Hi there are a lots of scientific publications treating the indexations of left ventricular mass (LVM). I can link some abstracts, but the whole PDF documents are not public: - http://www.nature.com/jhh/journal/v23/n11/full/jhh200916a.html - http://www.ncbi.nlm.nih.gov/pubmed/11729247 or here https://www.stanford.edu/group/ccm_echocardio/cgi-bin/mediawiki/index.php/Left_ventricle_wall_thickness
It can be used to detect left ventricular hypertrophy. You can google "mass/height^2.7" to find more references.
