The Potential of Wearable Devices in Improving Cardiovascular Outcomes

Wearable devices show potential in improving physical activity levels of cardiovascular disease patients, but their use has limited correlation with other health factors, according to a systematic review of 20 studies. The most common uses of wearables were to improve physical activity, track changes in sleep, and gather data on various health indices. While devices are being developed to improve behavioral health components impacting cardiovascular health, they remain underdeveloped and lack utility, and further studies are required to determine their effects on cardiovascular health.

Cardiovascular diseases are one of the leading causes of death worldwide. A recent study reviewed the impact of wearable devices on cardiovascular health, including factors such as physical activity levels, waist circumference, obesity, glycated hemoglobin, and lipid levels. The study examined 20 articles, including systematic reviews, observational studies, case reports, and randomized controlled trials, and found that wearable devices can improve physical activity levels and have noted improvements in systolic blood pressure, waist circumference, weight loss, cholesterol, and diabetes control. While the devices are being developed to improve behavioral health components impacting cardiovascular health, they remain underdeveloped and lack utility. Researchers suggest that wearable devices serve more as a motivational tool for increasing physical activity rather than primary tools for improving health. Further studies are required to determine their effects on cardiovascular health and whether they would be applicable within the primary care setting. Meanwhile, research presented at the American College of Cardiology’s Annual Scientific Session Together With the World Congress of Cardiology in March showed the potential for wrist-worn sensors to determine troponin-I levels and obstructed arteries. These sensors detect the presence of troponin-I, which enters the bloodstream in the event of heart muscle damage, through infrared light located in the blood through the skin.
