Filter by:This study will investigate the effect of PF-04950615, a new investigational lipid lowering agent, on LDL-C and other lipids.
Background: It is becoming increasingly clear that individuals from all corners of the globe use probiotic dietary approaches to enhance health. More recently, probiotics have shown promise in treating a variety of disease states, due to improved strain selection, stability and delivery technologies. Objective: The purpose of this study is to determine the lipid lowering efficacy of a probiotic supplement capsule containing Lactobacillus reuteri Cardioviva™, taken twice per day over 9 weeks, in subjects with hypercholesterolemia. Design: The study design is a double-blinded, placebo-controlled, randomized, parallel-arm, multi-centre study. The study will last a total of 13 weeks, including a 2-week wash-out period, a 2-week run-in period and a 9 week treatment period.
The purpose of this study is to investigate the cholesterol lowering effect of a drinkable low fat fermented milk enriched with plant sterol after 3 and 6 weeks of daily consumption in midly hypercholesterolemic people not treated by statins.
This study is being done to find out if tablets containing extended release (ER) niacin, laropiprant, and simvastatin (ERN/LRPT/SIM) are as effective as tablets containing ER niacin and laropiprant taken with simvastatin tablets (ERN/LRPT + SIM) for lowering high cholesterol and high lipid levels in the blood. The primary hypothesis is that ERN/LRPT/SIM 2 g /20 mg is equivalent to ERN/LRPT 2 g coadministered with simvastatin 20 mg in reducing low-density lipoprotein cholestrol (LDL-C).
This study will evaluate whether fasting/postprandial serum ApoB-48 levels are increased in diabetic participants compared to nondiabetic participants with the same range of serum LDL-C levels, and whether ApoB-48 levels can be used, along with LDL-C levels, to identify potential cardiovascular disease risk.
The purpose of this study is to compare the effects of pravastatin and rosuvastatin on coronary plaque characteristics in patients with stable angina pectoris.
Primary and secondary prevention trials with statins, as well as with antiplatelet, clearly demonstrated that these drugs are able to reduce cardiovascular events. Even if the principal mechanism of action of statins is to lower cholesterol, other effects, the so-called pleiotropic effects, have been considered as adjunctive properties potentially accounting for the anti-atherosclerotic effect of statins. Inhibition of oxidative stress may be considered an intriguing pleiotropic effect in view of the fact that oxidative stress is thought to be a key event in the initiation and progression of atherosclerotic disease. Reduction of several markers of oxidative stress including isoprostanes, 8-hydroxydeoxyguanosine (8-OHdG), and nitrotyrosine have been observed after statin treatment. NADPH oxidase is among the most important sources of reactive oxygen species involved in atherosclerotic disease. The investigators developed an ELISA to evaluate serum levels of soluble-gp91phox, the catalytic core of phagocyte NADPH oxidase. Recently the investigators showed that statins (30 days treatment) exert an antioxidant effect via inhibition of soluble gp91phox expression. The exact mechanism by which atorvastatin reduces NADPH oxidase, however, is unclear. Recent study showed that statin treatment inhibits leukocyte ROCK activity, a protein kinase implicated in the activation of NADPH oxidase, with a mechanism that seems to be independent from lowering cholesterol. To further study the mechanism(s) implicate in gp91phox downregulation by statin the investigators planned the present study in patients with high risk of vascular events such as hypercholesterolemic and Type 2 Diabetes mellitus patients. In addition the investigators want to evaluate the synergistic role of atorvastatin with aspirin treatment.
Objectives. - To evaluate the absolute and relative Lp(a) lowering effect of 1g/20 mg and 2 g/40 mg day of Niacin/Laropiprant in subjects with normal Lp(a) (< 30 mg/dL), high Lp(a) (30-60 mg/dL) and very high Lp(a) (> 60 mg/dL). - To evaluate the absolute and relative Lp(a) lowering effect of 1g/20 mg and 2 g/40 mg day of Niacin/Laropiprant depending on the number of kringle IV-2 repeated copies on the apo(a) gene. 2.1.1 Hypotheses. - The Lp(a) lowering effect of niacin is dependent of the pre-treatment Lp(a) concentration, with higher absolute and relative reduction in Lp(a) in subjects with hyperlipoproteinemia(a). - Lp(a) size, throughout modifying hepatic synthesis of apo(a), is a major factor related to the lowering effect variability of niacin in human.
The objective of this study is to investigate the accumulation of n-3 LC-PUFA (EPA, DPA and DHA) in human lipids by oral supplementation of ALA-rich linseed oil. In addition, the accumulation of n-3 LC-PUFA is compared between subpopulations of different age, gender and physiological conditions (overweight, increased serum total cholesterol).
Purpose: To demonstrate the efficacy of Beneflax™ flaxseed lignan (SDG) concentrate to lower serum cholesterol levels. Background: Flaxseed has been studied for various health benefits in humans, including prostate health, glucose control, and cardiovascular health. Cholesterol levels and high blood pressure are known to be risk factors for cardiovascular disease. Whole flaxseed has had variable effects on serum lipid levels, perhaps a consequence of variations in the amounts of secoisolariciresinol diglucoside (SDG) found in different flax cultivars, making the study of this bioactive compound difficult. Hypothesis: Flaxseed lignan (SDG) extract (Beneflax) significantly lowers total and LDL cholesterol. Flaxseed lignans also lower blood pressure and fasting glucose levels.
