Filter by:The purpose of this study is to evaluate the acceptance of a salt restricted diet cooked with a controlled amount of salt in patients with heart disease. Verifying if there is difference in the acceptance of the standard and hyposodic diets cooked with controlled amount of salt.
The investigators will conduct an epidemiological analysis of data from the Women's Health Initiative to investigate the prospective association between chocolate intake and the risk of heart disease and stroke.
The investigators are interested in determining the best surgical technique to correct functional mitral regurgitation, as there is currently not one technique that is established to work better than the other. The technique used in current clinical practice is undersizing mitral annuloplasty (UMA), in which a prosthetic ring is implanted onto the mitral valve to correct the leakage. Though widely adopted, durability of the repair is less, as 58% of the patients present with recurrent FMR within 2 years. There are no specific algorithms to predict who might have UMA failure, but research indicates that some geometric indices might be strong predictors. The investigators are interested in testing the hypothesis that, elevated lateral inter-papillary muscle separation (IPMS) is a predictor of post-UMA recurrence of FMR at 12 months. In the first part of this study, the study team will measure lateral IPMS before surgery, and relate to post-surgery FMR severity at discharge/30 days, 6 months and 12 months. A relatively newer technique is papillary muscle approximation (PMA), in which a suture draws together the two muscles that connect the mitral valve to the heart muscle prior to performing UMA. This reduces the lateral inter-papillary muscle separation (IPMS) and is expected to improve the durability of UMA. In the second part of this study, the investigators will perform PMA and UMA together and determine if FMR severity is reduced at discharge/30 days, 6 months and 12 months.
Background: Heart disease is a major cause of illness and death in women. To understand better the role of estrogen in the treatment and prevention of heart disease, more information is needed about its effects on coronary atherosclerosis and the extent to which concomitant progestin therapy may modify these effects. Methods: The investigators randomly assigned a total of 309 women with angiographically verified coronary disease to receive 0.625 mg of conjugated estrogen per day, 0.625 mg of conjugated estrogen plus 2.5 mg of medroxyprogesterone acetate per day, or placebo. The women were followed for a mean (±SD) of 3.2±0.6 years. Base-line and follow-up coronary angiograms were were analyzed by quantitative methods. Follow-up coronary angiograms were obtained after an average of 3.2 years of follow up.
Strong Hearts for New York is a research study which aims to reduce cardiovascular disease (CVD), improve quality of life, and reduce CVD related health care costs in rural communities. Our aim is to better understand how changes in lifestyle can affect the health of rural women and others in their communities.
The Latino population in the United States is increasing in size; is diverse in culture, backgrounds and countries of origin; is experiencing unique influences from social and behavioral acculturation to the U.S.; is reported nationally to have lower rates of heart disease; is reported to have increased prevalence of diabetes and asthma; and is generally poorer and less educated (NHLBI working Group, 2003). They represent an important target population for disparities research. In particular Latinos accessing care in Community Health Centers in the United States represent an ideal population for conducting disparities research because lack of access to care is minimized through various governmental health insurance support mechanisms. This study will build on existing relationships to conduct the proposed study, using expertise in epidemiologic, behavioral and genetic research in an effort to promote a coordinated, comprehensive, interdisciplinary and focused research effort to improve the care being delivered to indigent Latinos at-risk for and with CVD.
Transcatheter Aortic Valve Implantation (TAVI) indications are progressing rapidly as an alternative to conventional surgery for aortic stenosis cure. Despite a high rate of procedural success, some patients do not benefit from the procedure. The investigators hypothesis is that aortic stiffness may be of major prognostic significance after stenosis relief. The aim of this study is to test the prognostic impact of aortic stiffness estimated by the volume of calcifications of the thoracic aorta on the CT-scan performed systematically before the procedure. This prognostic value will be assessed in 4 independent cohorts issued from 4 french cities (Lyon, Rouen, Paris, Clermont-Ferrand).
The investigators will conduct a randomized controlled trial that aims to compare the incidence of contrast-induced nephropathy between transradial- and transfemoral-access cardiac catheterization.
In 2010 there was published new European recommendations for assessment of adult and elderly men and women, who want to start with physical activity and/or participate in endurance contests. In this study we want to test if a group of people with positive score on a self-reported questionnaire and/or high-risk score in a risk scoring system (NORRISK) have more undetected heart diseases than a control group with no reported or detected risk factors.
A novel magnetic resonance (MR) compatible accelerometer for respiratory motion sensing (MARMOT) has been developed as a surrogate of the vendors' pneumatic belts. The aim is to model and correct respiratory motion for free-breathing thoracic-abdominal MR imaging and to simplify patient installation.
