Smartphone Apps Help Heart Patients Walk More

Smartphone apps and wearable trackers help people with heart disease boost physical activity, a meta-analysis finds. Users walked 1,100 more steps daily and gained 4 extra minutes of exercise.

This news matters because it offers a cost-effective, scalable solution to a critical problem: many heart disease patients are not physically active, increasing their risk of further cardiovascular events. By leveraging devices people already own, digital interventions can overcome barriers like time, distance, and cost, making cardiac rehab more accessible. For patients, this means a practical tool to improve heart health and reduce mortality risk, without requiring expensive equipment or frequent clinic visits.
