Association of Synchronous Four-limb blOod pRessure and Pulse Wave velocIty With Cardiovascular Events

A National Registry for the Association of Synchronous Four-limb Blood Pressure and Pulse Wave Velocity With Cardiovascular Events in China

A multicenter prospective registry planned to recruit more than 100 000 patients 50 years old and older was carried out in China. This primary purpose of this study was to evaluate the association of synchronous four-limb blood pressure and pulse wave velocity with cardiovascular events. The secondary purpose was to evaluate the incidence rate,prevalence rate, value of diagnosis for peripheral arterial occlusive disease, and to follow up the effects of revascularization on cardiovascular events.

Although many studies with the correlation between synchronous four-limb blood pressure and pulse velocity measurement and cardiovascular outcomes have existed currently, the sample sizes are relatively small and the data on Chinese populations are lacking.Therefore, a multicenter prospective registry planned to recruit more than 100 000 patients aged 50 years old and older was carried out in China. This primary purpose of this study was to evaluate the association of synchronous four-limb blood pressure and pulse wave velocity with cardiovascular events in chinese populations. The secondary purpose was to evaluate the incidence rate,prevalence rate, value of diagnosis for peripheral arterial occlusive disease, and to follow up the effects of revascularization on cardiovascular events.
