Active clinical trials for "Hyperlipidemias"

Background: - Heart disease is the leading cause of death in the United States. Eating fruits and vegetables with chemicals called flavonoids may protect against heart disease and improve blood flow to the heart. They are found in blackcurrant berries. Oils found in fish and mussels called omega-3 fats have also been shown to protect the heart. Researchers want to know if blackcurrant extract and omega-3 fats can improve blood flow, which may increase blood to the heart. They also want to learn about the health of blood vessels and how the heart works. Objective: - To learn if blackcurrant extract and omega-3 fats will improve blood flow and make the heart beat stronger. Eligibility: - Healthy adults 55 to 75 years old. Design: Participants will be screened with medical history, physical exam, and blood tests. Visit 1 will take 6 7 hours. Participants will have physical exam and blood and urine tests. A small device like a microphone will be placed on their arm to take pictures of blood vessels. A blood pressure cuff will be tightened on their arm and more pictures will be taken. Blood pressure cuffs will be placed on their arms and legs. They will be tightened at the same time and blood pressure will be measured. Participants will answer questions about their eating and exercise. Every 8 weeks, participants switch from taking blackcurrant and/or omega-3 tablets to a placebo to no tablets. <TAB> Every 8 weeks, they will have another shorter clinic visit that will repeat most of visit 1.

To search for the genetic cause of the metabolic syndrome, a lipid disorder that poses a major risk for coronary heart disease.

Purpose: The mechanism of most of the multifactorial chylomicronemia (MCM) remains elusive. In order to decipher the mechanisms involved in the occurrence of this disease, plasma TG lipolysis characteristics will be monitored for 60 minutes after heparin injection instead of the 10 minutes gold standard, in a large group of genotyped MCM patients.

Review of clinical characteristics of patients who are prescribed Repatha® and how their treatment is managed.

The purpose of this survey is to determine the incidence rate of cardiovascular (CV) events associated with long-term treatment with and without omega-3 fatty acid ethyl esters (Lotriga Granular Capsules) in high-risk hyperlipidemic patients treated by statin in daily medical practice.

Familial Hypercholesterolemia is a common cause of premature coronary heart disease, it is present in 1 per 500 to 1 per 250 people of the general population. Studies on families of Hypercholesterolemia have shown that children with Hypercholesterolemia have a major increase in risk of coronary heart disease after the age of 20. The difference between Hypercholesterolemia and normal children in their atherogenic profil begin at the age of Nowadays , systematic screening techniques are not well implemented whereas their are clear World health organization guidelines. International studies show treatment must be initiated early as at the age of eight years old. In pediatry, Parents can be reluctant to practice blood test on their children. In order to allow more patients to be diagnosed and treated early enough to prevent major complications we need to find an non invasive test. The main objective is to define the level of detection of cholesterol in saliva with two enzymatic tests. Furthermore we aim to evaluate the performance of salivary detection of cholesterol in children.

The purpose of this pilot study is to determine if, during pregnancy, women with GDM have an exaggerated lipid response compared to non-gestational diabetics. If a difference is noted, further studies will explore the possibility of screening gestational diabetics during their pregnancy for hyperlipidemia to determine if prenatal screening can predict postpartum risk for hyperlipidemia. In addition the relationship, if any between maternal lipid dysfunction and placental disease will be explored. This will be a prospective cohort study. As part of routine prenatal care, women receive a one hour glucose challenge test to screen for gestational diabetes. Those women with elevated values then require a three hour glucose tolerance test, which is a diagnostic test for gestational diabetes. All women that are scheduled to receive a three hour GTT will be identified and ask to enroll in this study. 46 women whose three hour GTT is normal and thus do not have GDM, will be compared to 46 women with an abnormal three hour GTT and thus would have the diagnosis of GDM. Enrolled women will have a lipid panel consisting of; total cholesterol, triglycerides, HDL and LDL cholesterol at the time of their fasting glucose blood sample. In addition, a repeat lipid panel will be sent at the time of the third hour sample, to assess changes, if any due to the glucose challenge. Umbilical cord blood samples will be sent in order to obtain newborn lipid profiles. Women in both the GDM and normal groups will be asked to return 6-8 weeks

This study will determine the usefulness of magnetic resonance imaging (MRI) for examining the heart or blood vessels. MRI uses a magnetic field and radio waves to produce images of body tissues and organs. The subject lies on a table that can slide in and out of the scanner (a metal cylinder), wearing earplugs to muffle loud noises that occur during the scanning process. MRI of the heart and blood vessels, called magnetic resonance angiography (MRA), is a developing diagnostic method that permits evaluation of arteries and veins without the use of x-rays or invasive catheterization required by conventional angiography. People 18 years of age and older with known or suspected atherosclerotic disease may be eligible for this study. Participants have blood tests and MRA scanning. The MRA takes about 1.5 to 2 hours. During part of the scan, a contrast agent may be injected into a vein to brighten the images of the heart and blood vessels. Subjects are monitored with an electrocardiogram and are asked to hold their breath for about 5 to 20 seconds intermittently during the procedure. A CT scan may be done to confirm the MRA findings. CT uses x-rays to produce pictures of the heart and blood vessels. The subject lies on a bed during the scan and is given a contrast agent through a catheter inserted into a vein. Subjects are asked to hold their breath intermittently for about 5 to 20 seconds. A medicine called a beta blocker may be administered to slow the heart rate.

Researchers plan to study the fat-rich particles, called lipoproteins, which circulate in the blood. This study is designed to improve understanding of normal, as well as abnormal, lipoprotein metabolism and the role it plays in the development of hardening of the arteries (atherosclerosis). Patients participating in this study will receive injections of lipoproteins or apolipoproteins (the protein component of lipoproteins) that have been isolated and purified. These lipoproteins will be labeled with small amounts of radioactive material and sterilized before they are injected into the patient. Patients participating in the study will be required to have blood samples taken, and provide urine samples throughout the course of the study. In addition, patient will be required to follow a specially formulated diet. Patients will be weighed throughout the course of the study....

To explore whether there is a difference in the rate of tendon tear after hyperlipemia in tennis elbow patients and those with normal blood lipids after closed treatment, which provides clues for further exploration of its mechanism. 1. Collect data from 108 cases of tennis elbow patients treated at the Institute of Sports Medicine, Peking University Third Hospital from January 2010 to December 2018 at the Institute of Sports Medicine, Peking University Third Hospital. Statistics included the sex, age, BMI, number of closures, total cholesterol, triglycerides, low-density lipoprotein, high-density lipoprotein. 2. Retrieve the MRI imaging data of the above-mentioned patients, and use the extensor tendon at the humerus to see if there is a tear as an observation indicator. Analyze the difference of tendon tear after closed treatment in patients with high blood fat and normal blood fat.
