Abstract

Cardiovascular disease as a result of accelerated atherogenesis is common in patients with end-stage renal disease (ESRD). Dyslipidemia may be a major contributor in this process and can be influenced by lipid-lowering drugs (statins). Moreover, statins may exhibit additional inhibitory effects on the atherogenesis, such as a modulation of the immune system as triggered by oxidatively modified LDL and a reduction of the inflammatory marker C-reactive protein (CRP). We evaluated in a single-blind randomized trial of 28 ESRD patients on hemodialysis, the dose-depending effects of both atorvastatin and simvastatin on lipids, lipoproteins, LDL particle heterogeneity, high sensitive-CRP, and markers of in vivo LDL oxidation. Both statin therapies significantly lowered total plasma cholesterol and LDL-cholesterol concentrations to the same extent, whereas reduction in the concentrations of triglyceride-rich particles was less pronounced. Furthermore, statin therapy reduced LDL cholesterol in all LDL subfractions, without altering the overall LDL particle density. After both statins plasma hs-CRP concentrations were not significantly reduced; parameters of in vivo LDL oxidation (plasma ox-LDL concentration and the oxidation level of i...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.
