NCT ID: NCT03705650 Recruiting - Cardiac Disease Clinical Trials


Start date: October 10, 2018
Phase: N/A
Study type: Interventional

Establish transthoracic echocardiogram (TTE) exams performed with Bay Labs EchoGPS guidance technology can be used in a primary care setting to accurately identify cardiac disease. In Phase I TTE exams with EchoGPS will be compared to findings from a commercially available, FDA 510(k)-cleared reference device (Terason uSmart 3200t, point-of-care ultrasound) without EchoGPS assistance technology. Study is non-significant risk (NSR).

NCT ID: NCT03704701 Not yet recruiting - Clinical trials for Cardiovascular Diseases

The Interrogation of the Cardiomyopathy of Chronic Kidney Disease With advancEd caRdiac Imaging

Start date: October 2018
Study type: Observational

Patients with kidney failure have a much higher risk of heart disease compared to people of the same age without kidney failure. The reason for this is not fully understood. In this project we will use Cardiac MRI (CMR), which is a very detailed scan of the heart and blood vessels, to try to better understand the cardiovascular changes that occur in kidney failure. We will perform CMR scans in 30 patients before and after dialysis (a treatment for patients with kidney failure) to see whether dialysis changes the heart muscle. The same patients will also undergo another type of heart scan, called a CT scan. This will allow us to compare the pictures from the 2 different types of scan to help us better understand any damage to the heart muscle that is present. Finally, we will test a new way to measure hardening of blood vessels on CMR. These three studies will help us to better understand the heart and blood vessel changes that happen in kidney failure. This research will also be useful for patients without kidney failure. We hope to be able to use it in the future to see which new treatments might be able to reduce the risk of heart disease in patients with kidney failure.

NCT ID: NCT03700645 Not yet recruiting - Diabetes Mellitus Clinical Trials

Allopurinol in Diabetes Mellitus and Multivessel Coronary Artery Disease

Start date: October 1, 2018
Phase: Phase 4
Study type: Interventional

Atherosclerosis is a progressive disease of the arterial wall, arising from the combination of endothelial dysfunction and inflammation. This link is exacerbated in diabetic patients. Uric acid is known to generate oxidative stress and it's elevated levels has been shown to be associated with cardiac hypertrophy, inflammation, myocardial fibrosis and diastolic dysfunction. Allopurinol inhibits xanthine oxidase, an enzyme that regulates uric acid production. In observational studies it has been shown to reduce ischemia, inflammation and improve coronary flow. The aim of this study is to see whether treatment with Allopurinol in patients diagnosed with multivessel disease and undergoing treatment with either percutaneous coronary intervention (PCI) or coronary artery bypass surgery (CABG) , will reduce markers of inflammation and improve quality of life and major adverse cardiovascular effects (MACE).

NCT ID: NCT03696446 Not yet recruiting - Clinical trials for Coronary Heart Disease

E-health Intervention for Cardiac Rehabilitation

Start date: October 15, 2018
Phase: N/A
Study type: Interventional

Cardiac rehabilitation (CR) is designed to increase healthy behaviours (e.g. physical activity, healthy eating, smoking abstinence) and reduce risk factors (e.g. high blood pressure & cholesterol) in order to improve quality of life and health among people with heart disease. Unfortunately, few patients attend CR, often reporting several barriers to access including travel distance, parking fees and lack of time. Advances in technology have the potential to improve accessibility and delivery of CR programs, and improve patient empowerment. The University of Ottawa Heart Institute has developed an e-health program called the Virtual Cardiac Rehabilitation Program (VCRP); an online cardiovascular health management system (website & Smartphone app) that provides strategies for the control and management of risk factors. The goals of VCRP are to: empower and educate patients; foster better communication between patients and their health care team; stimulate shared decision making; and, facilitate care coordination leading to better health outcomes. The VCRP provides patients with: real-time access to their health information, as well as tracking of risk behaviours and factors through integration with devices; a wellness plan; access to a personal on-line health coach; goal-setting notifications; on-line community forums; and, circle of care access to information. The aim of this project is to evaluate the effects of VCRP (with integrated fitness tracker) compared to a standard, home-based CR program. The study will look at changes in: patient empowerment; health behaviours; risk factors; quality of life; clinical outcomes; and, costs. The study will improve our understanding of: patient and provider needs; program usability; and shared decision-making. Results will inform the use of e-health programs such as VCRP into healthcare settings to improve patient empowerment, shared decision-making, and the ability to integrate wearable monitors to improve health behaviours.

