A novel parametric method-based nomogram of left ventricular internal diameters in normal Chinese adults.

ABSTRACT:

Background

Current echocardiographic normal reference values and nomograms in healthy adults are commonly normalized by body surface area (BSA) with simple linear or isometric corrections. However, various lines of evidence suggest this method might be flawed. In this study, we established the normative data of left ventricular internal diameter (LViD) by BSA-correlated regression equations with the calculation of Z-scores in healthy Han Chinese adults.

Methods

A total of 577 healthy Han Chinese adults were enrolled (age 44.4±13.0 years, 43% male and 57% female). LViD was acquired from two-dimensional-guided M-mode echocardiography on all participants from the parasternal long-axis view. Linear and nonlinear regression models were built to correlate LViD with BSA in differen
