Active clinical trials for "Heart Valve Diseases"

The purpose of this study is to evaluate the clinical efficacy of the mid-term treatment with sildenafil in patients with persistent moderate or severe pulmonary hypertension (PH) after a heart valve intervention.

The purpose of this study is to clarify the changes of neurocognitive function of patients undergoing cardiac valve disease before and after surgical treatment under cardiopulmonary bypass operation, and to predict the neurological prognosis of such patients through combined imaging technology, so as to improve and avoid the occurrence of postoperative neurological dysfunction in such patients.

The etiology and specific pathogenesis of many cardiovascular diseases such as coronary atherosclerosis, cardiomyopathy, atrial fibrillation, and stroke are still unclear. Improving diagnosis and treatment, clarifying the pathogenesis, and providing scientific basis for the prevention and treatment are hot research topics in the study of cardiovascular and cerebrovascular diseases. This study intends to collect clinical data and biological specimen data of patients with cardiovascular and cerebrovascular diseases who meet the inclusion and exclusion criteria, and use multi-omics technology to deeply understand the pathogenic mechanisms of cardiovascular and cerebrovascular diseases and provide new ideas for specific and individualized treatment of patients with cardiovascular and cerebrovascular diseases, to construct early predictive prognostic models and provide a basis for effective treatment of clinical practice in patients with cardiovascular and cerebrovascular diseases.

Patients that have cardiac surgery may suffer from unrecognized cerebral ischemia or loss of blood flow to the brain temporarily during surgery. This temporary loss of blood flow to the brain may result in a condition called delirium. Delirium is a type temporary confusion. There are some strategies that can help reduce cerebral ischemia during cardiac surgery which can help lead to a reduction in the incidence of delirium. The investigator believes that a strategy called remote ischemic preconditioning will help to reduce the incidence of delirium incidence after cardiac surgery. Remote ischemic preconditioning is a brief exposure to ischemia. This brief exposure to ischemia occurs in an area of the body that is not undergoing a procedure. This brief exposure to ischemia is not long enough to cause any damage to the body and it has been demonstrated to help protect against more severe ischemic injury that may occur later during surgery. In this study the investigator will use remote ischemic preconditioning to see if it can reduce the incidence delirium after cardiac surgery.

The aim of this study is to prove that using a CytoSorb(TM) filter in the cardiopulmonary circuit attenuates the inflammatory response to extracorporeal circulation in patients undergoing cardiac surgery. The hypothesis is that removing cytokines from patients' blood by the CytoSorb device significantly improves circulation and outcome in patients undergoing on-pump cardiac surgery.

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.

Bicuspid Aortic Valve (BAV) is the most common congenital heart disease affecting 1-2% of the population. The aortic dilation and aortic valve degeneration are common complications in patients with BAV. Statins have shown a reduction in the expression of metalloproteinases of the extracellular matrix observed in aortic aneurisms. Several retrospective studies have suggested the benefit of the statins to reduce aortic dilation in patients with BAV. Moreover, although statins did not show to be useful in the progression of aortic stenosis, different studies have suggested a higher profit when the valve affection is not severe. The objective of this study is to determine whether atorvastatin is effective at reducing the progression of aortic dilation in patients with BAV.

The study aims to identify the Following: - incidence and mortality of cardiac Surgery associated -AKI based on the new consensus diagnostic systems of KDIGO (Kidney Disease Improving Global Outcomes). use of biomarkers for the early detection of clinical and subclinical cardiac Surgery associated-AKI. risk factors and prediction models of cardiac Surgery associated-AKI. optimal cardiac surgical procedures including conventional versus minimally invasive approaches, on-pump versus off-pump, and optimal management of cardiac surgical support including duration of CPB, perfusion pressure, hemodilution, and hypothermia during CPB. controversial pharmacologic therapies for the prevention and treatment of cardiac Surgery associated-AKI including statins, sodium bicarbonate, and N-acetylcysteine (NAC).

Heart problems are amongst the most common physical illnesses in children and young people (CYP). They can be present from birth or develop as CYP get older and are linked to increased physical and psychological difficulties overprotection from caregivers and healthcare providers and reduced quality of life. While adults are offered exercise classes and lifestyle advice after a heart problem, CYP with heart problems are not. Improving health behaviours in people with heart problems is vital, improves quality of life and reduces additional illnesses (i.e obesity, diabetes). Approximately 1 in 3 CYP with heart problems have anxiety and/or depression so it is also important to support their mental health. One way to do this is to develop and test the acceptability and feasibility of a trial of cardiac rehabilitation (CR) consisting of exercise with mental health support for CYP. The aim is to develop and test the feasibility and acceptability of a trial of a cardiac rehabilitation programme for CYP.

The aim of this clinical trial is to assess the effect of early bedside cycling exercises post heart valve surgeries. the main question aims to answer: whether adding an early bedside cycling exercise will have an effect on patient's functional capacity, other physical outcomes and have an effect on patient's psychological state? The participant will be assessed blindly the physical and psychological outcomes before getting randomly allocated in groups. the bedside cycling will be introduced and conducted in the intervention group in addition to the conventional physical therapy cardiac rehabilitation routine through preexisted physical therapy staff who present the hospital: The routine use of breathing exercises, coughing techniques, chest wall vibrations, and mobilization is common during the first postoperative days. On the other hand, the control group will only receive the conventional rehabilitation, subsequently, both groups will be assessed and compared by addressing the difference of the outcomes before discharging from the hospital.
