Cardiovascular disease (CVD) is the leading cause of death and disease burden globally. Improving reach, access, and effectiveness of postdischarge care through cardiac rehabilitation and secondary prevention strategies is an international priority. The current proliferation of mobile technology has resulted in widespread development and availability of digital health interventions that can reduce cardiovascular risk. Text-messaging programs and apps have been shown to improve health outcomes. Other areas of research investigating the use of wearable devices are still emerging but lack robust data. Mobile and smartphone ownership is increasing among older populations, and digital health is not limited by age.
