 cm and 10.9 ± 1.5 cm ( = -13.815, < 0.001)) and thickness (0.8 ± 0.3 cm and 0.4 ± 0.1 cm, (U = 65.5, < 0.001)) of EAT compared to their healthy peers. The volume of EAT might be a potential predictor of AH in children.

CONCLUSIONS

Our study indicates that the volume of EAT is closely associated with hypertension in children and adolescents.
