The purpose of this study is to determine the impact of alcohol consumption in diurnal triglyceridemia in a free living situation.
The purpose of this study is to determine how a stress reduction program, called Mindfulness Based Stress Reduction (MBSR), compared to a health education program, improves well being and reduces the risk of heart disease in women Veterans. Recruitment completed.

The course of both pulmonary embolism (PE) and one of its more relevant late complications, i.e. chronic thromboembolic pulmonary hypertension (CTEPH) is still substantially unknown. Recent evidence has shown that the incidence of CTEPH is higher than previously believed, but this has not been confirmed by other studies. A clear link between PE and CTEPH has been questioned by some experts. A great number of patients affected by PE persistently have residual chronic thromboembolic material the meaning of which is a matter of debate. The evidence sustaining a link between chronic residual PE and subsequent PE recurrences or CTEPH is insufficient. Thus, a nationwide, multicentre, prospective cohort study was designed with the following aims: 1. to ascertain the incidence of symptomatic CTEPH after a first episode of acute PE; 2. to ascertain the incidence of venous thromboembolic (VTE) recurrences after a first episode of acute PE; 3. to evaluate whether a relation exists between chronic residual PE and CTEPH 4. to evaluate whether a relation exists between chronic residual PE and VTE recurrences; 5. to evaluate whether a relation exists between persistent right ventricular dysfunction and CTEPH; 6. to evaluate whether a relation exists between persistent right ventricular dysfunction and PE recurrences. For each enrolling centre, consecutive outpatients or inpatients with an objectively diagnosed first acute PE episode are considered eligible.
Elderly patients are the fastest growing surgical population and have an increased risk of postoperative cardiac problems. Diastolic dysfunction, or the reduced ability of the heart' s ventricles to fill completely, is common in the elderly population and increases the risk of major adverse cardiac events after surgery. This study will measure diastolic filling and implement fluid and drug management during surgery to determine whether this reduces serious cardiac events related to diastolic dysfunction after surgery in this high-risk population.
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.
This is a in-vitro study to evaluate the pharmacodynamic interaction between ticagrelor and its active metabolite (AR-C124910XX) and their effects on the pharmacodynamics of salicylic acid. The study consist of two parts of in-vitro study as follows; - Part 1 : in-vitro study to evaluate the pharmacodynamic interaction between ticagrelor and its active metabolite. - Part 2 : in vitro study to evaluate the pharmacodynamic interaction between ticagrelor and its active metabolite and their effect on the pharmacodynamics of salicylic acid on platelet aggregation tests with the agonist of arachidonic acid.
Hypertension and endothelial dysfunction are being increasingly recognized as key etiological factors in the development of atherosclerosis and subsequent cardiovascular disease (CVD). A substantial body of evidence indicates that treating patients with elevated blood pressure (BP) leads to marked reduction in the risk of stroke, myocardial infarction, heart failure, and renal failure. There is also accumulating evidence associating endothelial dysfunction, which is defined as incapacity of the arteries to vasodilate when required, to elevated BP and an increased risk of CVD. While there are more and more studies on how diet affects BP in healthy subjects, the impact of dairy consumption per se on both endothelial function and ambulatory BP has not been well characterized in patients with established essential hypertension. Therefore, the general objective of the study is to investigate in a single-blind randomized controlled study the impact of dairy consumption on ambulatory BP and endothelial function in subjects with mild to moderate essential hypertension.
The purpose of this study is to find out if starting anti-retroviral therapy (ART) above 500 cluster-of-differentiation-4 (CD4)+ cells/milliliter (mL) ('early ART group') is better at reducing the stiffness of arteries than waiting to start ART until the CD4+ drops below 350 cells/mL ('deferred ART group'). Artery stiffness has been associated with an increased risk of cardiovascular (heart) disease, and could be useful as an earlier indicator of heart disease. In this study, the stiffness of arteries will be measured at study entry, months 4, 8, 12, and annually thereafter, using a tonometer on the participant's forearm.
