Another "small Heart" Study

[HopeSprings]

Many of us have had echocardiograms. Do you think the Dr. doing the test takes detailed measurements like those described in this study? Is this theory completely out? Just curious about your thoughts.

It might be a possibility in some patients with OI. A lot of members here have had echocardiograms which didn't reveal a reduced stroke volume, so I don't think this theory can apply to all OI patients.

Also one has to question the issue of causality. For instance a lot of people who have OI might be prone to not exercising, and if they don't exercise for a long time that might result in a diminished LV heart size through deconditioning.
