Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

MyHeart Counts is a smartphone-based mobile cardiovascular health research study. It will use the mobile health capabilities of smartphones and wearables to assess daily activity measures of the general public and compare these to measures of cardiovascular health - risk factors and fitness. How people divide their time among exercise, sedentary behavior, and sleep all affect cardiovascular health, yet largely go unmeasured. These can now be measured with sensors in phones or wearable devices as we have shown on iOS. With the large number of smartphone users addressable with a HIPAA complaint iOS \& Android platform, the investigators aim to collect activity and cardiovascular health data on many more subjects than in prior studies as well as provide much more quantitative data on type, duration, and intensity of daily activities. It also provides a platform to investigate methods to help participants increase heart-healthy activities. The study also includes a randomized controlled trial on physical activity. The overall goal is to develop an extensive source of data to help inform future cardiovascular health guidelines.
