Optimising a Digital Diagnostic Pathway for Heart Failure in the Community
Heart FailureThis 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).

Arrhythmia Prediction Trial
Myocardial InfarctionDilated Cardiomyopathy1 morePatients 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.
China National Heart Failure Registry

Chronic Heart FailureCachexiaThe 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.
Paracrine Mechanisms of Bone Marrow Stem Cell Signalling in Chronic Heart Failure
Heart FailureThe 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.

Comparison of Non-invasive to Invasive Assessment of Jugular Venous Pressure
Heart FailureCongestionAssessment of the jugular venous pressure (JVP) is an important clinical sign and correlates with right atrial (RA) pressure. A patient with heart failure (HF) typically has an elevated JVP, but in cases of dehydration JVP may be low. Assessment of the JVP is key to the management of patients with fluid overload or needing diuretics. Currently the assessment of JVP is made by the physician by direct visualization of the neck veins. However this is inaccurate, may vary between investigators and depends largely on the patient's habitus. The JVP and RA pressures may also be directly measured by catheterization (a routine during right heart catheterization), but this is an invasive procedure that is seldom performed. A thermal movie of the external jugular vein at a specific neck position may help to measure the JVP. In this study different modalities of JVP assessment (clinical assessment, thermal image and invasive measurement) are to be compared Patients scheduled for right heart catheterization at the Shaare Zedek Medical Center for non-study related medical indications will be approached. Non-invasive estimates of JVP will be performed independently prior to the right heart catheterization, during the waiting period (within 2 hours) prior to catheterization. These will include up to 2min of thermal camera recording (to be analysed offline) and a physician's JVP evaluation. The angle of the patient's upper body will be 30-60°, the rotation of the neck will be optimal for filming, and the neck area may be cooled to enhance the images. Blinding to the results will be confirmed by performance with separate investigators and separate data registration. Right heart catheterization will then be performed and RA pressure will be recorded, as well as pulmonary and wedge pressures. JVP measured by physician and thermal image will be matched with invasive catheterization (the gold standard) using Bland Altman plots and Spearmann correlation and comparison between methods will be performed.
