Utility of Atherosclerosis Imaging in the Evaluation of High-Density Lipoprotein–Raising Therapies
نویسندگان
چکیده
Decreased level of high density-lipoprotein cholesterol (HDL-C) is a rigorous predictor for future cardiovascular events. Much effort is being made to develop HDL-C-raising pharmacotherapies in the attempt to avert the pandemic of atherosclerotic disease. Important properties by which HDL-C-raising compounds are effective involve improvement of cholesterol uptake from macrophages in plaque for transport back to the liver, improvement of endothelial function, and anti-inflammatory effects. Vascular imaging can aid in the determination which HDL-C-raising compounds are effective. Ultrasound and MRI have proved suitable for assessment of structural changes of the vessel wall. Ultrasound can also be used or assessment of endothelial function. 18F-fluordeoxyglucose positron emission tomography has opened up the possibility to assess vessel wall inflammation. In this article we discuss these various imaging techniques and how they can assess efficacy as well as provide pathophysiologic information on the mechanism of action of novel HDL-C-raising drugs.

Relationship between High-Density Lipoprotein and C-reactive Protein in Patients with Atherosclerosis
Abstract Background and Objective: Atherosclerosis is an inflammatory disease mostly caused by oxidation of low density lipoproteins (LDLs) while High-density lipoproteins (HDLs) oppose atherosclerosis by inhibiting the oxidation of LDLs. Serum concentration of C- reactive protein (CRP) also increases as an acute phase protein in inflammatory conditions like atherosclerosis. We aimed to evalu...
متن کاملThe Effect of Eight Weeks of High-intensity Interval Training on Lipoprotein-associated Phospholipase A2 and Lipid Profile in a Male Rat Model of Type 2 Diabetes
Introduction: Type 2 diabetes (T2D) causes hyperglycemia, hyperinsulinemia, and dyslipidemia, which are all risk factors for atherosclerosis. Lipoprotein-associated phospholipase A2 (Lp-PLA2) has been recognized as an indicator of atherosclerosis due to its role in vessel inflammation. This study aimed to investigate the effect of high-intensity interval training (HIIT) on serum levels of Lp-PL...

متن کاملResveratrol protects against diet-induced atherosclerosis by reducing low-density lipoprotein cholesterol and inhibiting inflammation in apolipoprotein E-deficient mice
Objective(s):Resveratrol (RES) is a polyphenol compound that has been shown a promising cardioprotective effect. However, some reports have yielded conflicting findings. Herein, we investigated the anti-atherosclerotic effects of RES in apolipoprotein E (apo E)-deficient mice on a high cholesterol diet. Materials and Methods: Firstly, atherosclerosis was induced by feeding a high cholesterol di...
