Abstract：Objective To establish a convenient technique for detecting vascular stiffness based on photoplethysmography(PPG),and assess its clinical diagnostic efficacy.Methods A simplified technique for measuring arterial pulse wave velocity(PWV)was established by applying PPG combined with a portable handheld 12-lead electrocardiogram signal acquisition device.The simplified technique was applied in 55 patients hospitalized in Department of Cardiovascular Medicine of Chinese PLA General Hospital.A comparative analysis was conducted between the simplified technique and existing arterial stiffness detection technologies,and sensitivity,specificity,positive predictive value(PPV)and negative predictive value(NPV)were calculated,and the results were tested for consistency.Results The sensitivity,specificity,and accuracy of the wearable arteriosclerosis detection device was,respectively,85.7%,95.2%and 91.4%,with a great consistency(Kappa value>0.80).Conclusion The wearable device has the advantages of portability,simplification and quick in arteriosclerosis detection,and holds a promising application prospect in home and community.
