Filter by:The UKPDS risk score is recommended to assess global risk for future coronary heart disease (CHD) events in primary prevention. Recently, high-sensitivity C-reactive protein (hsCRP) has emerged as a strong independent risk factor for CHD. 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) is a promising imaging technique for the evaluation of vascular inflammation that reflects vulnerable atherosclerotic plaque.
The purpose of this study is to evaluate the efficacy of motivational interviewing-based coaching to increase physical activity to achieve guidelines recommendations for cardiovascular disease prevention.
The purpose of this study is to assess the safety, tolerability, serum concentrations and pharmacodynamic effects on serum low-density lipoprotein (LDL) cholesterol of single and multiple subcutaneous and intravenous doses of BMS-844421 in healthy subjects (SAD) and in subjects with elevated cholesterol (MAD).
Low vitamin D levels were found to be associated with cardiovascular morbidity and mortality. Low zinc levels are associated with an increased atherosclerotic burden. Therefore we hypothesized that patients with pathological stress test would have low levels of Vitamin D and zinc compared to patients with a normal stress test.
A non-randomized, small vessel (SV) trial at approximately 15 sites in Japan to enroll 60 patients with a de novo lesion ≤28 mm in length (by visual estimate) in a native coronary artery ≥2.25 mm to <2.50 mm in diameter (by visual estimate). Approximately thirty patients will be randomly assigned to the angiographic subset to also undergo angiographic assessment after the 12-month clinical follow-up.
The purpose of this study is to compare coronary endothelium function in patients with a zotarolimus-eluting versus a sirolimus-eluting or a everolimus-eluting stents with optical coherence tomography, vasoconstriction in response to acetylcholine, and coronary biomarker level.
AIM III is a prospective, randomized, double-blinded, placebo controlled trial. The study is directly connected to IRB 08-008161 as a specific aim of the National Institute of Health (NIH) grant. Participants may either consent to and qualify for AIM I and AIM II (IRB 08-008161) or have a cardiac catheterization with acetylcholine testing in the Cardiac Catheterization Laboratory at Mayo Clinic in Rochester MN to be considered for this study.
We will study the hypothesis that long-term Tekturna treatment will improve endothelial function and the production and function of endothelial progenitor cells (EPCs) in patients with early atherosclerosis. Specifically, long-term Tekturna treatment will increase the Reactive Hyperemia Peripheral Arterial Tonometry indexes and increase the numbers and the function of circulating endothelial progenitor cells, compared to placebo, in association with a reduction in inflammation and oxidative stress.
Background: - Atherosclerosis, the arterial plaques or blockages that cause heart disease, develops in many people by the time they are in their mid-20s. The rate of atherosclerosis in patients with immune system disorders has not been well studied, but it may be very different from the general population. - Patients with chronic granulomatous disease (CGD) produce less of a group of molecules known as free radicals, which help to fight infection and may play a role in the development of atherosclerosis. Patients with CGD may develop atherosclerosis much more slowly than people without CGD. On the other hand, carrier mothers of children with genetically-linked CGD often have problems with autoimmune problems in addition to a problem with making free radicals. Patients with other immune system disorders also have very different responses to infection, and many of them also have autoimmune-like problems that may change the risk of developing atherosclerosis. Objectives: - To study the prevalence of atherosclerosis in patients with immune system disorders, compared with healthy individuals. Eligibility: - Individuals at least 18 years of age who either have been diagnosed with an immune system disorder or are healthy volunteers. Design: - The active part of the study involves one or two visits to the National Institutes of Health Clinical Center for a series of imaging tests and scans. - Participants will have the following tests during the active part of the study: - (1) CAT scan to obtain images of the chest arteries and measure the amount of calcium in the artery walls. - (2) Magnetic resonance imaging scan to obtain images of the coronary and carotid arteries in the chest and neck. - (3) Electrocardiogram to provide data on current heart function. - (4) Blood samples to provide data on heart, kidney, and immune system function. - Participants will be contacted every 2 years in the future for up to 30 years to determine whether they have developed heart disease. Researchers will ask participants to provide contact information for two other people who may likely know how to get in touch with the participant in the future.
In patients with chest pain or shortness of breath who are referred for stress imaging tests (either stress echocardiography or stress nuclear testing), the investigators seek to compare impact of using cardiac CT scans of the heart arteries to the stress test that their doctors ordered.
