Active clinical trials for "Hypercholesterolemia"

The purpose of the survey is to evaluate the efficacy of treatment of hypercholesterolemia in Polish patients who are currently on lipid- lowering pharmacological therapy . Efficient treatment is defined as achievement of the LDL cholesterol level goals according to the European Society of Cardiology 2007 guidlines.

This Phase 1 study has been designed to evaluate the absolute bioavailability of PF-04950615 (RN316) in subjects with hypercholesterolemia who are not currently on lipid-lowering therapy.

This study is being done to provide valid data on the evolution of a cohort of French participants treated with ezetimibe, alone or in combination with a statin, to be used in simulation models for cardiovascular disease (CVD). Patterns of drug use, evolution of risk factors for CVD, cardiovascular morbidity and mortality, and goal attainment in low density lipoprotein cholesterol (LDL-C) levels over time will be analyzed.

This survey is conducted for preparing application materials for re-examination under the Pharmaceutical Affairs Laws and its Enforcement Regulation, its aim is to reconfirm the clinical usefulness of EZETROL® through collecting the safety information according to the Re-examination Regulation for New Drugs.

The objective of this study is to compare cholesterol absorption and metabolism after feeding diets naturally low or high in phytosterols. All meals will be prepared in a metabolic kitchen and analyzed for phytosterols. In a randomized crossover design a group of up to 25 healthy subjects will consume diets containing either 100 mg/day or 600 mg/day phytosterols for 4 weeks. At the end of each dietary period percent cholesterol absorption, fecal cholesterol excretion and LDL cholesterol level will be measured. The hypothesis is that LDL cholesterol and cholesterol excretion will be improved on the high phytosterol diet even though macronutrient composition, mineral intake and fiber consumption are similar.

To determine whether new 80 mg atorvastatin tablets are bioequivalent to 80 mg commercial atorvastatin tablets (Lipitor®).

The investigational drugs administered in this study activate proteins called PPARs. Data in the scientific literature on PPARs, as well as animal data and early clinical data generated by GSK with these drugs, suggest that activation of PPARs may cause the body to increase its use of fatty acids for energy, and lead to a reduction in body fat. There are also data to suggest a role for PPARs in regulating lipid (e.g., cholesterol) levels and inflammation. These and other activities of PPARs are being further explored in this clinical study.

Recent studies support the hypothesis that aortic stenosis (AS) develops due to atherosclerosis affecting the aortic valve endothelium. The study's aim was to assess Rosuvastatin on the hemodynamic progression and inflammatory markers of AS by treating low-density lipoprotein (LDL) in patients with AS according to the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATPIII) guidelines for one year.

A layer of cells called the endothelium line the walls of blood vessels. These cells produce substances that control the tone of blood vessels and thus control blood flow through the vessel. This regulating activity of the endothelium is dysfunctional in several diseases of the heart and blood vessels, including high blood pressure and high levels of cholesterol. Previous research has pointed toward a decrease in the action of nitric oxide (NO) as the cause of this abnormality. Nitric oxide is a substance produced by the cells of the endothelium that plays a role in the relaxation of blood vessels. In this project researchers plan to study blood flow through the blood vessels in patients forearms after receiving four different drugs: sodium nitroprusside, acetylcholine, L-NMMA, and aspirin. These four drugs act on the blood vessels of the forearm through different mechanisms. Acetylcholine and sodium nitroprusside are drugs that open the blood vessels of the forearm and increase blood flow through the vessel. L-NMMA is a drug that blocks production of nitric oxide (NO). Aspirin's role in controlling blood flow is unknown. Patients participating in this research study will not directly benefit from it. However, the study will contribute to researchers understanding of diseases of the blood vessels and heart.

To conduct a community-based research and demonstration project in cardiovascular disease prevention in the town of Pawtucket, Rhode Island. Targeted risk factors included high blood pressure, elevated blood cholesterol, obesity, cigarette smoking, and sedentary living. To evaluate the program, risk factor surveys on a cross-sectional and cohort basis were conducted along with mortality and morbidity surveillance both in Pawtucket and in the non-intervention comparison town of New Bedford, Massachusetts.
