Active clinical trials for "Heart Failure"

Acute heart failure (AHF) is a common discharge diagnosis in the emergency department (ED), associated with 1-month mortality of 6%, and a 30% risk rate of 1-month rehospitalisation. Current guidelines recommend the use of nitrates and low dose diuretics to treat congestion, but to date, no drug has ever shown any improved clinical outcome when given at the acute phase. Several studies suggest that there is a high inflammatory component in AHF, with elevated markers such as IL6 and C-reactive protein (CRP). As it is the case in other acute respiratory disease, a short course of steroid therapy may limit the inflammatory response and in turn, improve AHF prognosis. The objective of the study is to assess the effect of a 7-day course of steroid introduced in the ED on inflammatory response

Atrioventricular node ablation (AVNA) with biventricular (BiV) pacemaker implantation is a feasible treatment option in patients with symptomatic refractory atrial fibrillation and heart failure. However, conduction system pacing (CSP) modalities, including His bundle pacing and left bundle branch pacing, could offer advantages over BiV pacing by providing more physiological activation. The randomized, interventional, multicentric study will explore whether CSP is non-inferior to BiV pacing in echocardiographic and clinical outcomes in heart failure (EF <50%) patients with symptomatic AF and narrow QRS scheduled for AVNA.

This trial is a prospective, multicenter, single-group target-value clinical trial in which patients with chronic left heart failure are planned to be recruited. Using the atrial shunt implantation system developed and produced by Morningside (Nantong) Medical Device Co., Ltd., the atrial septum is used to implant the instruments in the atrial septum. to verify the safety and efficacy of the atrial shunt implant system for the treatment of patients with chronic left heart failure.

Cardiac resynchronization therapy (CRT) is an established therapy for symptomatic heart failure patients. However, there are still 30 to 40% of studied patients being nonresponder to CRT. The plausible reasons of lack of effect of CRT in these patients include relative less baseline electrical dyssynchrony. The aim of our study is to investigate whether there is an optimal configuration of CRT delivery that varies between patients with different pattern of activation delay.

Background Cardiac Resynchronization Therapy (CRT) is proven to improve survival and heart function of patient with certain electrical conduction abnormality and heart failure. However, in patient with certain electrical conduction abnormality, being nonresponder is observed in up to 40% in patient receiving CRT. Conventionally the surgical approach of CRT is to implant one pacing lead in the right heart and one in the left heart to resynchronize the contraction and the pacing lead in the left heart is usually placed in the posterior or lateral portion of the left heart. However, this single approach may not be optimal, especially for those patients with conduction abnormality known to have no response to CRT. Purpose of the clinical investigation. The purpose of the Electrical Activation Guided CRT for Nonresponders Study is to study the effectiveness of an addition of Hisbundle pacing approach to CRT nonresponder by direct His-bundle pacing to improve the responder rate of nonresponder of conventional CRT and a tailored made approach to CRT procedure by using a noninvasive globally mapping system studying the electrical conduction under different approaches to delivery CRT. The pacing approach that optimally corrects conduction abnormality will be determined before the actual addition of new lead procedure. Conduct of the Investigation This study will include 18 patients already implanted with device delivering conventional CRT that known to have no response to the conventional CRT after 6 months of the CRT therapy from Prince of Wales Hospital, Hong Kong. You will be followed in the device clinic as per usual care after your participation in the study is completed.

This is a multicenter, randomized controlled study. This study aims to compare the clinical efficacy of LBBAP with traditional biventricular pacing in patients with permanent atrial fibrillation and heart Failure

The main purpose of this study is to assess the efficacy and safety of LY3540378 in adults with worsening heart failure with preserved ejection fraction

Data regarding the safety and efficacy of ivabradine use in severely decompensated HFrEF requiring inotropic support is limited to case series.1 This study aimed to evaluate ivabradine safety and tolerability in admitted cardiogenic shock patients who started on dobutamine infusion for inotropic support.

The purpose of this study is to conduct a multicenter, randomized clinical trial to evaluate the effect of "Shengxian Quyu Decoction" on quality of life , symptoms, and biomarkers in heart failure patients with reduced ejection fraction.

The heart is a pump that must both fill and empty effectively to move blood; if it cannot move enough, heart failure may ensue. Approximately half of all adults living with heart failure have a form where the heart stiffens, which impairs its ability to fill. This form of heart failure particularly affects females and older adults. When people exercise, extra blood returns to the heart. The healthy heart can easily fill and move this extra blood to the muscles. However, when the heart's ability to fill is impaired, the extra blood can back up and pool in the lungs. Blood pooling in the lungs makes people feel breathless, although the investigators do not fully understand why, and this form of heart failure has a high risk of hospitalization and death, but few effective treatments are available. Exercise is one of the few treatments that works well if enough exercise is performed regularly. However, many people with this form of heart failure can only tolerate a small amount before stopping due to severe breathlessness, which can put them off from exercising regularly. The study's goal is to help these people perform more exercise. The investigators will use a novel form of stationary cycling with a plastic chamber around the lower body that seals at the waist. The chamber can apply suction to the lower body during exercise which will reduce how much extra blood returns and prevent the heart and lungs from being overloaded. Participants will attend 5 visits, including 3 where they will perform a submaximal exercise test for as many minutes as possible with or without light suction. In each of these tests, the investigators will record how long they exercise and ask them to rate how breathless they feel. The investigators will also study their breathing pattern, using a mouthpiece and pressure sensor, and heart function, using ultrasound imaging. This work will help adults living with heart failure exercise more and improve their health, and help researchers understand what causes breathlessness and develop new treatments.
