In order to evaluate the effects of hypertension on left ventricular (LV) anatomy and function, we investigated children on long-term hemodialysis using two-dimensional and M-mode echocardiography. The following echocardiographic estimations were made: indexed left atrial diameter (LAi) LV and diastolic diameter (LVDDi), inter ventricular septum (IVSi) and I.V posterior wall (PWi), with calculations of the LV mass index (massi), ejection fraction (EF), fractional shortening (FS), the velocity of circumferential fiber shortening (VCF) and wall stress (WS). LAi, LVEDDi, IVSi, PWi and massi were significantly higher in hypertensive patients than in normotensive and healthy children. EF and FS were significantly lower in both groups of dialyzed patients. The best correlation with mean arterial pressure had massi (r = 0.624), IVSi (r = 0.576) and PWi (r = 0.575). Those results suggest an important correlation between hypertension and concentric LV hypertrophy in long-term dialyzed patients.

UI MeSH Term Description Entries
D006973 Hypertension Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more. Blood Pressure, High,Blood Pressures, High,High Blood Pressure,High Blood Pressures
D007676 Kidney Failure, Chronic The end-stage of CHRONIC RENAL INSUFFICIENCY. It is characterized by the severe irreversible kidney damage (as measured by the level of PROTEINURIA) and the reduction in GLOMERULAR FILTRATION RATE to less than 15 ml per min (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002). These patients generally require HEMODIALYSIS or KIDNEY TRANSPLANTATION.
