PURPOSE OF REVIEW: This review aims to assess the role of mobile health (mHealth) interventions and wearable technologies in the prevention and management of atherosclerotic cardiovascular disease (ASCVD). We sought to explore the benefits, challenges, and equity implications of these digital health modalities, with a focus on improving patient outcomes and reducing ASCVD risk. RECENT FINDINGS: Recent studies have shown that mHealth interventions and wearable devices effectively promote healthy behaviors, offer real-time physiological monitoring, and aid in the early prevention of ASCVD by targeting key risk factors such as metabolic syndrome and sedentary lifestyles. These technologies hold great potential for improving patient engagement and enabling timely interventions. However, challenges such as technological constraints, high costs, and gaps in digital literacy significantly hinder their broader adoption, particularly among disadvantaged populations. In summary, our findings highlight the critical need for accessible, affordable, and inclusive digital health solutions to prevent and manage ASCVD, promoting more equitable healthcare delivery. To maximize these benefits, future research should focus on harnessing artificial intelligence and digital markers to improve early event prediction and develop personalized preventive strategies.
