Personally, I wouldn't use/trust a bellsouth.net email address for any "official" corporate or other business communications- especially as related to a public traded company.
Company's in today's day and age maintain corporate owned/maintained web sites, and they do it for a reason. They also, nearly always list on said corporate site, the official path for "contact" or "corporate" communications. It's almost always (99% of the time) going to be an extension of the corporate web site domain name. When you have a main domain name, you get granted a block of email address to go with it- usually a 100 or more on even a "basic" web host plan. For $6 buck a month, the "daddy" site will host your web site and you get 500 email addresses to go with it, yep for $6 a month. In other words- when a biz or corporation has or pays to have a web site built and either a) hosted on their own servers or b) pays a legit hosting service a fee to host the site on their secure servers- you will always be granted a large block of email addresses to go along with that web site.
For example- all communications with Amazon will be in some form like servicedesk@amazon.com or investorinfo@amazon.com. All emails will end in the company web site domain. It's one of the common ways to spot a fake or phishing scam email from large companies. I've gotten things like replycustomer@4google.com or similar. That "4" being inserted is what makes it a 100% fake/phishing email.
The BHRT web site lists the following under the "contact" tab- and that's the only one I'd use/trust, again IMHO. bioheart@bioheartinc.com
Notice, it ends in the bioheartinc.com which is exactly what their main domain name is. That means it's a corporate owned, verified email address.
Sorry, but anybody can create a joeblow@bellsouth.net email via being on a bellsouth account. Not saying it's real or not- just VERY "uncustomary" for a company CEO to communicate on what, at best, would be a "personal", non corporate official email account. Again, the "standard" industry practice would be xyz@bioheartinc.com and EVERY email for every person or contact inside the company would be under that format.
My humble 2 cents.
