Active clinical trials for "Heart Failure"

Heart failure with preserved ejection fraction (HFpEF) is a common and growing condition with a poor prognosis but the pathophysiology and management are still being investigated. The PREFER-CMR project aims to evaluate and validate the application of novel 4D cardiac magnetic resonance flow dynamic methods to measure left ventricular pressures and validate these measurements with direct pressure measurement by coronary angiography. This is a prospective observational study of patients with HFpEF undergoing clinical evaluation with coronary angiography who will also undergo contemporaneous cardiac MRI. The primary outcome will be the level of agreement between the two methods using angiography as the reference method.

Patients presenting to the Emergency Department with shortness of breath and (suspected) heart failure will be screened and randomized to either a standard of care or a procalcitonin-guided arm. Procalcitonin-guided arm: a procalcitonin level (cutoff 0.2 ng/ml) will be used to support decision on antibiotic therapy initiation. Standard of care arm: the decision on antibiotic therapy will be based on the physicians intent to treat. The patients will be followed up 30 and 90 days after randomization to evaluate the survival status, re-hospitalizations and further antibiotic therapies.

The purpose of this study is to determine whether a modification of the diet of malnourished patients admitted for heart failure is beneficial in term of mortality,hospitalizations and quality of life.

The main purpose of this study is to validate an intensive protocol of insulin infusion and subsequent subcutaneous insulin administration with the support of continuous glucose monitoring, in addition to reference finger-stick values.

A proprietary machine-learning algorithm has been developed to model continuous pulmonary artery pressure (PAP), a physiologic marker of cardiopulmonary function. The algorithm was developed from PAP recordings obtained during invasive right heart catheterization. The study will evaluate whether this algorithm can perform as well when embedded into a non-invasive wearable device that records EKG, heart sounds, and thoracic impedance has yet to be established.

The specific objectives and methods of this project are: (1) To test the feasibility and accuracy of integrating EEG, MECG and EMG for detecting the severity of diseases such as aortic stenosis, heart failure and ischemic stroke. (2) Improve the accuracy of this multi-channel brain-heart-muscle device by using an artificial intelligence auxiliary system. (3) Provide tailor-made interdisciplinary treatment strategies for patients with different disease states.

The goal of this cross-sectional study is to investigate the prevalence of sarcopenia in patients with Heart Failure. The main question it aims to answer is: Whether there is a difference in the prevalence of sarcopenia across the spectrum of HFpEF (Heart failure with preserved ejection fraction) and HFrEF (heart failure with reduced ejection fraction). This is an observational study. The participant population involves patients with heart failure with preserved ejection fraction and heart failure with reduced ejection fraction. Healthy volunteers will be recruited as controls in addition to adults with asymptomatic Type 2 Diabetes. Participants will undergo the following: Skeletal muscle mass, quality and body composition assessments using magnetic resonance imaging (MRI) and bioelectrical impedance analysis (BIA) Skeletal muscle strength assessments (Dynamometer, FysioMeter, handgrip strength) Skeletal muscle energetics assessment (31p-Spectroscopy pre/post-exercise recovery) Researchers will compare Heart failure groups with healthy controls and adults with asymptomatic type 2 Diabetes to see if there are significant differences in the strength, mass and quality of skeletal muscle.

To find out if the time delays between the first medical contacts till the device has an impact on LV functions estimated by transthoracic Echocardiography and if it's correlated to heart failure incidence in non-diabetic patients with STEMI treated with primary PCI

The CHANNELED-Registry is a multicenter retrospective study to (1) systematically assess the mechanism and origin of ventricular tachycardia in patients with end-stage heart failure carrying an left ventricular assist device (LVAD) and (2) to evaluate procedural parameters and outcome of ventricular tachycardia ablation in this special subset of patients.

The proposed project is a 2x2 factorial designed study aimed at assessing the impact of 1) a home tele-monitoring system and 2) a flexible diuretic regimen among high risk heart failure patients in the University of Michigan Health System (UMHS).
