Active clinical trials for "Heart Diseases"

A prospective, longitudinal, non-comparator, non-randomized observational cohort study to assess the quality of life in adult patients affected by hypertrophic cardiomyopathy and thoracic aortic dilatations who are not amenable to surgery, as well as those affected radiation-induced cardiac disease caused by radiation therapy.

The goal of this clinical trial is to validate performance claims for method comparison for ABL90 FLEX PLUS in heparinized neonatal arterial, venous, and capillary whole blood for ctBil and FHbF in a Point of Care (POC) setting.

After basic clinical screening including history and physical, Point of care ultrasound will be performed to look at Mitral, Aortic and Tricuspid Valves for regurgitation or stenosis. For patients with confirmed Rheumatic heart disease (RHD), treatment and referral depending on stage of disease. Antibiotic prescription could be shifted to community health workers delivering preventive medications via practical clinical algorithms, diagnostic tools, availability of appropriate antibiotics, and supportive supervision. Patients will have repeat imaging at 2 years and 5 years to look at the outcome of delayed progression of valve disease.

In this clinical study the investigators will evaluate if it is feasible to pre-operatively identify low-risk patients, and to identify patients with cardiac pathologies with the LynxPatch.

Long-standing hypertension may cause an impairment in microvascular coronary circulation which is involved in many different cardiac conditions. Renal denervation (RDN) has been successfully proven as a valuable and powerful therapeutic choice to consider for patients with resistant hypertension; moreover this procedure looks promising in other cardiac disease such as heart failure and atrial fibrillation, given its ability to downregulate sympathetic nervous system The aim of this study is to explore the effect of renal denervation and blood pressure control on coronary microvascular dysfunction. This is a multicenter, prospective, non randomized, open-label, interventional study. Consecutive patients with resistant hypertension, non obstructive coronary artery disease and documented microvascular dysfunction will be enrolled. Patients will undergo renal denervation by Spyral Symplicity 3 and re-assessment of coronary microvascular function 12 months after the procedure. Primary endpoint will be the difference in average index of microcirculatory resistance value.

Left bundle branch block (LBBB) exists in about 25% of patients with congestive heart failure and is associated with worsened prognosis. Cardiac resynchronization therapy (CRT) has been one of the most important advancements in the past two decades for patients with LBBB heart failure. However, 30-40% of patients receiving a CRT do not benefit from it. In this study, the investigators will test a noninvasive device to evaluate acute effect of CRT during implantation and at follow-up CRT controls. In addition, echocardiography will be performed during CRT turned ON and OFF to visualize the changes in intraventricular flow and functional parameters of the heart.

Stress is highly prevalent in patients with ischemic heart disease (IHD) and is associated with lower health-related quality of life and worsened cardiovascular outcome. The importance of stress management is now recognized in recent cardiovascular guidelines. However, effective stress management intervention are not implemented in clinical routine yet. The development of easily disseminated eHealth interventions, particularly mHealth, may offer a cost-effective and scalable solution to this problem. The aim of the proposed trial is to assess the efficiency and cost-effectiveness of the mHealth intervention 'mindfulHeart' in terms of reducing stress in patients with IHD.

Moderate sedation is used in the catheterization laboratory relieve the anxiety and discomfort associated with access and other aspects of the procedure. Whether being in a fasting state (nothing per os, NPO) at the time of the procedure is beneficial or harmful is not well known, but patients are typically required to be fasting at the time of elective procedures, guidance derived from procedures that require general anesthesia. Whereas the typical thinking was that fasting prior to procedures would minimize the risk of aspiration in the event of intubation, or nausea and other symptoms generally, several studies have shown that prolonged fasting prior to procedures is associated with increased nausea, vomiting, aspiration and procedure recovery time. We aim to evaluate patient satisfaction, nausea and immediate outcomes of patients who are not kept NPO prior to cardiac catheterization.

Greater diagnostic accuracy is required to find out who is at risk of a heart attack as this can reduce the requirement of more invasive downstream tests and thereby improve the patient experience and also reduce their exposure to risk. Stress echocardiography is a routine clinical test that involves using ultrasound to image the heart whilst it is under stress to assess the risk of a heart attack. This study will focus on developing more accurate analysis tools to interpret the results of these stress echocardiographic scans. New methods will be tested to measure the function of each part of the heart muscle, using advanced analysis of the information obtained when high-frequency sound waves are bounced off the heart inside the chest. The researchers will measure and report exact heart function during stress, so that they will be able to recognise normal hearts and those with any disease. New computer methods will be developed to display any abnormality, which will make it easier for doctors to choose the best treatment for patients who are at risk. The goals and potential benefits of this research proposal are to update the interpretation of a routinely used clinical test (stress echocardiography) to produce a reliable new method for diagnosing the precise effects of diseased arteries on the function of the heart muscle; to develop new computer graphics that adapt to show individual risks for each patient; and to implement new computer models that can be constantly updated

The objective of this study is to establish AI algorithm based on the deep learning to strengthen the ability to classify the heart murmurs of healthy people and different major or other subdivided congenital heart diseases(CHDs) and to evaluate the effectiveness of artificial intelligence technology-assisted heart sound recognition system (referred to as: Heart sound AI recognition system) for multi-center CHD screening.
