AbstractBackground:Obesity and hypertension (HT) are well known cardiac risk factors. Our goal was to show that even if arterial blood pressure (BP) measurements of obese adolescents are normal during clinical examination, ambulatory blood pressure monitoring (ABPM) can be high, may include cardiac involvement and can also detect left ventricular mass indices (LVMI) value for obese adolescents to diagnose left ventricular hypertrophy (LVH).Methods:This study included 130 children (57 obese hypertensive, 36 obese normotensive, 14 normal weight hypertensive and 23 normal weight normotensive). Adolescents whose BP was measured during clinical examination, after 24-h BP was detected using ABPM, were examined with echocardiography for calculation of LVMI to determine cardiac risk factors for LVH.Results:There was a significant difference between the LVMI of obese-normotensive and obese-hypertensive adolescents, which showed the effect of obesity on LVMI independent of HT. Twenty (35.7%) of 56 obese adolescents with HT detected with ABPM had normal BP measurements during clinical examination. Dipper and nondipper features of obese adolescents were significantly higher in ABPM than those with normal body mass index. When the cutoff LVMI value for LVH was set at ≥38 g/mConclusions:Obesity is a risk factor for LVH independent of HT. To identify masked HT, 24-h ABPM and cardiac examination should be routinely performed in obese adolescents. Using a limit of LVMI ≥38 g/m

Objective Obesity has been linked to a spectrum of cardiovascular abnormalities from subclinical changes in cardiac structure to overt heart failure. Uncomplicated obesity (i.e. obesity without any other co-morbidity or cardiovascular risk factors) has been shown to cause increased LV mass and LV dilatation. Our hypothesis was that these changes are, at least in part, reversible following significant weight loss over one year. Method Forty-one obese (BMI 37.7 ± 7.4 SD) and 12 age, sex matched controls (BMI 21.6 ± 1.8 SD) with no identifiable cardiac risk factors underwent cardiac MR imaging for the assessment of LV Mass (g), LV end-diastolic volume (EDV; ml), stroke volume (SV; ml) and LV EF (%). Fourteen obese subjects underwent repeat imaging after a one year period of weight loss, averaging 14.6 ± 11.5 % total body weight. Results Obesity per se was associated with elevated LV mass (125 ± 27 vs 89 ± 23g; p<0.001), LV mass indexed to height (74.4 ± 14.3 vs 52.3 ± 11.4g/m; p<0.001) and EDV (147 ± 28 vs 119 ± 24 ml; p<0.001). ESV and SV were also elevated in obesity (47 ± 12 vs 39 ± 12ml; p=0.05, and 100 ± 14 vs 80 ± 18 ml; p<0.001, respectively). LV EF was similar between groups (p=0.83). After weight loss, there was a significant reduction in LV mass (by 16 ± 11g; 135 ± 31 vs 119 ± 28g; p<0.001), LV mass indexed to height (76.4 ± 15.7 vs 68.9 ± 12 g/m; p<0.001). EDV and ESV were significantly smaller after weight loss (146 ± 25 vs 133 ± 23 ml; p<0.001, and 43 ± 12 vs 41 ± 10 ml; p<0.001 respectively). LV EF and SV did not change significantly. Conclusion In subjects with obesity in the absence of identifiable cardiac risk factors, LV hypertrophy and LV dilatation were partially reversible after a one year period of weight loss.

The overall goal of this study was to determine race/ethnic differences in the associations between renal ET-1 and indices of blood pressure-related target organ damage in healthy adolescents. The subjects ranged in age between 15-19 years, had no history of any disease, and were not on any prescription medications. The 92 subjects consisted of 48 Caucasians (CA) and 44 African-Americans (AA). The two groups were similar with respect to height, weight, body mass index, blood pressure, ET-1), albumin excretion rate (AER), and left ventricular mass). Results: The CA’s were slightly older 17±1 v 16±1 (p=.02). The protocol was preceded by a 3 day self-selected sodium controlled diet of 250 mEq/day day which the subject picked up each day. The test day began with an echocardiogram for the assessment of left ventricular mass. Next, the subjects were seated for 60 minutes of rest during which the subjects consumed 200 ml of water. This was followed by the collection of a urine sample for the measurement of ET-1 and AER. Overall, ET-1 excretion was correlated with AER (r=.278), LV mass/ht 2.7 (r=.341), and systolic blood pressure (SBP; r=.365; p=.01 for each). The significant overall correlations were the result of significant correlations in AAs for AER (r=.344; p=.05), LV mass/ht 2.7 (r=.520; p=.01), and SBP (r=.645; p=.01) which were not apparent in CA’s. These findings suggest urinary ET-1 contributes to the development of BP-related target organ damage in AA youths prior to the development of increases in blood pressure.
