Filter by:The purpose of this registry study is to collect information about routine clinical practices with device implantation to treat bradycardia and cardiac systolic dysfunction (heart rhythm disorders) across global centers of excellence in cardiac pacing. In particular, this study will examine the use of conduction system pacing (CSP) in clinical practice. Information collected in the registry will help researchers better characterize strengths and limitations of current technology and treatments.
There is existing data in the literature that suggests an additional predictive value of three dimensional ECG with respect to the presence of electrical abnormalities and for an existing cardiac disease. Especially regarding patients who suffered from a myocardial infarction in the past (post MI patients), evidence has been provided for a potential association of 3D repolarisation abnormalities and incidence of sudden cardiac death (SCD). In addition, there is some vague evidence of so called 3D ECG and prediction of coronary artery disease. This 3D ECG device is using the technology of 3D ECG vector loops and is assessing the variability of these ECG vector loops in the 3-dimensional space. Based on these data, the parameters of 3D ECG are suggested to carry certain value to predict or to identify individuals already suffering from a cardiac disease or being at risk experiencing a cardiac event in the future. In this context we performed a preliminary study with 3D-ECG device in healthy volunteers evaluating the robustness of this method with respect to reproducibility, intra- and intra-observer variability which could be confirmed. We thus postulate that the 3D ECG technology might bear the potential to serve as a sufficient screening method for diagnosing cardiomyopathy in patients with an unknown heart failure etiology.
The focus of this study is to test the efficacy of a 12-week, phone-delivered Positive Psychology-Motivational Interviewing (PP-MI) intervention, with additional twice weekly PP and health behavior text messages for a total of 24 weeks (with interactive, algorithm-driven, goal-focused text messages in the final 12 weeks), compared to an attention-matched MI-based educational condition, in a randomized trial (NIH Stage II) of 280 patients with New York Heart Association class I-III Heart Failure (HF).
Heart Failure research registry is a collection of computerized information about individuals with heart failure. The database in this registry is obtained from several Jordanian medical centers which will represent an extremely valuable resource for epidemiological research on heart failure patients.
In this project, Institute of Bioengineering & Bioimaging (IBB), A*STAR would like to collaborate with Massachusetts General Hospital to aggregate patient data and to further develop its software algorithm using machine learning and statistical models for predicting exacerbations and deterioration on 60 patients with cardiopulmonary diseases.
The correlation of coronary microvascular function and body composition with cardiopulmonary exercise capacity will be assessed in patients with heart failure with preserved ejection fraction.
Patients with heart failure (HF) represent a large population of patients who are at high risk for complications related to undiagnosed atrial fibrillation (AF). However, currently there are limited modalities for early AF detection and subsequent stroke prevention in this high-risk population. An implantable cardiac monitor (ICM) is inserted subcutaneously and can provide long term arrhythmia information via remote monitoring. The ASSERT-AF study seeks to accurately define the burden of AF and other arrhythmias in high-risk HF patients using an ASSERT ICM.
Vasoplegia is a common complication after heart surgery for heart failure. With vasoplegia, the blood vessels can no longer squeeze properly, causing low blood pressure that is sometimes difficult to treat with medication. One of the causes of this complication is likely to be the use of the heart-lung machine, a device that takes over the function of the heart and lungs during surgery. The blood then comes into contact with a foreign environment and this can cause a reaction of the immune system. Patients with heart failure are extra sensitive to this reaction. CytoSorb device is a filter that can be built into the heart-lung machine and can reduce the response of the immune system. Therefore, this study aims to investigate whether the use of this filter during heart surgery in patients with heart failure results in a less frequent occurrence of vasoplegia after surgery.
It was aimed to examine whether the arm endurance exercise training is effective in addition to the lower cycling training program in order to alleviate the negative functional results in heart failure patients with ICD.
Heart failure (HF) is a chronic disease with weakened heart muscles or abnormal pressure within the heart chambers result in breathlessness, leg edema, or fatigue. A subclass of HF shows reduced heart muscle contractility, which is represented by the left ventricular ejection fraction (LVEF). Valsartan is an angiotensin II receptor blocker, a major drug class for heart failure. Sacubitril/valsartan is a combination of 2 drugs, classified as a new class of drug called angiotensin receptor neprilysin inhibitor (ARNI). Although these medications are both first-line treatment in HF with reduced LVEF, recent guidelines encourage the use of sacubitril/valsartan in patients with ongoing symptoms. After successful treatment, some patients experience recovery of LVEF. In these patients, otherwise called heart failure with improved ejection fraction (HFiEF), it is not clear whether continued treatment with sacubitril/valsartan or valsartan is beneficial in terms of relapse of heart failure or worsening of LVEF. Therefore, the investigators aim to determine whether the treatment with sacubitril/valsartan versus valsartan differs in clinical outcomes after 1 year in HFiEF patients by observing the change in blood test markers of heart failure (N-terminal prohormone of brain natriuretic peptide; NT-proBNP) and aggravation of HF defined as reduced LVEF, congestive symptoms, hospitalization or death from HF.
