Consumer Wearable Devices in Cardiovascular Medicine

“The general population now has the capability to continuously track vital signs, exercise output, and advanced health metrics,” authors write in a review of the use of consumer wearable devices (CWDs) for tracking health and fitness. “Although understanding of basic health metrics may be intuitive (eg, peak heart rate), more complex metrics are derived from proprietary algorithms, differ among device manufacturers, and may not historically be common in clinical practice (eg, peak V˙O2, exercise recovery scores). With the massive expansion of data collected at an individual patient level, careful interpretation is imperative.”

The article includes critical appraisals of the health metrics provided by CWDs and the pitfalls in their interpretation. The authors also “provide recommendations for the interpretation of abnormal results, present the utility of CWDs in exercise prescription, examine health disparities and inequities in CWD use and development, and present future directions for research and development.”
