Active clinical trials for "Heart Diseases"

Monocytes may be separated into phenotypically and functionally distinct cell types by the presence or absence of the lipopolysaccharide receptor CD14 and the Fcγ-receptor CD16. The investigators hypothesize that the total numbers of CD16+ monocytes are significantly related to cardiovascular outcome in patients with angiographically proven coronary heart disease.

The purpose of the study is to study if coronary angiography cause cognitive dysfunction.

Congenital heart diseases (CHD) are the first cause of congenital malformations with an incidence of 8 for 1000 births. Within the two past decades prenatal diagnosis has had a great impact on CHD prevalence. France was the first country to show the impact of prenatal diagnosis on the lowering prevalence of the most severe CHD, the hypoplastic left heart syndrome. Since the 90's, great advances in pediatric cardiac surgery, intensive care and cardiac catheterization have led to lower mortality and morbidity in this population. Prevalence of " GUCH ", grown-ups with congenital heart disease has thus been significantly increasing. For all these reasons and as the investigators can also see in other many chronic diseases, new questions about the quality of life of these patients arise among patients, parents/future parents, doctors, patients associations, and public health organizations. In 2007 French government promoted a national public health plan for "improvement of the quality of life among patients suffering from chronic illnesses". First step of such a program is to correctly evaluate this quality of life. Indeed the concept of "quality of life" (QoL) remains subjective and difficult to appreciate and measure. Its analysis requires the use of validated questionnaires. Few questionnaires are available in Europe, especially in pediatrics. Few studies in this population have been led and no comparative study to a control randomized group has been published. The investigators study aims to analyze in the investigators tertiary care center in pediatric cardiology the QoL among 8 to 18 year old French patients with CHD using a validated questionnaire (Kidscreen™) and to compare it to same aged healthy children. The investigators secondarily intend to :- validate the French version of one reference pediatric QoL questionnaire used in most publications in the USA (PedsQL™). - compare the QoL to the severity of the CHD using a published semi-quantitative score.- compare the QoL to the severity of the CHD using the results of routine exercise tests (VO2 max) performed routinely in the investigators center. The investigators hypothesis are that :- Quality of life of most common and not severe CHD is close to that of healthy children. - QoL of severe CHD is not so well correlated to severity of CHD.- PedsQL™ is a simple questionnaire which can be used in France in routine follow-up of children with CHD.

In the present study the investigators test the hypothesis that the epidural anesthesia added on the general anesthesia is able to improve patient's outcome.

The purpose of this study is to evaluate CARDIAC MAGNETIC RESONANCE UTILITIES IN THE ISCHEMIC HEART DISEASE as topographical correlation between ischemic territory injury and coronary angiography.

Ultrasound (US) is widely used as a diagnostic tool in a hospital setting. In a medical department, diagnosis like heart failure or most kinds of heart diseases, hypervolemia, hypovolemia, pleural effusion, pericardial effusion, ascites, diseases in the gall bladder/bile tract, urine tract and venous thrombosis are common. US is the key diagnostic tool in these diagnosis, and on early diagnosis is crucial both on behalf of the patients well-being, and for hospital logistic reasons. The aim is to study the clinical use of pocket sized US as a screening diagnostic tool in an department of internal medicine. Method: All patients admitted (in certain preset periods) to Department of medicine will be screened with pocket sized US by expert user. Changes in diagnoses, as well as medications as a result of US screening will be the endpoints. US findings will be validated against standard echocardiography, or standard US/CT/MRI performed at the Radiological department. The aim is to study the clinical use of pocket sized US as a screening diagnostic tool in a department of cardiology. Method: All patients admitted (in certain preset periods) to Department of cardiology will be screened with pocket sized US for heart disease, pericardial and pleural effusion. Examinations by expert users. Specific findings could be myocardial dysfunction as heart failure, cardiomyopathies, regional dysfunction due to ischemia, valvular dysfunction, atrial enlargement, and pleural/pericardial effusion. Changes in diagnoses, as well as medications as a result of US screening will be the endpoints. US findings will be validated against standard echocardiography in all. As in 1), but examination by non-expert users compared to expert users.

A retrospective cohort study performed in the GPRD,UK. All patients with incident prostate cancer identified between 1 Jan 1999 and 31 Dec 2005 and a frequency-matched cohort of the general population will be followed- up for two outcomes; CHD including acute myocardial infarction or death from coronary heart disease and HF until Dec 31, 2006. Outcomes will be validated through requests to primary care physicians. Incidence rate´ratios of CHD and HF in the two cohorts will be calculated. In the cohort of prostate cancer the relative risk of CHD and HF associated with the use of bicalutamide compared to non-use will be estimated.

To estimate the rates of percutaneous coronary intervention (PCI) outcomes in patients after drug-eluting stents implantation who take statins.

The purpose of this study is to determine whether aspirin and clopidogrel resistance measured with Multiplate function analyser has a good correlation with incidence of major adverse cardiac events in patients with coronary artery disease (CAD).

To study the postprandial alterations in hemodynamics and blood pressure in relation to gastric emptying rate, postprandial blood glucose, plasma concentrations of insulin, satiety in healthy subjects.
