Hyperlipoproteinemia A as a Marker of Cardiovascular Risk in Patients With Stage 4 Chronic Kidney Disease
An observational study of CKD and Cardiovascular Diseases, run by Centre Hospitalier Universitaire de Nīmes at 1 site in France.
Trial summary
The blood level of lipoprotein A (Lp(a)) is linked to mutations in gene 6 and is associated with atherothrombotic risk and clinical manifestations such as myocardial infarction, ischemic stroke, and aortic valve calcification and stenosis. Several studies show an increased cardiovascular risk for a level >125 nmol/L. Read more about this study

About this study
Official title: Etude de l'hyperlipoprotéinémie A Comme Marqueur de Risque Cardio-vasculaire Chez Les Patients Atteints de Maladie rénale Chronique au Stade 4
The blood level of lipoprotein A (Lp(a)) is linked to mutations in gene 6 and is associated with atherothrombotic risk and clinical manifestations such as myocardial infarction, ischemic stroke, and aortic valve calcification and stenosis. Several studies show an increased cardiovascular risk for a level >125 nmol/L. Patients with severe chronic kidney disease (CKD) or on hemodialysis are at high cardiovascular risk, and Lp(a) levels would allow for better reclassification of this cardiovascular risk in the general population.
The study authors wished to the heterogeneity of the Lp(a) level in the population with CKD stages 4 without renal replacement therapy and to identify whether a high Lp(a) level is associated with cardiovascular comorbidity defined by the presence of cardiovascular comorbidity after adjustment for known risk factors such as diabetic status, obesity, smoking, LDLc level and medical treatment for cardiovascular prevention (statins, etc.). Furthermore, they will evaluate whether there is a link between a high level (> 125 mmol/l) of Lp(a) at inclusion in the cohort and the occurrence of cardiovascular or renal events (i.e. death of cardiovascular origin or occurrence of MI, stroke, stage 4 peripheral artery disease (PAD) or initiation of renal replacement) over a follow-up period of 18 months which could raise questions about the benefit of a specific treatment which remains to be evaluated.
