As for the FDA... They're not that bad.... just usually very blinder focused. I really don't see them having an issue with this in terms of data collection. (I don't see apple supporting a portable pacemaker BlueToothed into an iPhone to get it's operational controls from some data center in lower elbonia).
and you'll be surprised that most of your medical procedure data is already in the cloud, if you used insurance or put your SSN on any form (The bad news about HIPAA is that it's 'portable'... often to the highest bidder ).

As for privacy/security issues...Noted. Data Interpretation... that's well outside of Apple's purview... I can't see Apple doing anything other than providing a secure end to end pipe. The back end, whether it be Johns Hopkins, or Joe's Appliance, and Blood Pressure monitoring will likely have to prove their system, including interpretation someplace. But raw data, in standard HLxx code, has to stand on it's own against the diagnostic standard in the HIPAA world. Non Issue (assuming the regulatory people validate it's to the HLxx standard).
