Ankle Brachial Index Combined With Serum Uric Acid Levels Improve Prediction All Cause Mortality and Cardiovascular Mortality in the Elderly Chinese Population

This study is a prospective community-based cohort study, which is aimed to investigate the prognostic factors, including conventional cardiovascular risk factors and measure ABI,SUA,asymptomatic target organ damage, for mortality and cardiovascular diseases. All population were separated into ABI ≤0.50，0.51 \<ABI ≤0.9，and 0.91 \<ABI≤1.40 three groups according to the ABI. ABI ≤0.9 was selected as cut point for the definition of PAD. Factors related to CVD and all-cause mortality, major adverse cardiac events (MACE) during follow-up was observed by multivariate Cox regression analysis and log rank test. Potential confounding variables with P \<0.10 were adjusted for multivariate analysis.
