[Biochemical risk factors for cardiovascular disease in children]. 
The problem of finding the biochemical markers for determining cardiovascular risk is complex, difficult and multidisciplinary.  Even in a simple biochemical blood test the number of possible variables significant for indicating the negative changes in the cardiovascular system is high.  The image created from a variety of factors is fuzzy, inconclusive and sometimes difficult to define and explain.  Contemporary cardiology uses fixed operative levels and the presence of biochemical factors as the basis for patient diagnosis.  Even a thorough and multi-biochemical analysis can not give conclusive results.  Many precautions are needed in using the results of biochemical analysis.  Ambiguous results may be misleading, disrupt the analytical process, or suggest probable, but not necessarily the correct, solutions.  This biochemical analysis presented points to the most important prognostic factors and biochemical information used in the cardiological treatment of children and adolescents.
