    Angiogenic Factors and Risks of Technique Failure and Cardiovascular Events in Patients Receiving Peritoneal Dialysis.
    Cardiorenal Med 2016 May 31;6(3):251-9. Epub 2016 Mar 31.
    First Department of Internal Medicine, Nara Medical University, Kashihara, Japan; Department of Regulatory Medicine for Blood Pressure, Nara Medical University, Kashihara, Japan.
    Background: Placental growth factor (PlGF) is a member of the vascular endothelial growth factor family that acts as a pleiotropic cytokine capable of stimulating angiogenesis and accelerating atherogenesis. Soluble fms-like tyrosine kinase-1 (sFlt-1) antagonizes PlGF action. Higher levels of PlGF and sFlt-1 have been associated with cardiovascular events in patients with chronic kidney disease, yet little is known about their relationship with adverse outcomes in patients on peritoneal dialysis (PD).
