Active clinical trials for "Heart Diseases"

The purpose of this study is to determine vaccination coverage of recommended vaccines (routine childhood vaccines and vaccines against seasonal flu and pneumococci) in children with chronic diseases (allergy, cystic fibrosis, diabetes mellitus type 1, congenital heart disease, immunocompromised and solid organ transplant patients) the level of protection against measles, mumps, rubella and pertussis in children with chronic diseases. vaccination coverage of recommended vaccines (diphtheria, tetanus, pertussis and vaccines against seasonal flu and pneumococci) in adults with chronic diseases (nephropathy, diabetes mellitus, COPD, heart failure, HIV and solid organ transplant patients) the level of protection against diphtheria, tetanus and pertussis in adults with chronic diseases.

Aim #1: Define and determine the prevalence of pulmonary vascular disease and diastolic dysfunction as assessed by the gold standard of invasive hemodynamic cardiopulmonary exercise testing. Aim #2: Determine the role of rest-exercise echocardiography for the assessment hemodynamics in Fontan physiology. Aim #3: Evaluate the clinical impact of pulmonary vascular disease and ventricular diastolic dysfunction.

A single site, cross-sectional, pilot study of a mHealth application. Primary Objective This purpose of this pilot study is to evaluate mHealth adherence to a developmental application, Babysparks©, by parents of infants with complex congenital cardiac disease and single ventricle heart disease. Secondary Objective(s) -To determine the demographic and infant characteristics that correlate with mHealth adherence. -The rate of developmental progress of milestones while using the application will also be compared between infants with single ventricle cardiac disease and bi-ventricular cardiac disease. Research Intervention(s)/ Investigational Agent(s) Babysparks© developmental application is the main intervention with evaluation on feasibility of the mHealth application in a pediatric cardiology population. Study participants will be parents of infants with single ventricle and bi-ventricular complex congenital heart disease who underwent cardiac surgery in the first six weeks of life and are currently less than 18 months of age. Study Population There are approximately 150 new patients a year who have undergone cardiac surgery, with an additional 150 who are 18 months of age or less. Sample Size A maximum of 400 families/year Study Duration for Individual Participants Study participants will be monitored for a minimum of 6 months with the use of the BabySparks© App; to a maximum of 24 months of use of the app or when the child reaches a developmental age of 24 months, whichever occurs first.

Management of pregnancy and risk stratification in congenital heart disease (CHD) population might be challenging especially due to physiological haemodynamic modifications that inevitably occur during pregnancy. We aim to compare the accuracy of the main published scores including CARPREG II score in prediction of maternal complications during pregnancy in CHD patients.

This study aims to evaluate the psychometric properties of a newly developed FFQ specified for northern Chinese CHD and their high risk patients (CHD-FFQ). The psychometric properties include test-retest reliability, content validity, convergent validity, discriminant validity, concurrent validity and predictive validity. Particularly, this study will measure the physiological indicators, including plasma lipid profile (i.e. TG, TC, HDL-C, LDL-C), BG, BP and BMI twice at baseline and the end. The level of these physiological indicators will be compared with the fat intake measured by the CHD-FFQ, i.e. the baseline intake to test its convergent validity. It is also expected to predict the diet-related progression of CHD risks among high-risk individuals, i.e. patients with two or more CHD risk factors as following: raised fasting blood glucose (BG) level, increased blood pressure (BP), increased triglycerides (TG), decreased HDL-Cholesterol (HDL-C), increased LDL-Cholesterol (LDL-C), smoking and central obesity (International Diabetes Federation, 2015). In addition, this study will provide the FFQ's concurrent validity in assessing the intake of energy and nutrients against the CDC-FFQ. Moreover, whether the FFQ could detect the known differences in energy intake between men and women will be established for its discriminant validity.

This is a longitudinal study that will collect demographic, anthropometric and dietary data to determine the relationships between meat and egg intake and the incidence of Type 2 Diabetes.

There is currently no routine screening for cardiac disease for pregnant women in areas of high prevalence. This study will aim to determine the point prevalence of cardiac disease in women presenting for antenatal care at Moi Teaching and Referral Hospital. More specifically, it will aim to use focused echocardiography as a screening tool to determine the prevalence of cardiac disease among pregnant women attending MTRH antenatal clinic.

The Freestyle® prosthesis (Medtronic plc, Dublin, Ireland) is a biological, porcine aortic root implanted in various combinations and techniques since the 1990s. The main indication for the choice of this prosthesis is a combined pathology with degenerated aortic valve and additional dilatation of the root often involving the ascending aorta. The Freestyle® prosthesis is also used in cases of dissection of the ascending aorta with the involvement of the aortic valve, which opens the debate on how far the ascending aorta should be replaced for a sustainable solution with calculable low periprocedural risk. Considering a lower intraoperative risk in the life-threatening situation, an extended resection of the aorta can be avoided and only the aortic root replaced with a piece of ascending aorta. On the contrary, focusing on improved long-term outcome, the technique of total arch replacement in aortic dissection was developed in emergency situations with acceptable results, which, however, were often reproducible only in large, experienced centers. Apart from the abovementioned options, the technique of proximal arch replacement can provide a tension-free anastomosis. The intention of hemiarch replacement is the attachment of the prosthesis to an aneurysm-free portion of the aortic arch helping to protect against further anastomotic aneurysms and spare the patient complex reoperation or interventional procedures in the future. As a possible drawback of the technique, especially in emergency situations, the potentially prolonged duration of surgery and the need of selective brain perfusion via axillary or carotid artery are discussed increasing the risk of stroke and further major events, which could not be reflected in current literature. However, there is still no convincing evidence of a long-term benefit in terms of re-operation and survival after hemiarch replacement. The aim of this retrospective analysis was to assess the mid-term outcome of the biological Freestyle® prosthesis in combination with operations on the ascending aorta and the aortic arch with regard to prosthetic performance, reoperations, stroke and death.

Randomized controlled trial comparing femoral vs internal jugular insertion site of central venous catheters (CVC) in newborns and infants undergoing cardiac surgery. The experimental hypothesis is that the jugular insertion site is superior to the femoral in terms of catheter colonization.

Differentiating hypertrophic cardiomyopathy (HCM) from hypertensive heart disease (HHD) unavoidably encounters diagnostic challenges especially in patient of suspected HCM with history of hypertension. Diverse and overlapping forms of HCM can often lead to ambiguity when diagnosis is based on a single genetic or morphological index. The investigators have deduced a integrated formula based on cardiac magnetic resonance (CMR) imaging and established a differentiating flow-chart between HCM and HHD, the investigators aim to identify their method in the current multi-center trial.
