Stroke due to intracranial arterial atherosclerosis is a significant medical problem, carrying one of the highest rates of recurrent stroke despite best medical therapy, with annual recurrence rates as elevated as 25% in high risk groups. The goal of this investigation is to advance a promising surgical treatment for symptomatic atherosclerotic intracranial stenosis - encephaloduroarteriosynangiosis (EDAS). The investigation will test in a phase II futility trial the potential of EDAS for further development before proceeding with the design of a definitive clinical trial of EDAS Revascularization in patients with Symptomatic Intracranial Arterial Stenosis (ERSIAS). The investigation is a 4-year futility trial to test the hypothesis that EDAS revascularization combined with aggressive medical therapy warrants further evaluation in a subsequent pivotal trial as an alternative to aggressive medical management alone for preventing the primary endpoint of stroke or death in patients with symptomatic intracranial arterial stenosis (Specific Aim 1). During the investigation the time course of collateralogenesis and perfusion improvement following EDAS will also be evaluated (Specific Aim 2.
This study is a randomised double blind placebo controlled trial comparing Rosuvastatin with placebo in HIV positive people who are at intermediate cardiovascular risk. It is possible that HIV positive people will receive a greater benefit from statins because of their higher baseline levels of inflammation. Current Australian guidelines recommend initiation of statin therapy on the basis of cholesterol level and the presence of other risk factors for heart disease (such as diabetes) but do not take into account whether a patient is infected with HIV. This study aims to determine what benefit HIV infected people will receive from starting statin therapy earlier then currently recommended.
The Physical Activity and Nutrition in Children (PANIC) Study is a single-centre controlled trial on the effects of a combined physical activity and dietary intervention on cardiometabolic risk factors and other health outcomes in a population sample of children from the city of Kuopio, Finland. The study provides novel scientific information for the identification of cardiometabolic diseases and other chronic diseases since fetal period and for the prevention of these chronic diseases since childhood. The main hypothesis of the PANIC study is that individuals at increased risk of cardiometabolic diseases and other chronic diseases can be identified in childhood and that it is possible to start the prevention of these chronic diseases by a long-term physical activity and dietary intervention since childhood.
The AtheroRemo-IVUS study aims to investigate the relation of coronary plaque phenotype and vulnerability as determined by intravascular ultrasound and near infrared spectroscopy with genetic profile and novel circulating biomarkers. AtheroRemo-IVUS is a prospective, observational, cohort study of patients who underwent coronary catheterization for acute coronary syndrome or stable angina pectoris. Prior to the catheterization procedure, blood samples were drawn for biomarker measurements and genetic analyses. Subsequent to the catheterization procedure, intravascular ultrasound is performed in a non-culprit coronary artery. In patients who are also participating in the AtheroRemo-NIRS substudy, near-infrared spectroscopy is additionally performed in the same non-culprit vessel. Primary endpoint is the presence of vulnerable plaque as determined by intravascular ultrasound. Secondary endpoint is long-term incidence of major adverse cardiac events. Results from AtheroRemo-IVUS are expected to improve our knowledge on the role of genetic profile and inflammation in the development of atherosclerosis and vulnerable plaques. Furthermore, novel biomarkers and intracoronary imaging techniques will be validated in this study.
Background: - Cardiometabolic diseases are medical disorders that can occur together and affect the heart. They increase the risk of developing heart disease and diabetes. One disorder, psoriasis, is an inflammation that mostly affects the skin but can affect the entire body. Another disorder, atherosclerosis, is a process in which cholesterol is gradually deposited on the wall of arteries. This causes arteries to harden and become less flexible. Many cells that cause psoriasis also cause atherosclerosis. Researchers want to look at the relationship between cardiometabolic diseases and psoriasis. Objectives: - To study the relationship between psoriasis and cardiometabolic diseases. Eligibility: - Individuals at least 18 years of age who have psoriasis. Design: - Participants will be screened with a physical exam and medical history. - Participants will have up to seven outpatient visits over the 4 years. The first visit will be a screening visit. Visits 2 will be12 months after visit 1. Visits 3, 4, and 5, will be scheduled yearly for the next 3 years. If participants have a psoriasis flare with more severe symptoms, they may have an extra visit. Those who leave the study early will have a final visit with the full series of tests. - At visits 1, 2,and 5, and any flare visits, participants will have a physical exam and medical history. They will provide blood and urine samples, as well as optional tissue biopsies. They will also have heart function tests. Imaging studies, as well as optional photographs of affected areas, will be performed. These tests will also be performed at the final visit. - At visits 3 and 4, participants will have a physical exam and medical history. They will also provide blood and urine samples, and have heart function tests.
- The prediction of extent and risk profile of coronary atherosclerosis based on clinical evaluation and non-invasive techniques. - Detailed analysis of plaque volume, plaque composition, risk plaque features and shear stress (WSS) changes during lipid lowering therapy (rosuvastatin 40mg) from 3D vessel reconstruction. - Prediction of changes in coronary arteries based on changes in non-invasive examinations. - Examination of WSS influence on atherosclerosis development and changes of WSS during lipid lowering therapy.
A computerized registry of cardiovascular disease patients in a large health maintenance organization in Israel. The registry is aimed to be used by health professionals to identify cardiovascular disease patients and to follow the courses of their illnesses and risk factors.
The potential for a drug interaction between Darapladib and Rosuvastatin is felt to be low and it would be helpful to quantify this risk in man in order to guide prescribing physicians. The primary aims of this study are to estimate the potential effects of repeat doses of Darapladib on the PK of Rosuvastatin as well as evaluating safety and tolerability. Two part approaches are planned for this study. Part A of the study will examine the effects of repeat doses Darapladib on the PK of Rosuvastatin in healthy volunteers of Caucasian descent. Based on whether a significant increase in Rosuvastatin exposure is observed in Caucasians in Part A, a decision will be made regarding whether to proceed with a conditional Part B to examine this effect in healthy volunteers of Far-East Asian descent. In both parts, subjects will receive Rosuvastatin 10 milligrams (mg) once daily (QD) for 1 day during the first treatment period (Treatment Period 1), followed by a 4 day PK sampling period/wash-out. Subjects will then receive darapladib 160 mg QD for the next 10 days with 24-hour PK sampling on the last day (Day 14 of the study). Immediately following this, all subjects will then receive the combination of Darapladib 160 mg and Rosuvastatin 10 mg for 1 day and continued Darapladib dosing of 160 mg QD for additional 3 days (Treatment Period 2) while blood samples are collected to assess Rosuvastatin PK. Plasma samples collected on Day 15 will be analyzed for both Rosuvastatin and Darapladib concentrations. Subjects will be required to return to the unit approximately 10 to 14 days following the last dose of study medication for a clinic visit for assessments and then will return again at 35 ±7 days following the last dose for the final follow-up visit of the study. The duration of each subject's participation in the study from screening to follow-up will be approximately three months. Approximately 18 evaluable subjects will be enrolled in Part A and another 18 subjects will be enrolled in Part B (if conducted) to complete dosing and all assessments.
This will be an open-label, single dose, single period study. Approximately 14 subjects will receive one dose of 250 mg of non-enteric coated SB-659032 following a low-fat breakfast. This study will evaluate whether SB-659032 has an effect on platelet function as determined by platelet aggregation tests using the agonists ADP and collagen. Blood samples for PK analysis and measurement of Lp-PLA2 activity will also be collected
