Laparoscopic Sleeve Gastrectomy as Bridge-to-Candidacy for Obese Left-Ventricular Assist Device...
Heart FailureObesityIn LVAD (Left-Ventricular Assist Device) patients, evidence is lacking regarding the safety and efficacy of Laparoscopic Sleeve Gastrectomy (LSG) as a means to reach a Body Mass Index (BMI) within listing criteria for heart transplantation. To our knowledge, this is the first prospective study to evaluate laparoscopic sleeve gastrectomy in LVAD patients as bridge-to-candidacy for heart transplantation.
Safety of HMA-CD20 in Patients With HFrEF
Heart Failure With Reduced Ejection FractionThe study is a phase II single-centered, single group, prospective clinical trial to evaluate the safety of HMA-CD20 doses among stable patients with class III/IV according to the NYHA classification with HFrEF receiving standard of care therapy. The index qualifying HFrEF must have EF < 40% based on echocardiographic or cardiac MRI techniques, heart failure class III/IV according to the NYHA classification,aged 40-60 years, being diagnosed less than 12 months before enrollment of study, following the standard heart failure treatment regimen.
the Effects of YangXinShi (YXS) on the Quality of Life and Exercise Tolerance in Patients With Chronic...
Chronic Heart FailureThe investigators set out to evaluate the effects of the traditional Chinese medicinal mixture under the brand name YangXinShi (YXS) on the prognosis in patients with chronic heart failure when it is combined with the optimal combination drug treatment of heart failure.
The Effects of Inspiratory Muscle Training in Patients With Heart Failure and Obstructive Sleep...
Chronic Heart FailureThis research aims to evaluate the effects of inspiratory muscle training (IMT) on apnea hypopnea index, sleepiness, sleep quality, cognitive function, motor task, executive function, quality of life, chemoreflex sensitivity and vagal modulation of heart rate in patients with heart failure and obstructive sleep apnea syndrome.
Beta3 Agonist Treatment in Chronic Pulmonary Hypertension Secondary to Heart Failure
Pulmonary HypertensionMirabegron2 moreThe purpose of this study is to evaluate the efficacy and safety of mirabegron (a B3 adrenergic receptor agonist) in patients with pulmonary hypertension secondary to heart failure by conducting a randomized multicenter phase II placebo-controlled clinical trial.
Ubiquinol Treatment in Patients With Heart Failure and Preserved Ejection Fraction
Heart FailureThere are no studies specifically examining the effects of coenzyme Q (CoQ) treatment on echocardiographic indices of diastolic function in elderly patients with heart failure with preserved ejection fraction (HFPEF). In previous studies the only echocardiographic parameters studied were ejection fraction (EF) and chamber size. The objective of the proposed current study is to examine the effect of 16 weeks of ubiquinol therapy on diastolic function assessed by echocardiography in patients over the age of 50 with a clinical diagnosis of HFPEF. Ubiquinol (Kaneka Pharma), the reduced form of CoQ will be utilized for this study as it has been shown to have superior bioavailability when compared to oxidized CoQ.
Open Lung Strategy in Critically Ill Morbid Obese Patients
ObesityRespiratory Insufficiency3 moreThe goal of this interventional crossover study in morbidly obese intubated and mechanically ventilated patients is to describe the respiratory mechanics and the heart-lung interaction at titrated positive end-expiratory pressure levels following a recruitment maneuver with transthoracic echocardiography and electric impedance tomography imaging.
Bowditch Revisited: Defining the Optimum Heart Rate Range in Chronic Heart Failure
Chronic Heart FailureThe investigators are examining the relationship between heart rate and heart contraction in patients with heart failure and pacemakers, aiming to improve quality of life.
Reassure Remote Respiration Monitoring in Heart Failure Patients
Heart FailureThis study is designed to descriptively assess improvement in quality of life and test the usability of remotely monitored respiration parameters in the routine management of recently discharged heart failure patients. It will consist of two arms: (i) intervention, and (ii) control. Participants will be randomized to either arm at time of enrollment. Every participant enrolled in the study will receive a device for remote monitoring.
GutHeart: Targeting Gut Microbiota to Treat Heart Failure
Systolic Heart FailureThe objective of this trial is to study the effect of targeting the gut microbiota in patients with heart failure (HF). First, the investigators will characterize gut microbiota composition in patients with various degree of systolic HF as compared with healthy controls. Second, the potential impact of targeting gut microbiota to improve HF will be investigated through an open label randomized controlled trial (RCT) of probiotics, antibiotics and controls. The hypothesis being tested is that the gut microbiota is altered in HF; that gut microbiota of HF patients, through interaction with the intestinal and systemic innate immune system, contribute to a low-grade systemic inflammation as well as metabolic disturbances in these patients; and that an intervention with probiotics and the non-absorbable antibiotic Rifaximin attenuates these inflammatory and metabolic disturbances and improves heart function through modulation of the gut microbiota.
