Filter by:This is a prospective, multi-center study examining the clinical impact of the Corus CAD (Age/Sex/Gene Expression score - ASGES) assay in approximately 250 evaluable subjects with no history of obstructive coronary artery disease who now present with chest pain or anginal-equivalent symptoms to a primary care physician (PCP) for evaluation.
The Cardiovascular Inflammation Reduction Trial (CIRT) is a randomized clinical trial investigating whether taking low-dose methotrexate reduces heart attacks, strokes, or death in people with type 2 diabetes or metabolic syndrome that have had a heart attack or multiple coronary blockages. This trial is funded by the National Heart, Lung, and Blood Institute (NHLBI)/National Institutes of Health (NIH).
Cardiac exercise rehabilitation consists of walking and bicycling activities. As the population requiring rehabilitation is aging, other forms of exercise may be useful and better tolerated. Tai Chi has been used for centuries, is easy to perform even by more debilitated individuals, and promotes improvement in blood pressure, fitness, and relaxation. Tai Chi may be more beneficial for frail cardiac patients because it is especially suited for the unfit and elderly, and can be practiced anywhere. Further studies are required to assess this form of exercise in cardiac patients. The objective of this randomized controlled study is to compare the effects of Tai Chi to "sham exercise" training in 200 frail cardiac patients who have completed six months of cardiac rehabilitation and are 60 years of age or older. Participants will be randomized to Tai Chi or "sham exercise" training and have their gait speed, blood pressure, heart rate, exercise capacity, balance, quality of life and cognitive function assessed before and after 24 week of training.
The primary aim of the PAL-HF trial is to assess the impact of an interdisciplinary palliative care intervention combined with usual heart failure management on health-related quality of life as measured by the Kansas City Cardiomyopathy Questionnaire and the Functional Assessment of Chronic Illness Therapy with Palliative Care Subscale.
The purpose of this study is to measure the INR (International Normalized Ratio) time percentage in the target zone (TTR: time in therapeutic range) of children benefiting from the AVK therapeutic education program.
This is a substudy of MARCH, in which we are exploring the changes in the vascular endothelium using pulse wave tonometry (a non invasive measure of cardiac health) to measure the changes in small and large arterial elasticity in participants of the MARCH study who switch to maraviroc-based regimens over 96 weeks of follow-up.
This study will examine if health benefits of consuming nutrient-rich apples, an apple extract and freeze dried apple product will be similar. 50 volunteers at increased risk of heart disease will consume either a low apple diet (<1 portion/d), 2 high or low polyphenol apples/day, an apple extract, or freeze dried apple granule product for 4 weeks (ten participants per group, randomly assigned). Apart from the extract group, all volunteers will consume a placebo. All volunteers will follow a low apple diet (<1 apple per day) other than what has been provided by the research team. Volunteers will complete food diaries at the start and end of the study and a number of questionnaires. Blood and urine samples collected at 0 and 4 weeks
The purpose of this study is to compare the cardiovascular profiles of efavirenz and rilpivirine, which are two drugs used to treat HIV infection.
Despite advances in the treatment of heart attacks the complications and death rates from failure of the heart to pump properly after treatment remain high. A heart attack occurs when one or more of the arteries that supply blood to the heart become blocked, causing the heart to be starved of oxygen and nutrients. This results in damage to the heart and so the the heart pumps less well. The main treatment for a heart attack is balloon treatment to open the blocked artery (called primary angioplasty). Whilst re-opening the artery is essential and allows blood to flow to the area of the heart starved of oxygen, this process also causes damage itself (called reperfusion injury) and increases the size of the heart attack further. Currently there are no treatments available that reduce this reperfusion injury. The investigators and others have shown that a substance called sodium nitrite reduces reperfusion injury in experimental models of a heart attack. The aim of this research is to perform a trial to investigate whether during a heart attack, an infusion of sodium nitrite into the damaged artery protects against reperfusion injury and reduces heart attack size in patients.
Females have a lower incidence of hypertensive and cardiovascular disorders that may relate to differences in nitrogen oxides in the blood and saliva. Some nitrogen oxides are recycled with the help of oral bacteria to nitric oxide which is protective against vascular disorders. This study will test the hypothesis that females have different numbers and species of these nitrogen-oxide reducing bacteria.
