THURSDAY, June 18, 2026 (HealthDay News) -- Smartphones and wearable devices are effective at increasing physical activity among patients with cardiovascular disease, according to research published online June 17 in the Journal of the American Heart Association.Ajith Kumar Vemuri, Ph.D., from the College of Medicine at Pennsylvania State University in Hershey, and colleagues conducted a systematic literature review to determine if interventions composed of smartphones and wearables are effective in enhancing physical activity among individuals with cardiovascular disease.Based on 14 randomized controlled trials (1,057 participants), the researchers found that interventions composed of smartphones and wearables resulted in a mean difference of 1,097.4 steps per day and 3.9 minutes of moderate-to-vigorous physical activity per day compared with control groups."Smartphones and wearables are already in people's pockets and on their wrists," Vemuri said in a statement. "When we show that these devices can effectively support routine care, we can start designing cost-effective, personalized digital interventions that reach a much wider population."Abstract/Full Text.Sign up for our weekly HealthDay newsletter
