Filter by:Patients with advanced (ACCF/AHA stage D) heart failure and hyperuricemia have high one-year mortality. Currently, there was no evidence-based therapy such as mechanically assisted circulatory support available in China. The investigators found glucocorticoid treatment such as prednisone could improve cardiac performance, potentiate renal responsiveness to diuretics in such patients. Therefore, it could be used as bridge therapy to help ACE inhibitors or beta blocker titration. With its help, most of the patients with stage D heart failure could be titrated to higher dose of ACE inhibitors and beta blockers during hospitalization. However, the efficacy of long-term, low-dose of prednisone use in such patients with limited life expectancy remain unclear. Therefore, the investigators designed this study to observe whether putting low-dose of prednisone on the patients with stage D heart failure for long term could further improve their survival. All patients will receive prednisone treatment during hospitalization and receive maximum tolerated guideline-directed medical therapy (GDMT). After discharge from hospital, the patients will be randomized to receive long-term, low-dose prednisone treatment or standard GDMT.
Although current pharmaceutical therapies have improved the survival rate in heart failure it remains a fatal disease and is associated with a poor 3-year survival. Increased sympathetic activity found in patients with heart failure plays an important role in the pathogenesis and development of the disease[Provide reference]. Excessive activation of sympathetic tone contributes to arrhythmogenesis, increased cardiac wall tension, and platelet aggregation, promoting a "vicious cycle[What cycle? Elaborate. ]" in these patients. High thoracic epidural anesthesia (HTEA) can reversibly and regionally block the cardiac sympathetic nervous system. The method was pioneered by Prof. Liu Fengqi in 1995, and he has accumulated clinical experiences from thousands of cases. His anecdotal experience indicates that the method can favorably improve intractable angina, dilated cardiomyopathy, and advanced heart failure. Though the method has been used to treat patients at our center for many years, there has been no prospective trial of its effects on cardiovascular function, or its efficacy to improve clinical outcomes. The investigators propose to investigate the immediate physiologic effect and clinical effectiveness of HTEA in treating heart failure.
The aim of this study is to determine whether a nurse-managed telephone-based disease-management intervention can reduce healthcare utilization and improve self-assessed health status in patients with congestive heart failure.
Sympathetic hyperactivity is a causal or a promoting factor in many diseases, under these conditions, some morphology changes due to the hyperactivity occur. Renal nerve is an important part in the autonomic nervous system regulation, especially in cardiovascular system, the modulation of the renal nerves used as a therapeutic strategy has been researched across the world. The purpose of this study is to evaluate and quantify the morphology changes in different diseases, make the modulation therapy more selective and effective.
This is the first study assessing the impact of dexamethasone (a glucocorticosteroid with negligible mineralocorticoid activity) as compared to prednisone on short-term outcomes of HF patients hospitalized with exacerbation of COPD. The study may provide important data regarding a simple but potentially robust intervention among large patient population with high rates of hospital admissions.
Study aims to compare the I(f) inhibitor ivabradine with placebo as strategy of heart rate control in patients with decompensated heart failure (DHF).
Purpose of the observational study is to assess the capability of a satellite tele-echocardiography (STE) system to acquire and transmit echocardiographic images and clips to an echocardiographic core laboratory (ECL) in a real time mode without loss of quality. Additionally the prognostic efficacy of specific echo parameters in the cardiac resynchronization therapy response will be evaluated.
The SynCardia 70cc temporary Total Artificial Heart (TAH-t) is approved by the U.S. Food and Drug Administration (FDA) for use as a bridge to transplant for patients at risk of imminent (about to happen) death from irreversible biventricular heart failure. The purpose of this research study is to evaluate whether the TAH-t can support patients with life-threatening irreversible biventricular heart failure who are not eligible for transplantation. The TAH-t, when used for patients who are not eligible for transplant, is considered to be an investigational (not approved by FDA) use. This use is called destination therapy (DT). Nineteen (19) patients with life-threatening, biventricular failure who are not eligible for cardiac transplant will be enrolled in the Primary Arm of the study and followed for up to six months post-TAH-t implant. Safety will be evaluated by reviewing the adverse events that are experienced by the enrolled subjects and comparing them to previous experience of TAH-t patients who were waiting for a heart transplant. Since approximately 74% of patients with this condition would not be expected to live beyond six months, the benefit of the TAH-t for DT will be confirmed based on survival to six months without experiencing permanent disabling stroke-related deficits. After the six month follow-up visit, patients will continue to be followed under the study for up to five (5) years postTAH-t implant [every six months for up to two years while supported with the TAH-t implant and then annually for another three years]. Up to an additional 19 patients may be enrolled in the Secondary Arm of the study to further characterize the use of the TAH-t for DT in a broader patient population. Follow-up would be the same for patients enrolled in both arms of the study.
To investigate the occurrence of arrhythmias in dental treatment with local anesthetic.
Sleep disordered breathing, in which patients my breath deeply, shallowly or stop breathing for periods whilst asleep, is common in heart failure and associated with a poor prognosis. This study aims to validate a novel function available on certain pacemakers which is designed to detect this condition.The investigators hypothesize that ApneaScan can accurately detect moderate to severe sleep disordered breathing in patients with heart failure as compared against an Embletta sleep study. The investigators will also follow up our patients for 2 years to determine whether the severity of sleep disordered breathing as assessed by ApneaScan correlates with prognosis.
