Key result
In adolescents with borderline and mild essential hypertension, nocturnal systolic BP correlated with left ventricular mass index (r=0.41, p=0.001), but diurnal BP fall did not differ from normotensives.
Why the study?
Does diurnal blood pressure variation differ between normotensive adolescents and those with mild essential hypertension with or without left ventricular hypertrophy?
Population
62 adolescents, including 33 normotensive and 29 untreated borderline and mildly hypertensive.
Comparison
Untreated borderline and mild essential… vs Normotensive adolescents
Design
Cross-sectional
Follow-up
24 hours

Nocturnal BP links to LV mass without reduced dipping in mild adolescent hypertension; challenges adult paradigms and leaves open youth-specific prognostic value.
Observational (n=62)
Does diurnal blood pressure variation differ between normotensive adolescents and those with mild essential hypertension with or without left ventricular hypertrophy?
Effect estimate: r = 0.41
p-value: p=0.001
Unlike in adults, adolescents with mild essential hypertension and left ventricular hypertrophy do not exhibit diminished diurnal blood pressure variation or altered renal functional reserve compared to normotensive peers.
Craig W. Belsha (1998) conducted an observational in Mild essential hypertension (n=62). Borderline and mild essential hypertension vs. Normotensive adolescents was evaluated on Correlation between nocturnal systolic BP and left ventricular mass index (LVMI) (r = 0.41, p=0.001). In adolescents with borderline and mild essential hypertension, nocturnal systolic BP correlated with left ventricular mass index (r=0.41, p=0.001), but diurnal BP fall did not differ from normotensives.