NCT ID: NCT03690518 Recruiting - Clinical trials for Heart Defects, Congenital

Rehabilitation of Adolescents and Young Adults With Congenital Heart Diseases

Start date: July 27, 2018
Phase: N/A
Study type: Interventional

The investigators aim to measure the impact of a rehabilitation program in congenital cardiology in terms of health related quality of life. The orginality of the rehabilitation program consists in its design : initial hospitalizationfor a short period of time (5 days) at the rehabilitation center, followed by 11 weeks of rehabilitation at home under the supervision of a specialized sports trainer.

NCT ID: NCT03690245 Not yet recruiting - Clinical trials for Hypoplastic Left Heart Syndrome

Initiation of Resuscitation While Attached to the Cord With Congenital Heart Disease

Start date: November 1, 2018
Phase: N/A
Study type: Interventional

Before birth, the placenta (a structure with many blood vessels attached to the inside of your womb) and the umbilical cord (the umbilical cord is attached to the placenta) are sending oxygen and nutrients from the mother's blood through the umbilical cord to the baby. After a baby is born the cord is clamped and babies have to start breathing and support themselves. At the moment when a baby with congenital heart disease is born they will have their cord clamped immediately (this is called immediate cord clamping (ICC)). After ICC the clinical team will start to help a baby transition by carefully monitoring their oxygen saturation (give oxygen if needed), provide warmth, and dry and stimulate. Several animal studies have shown that clamping the cord right after birth might causes the baby to miss the benefits of receiving blood from the umbilical cord / placenta. Delayed Cord Clamping (DCC) is when the baby stays attached to the cord for a longer time. Studies show that DCC has many benefits especially for a newborn baby, such as higher iron storage, less need for blood transfusions, and improved circulation. This can be done while the baby is breathing on its own or while we help you baby breath (this is called resuscitation). This study aims to examine whether DCC while providing resuscitation in infants with CHD is helpful compared to immediate cord clamping. Prior to the birth of your baby, a sealed envelope will be opened and your baby will be randomly assigned to either the DCC with resuscitation group or the ICC group. 40 babies will be enrolled into this study, 20 in each group. In the DCC group, the umbilical cord will be clamped after 120 seconds during which time your baby will receive the care he/she requires by the NICU team. In the ICC group, the umbilical cord will be clamped immediately and he/she will be brought over the resuscitation bed to be cared for by the same team.

NCT ID: NCT03688815 Completed - Clinical trials for Ischemic Heart Disease

NCT ID: NCT03687008 Not yet recruiting - Clinical trials for Single Ventricle Heart Disease

Cognitive Intervention to Improve Working Memory

Start date: July 1, 2019
Phase: N/A
Study type: Interventional

Adolescents with single ventricle heart disease (SVHD) (10 males and 10 females) with mild to moderate cognitive impairment will participate in a total of 25 computer-based working memory training sessions, each 30-40 minutes (5 days a week for 5 weeks) supervised by a trained coach. Primary objective is to evaluate the impact of the Cogmed intervention on working memory scores and the secondary objective to assess brain tissue changes with magnetic resonance imaging (MRI) using diffusion tensor imaging (DTI) techniques, measures of mean diffusivity pre- and post-intervention.

Cardiac Biomarkers in Patients With Single Ventricle Physiology

Start date: March 1, 2018
Study type: Observational

All neonates with congenital heart disease undergoing stage one palliation (Norwood procedure, Damus-Kaye-Stansel procedure) at Texas Children's Hospital will be regularly monitored for B-type natriuretic peptide (BNP) and Troponin level before the surgical procedure, on arrival to the cardiac intensive care unit after their surgical procedure, every 6 hours during the first 24 hours of the post-operative period, followed by daily levels for the first week, and then weekly during patient's regular laboratory work up schedule. These cardiac biomarkers are linked to demographic, hemodynamic, respiratory, pharmacological data available via Sickbay.

NCT ID: NCT03677232 Completed - Quality of Life Clinical Trials

The Living Experience of Hong Kong Chinese Adolescents With CHD.

Start date: August 11, 2017
Study type: Observational [Patient Registry]

This study aims to explore the impacts of CHD and its limitations on adolescents and the living experience of adolescents living with CHD. Hong Kong Chinese adolescents with CHD are having reduced psychological well-being and quality of life than their healthy counterparts. Qualitative study is therefore needed to explore how CHD may impact on the adolescents' psychological well-being and quality of life.
