Objective To evaluate ABI abnormalities and associated risk fators, we measured ankle brachial index (ABI) of cardiovascular- event high-risk patients. The first step enquiries the cardiovascular-event high-risk to win high limit of the ABI abnormality.
Methods We measured the ABI of 773 cases of hospitalised cardiovascular-event high-risk patients. ABI<0.9 and ABI>1.3 are defined as abnormal. Collected data and process statistics analysis to investigate the independent risk factors of ABI.
Results The incidence of abnormal ABI is 54%. Among them ABI<0.9 have 12.4%, Independent risk factors to predict ABI abnormalities are: sex, age, diabetes, creatinine abnormalities, mellitus, hypertension, high cholesterol, high smoking. In cardiovascular-event high-risk ABI<0.9 and ABI>1.3 all show obvious difference. TheABI no show obvious difference in difference clan.
Conclusions In patients with cardiovascular-event high-risk ABI<0.9 and ABI>1.3 are abnormal. ABI abnormalities are particularly prevalent in the old, smokers and patients with hypertension, diabetes or dyslipidemia. The difference of ABI between each clan did not show statistics to learn the difference.
