Ventricular size increases during growth, but often due to @entity299 . This study aims to describe left ventricular dimension interrelations using a representation that is applicable to @entity1 with @entity299 , and subsequently to statistically study possible age and gender influences in a large population. In retrospect we analyzed echocardiographically obtained diameters of the left ventricle in 442 @entity235 of various breeds with congenital or acquired @entity299 . Also, we compared our findings with published data on @entity1 and other animals. Multivariate regression analysis was applied to assess possible influences of age and gender. A high correlation was found for end-systolic diameter (ESD) versus @entity998 ( @entity998 ): ESD (cm) = -1.01 cm + 0.93 x @entity998 (cm) with r = 0.94, p < .00001. Next, these @entity1 were categorized into three age groups (divisions at 3 and 7 years). We detected a slight age dependent effect: the regression coefficients for the younger group differed from the two older groups. No significant gender-related influence was detected. The observation of a high correlation for the ESD versus @entity998 relationship could be confirmed by reanalysis of published data on normal individuals and @entity1 @entity1 . The newly described relationship between ESD and @entity998 applies in particular to cardiac @entity1 . This is a relevant finding, because clinically important indices of ventricular performance generally depend on ESD, @entity998 or both. Thus, ESD versus @entity998 offers a convenient framework for studies on cardiac volume regulation and performance in the cardiopathological spectrum, while permitting incorporation of modulating effects related to age.
