Active clinical trials for "Heart Valve Diseases"

By bioelectrical impedance spectroscopy (BIS) association of fluid status in patients with valvular heart disease and cardiovascular outcome will be assessed.

Chronic Heart Failure Analysis and Registry in the Tohoku District 2 (CHART-2 Study) is a large, prospective, hospital-based cohort study to investigate the following: Characteristics of patients with chronic heart failure and prognostic risks of these patients. Characteristics of patients with high risk for heart failure and critical factors which predict the development of symptomatic heart failure in these patients. The incidence and prognostic impact of metabolic syndrome in patients with chronic heart failure. The association between metabolic syndrome and the development of symptomatic heart failure.

Background: Treatments for structural heart and valve disease are quickly changing. But treatment could be improved. Researchers want to gather data from people with this disease. They want to find problems and seek new ways to make treatments better. Objective: To find people with structural heart and valve disease with common features to study. To find flaws and patterns in procedures related to this disease. To share findings with other researchers. Eligibility: People ages 18 and older who are receiving care from the structural heart and valve program at the participating NHLBI structural heart disease network sites that are part of the study Design: Participants will be screened with their consent. This will occur when they give their standard consent for medical care. Participants will have their data collected in the course of standard medical care. Data include: Demographic data Protected health data Personally identifiable data Medical records Medical images. These could include X-rays, CT scans, and MRI scans. The study could find something that would impact participants care. If this is the case, their doctors will be told. Participants data may be shared with other researchers. ...

Avicena is developing new non-invasive methods (hardware and software) for diagnosis of a variety of heart conditions. This study is designed to compare data obtained using Avicena's device, the Vivio, to data obtained from transthoracic echocardiography (TTE) for the diagnosis of moderate-to-severe aortic stenosis. Aortic stenosis (AS) is a disease of the valve (aortic valve) that separates the left ventricle of the heart from the aorta. When AS is severe, the heart cannot pump adequate amounts of blood into the arterial tree. AS is often silent until the disease is severe. This study compares a rapid test using Vivio to a longer and more expensive test that is the current gold standard for diagnosis of AS, TTE.

The purpose of this study is to assess exercise patterns during home-based or center-based cardiac rehabilitation participation.

In-hospital mortality after cardiac surgery ranges from 2-6%. Many patients suffer from major adverse cardiovascular events (MACE) which results in impaired disability-free survival. Troponin plays the central role in identifying MACE. However, interpretation after cardiac surgery is difficult due to ischemia-reperfusion-injury and direct surgical trauma. While the 4th universal definition of type 5 myocardial infarction uses the 10 x ULN as cut-off, >90% of patients after on-pump procedures exceed this cut-off. Clinical consequences are unclear. The dynamic of Copeptin and Heart-type fatty acid binding protein (H-FABP) concentrations starts very early, i.e. several hours before Troponin. The investigators plan a prospective multicenter cohort study to evaluate 1) the independent association between Copeptin and H-FABP with disability -free survival and MACE after cardiac surgery; 2) the predictive gain of their addition to the Euroscore II; 3) the independent association between H-FABP and acute kidney injury.

Valvular heart diseases (VHD) are the most common causes of mortality and morbidity after coronary artery disease, hypertension, and heart failure, especially in senile patients who have more comorbidities and often require intervention. The prevalence of senile VHD is increased gradually as the growth of the age. In addition important changes have occurred as regards the presentation and treatment of the disease over recent years. However, there is little information about senile VHD in China. The purposes of this study are to evaluate the clinical characteristics, reasons for hospitalization, risk stratification, treatment modalities, quality of life and outcomes of senile hospitalized patients with VHD, to determine the risk factors affecting the prognosis, further to lay the foundation for establishing a prognosis model suitable for Chinese senile VHD.

This study investigates the association between level of suPAR and valvular heart disease in patients who have severe aortic stenosis or severe aortic regurgitation using commercially available suPARnostic standard enzyme-linked immunosorbent assay (ViroGates, Denmark)

This longitudinal cohort study evaluates the relationship of myocardial tissue markers characteristics assessed by cardiac MRI, with clinical measures of symptoms and functions in adults with primary mitral regurgitation. Participants are followed conservatively or may choose to undergo surgical repair at the discretion of their clinical team.
