Comparison of arterial stiffness indices measured by pulse wave velocity and pulse wave analysis

AbstractObjective: Arterial stiffness indices measured by pulse wave velocity and pulse wave analysis have been widely studied in different populations. Only a few small studies have been reported regarding these two measurement methods. Therefore, the aim of our study was to compare the arterial stiffness indices measured by pulse wave velocity and pulse wave analysis in a randomly selected Chinese population.Methods: A total of 4285 subjects were recruited from Gaoyou County, Jiangsu Province, China. There were 2017 (47.1%) participants with hypertension. Pulse wave velocity was assessed by using a VP-1000 Automatic Arteriosclerosis Measurement System. Large artery elasticity and small artery elasticity were measured by pulse wave analysis with an HDI/PulseWave CR-2000 Research CardioVascular Profiling System using the modified Windkessel model.Results: Brachial-ankle pulse wave velocity, large artery elasticity and small artery elasticity were all significantly associated with the Framingham risk score...
