# Cardiovascular Risk Factors

This cross-sectional study analyzed 165,549 users across 34 Chinese provinces and cities who completed at least one valid smartwatch-measured pulse wave velocity (SW-PWV) reading on compatible Huawei watches between December 2020 and August 2022, of whom 35,402 completed the "Vascular Health" app questionnaire; SW-PWV correlated positively with age (r=.6323), male sex and BMI (r=.1981), was significantly elevated in participants with hypertension, diabetes, dyslipidemia, coronary heart disease, stroke and carotid plaque (with hypertension and carotid plaque showing the strongest correlations), discriminated prevalent cardiovascular disease with an AUC of 0.71, and at the guideline cfPWV threshold of 10 m/s showed 13.6% sensitivity and 96.
