Hongsawong N, et al. - This investigation looked at the prevalence and associated factors of renal dysfunction and proteinuria in patients with congenital cyanotic heart disease (CCHD). Researchers determined that microalbuminuria in the first decade of life can detect cyanotic nephropathy. In addition, high hematocrit (Hct) level and low platelet count were identified as predictors of microalbuminuria, and surgical treatment attenuated the risk for developing significant albuminuria.
