Filter by:Framingham Risk Score (FRS) included age, gender, body mass index (BMI), cigarette smoking, blood pressure, total cholesterol (TC), LDL-cholesterol (LDL-C) and diabetes mellitus (DM). Previously, Framingham cohort study and other study has confered patients with medium or high FRS had worse prognosis. However, the score list was tending to over-estimate risk in medium FRS or under-estimate risk in high FRS patients . For this reason, ACC/AHA cholesterol guidelines also recommend the use of additional markers to improve atherosclerotic cardiovascular disease (ASCVD) risk assessment and medical decision making. Meanwhile, the ABI, which was the ratio of systolic pressure at the ankle to that in the arm, was quick, easy and used to diagnosis and assess the severity of peripheral artery disease (PAD) in the legs. Several research have shown its low value as an indicator of general atherosclerosis and independently risk associated with cardiovascular events in prospective studies . In addition, ABI aggressively modified risk factors and accelerated the adverse prognosis of ASCVD. However, whether FRS or ABI, were all related to participants and race. And, most studies were from western countries, lack of Asian date, especially aimed at risk prediction model research. Therefore, this research was aimed to validate incorporating ABI and relevant Framingham risk variables whether could improve prediction all-cause mortality and cardiac mortality in medium and high Framingham risk score (FRS) patients.
Peripheral arterial disease (PAD) is a common clinical manifestation of the systemic atherosclerotic process, and the ankle brachial index (ABI) is an ideal tool to diagnose PAD. The association between high serum uric acid levels (SUA) and arterial stiffness as well as endothelial dysfunction has been demonstrated in humans and uric acid has been suggested to be an important modulator of the inflammatory process. It has also been confirmed by clinical studies. Currently, there have been few long term follow up studies focused on the whether serum uric acid levels combined with ankle brachial index can improve prediction all cause mortality and cardiovascular mortality,especially in China population.Therefore, the aim of this study was to elucidate whether ABIcombined with SUA can improve prediction all cause mortality and cardiovascular mortality in the elderly China population independently of the traditional Framingham Risk Score.
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.
