The clinical value of the detection of peripheral arterial disease in type 2 diabetes mellitus patients with Doppler flow imaging survey meter

Abstract

Objective To assess the clinical significance of ankle-brachial index (ABI)in the diagnosis of peripheral arterial disease and its relationship with some interfering factors in type 2 diabetes mellitus. Methods One hundred and ten type 2 diabetes mellitus patients were selected.The systolic blood pressure and blood flow waveform in brachial artery,dorsal artery of foot or posterior tibial artery were surveyed with Doppler flow imaging survey meter ES-1000 SPM.ABI was calculated and the patients were divided into peripheral arterial disease group (group A) and non-peripheral arterial disease group (group B).Clinical data and risk factors were analyzed.Results In 110 patients,there were 20 cases (18.2%) with ABI<0.9.Age,TC,LDL-C,24 hours urinary microalbumin (24hUMA) and the prevalence of coronary heart disease were all higher in group A than those in group B (P＜0.05).LDL-C and the prevalence of coronary heart disease were independent risks variable for peripheral arterial disease. Conclusions ABI can assess objectively peripheral arterial disease in type 2 diabetes mellitus.which offers reliable base to active therapy.Advanced age,hypercholesteremia and hyper 24hUMA are the main factors of peripheral arterial disease.
