NCT00658515
This study will evaluate the potential of RO4607381 to reduce cardiovascular morbidity and mortality in stable coronary heart disease patients with recent Acute Coronary Syndrome (ACS) and evaluate the long term safety profile of the drug. Eligible patients in stable condition will be randomized to receive either RO4607381 600mg po or placebo po, daily, together with a background of standard medication for ACS (including aspirin, antihypertensives and statins). The anticipated time on study treatment is 2+ years, and the target sample size is 15,600 individuals.
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
NCT00082589
The purpose of this study is to determine if eplerenone is effective in the treatment of mild to moderate heart failure
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.
NCT04016740
The main purpose of this study is to determine whether a rational strategy of EEG guided multimodal general anesthesia using target specific sedative and analgesics could result in enhanced recovery after anesthesia and surgery, decrease in postoperative delirium, and decrease in long term postoperative cognitive dysfunction up to 6 months following cardiac surgery.
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.
NCT02503241
The 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.
NCT00632372
The purpose of this study is to collect and analyze electrical measurements, timing, and signals from a CRT-D device in heart failure patients who either already have an implanted left atrial pressure sensor or will undergo a simultaneous implantation of a left atrial pressure sensor and a CRT-D device. These devices may be placed at the same time or separately (staged procedure) at the discretion of the investigator. A comparison will be made between the information gathered from the CRT-D system and the information gathered by the left atrial pressure sensor.
NCT02605447
The EVOLVE Short DAPT Study is a prospective, multicenter, single-arm study designed to assess the safety of 3-month DAPT in subjects at high risk for bleeding undergoing PCI with a SYNERGY Stent System.
NCT03482973
The purpose of this study is to determine whether administration of a pecto-intercostal fascial plane block (PIFB) with bupivacaine is a more effective therapy for postoperative analgesia after cardiac surgery as compared to patients who receive a sham block of normal saline.
NCT03357731
The purpose of this study is to evaluate the effects of BMS-986231 on systolic and diastolic parameters in patients with heart failure and low ejection fraction.
NCT03548909
Amino Terminal pro-Brain Natriuretic Peptide (NTproBNP) is secreted in conditions of cardiac wall stress. NTproBNP levels are used in addition to clinical assessment to diagnose heart failure (HF). The purpose of this clinical study is to collect data to substantiate the use of the VITROS NT-proBNP II assay.
NCT02268942
This is a prospective, multi-center,single-arm study that will evaluate the thoracotomy implant technique in up to 145 subjects implanted via thoracotomy with the HeartWare HVAD System and enrolled in the Interagency Registry for Mechanically Assisted Circulatory Support (Intermacs®) protocol and database. All participating centers are current INTERMACS® sites in good standing and follow the INTERMACS® protocol and procedures.
NCT02351726
Prospective, non-randomized, multicenter post-approval study to collect long term clinical and echographic data on Mitroflow DL patients.
NCT03791320
The Multicenter FAST (Fast Assessment of STenosis severity) study is a prospective observational multicenter study designed to evaluate the diagnostic accuracy of offline 3D-QCA based FFR, using CAAS Workstation (Pie Medical Imaging, Maastricht, the Netherlands) in identifying hemodynamically significant coronary artery disease with pressure wire-based FFR (≤0.80) as the reference standard.
NCT02833948
The aortic valve is located between the left ventricle and the aorta. Patients with symptomatic, severe aortic valve stenosis conventionally have it surgically replaced requiring direct access to the heart through the chest. Transcatheter aortic valve replacement (TAVR) is now a well-established alternative for treating severe aortic valve stenosis. Both types of intervention improve prognosis and alleviate symptoms. The optimal choice of blood thinning therapy after TAVR is unknown. It has been reported that leaflet thrombosis with reduced leaflet motion can occur and this phenomenon has been suggested to be potentially related with neurological events. In addition, the occurence of this phenomenon can be reduced with anticoagulation blood thinning therapy. The purpose of this study is to evaluate if anticoagulation compared to the usual double platelet inhibitor therapy after TAVR can reduce the risk of leaflet thrombosis.
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).
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.
NCT02661217
To explore two modalities of treatment initiation (Pre-discharge, and Post-discharge) with LCZ696 in HFrEF patients following stabilization after an ADHF episode.
NCT02011061
Coronary calcium hampers accurate evaluation of the coronary arteries with coronary computed tomography angiography (CCTA). A novel approach to potentially overcome this limitation is coronary calcium subtraction. The primary hypothesis of the study is: \- Coronary calcium subtraction CCTA will improve diagnostic accuracy as compared to conventional CCTA on a per-patient basis
