Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this prospective study, the investigators aimed to evaluate the effects of improved hyperuricemia, a minor cardiovascular risk factor, on endothelial dysfunction in patients with chronic kidney disease.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Endothelial dysfunction (ED) is a key event in the development of atherosclerotic cardiovascular disease observed in patients with chronic kidney disease (CKD). Experimental models have shown that hyperuricemia causes hypertension and renin angiotensin system activation. In this prospective study, the investigators aimed to evaluate the effects of improved hyperuricemia, a minor cardiovascular risk factor, on ED in patients with CKD.
