A look at the MyHeart Counts app and the potential of mobile technologies to improve human health

Keynote talks and presentations from the 2015 Big Data in Biomedicine conference at Stanford are now available on the Stanford YouTube channel. To continue the discussion of how big data can be harnessed to improve the practice of medicine and enhance human health, we’re featuring a selection of the videos on Scope.

At last count, the number of iPhone owners who have downloaded the MyHeart Counts app and consented to participate in a large-scale, human heart study had reached 40,000. The first-of-its-kind mobile app was designed by Stanford Medicine cardiologists as a way for users to learn about their heart health while simultaneously helping advance the field of cardiovascular medicine.

Built on Apple's ResearchKit framework, the app leverages the iPhone’s built-in motion sensors to collect data on physical activity and other cardiac risk factors for a research study. The MyHeart Counts study also draws on the strength of Stanford Medicine’s Biomedical Data Science Initiative.

At the 2015 Big Data in Biomedicine conference, Euan Ashley, MD, a cardiologist at Stanford and co-investigator for the MyHeart Counts study, shared some preliminary findings with the audience. Check out the full talk to learn more about how the app is helping researchers better understand Americans' health habits and what states have the happiest, most physically active and well-rested residents.

The scenario many of us learned in school is that two X chromosomes make someone female, and an X and a Y chromosome make someone male. These are simplistic ways of thinking about what is scientifically very complex.
