AIM: The purpose of this study was to investigate subendocardial viability ratio (SEVR) and ejection duration (ED) in children and adolescents with common cardiovascular risk factors such as arterial hypertension, obesity, and hypercholesterolemia.
METHODS: Four groups of pediatric patients were analyzed: 31 children and adolescents had hypertension, 36 were overweight, 49 were overweight and had hypertension, and 70 had hypercholesterolemia. The patients were compared to a control group of 50 healthy individuals. Subjects were sampled by opportunity sampling at the Department of Pediatrics Maribor, Slovenia. In each patient, blood pressure, anthropometrical parameters, and pulse wave analysis (PWA) measurements using applanation tonometry technique were performed and calculated.
RESULTS: The results show a statistically-significant difference in ED (p = 0.013) but not in SEVR (p = 0.074) in the hypercholesterolemia group in comparison to the control group. In other research groups, no statistically-significant differences were found. In all study groups, SEVR correlated significantly with age (positive, moderate) and heart rate (negative, strong) as well as with central mean pressure (CMP).
CONCLUSIONS: Our study does not show a significant role of SEVR and ED in early cardiovascular risk determination in children. However, some results do indicate a potential role of both, at least in hypercholesterolemia, and should be further investigated. .
