ABI and Risk Factors of Peripheral Vascular Disease in Maintenance Dialysis Patients: According to the Modality of Dialysis / 대한신장학회잡지

ABSTRACT

BACKGROUND: PVD is a risk marker for coronary disease, cerebrovascular disease and many other conditions. One of the simplest, noninvasive and most useful parameters to objectively assess PVD is the ankle-brachial index (ABI). The aim of our study was to explore the frequency, severity and the risk factors of peripheral vascular disease in dialysis patients, especially according to dialysis modality. METHODS: We studied 85 maintenance dialysis patients (HD 50 patients, PD 35 patients) and control (n=73) who has normal serum creatinine without DM, hypertension. ABI was tested during about 2 hrs into the hemodialysis by doppler ultrasono (Smartdop 30, HADECO, Japan). The severity of PVD was stratified into 3 groups based upon ABI [normal (0.9 or =55 yrs), duration of dialysis and HD were negatively correlated with ABI: r= -0.309; p<0.01 for HD modality. Multiple regression analysis demonstrated that HD modality (than PD) predicted ABI with an adjusted R2=0.206 and p<0.01. CONCLUSION: We conclude that ABI was significantly decreased in HD pts than PD pts. The frequency of severe PVD was significantly higher in HD pts than PD pts. These findings suggest that dialysis modality may be related to the severity of PVD in the maintenance dialysis patients. Further studies are needed to understand the association between PVD and nutrition factors, inflammation markers and dialysis- or uremia-related factors in maintenance dialysis patients.
