This is a single-center, pilot study that will evaluate the effectiveness of the AHA science based CarePlans and the Ambio Health technology in improving the risk adjusted 30 day readmissions rate, patient compliance, and biometrics. The study will also be used to assess the feasibility of similar heart failure transition programs in the future.
It is well-known that muscle weakness and deconditioning play an important role in low exercise capacity of patients with HF. Interestingly, not only peripheral muscles are impaired, but also respiratory muscles. Studies have shown that patients with HF may have, in addition to decreasing maximal inspiratory muscle strength and endurance, metabolic and structural impairments in diaphragm fibers. Moreover, exercise capacity and weakness of inspiratory muscles have been associated with low quality of life and poor prognosis, which make the addition of inspiratory muscle training (IMT) reasonable in cardiovascular rehabilitation.The specifications of the loads to be imposed during IMT is the main factor determining the outcome. Studies of IMT have highlighted the need for a fixed inspiratory workload during exercise. Thus, purpose of this report was to perform a randomized clinical trial of the effects of addition of high-intensity vs. low-intensity IMT to combined aerobic and resistance Exercise in patients with heart failure.
This study will use contrast echocardiography to assess the accuracy of a new non-invasive imaging method for subharmonic aided pressure estimation (SHAPE) compared to simultaneously acquired intra-cardiac pressures measured invasively during cardiac catheterization. This study is designed to verify that contrast echocardiography using the SHAPE method, already proven in a canine model and tested in a human pilot study can be used as a surrogate for cardiac catheterization with sufficient accuracy to allow clinical applicability in humans.
The fundamental hypothesis of this project is that real-time intracardiac pressures can be monitored and quantified noninvasively in humans using a novel contrast-enhanced ultrasound technique called subharmonic-aided pressure estimation (SHAPE).This study will use contrast echocardiography to assess the accuracy of SHAPE compared to simultaneously acquired intracardiac pressures measured invasively during cardiac catheterization. This study is designed to verify that contrast echocardiography using the SHAPE method, already proven in a canine model and tested in a human pilot study can be used as a surrogate for cardiac catheterization with sufficient accuracy to allow clinical applicability in humans.
Acute heart failure is a life threatening condition requiring rapid diagnosis and treatment. However, the differentiation between heart failure and other conditions presenting with acute dyspnea is notoriously difficult in the emergency room. Point-of-care lung ultrasound is a simple, rapid and noninvasive technique directly visualizing fluid content in the lung as evidence for acute heart failure. A number of publications showed the diagnostic utility of lung ultrasound in the diagnosis of heart failure, but many open questions remain. The goal of this study is to evaluate the diagnostic accuracy of lung ultrasound to predict a cardiac origin of dyspnea in unselected patients in the emergency room as compared to standard evaluation. Further goals are to evaluate if lung ultrasound provides additional diagnostic information as compared to clinical examination, NT-proBNP and chest X-ray, to compare the diagnostic accuracy of lung ultrasound in different patient subgroups (heart failure with preserved vs reduced ejection fraction, de novo vs decompensated chronic heart failure, age ≥75 vs <75 years, women vs men and presence vs absence of concomitant pulmonary disease) and to compare demographics and clinical characteristics in different patient populations. 300 patients, aged ≥18 years presenting to the emergency room (ER) with acute dyspnoe as principal complaint will undergo initial clinical assessment of the likely etiology of dyspnea by the ER physician in charge. The second assessment by the same physician will include results of NT-proBNP according to predefined cutoffs. Final diagnosis ("Gold Standard") will be done by two experienced investigators after patient discharge taking into account the complete medical record except the results of lung ultrasound. Assessment of chest X-ray and lung ultrasound by investigators will be preforemd blinded regarding all other results.
The purpose of this study is to investigate the potential recovery of heart function in end-stage heart failure patients supported with a Left Ventricular Assist Device (LVAD) through applying a myocardial conditioning protocol. During myocardial conditioning, LVAD speed is reduced gradually in order to increase the work load of the heart. Multiple previous studies have shown that interventions like this may improve heart function and give patients the opportunity for a better quality of life.
The EasySense device is a non-invasive device designed to measure lung fluid in patients with Congestive Heart Failure (CHF). This study seeks to evaluate the efficacy of the EasySense system in measuring lung fluid volume.
The ADAPTION trial is an investigator initiated prospective randomized doubleblind cross-over pilot study in a multi-center setting. Aim: to assess the ability of minute ventilation (MV) sensor driven rate adaptive atrial stimulation to restore functional capacity and quality of life in heart failure patients with chronotropic incompetence. Methods: heart failure patients (left ventricular ejection fraction ≤35% & New York Heart Assessment II or III) who were implanted with a 2-chamber implantable cardioverter defibrillator (ICD) device equipped with a MV sensor that are diagnosed with chronotropic incompetence will be included in the study. Patients will be randomized in a 1:1 fashion to rate responsive pacing (MV sensor only) function ON (AAIR mode) or OFF (DDI mode). After 3 months the pacing mode will be switched to the opposite mode.
Little is known about the hyperemic efficacy of IV adenosine as well as safety in patients with heart failure with reduced ejection fraction (HFrEF) because they were excluded from the major FFR studies. We will evaluate the feasibility and hyperemic efficacy of IV adenosine in patients with HFrEF in comparison with IC nicorandil for invasive physiological assessment using a coronary pressure wire.
The study aims to explore the effectiveness of psycho-behavioral intervention on depressive symptoms among older adults with chronic heart failure. Meanwhile, the effect on cardiac function and quality of life will also be explored.
