Echocardiographic Measurements of Left Heart Chamber Size in a Large Cohort of Subjects: Comparison of Body Surface Area and Height Indexing to Account for Effects of Obesity

•Defining abnormal values by echo for cardiac structure in the obese is challenging.•Indexing left chamber size to BSA produces overcorrection in obese.•Height-indexed parameters were calculated for isometric and allometric models.•Absolute and indexed values are reported for >14,000 subjects without known CVD.•Unlike BSA, height indexing provided adequate body size scaling.
