❤️Need for a prospective international observational study #WASE was born

5/LV size & function measured LV linear dimensions, volumes, mass, EF,GLS @TOMTEC_IMAGING #echofirst #ASEchoJC

6/Findings:
LV dimensions & volumes are larger in males, while LVEF and GLS are higher in females. #ASEchoJC #Echofirst

7/ Findings:
Heart size by LVEDVi is same for blacks and whites but smaller for Asians (in fact largest difference b/w ♥️ is Indian and Australia in both sexes) #ASEchoJC

8/Findings: #WASE Upper Limit of normal LV size by Volumes Larger than current guidelines #ASEchoJC

9/Findings: Lower limit of Normal WASE EF was HIGHER than guidelines #ASechoJC : need to adjust lower cutoff of “normal ” upward in guidelines

10/“normal” Indexed LV dimensions(size) & Mass are higher in #WASE & guidelines should adjust downwards
