There are few clinical areas more in need of innovation than heart disease. It's the leading killer among men and women in the US, accounting for one in every four deaths by the CDC's numbers, and yet it's also a body of health conditions that could be substantially mitigated through a number of lifestyle and behavior changes. So of course it's little surprise that cardiovascular health and care has long been in the crosshairs of digital health, whether it be in the form of fitness trackers, tele-rehabilitation and coaching programs, mobile ECG hardware, disease detection algorithms or any number of other novel approaches. Much like any other healthcare tools though, these novel approaches all need to win the approval of the clinical community before they'll begin to see meaningful use at scale -- and what better time to do so than one of the year's largest gatherings of cardiovascular clinicians, researchers, educators, program managers and vendors? MobiHealthNews was on-site last weekend at the American Heart Association Scientific Sessions 2019 in Philadelphia to check out posters, oral presentations and news from this year's show.
