Active clinical trials for "Heart Failure"

The main purpose of this study is to build a multi-center, prospective and regionally representative acute myocardial infarction(AMI) cohort，and build a study platform for heart failure caused by AMI; To explore the 1 year incidence rate of heart failure after AMI given the optimized treatment and the treatment model affecting the incidence rate of heart failure, and finally to reduce the incidence rate of heart failure by 5%.

To compare in vivo platelet and leukocyte activation and phenotype before and after Left ventricular assist device (LAVD) implantation

The study aims at assessing the usefulness of the Heartfelt1 device in patients suffering from heart failure, who have peripheral oedema. The device is non-contact and does not requires patient compliance to work. It gives an output reading of the patient's lower leg volume. During the study, this measurement will be compared to clinical standard and gold standard measurements as well as clinical grading of peripheral oedema.

This is a multi-center, non-randomized, non-interventional study to evaluate the accuracy of a remote monitoring and analytical platform for prediction of heart failure exacerbation. The platform acquires continuous multivariate vital signs from HF patients using a new ambulatory wearable (attached by an adhesive) multi-sensor device and analyzes the data using a novel machine learning algorithm.

A multicenter randomized controlled trial, with follow-up at 6 and 12 months. Physically inactive participants with chronic heart failure with preserved or mid-range ejection fraction will be randomly assigned to intervention or control arms. The six-month intervention will consist of an individualized pedometer-based walking program with weekly step goals, monthly face-to-face sessions with the physician, and monthly telephone calls with the research nurse. The intervention will be based on effective behavioral principles (goal setting, self-monitoring, personalized feedback). The primary outcome is the change in 6-minute walk distance at 6 months. Secondary outcomes include changes in serum biomarkers levels, pulmonary congestion assessed by ultrasound, average daily step count measured by accelerometry, anthropometric measures, symptoms of depression, health-related quality of life, self-efficacy, and MAGGIC Risk Score.

The objective of this study is to describe the prevalence of Multiple Hormone Deficiencies in Heart Failure with preserved Ejection Fraction.

In the United States, about 40 percent of heart failure (HF) patients are readmitted within 1-year following their first admission for HF and hospitalization accounts for approximately 70 percent of the costs of HF management. As a result, the management of HF patients is evolving from the traditional model of face-to-face follow-up visits toward a proactive real-time technological model of assisting patients with monitoring and self-management while in the community. The investigators plan to test the impact of a mobile application on clinical outcomes in HF.

To learn in a general Cardiac Resynchronization Therapy Defibrillators (CRT-D) population, which optimization techniques are used and how effective they are. It will compare 12-month response rates among different optimization methods and characterize which selected subject subgroups achieve better response than others. A subset of SMART Registry subjects will contribute to the NG4 Post Market Clinical Follow Up (PMCF) Cohort whose objective is collecting data on the NG4 CRT-D features and device usage in a real world setting and monitor long term safety associated with these devices to support CE Mark.

The aims of this project are 1) to evaluate whether circulating micraparticals (MPs) in patients with LVAD impair endothelial function and 2) to assess the procoagulative activity of circulating MPs in patients with LVAD in a prospective longitudinal study of patients undergoing LVAD implantation, 3) to analyze these parameters in the context of thromboembolic events.

Several studies have confirmed the link between chronic RV apical pacing and the development of heart failure and LV systolic dysfunction in some patients 1,2. However, questions continue to remain unanswered in regard to the adverse effects of RV pacing such as the exact amount of RV pacing that is detrimental to cardiac function and which subsets of patients are most at risk for developing cardiac dysfunction from chronic RV pacing. Rates of permanent pacemaker implantation have been increased over the last twenty years with expanding indications to include permanent pacing after AV node ablation for the treatment of drug refractory atrial fibrillation and other atrial tachy-arrhythmias. The current standard of practice is to minimize RV pacing however in patients that have had an AV node ablation right ventricular pacing cannot be avoided therefore it is important to identify if this particular group of patients is at an increased risk for developing worsening cardiac function. The purpose of this study is to compare cardiac function over time between patients that have undergone AV node ablation versus patients that have had pacemaker implantation for AV node dysfunction.
