HDL and CETP in atherogenesis

Deutsche medizinische Wochenschrift

Despite optimal treatment of high low density lipoprotein (LDL) cholesterol with statins many cardiovascular events are not prevented. Additional therapeutic strategies are required to reduce the residual cardiovascular risk. Large epidemiological studies show an inverse correlation between the plasma concentration of high density lipoprotein (HDL) cholesterol and the incidence of cardiovascular events. Under physiological conditions, HDL is vasculoprotective and mediates the reverse cholesterol transport. However, new studies suggest that HDL particles represent a heterogeneous population. Under several pathophysiological conditions, HDL was shown to promote atherogenesis and inflammation. Interventional studies and metaanalyses examining the effect of increasing HDL cholesterol have reported mixed results. Inhibition of cholesteryl ester transfer protein (CETP) is a new and potent strategy to increase HDL concentrations. However, the first CETP-inhibitor torcetrapib increased blood-pressure and increased cardiovascular events despite increasing HDL. The blood-pressure increasing effects are not known for more recently developed CETP inhibitors such as dalcetrapib and anacetrapib nor in patients with genetic CETP deficiency. A...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.

Atherosclerosis Disease Progression

Atherosclerosis is the buildup of plaque on artery walls, causing stenosis which can eventually lead to clinically apparent cardiovascular disease. Find the latest research on atherosclerosis disease progression here.
