Active clinical trials for "Heart Diseases"

To investigate the risk of major bleeding (including gastrointestinal and intracranial bleeding episodes) among new users of low-dose acetylsalicylic acid (ASA) in clinical practice

The health-related quality of life questionnaire "EQ-5D" has been collected in connection with several interventional and observational studies where the no-touch vein harvesting technique in CABG has been used. The results of the questionnaires will be compiled and reported in this study.

Cardiac output (CO) is an important parameter in the diagnosis and therapy of cardiac diseases. The current standard methods for the determination of CO, however, are either invasive (e.g. right heart catheterization) or technically expendable and expensive (magnetic resonance tomography, MRT). Therefore, the aim of the study at hand was to evaluate NICOM (bioreactance) as a new method for determinion of CO and to compare this new technique to MRT.

This study aims to evaluate the psychosocial situation of adult congenital heart disease (CHD) patients in terms of health-related quality of life, mental health, academic achievement, and employment status. By assessing a wide variety of medical (e.g., disease severity) and psychosocial (e.g., life events, coping strategies, personality) risk factors it will be possible to better understand the variables that influence psychosocial outcome of young adults with congenital heart disease. This will further improve the understanding of the lifelong consequences of a congenital heart malformation. Factors that proof to be predictors of favorable outcome represent a resource of resilience and therefore should play an important role in the care of CHD patients. By implementing those results in patient care the investigators aim to achieve an improved psychosocial outcome among adult congenital heart disease (ACHD). Hypothesis 1: It is expected that perceived health status, health-related quality of life and psychological adjustment will not differ between the patient and the control group. However, academic achievement and employment status are expected to be poorer in young adults with congenital heart disease compared to healthy controls. Hypothesis 2: It is assumed that parental socioeconomic status, problems in emotional regulation and impaired social support will be related to a negative psychosocial outcome and health-related quality of life. Moreover, the investigators hypothesize that disease severity is associated with academic outcome and employment status.

Infants requiring surgery in the neonatal period for complex congenital heart diseases are at risk for developmental problems. For infants with congenital heart diseases with admixture physiology and single ventricles, optimal circulation is associated with signs of adequate systemic perfusion and a systemic arterial oxygen saturation typically between 75% to 90%. Infants are often unable to withstand standardized developmental testing during early infancy due to medical fragility and sternal precautions after surgery. Evaluation of the quality of spontaneous movements and movement variability is a good alternative. The quality of general movements in early infancy is a valid predictor of neurological disorders in high risk infant groups and is assessed with short periods of video-recorded observations. This methodology has yet to be studied in infants with complex congenital heart disease that require surgery as neonates. For older infants, the Infant Motor Profile (IMP) is a promising tool to document developmental outcome.

Background: Non-alcoholic fatty liver disease (NAFLD) is the hepatic manifestation of the metabolic syndrome, which is one of the major risk factors of coronary heart disease (CHD). CHD is the most important manifestation of atherosclerosis, because of its immense morbidity and mortality. Transient elastography (TE, Fibroscan®) including the currently developed controlled attenuation parameter (CAP) is a non-invasive method for evaluation of liver fibrosis and steatosis, which is already implemented in routine care of patients with NAFLD. Hypothesis: The use of TE with CAP as screening for NAFLD might be an easy tool for risk assessment for CHD. Methods: Patients scheduled for routine coronary angiography will be screened for manifestation of NAFLD by TE including CAP, conventional ultrasound, clinical and laboratory parameters. Patients will be stratified for the presence of CHD based on the angiography results and correlation analysis with liver fat content will be performed. NFALD screening will be validated in a subgroup by MR-based measurements.

The aim of this study is to evaluate and describe the total coronary circulation time (TCCT) by using TIMI frame count method in patients performed coronary angiography. TCCT is described as an angiographic index which is the sum of the frame count of coronary artery and venous system. This study also evaluates the relationship between the diseases in arterial system such as coronary artery ectasia, coronary slow flow, coronary artery disease and coronary venous pathologies.

Background: - An acquired heart disease is one that a person gets after they are born. Two of these are rheumatic heart disease (RHD) and endomyocardial fibrosis (EMF). They are found more commonly in people who live in Africa than in other places in the world. Researchers want to learn more about these diseases. They especially want to know what role genes and other factors play in them. Objective: - To identify genetic risk factors for RHD and EMF in sub-Saharan Africa. Eligibility: Children and adults with RHD or EMF. Healthy volunteers over age 10. Design: Participants will come from existing study groups in Uganda and Nigeria. Participants may be required to provide a sample of their DNA. They will do this with either a blood or saliva sample or a swab of the mouth. Collected samples will be labeled with a code and sent to a lab in the United States for analysis. Remaining portions of participants samples will be stored for an unlimited period of time. They may be used in future studies. Some genetic and health information from participants might be placed into one or more scientific databases. Participant names and identifying information will be kept private. But there is a small chance someone could trace them from their genetic information.

This study investigates whether chronic heart rate reduction with ivabradine (Procoralan®, Servier, France) affects aortic compliance and endothelial function in patients with chronic stable coronary artery disease.
