Filter by:Metabolic syndrome (MetS) is highly prevalent all over the world. MetS is largely under-diagnosed in children and adolescents. Obesity and hypertension are two important requirements for criteria of MetS. With early detection and early intervention of MetS in children and adolescents will enable better care to reduce the heavy burden of health care all over the world. Investigators intend to recruit 150 children and adolescents age 6 to 18 yr with overweight/obesity or prehypertension/hypertension and 50 normal age-matched controls to reach the following research goals: 1) To identify biomarkers as risk factors; 2) To characterize that impact of vascular assessment in preMetS children; and 3) To examine the relationship among biomarkers, vascular assessment parameters, and metabolic phenotypes.
Statins are a class of cholesterol lowering medications that are prescribed for the prevention and treatment of cardiovascular disease. The purpose of this study is to determine if there is an increased risk of new diabetes when exposed to high potency statins, compared to low potency statins, among patients who had a recent cardiovascular event or procedure. The investigators will carry out separate population based cohort studies using administrative health care databases in eight jurisdictions in Canada, the US, and the UK. The cohort will be defined by the initiation of a statin, with follow-up until a diagnosis of incident diabetes or a prescription for insulin or an oral antidiabetic medication. The results from the separate sites will be combined in a meta-analysis to provide an overall assessment of the risk of new onset diabetes in subjects starting a statin.
The purpose of the study is to investigate whether long-term heat therapy (i.e. 8 weeks of hot tub 4-5x per week) improves biomarkers of cardiovascular health in young, healthy, able-bodied individuals. Although exercise is a potent means of improving cardiovascular health, many patients are unable to exercise effectively, and thus there is high demand for novel therapies to better manage cardiovascular risk in these patients. If successful, this study will set the groundwork for heat therapy to be used as an alternative treatment in patients who have limited exercise capabilities for the prevention of cardiovascular disease.
Coronary heart disease (CHD) is the leading cause of death in the United States; more than 600,000 Americans suffer a fatal cardiac event each year. Traditional CHD risk factors such as high blood pressure, smoking, and elevated cholesterol do not fully account for the timing and occurrence of CHD events and individuals with elevated levels of anxiety appear to have a greater risk of cardiovascular events. The present study will examine the impact of aerobic exercise and Lexapro in the treatment of anxiety and cardiovascular biomarkers among individuals with CHD.
The purpose of this study is to explore the role of lipoprotein(a) and apolipoprotein(a) phenotype in fatal and non-fatal cardiovascular disease (CVD) events risk in coronary disease patients divided on the basis of management strategy - medical, endovascular or open cardiac surgery.
Heart disease and strokes cause one in three deaths reported each year in the United States. Primary care practices need to implement new research findings that help decrease patients' risk for heart disease and stroke. This project will help to build primary care practice capacity for quality improvement and change management in small and medium size primary care practices in Colorado and New Mexico. This project will also help practices implement patient-centered outcomes research findings.
Electrical velocimetry (EV) is one of the latest adaptions of impedance cardiography showing diverging results. With electrode position being a suspected factor influencing measurement accuracy or reproducibility for impedance cardiography in general, no data is currently available on altering the gap of the two lower electrodes in EV. Reference values were determined using the non-invasive gold-standard cardiac magnetic resonance imaging (CMR).
This study evaluates the effects of different volumes of aerobic exercise training in cardiovascular parameters of patients with cardiovascular diseases enrolled in a cardiac rehabilitation program.
Research has shown that persons who have trouble sleeping and experience stress are at risk of developing heart diseases. Two treatments, called stimulus control instructions and sleep efficiency treatment, that do not involve sleeping pills, have been found effective in managing trouble sleeping. This study will be undertaken to find out if the two treatments are effective in improving sleep, and reducing stress and the risk of heart diseases. Persons with trouble sleeping may have a preference for either treatment. It is believed that if persons get the treatment they prefer, then they will be satisfied with the treatment and comply with it, and experience improvement in their sleep. This study will also examine the extent to which giving persons the treatment of their choice, as compared to giving persons treatment based on chance, will lead to higher satisfaction and compliance with treatment, and improved sleep. About 300 persons who experience trouble sleeping will be included in the study. They will be requested to complete a questionnaire and a sleep diary before and after they receive treatment, as well as 6 month and one year later.
Social determinants of health (e.g. the income, education, and environment of patients) may exert greater influence on health outcomes than traditional clinical factors (e.g. lab results, diagnoses, and family history). Calls for integrating primary care and public health are therefore increasing, but merging these domains of care is logistically difficult. Research is lacking on the incremental benefit of adding public health data at the practice level-- in improving either health outcomes or care delivery. This proof of concept pilot will merge data from electronic health records (EHRs) with community vital signs, a set of metrics that describes key community resources that affect health. The investigators will identify resource poor communities, or cold spots, based on four variables (education, poverty, life expectancy, and access to healthy foods) at the census tract level - referred to as a community vital sign. The hypothesis is that patients coming from cold spots are more likely to have worse health outcomes and that clinicians will deliver better care if they know a patient's community context and his/her specific social needs. This study will involve 12 primary care practices in Northern Virginia that care for more than 170,000 patients. Patient addresses will be geocoded for each practice and determine which patients reside in cold spots for each community vital sign. The variation for each community vital sign for each practice's patients will be calculated and a bivariate and regression analyses will be used to determine whether coming from a cold spot is associated with worse clinical quality metrics. 15 clinicians will be alerted when they see a patient from a cold spot, patients will complete a social needs survey, and clinicians will prospectively document through surveys whether such knowledge affects interpersonal interactions (such as time spent with patients and the use of clearer language) or clinical management (such as referrals to care coordination or community resources). By pragmatically integrating community vital signs into care, this innovative proposal will seek to understand which community data clinicians value, how these data might influence care, and how best to incorporate these data into clinical and population care.
