Research Objective
Patients with chronic kidney disease (CKD) are at increased risk for atherosclerosis and peripheral artery disease (PAD). PAD has received far less
attention than coronary artery disease (CAD) in CKD patients. Few studies have examined risk factors for PAD in CKD. We studied the possible related risk factors and benefit of hypertension treatment in CKD patients with PAD.
Data Sources
We included 129 patients of both sexes with stages 3 to 5 of CKD, as described by the Kidney Outcome Quality Initiatives (K/DOQI ) classification, without
receiving dialysis therapy, not previously diagnosed with PAD.
Study Design
The following information were collected within six month period, including demographic characteristics, history of hypertension, anti-hypertension drug, diabetes, smoking, and pre-existing cardiovascular disease, body mass index (BMI), fasting blood glucose, HbA1c, total cholesterol, triglyceride(TG), high density lipoprotein cholesterol (HDL), low density lipoprotein cholesterol(LDL), calcium (Ca),
phosphate(P), Albumin, uric acid, urine protein. Ankle-brachial index (ABI) is a noninvasive diagnostic test that is efficient in detecting asymptomatic PAD with ABI
<0.9.
Findings
There were 22 (17.7 %) participants with PAD. Higher systolic blood pressure (SBP), higher diastolic blood pressure (DBP), higher pulse pressure showed strong association with PAD in CKD patients. On further analysis, significant fewer patients treated with calcium channel blocker (CCB) in hypertensive CKD patients with PAD (£q2 =7.055, p =0.008). The multivariate logistic regression analysis in hypertensive patients demonstrated the risk factors for PAD was pulse pressure, and Calcium channel blocker treatment may correlate with decreasing PAD formation (odds ratio= 0.232, 95% CI=0.07-0.73, p =0.013) in CKD patients.
Conclusion
There is a high prevalence rate of PAD in population of CKD, especially those with hypertension. ABI should be routinely examined in these patients who can benefit earlier from therapeutic measures.
