The association between the increase in pulse pressure and renal function in chronic kidney disease patients with dyslipidemia.

In recent years, an association between chronic kidney disease (CKD) and arteriosclerosis has been identified. Pulse pressure (PP) is used as an index of arteriosclerosis. However, there have been few studies of the relationship between PP and renal dysfunction in patients with CKD. Therefore, we examined the association of increased PP on renal function in patients with CKD and dyslipidemia. This study included 104 patients with CKD who were diagnosed with dyslipidemia and commenced on drug treatment. In the present study, patients with PP ≥65 mmHg were included in the High PP group, and patients with PP <65 mmHg were included in the Low PP group. We compared the High PP group with the Low PP group about background patient characteristics, laboratory data and antihypertensive medications and type. Mutiple logistic regression analysis identified estimated glomerular filtration rate (eGFR) as a significant predictor of PP ≥65 mmHg. In addition, values of BUN, Ccr, and eGFR baseline and 12 months later were compared. In the High PP group, compared with baseline, BUN increased significantly and Ccr and eGFR decreased significantly after 12 months later. We consider that PP may be an auxiliary indicator of generalized arterial sclerosis and renal function.
