Active clinical trials for "Heart Failure"

This is a prospective, observational study. The primary aim is to assess the diagnostic accuracy of Artificial Intelligence (AI) analysis of Point of Care (POC) handheld transthoracic echocardiogram images (POC handheld echocardiogram) compared to the current gold-standard of transthoracic echocardiogram images acquired and analysed by a British Society of Echocardiography (BSE) accredited operator, using a standard echocardiogram machine (standard TTE), for the diagnosis of Heart Failure with reduced Ejection Fraction (HFrEF), in patients referred from the community for investigation of suspected new Heart Failure (HF).

assess the relation between glycemic gab and adverse clinical outcomes in diabetic patients who hospitalized with heart failure

The purpose of this study is to determine if cachexia and changes in body composition influence pharmacokinetics of bisoprolol and ramipril and the accuracy of equations for renal function estimation.

Patients with Ischaemic and Dilated Cardiomyopathy, face an increased risk for Arrhythmic Sudden Cardiac Death. The purpose of this study is to estimate the performance of Modern Non-Invasive Indices and the performance of Programmed Ventricular Stimulation in Sudden Cardiac Death Prediction.

The purpose of CN-HF is to establish the national registration of hospitalized heart failure patients, evaluate and compare the clinical features and prognosis of diastolic and systolic heart failure, and find out the status of treatment and implementation of guidelines on heart failure in China.

The investigators hypothesize that chronic heart failure is associated with a general stem cell dysfunction, which translates into reduced paracrine function of adult stem cells from patients with chronic heart failure as compared to patients with preserved systolic function.

Aims: To test the hypothesis that Diastolic dysfunction severity correlates with adverse clinical outcome in patients with systolic heart failure.

Cardiac surgery can be not infrequently complicated by cardiac low-output syndrome due to critical preoperative conditions such as cardiogenic shock, poor left ventricular function and severe myocardial ischemia. Suboptimal myocardial protection, technical errors at graft anastomoses or of prosthesis implantation, and hibernating myocardium may further contribute to cardiac low-output syndrome occurring immediately or shortly after cardiac surgery. In this setting, veno-arterial extracorporeal oxygenation (VA-ECMO) is the only means to provide cardiopulmonary support to recovery or as bridge to transplantation. Data on the real benefit of VA-ECMO after cardiac surgery is limited and often derived from heterogeneous patient populations, which prevent conclusive results on the benefits of VA-ECMO in this setting. This issue will be investigated in the present retrospective European multicenter study. In this setting, veno-arterial extracorporeal oxygenation (VA-ECMO) is the only means to provide cardiopulmonary support to recovery or as bridge to transplantation. Data on the real benefit of VA-ECMO after cardiac surgery is limited and often derived from heterogeneous populations of patients who underwent different cardiac procedures. Patients with cardiac low-output after surgery for aortic dissection or valve surgery are expected to have different baseline characteristics (such as age and comorbidities) and underlying cardiac disease than patients undergoing isolated coronary surgery. Furthermore, available studies included patients operated two decades ago and this does not provide an exact measure of the benefits of this treatment strategy. The possible benefits of using VA-ECMO after adult cardiac surgery will be investigated in this retrospective European multicenter study.

The objective of this work is to investigate and then to sequence new biomarkers in the blood of patients with heart failure, and study their diagnostic, risk stratification and prognostic value.

The aim is to correlate relationship between congestive heart failure and onset of atrial tachyarrhythmias in pacemaker patients. Both atrial events and state of congestive heart failure are collected automatically by implanted device.
