NCT03299101
Frail Veterans are at increased risk for poor surgical outcomes, and as the Veteran population grows older and more frail, there is a critical need to identify effective strategies for reducing surgical risks for these patients. Prior research shows that inter-disciplinary rehabilitation strategies deployed after surgery enhance recovery and improve outcomes by building strength and improving nutrition. The investigators believe that similar improvements may be obtained by using similar interventions before surgery to "prehabilitate" patients' capacity to tolerate the stress of surgery. The proposed research will examine the feasibility of a new, home-based prehabilitation intervention aimed at improving surgical outcomes after cardiothoracic surgery through preoperative exercise training and nutritional supplementation. Findings from the study will inform the design of a larger randomized controlled trial of the prehabilitation intervention. If proven effective, prehabilitation could benefit as many as 42,000 frail Veterans who are scheduled for major elective surgery each year.
NCT00232180
In an earlier study, eplerenone was shown to improve survival in patients who had heart failure immediately following a heart attack. However, it is not known how patients with established mild-to-moderate heart failure (NYHA Class II), who have the additional risk of sudden death, will respond if treated with eplerenone. In this trial, eplerenone plus standard heart failure medicines is being compared to placebo plus standard heart failure medicines in terms of an additional ability to prolong life and prevent re-hospitalizations for worsening heart failure in these patients. The Data Safety Monitoring Committee (DSMC) observed during its conduct of the protocol-specified second interim analysis on the 6th of May, 2010 that the efficacy of eplerenone had met the pre-specified stopping rules in the protocol. As a result of the discussion between the DSMC and the Executive Steering Committee (ESC), the ESC recommended that EMPHASIS-HF should be terminated, Based on the convincing efficacy and the consideration that it would be unethical not to offer this treatment to patients, the ESC recommended that all the patients in the trial should be transferred to open-label eplerenone. The Open Label Extension eplerenone arm will last for 12 months. Eplerenone is not currently approved for the indication studied in this patient population. On May 26, 2010, further enrollment into EMPHASIS-HF was stopped. The amendment is considered to be the most appropriate way to ensure that all the subjects who participated in the double-blind phase of the EMPHASIS-HF trial can be offered treatment with eplerenone
NCT02290028
The QP ExCELs study is designed to confirm safety and efficacy of the BIOTRONIK Sentus OTW QP left ventricular leads to satisfy FDA requirements for regulatory approval of the leads in the US. The Sentus OTW QP leads received FDA approval on May 4, 2017. Long-term safety of the BIOTRONIK Sentus OTW QP left ventricular leads will be confirmed during the ongoing post approval phase (US sites only). A protocol update was implemented on September 6, 2019 to transition the long-term follow up for the ongoing Sentus QP Study to a new EP PASSION real-world data methodology.
NCT03035474
CONNECT-HF is a large-scale, pragmatic, cluster-randomized clinical trial to evaluate the effect of a customized, multifaceted, health system-level quality-improvement (QI) program compared with usual care on heart failure (HF) outcomes and HF quality-of-care metrics.
NCT03203629
To conduct a prospective, observational study to evaluate the non-interventional feasibility of using heart sounds measurements recorded by the LifeVest® Wearable Cardioverter Defibrillator (WCD) for monitoring clinical evidence of heart failure decompensation.
NCT03232944
The purpose of this Post-Approval Study (PAS) is to evaluate the effectiveness of MPP to improve CRT response in the non-responder patient population when used in "real-world" clinical practice, following commercial release. This evaluation is based on the Clinical Composite Score which summarizes the proportions and frequencies of CRT non-responder patients who are "improved", "unchanged" or "worsened" after receiving MPP therapy. Patients will be followed for the duration of the PAS. This study is required by FDA as a condition of approval of the MPP feature and is integrated within the Product Surveillance Registry (PSR).
NCT01361685
Lead survivability will be summarized.
NCT02696967
The purpose of this study was to determine the safety and tolerability of CLR325 intravenous (i.v.) infusion in patients with stable heart failure to determine if further clinical development of the drug in this indication was warranted.
NCT00082589
The purpose of this study is to determine if eplerenone is effective in the treatment of mild to moderate heart failure
NCT01951625
Objective of the study is to find the optimal dose of the once daily oral soluble guanylate cyclase stimulator (sGC) BAY1021189 for Phase III that can be given in addition to standard therapy for heart failure with reduced ejection fraction (HFrEF).
NCT01757067
Premature ventricular contractions (PVC) are a very common irregular heart beat (arrhythmias) even in patients without heart disease. Frequent PVCs are thought to occur in about 1-4% of the general population. Many patients with PVCs complain about skipping of their heart (palpitations), shortness of breath and feeling tired. In some patients PVCs may also result in weakening of the heart muscle (heart failure), which might be reversible with suppression of the PVCs.
NCT03350542
EVOLVE 48 is a prospective, open label, single arm, multi-center trial. The purpose of this study is to assess the FDA requirement for safety and effectiveness of the SYNERGY 48 mm Coronary Stent System for the treatment of subjects with atherosclerotic lesion(s) \> 34 mm and ≤ 44 mm in length (by visual estimate) in native coronary arteries ≥2.5 mm to ≤4.0 mm in diameter (by visual estimate).
NCT02874794
To determine whether treatment with sacubitril/valsartan provides a superior effect on aortic characteristic impedance compared to enalapril in patients with heart failure and reduced ejection fraction (left ventricular ejection fraction \[LVEF\] ≤ 40%) after 12 weeks of treatment. The primary endpoint is the change in aortic characteristic impedance (Zc = dP/dQ in early systole) between baseline and Week 12.
NCT02661217

NCT02232659
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.
