The Future of Wearables in Heart Failure Patients

The adoption of mobile health (mHealth) devices is creating a unique opportunity to improve heart failure (HF) care. The rise of mHealth is driven by multiple factors including consumerism, policy changes in health care, and innovations in technology. Wearable health devices are one aspect of mHealth that may improve the delivery of HF care by allowing for medical data collection outside of a clinician's office or hospital. Wearable devices are externally applied and capture functional or physiological data in order to monitor and improve patients' health. Most wearable sensors capture data continuously and may be incorporated into accessories (e.g., a watch or clothing) or may be applied as a cutaneous patch. Wearable devices are often paired with another device, such as a smartphone, to collect, interpret, or transmit data. This study assessed the potential applications of wearable devices in HF care, summarizes available data for wearables, and discusses the future of wearables for improving the health of patients with HF.
