OBJECTIVE: To determine a simplified method to identify presence of @entity4346 ( @entity4346 ) in pediatric populations because the relationship between heart growth and body growth in @entity1 has made indexing difficult for younger ages. STUDY DESIGN: Healthy @entity1 (n  =  400; 52% @entity1 , 0-18  years of age) from 2 different European hospitals were studied to derive a simplified formula. @entity1002 ( @entity1002 ) was calculated according to the Devereux formula. The derived approach to index @entity1002 was tested on a validation cohort of 130 healthy @entity1 from a different hospital center. RESULTS: There was a strong nonlinear correlation between height and @entity1002 . @entity1002 was best related to height to a power of 2.16 with a correction factor of 0.09. Analysis of residuals for @entity1002 /[(height(2.16))  +  0.09] showed an homoscedastic distribution in both sexes throughout the entire height range. A partition value of 45  g/m(2.16) was defined as the upper normal limit for @entity1002 index. As opposed to formula suggested by current guidelines (ie, @entity1002 /height(2.7)) when applying the proposed approach in the validation cohort of 130 healthy @entity1 , no false positives for @entity4346 were found (0% vs 8%; P  <  .01). CONCLUSIONS: Our data support the possibility to have a single partition (ie, 45  g/m(2.16)) value across the whole pediatric age range to identify @entity4346 , without the time-consuming need of computing specific percentiles for height and sex.
