Abstract

Dyslipidemia is a well-established risk factor for cardiovascular diseases in the general population. However, this association is not observed in chronic kidney disease (CKD) patients. This study examines the association between lipid levels, including apolipoproteins A-I and B concentrations, and all-cause mortality or the development of new cardiovascular events in advanced CKD patients not yet on dialysis. This observational prospective historical study included 331 patients with CKD stage 4 or 5 not yet on dialysis. In addition to conventional clinical and biochemical data, total cholesterol, triglycerides, HDL, LDL, apolipoprotein A-I (apo A) and B (apo B) plasma concentrations were measured. Cox proportional hazard models were adjusted for age, sex, comorbidity index, residual renal function, serum albumin, C-reactive protein levels, and treatment with statins. The median follow-up time was 985 days, and during this period 105 patients died and 54 patients had a new cardiovascular event. In fully-adjusted fixed-covariate Cox models, the hazard ratio for each 10 mg/dl increase of apo A concentration was 0.915 (C.I. 95% 0.844 to 0.992; p=0,031). Patients with an apo A /apo B ratio in the upper tertile (i.e. > 1.42) had a b...Continue Reading

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
