Active clinical trials for "Heart Failure"

Hospitalized patients with acute decompensated heart failure (ADHF) present a high prevalence of inspiratory muscle weakness on admission and discharge. Inspiratory muscle training has been reported as a beneficial approach in chronic heart failure. However, the effects of inspiratory muscle training in hospitalized patients with ADHF have been not known. The aim of this study is to investigate the safety, feasibility, and effects of inspiratory muscle training in hospitalized patients with ADHF.

An important feature of patients with HFpEF is impaired exercise tolerance, resulting in worsening and reduced quality of life. Studies in the literature on patients with HFpEF suggest that the limited transport of oxygen to the muscles can be one factor leading to the early development of fatigue during physical activity and reduced effort tolerance. A recent study also shows that patients with HFpEF have an increased susceptibility to both central and peripheral fatigue, suggesting that neuromuscular fatigue may be one of the main mechanisms limiting exercise in this population. Type 2 diabetes mellitus (T2DM), which affects 90-95% of diabetic patients, is a comorbidity of particular interest in heart failure (HF). In T2DM, as in HF, some observed an altered energy metabolism of the muscle and a shift in the type of muscle fibers. Hyperglycemia influences neuromuscular function and appeared to be one of the major causes of oxidative stress by affecting the intrinsic properties of the muscle (mitochondrial activity and function, myofilaments) related to the expression of force. The impact of diabetes on neuromuscular function is also linked to long-term complications such as diabetic peripheral neuropathy involving impairment of motor nerve conduction and vascular complications. This opens up a rather complex picture suggesting that T2DM in patients with HF could contribute to a further decline in muscle strength by further reducing the aerobic capacity of these patients. It seems, there are currently no studies in the literature evaluating how much the coexistence of T2DM impacts neuromuscular fatigue and strength in patients with HF. Thus, the primary aim of this study will be to evaluate the differences in central and peripheral neuromuscular fatigue - determined by a submaximal exercise protocol with intermittent isometric contractions - in two groups of patients with heart failure with preserved ejection fraction with or without type 2 diabetes mellitus. Secondary outcomes will be related to the investigation of the differences in NO-mediated vascular function induced by a single passive movement of the leg, in the energy cost of walking, and in muscle oxygenation between the two groups.

This is an observational registry, which main purpose is to assess sex-related differences in heart failure (HF) presentation, management, and prognosis in patients admitted to a hospital with a certain diagnosis of HF. The diagnosis will be based on European Society of Cardiology (ESC) definition of HF ( clinical syndrome characterized by symptoms and/or signs caused by a cardiac abnormality, that results in elevated intracardiac pressure and/or inadequate output at rest or exercise ). The sample will be obtained prospectively by recruitment of patients of two hospitals of Santiago de Chile.

This study builds on the tested and refined HEART Camp intervention which has been shown to improve long-term adherence to exercise in individuals diagnosed with heart failure. HEART Camp Connect enhances HEART Camp by delivering the coaching via videoconference and providing access to hospital-based exercise facilities and online exercise programming. This prospective study uses a 2-group, randomized repeated measures experimental design with 3 data collection points baseline, Month 3, and Month 6.

To find out whether left ventricular septal pacing (LVSP)-based cardiac resynchronization therapy (CRT) is superior to right ventricular apical pacing (RVAP)-based CRT in patients with failed left bundle branch pacing at the beginning of chronic heart failure.

The P-VALUE-AHF trial is a multicenter, randomized, open-label, parallel-group trial on the diuretic and decongestive effects of different diuretic escalation strategies in patients with acute heart failure and diuretic resistance. The main aims are to compare the diuretic efficacy of three therapeutic strategies in patients with acute heart failure and diuretic resistance. to assess the improvement in clinical congestion and to compare the symptom-relief among the different treatment regimens

The study objective is to evaluate the feasibility of the Doraya Catheter and measure clinical performance and safety endpoints, in ADHF patients deemed to have insufficient diuretic response.

Cardiology Research Dubrava registry is a prospective, single centre registry including patients with acute coronary syndrome with and without ST segment elevation, patients with heart failure who were introduced with SGLT-2 inhibitors, patients implanted with TAVI, patients with venous thromboembolism, patients with pulmonary embolism who underwent thromboaspiration procedure, patients implanted with ICD, CRT and conduction system pacing devices, as well as patients with atrial fibrillation who underwent pulmonary vein isolation and are prescribed with long-term anticoagulation therapy.

This study is a multicenter randomized controlled trial designed to recruit individuals in the pre-heart failure stage who have hypertension without concurrent diabetes. Participants will be randomly allocated in a 1:1 ratio into the empagliflozin group (10 mg daily) or the placebo group, and they will undergo a follow-up period of 6 months. The primary endpoint for evaluation will be the left atrial volume index. The secondary endpoints will encompass cardiac structure and function parameters, as well as biomarkers obtained from blood samples. These biomarkers will include indicators of fibrosis, inflammation, cardiac function, and routine blood parameters. The overarching goal of the research is to comprehensively assess the impact of empagliflozin on the cardiac structure and function of pre-heart failure patients with hypertension while delving deeply into the mechanisms through which it exerts its effects.

The goal of the trial is to study the effects of lavender essential oil on sleep quality, anxiety, and fatigue in patients with chronic heart failure. The main questions it may answer are effects of lavender essential oil on sleep quality effects of lavender essential oil on anxiety effects of lavender essential oil on fatigue Patients will be randomly divided into experimental and control groups, the control group will inhale essential coconut oil, and the experimental group will inhale lavender essential oil for four weeks. At baseline, on the 7th day, and 28th day, the sleep quality, anxiety, and fatigue will be evaluated.
