NCT00088179
During a heart bypass procedure, a substance called "complement" is activated by the body. This "complement activation" causes an inflammatory response that can lead to side affects such as chest pain, heart attacks, stroke, heart failure, or death. The purpose of this study is to find out if the study drug (pexelizumab), that blocks "complement activation," can reduce such side effects and be given safely to patients requiring the bypass procedure with the use of the heart-lung machine.
NCT01663402

Other objectives include evaluating the overall safety, tolerability, and effectiveness of canagliflozin. The data from this study will be combined with the data from CANVAS-R study (Study of the Effects of Canagliflozin on Renal Endpoints in Adult Subjects with T2DM, NCT01989754) in a pre-specified integrated analysis of CV safety outcomes to satisfy US FDA post-marketing requirements for canagliflozin.
NCT01076348
Safety and effectiveness will be summarized for the model 4965 lead. This study was conducted within Medtronic's System Longevity Study (SLS).
NCT01826019
The overall objective of the HOPE-4 Phases (HT and CVD) is to develop, implement and evaluate an evidence-based, contextually appropriate programme for cardiovascular disease (CVD) risk assessment, treatment and control involving: (1) simplified algorithms implemented by non-physician health workers (NPHW) and supported by e-health technologies (tablets programmed with decision and counselling support software); (2) initiation of evidence-based cardiovascular (CV) medications and (3) treatment supporters to optimize long-term medication and lifestyle adherence.
NCT02595814
The clinical characteristics, initial presentation, management, and outcomes of patients hospitalized with new-onset (first diagnosis) heart failure (HF) or decompensation of chronic HF are poorly understood worldwide. REPORT-HF is a global, prospective, and observational HF disease registry designed to characterize patient trajectories longitudinally during and following an index hospitalization for acute HF.
NCT02188069
SCAD (Spontaneous coronary artery dissection - tear in the arterial wall that is not related to trauma) is an under-diagnosed and poorly understood condition that mostly affects young women without common cardiovascular risk factors, and can result in heart attack and death. This observational study is designed to capture the disease's natural history and predisposing arteriopathies (medical conditions resulting in changes in the arteries), treatment strategies, long-term cardiovascular outcomes. It will also improve the diagnosis of SCAD on coronary angiography by participating clinicians, and provide guidance on investigating predisposing conditions.
NCT02996903
The "Prospective Multicenter Registry On RadiaTion Dose Estimates Of Cardiac CT AngIOgraphy IN Daily Practice in 2017" (PROTECTION-VI) study is a prospective registry and investigator-initiated initiative without third-party funding, which will collect and analyze the radiation dose exposure of Cardiac Computed Tomography Angiographic (CCTA) studies in current daily practice worldwide. Particularly, the study will assess the use of strategies for dose reduction during CCTA. A decade ago, the multicentre observational PROTECTION-I study has revealed that the dose-length-product of CCTA ranges between 568 - 1259 mGy x cm with a median of 885 mGy x cm. This corresponds to an estimated effective dose of approximately 12 mSv. Since then a variety of techniques have been developed and enhanced in order to reduce radiation exposure during CCTA. Recent studies demonstrated feasibility of dramatically reduced effective radiation doses during CCTA (0,1 - 0,3 mSv). This has been executed in small cohorts of patients at scientific expert centers. However, it remains unclear, if such low-level radiation dose exposure may be achieved in clinical routine and if diagnostic image quality is maintained. In order to analyze the magnitude of radiation dose exposure of CCTA in today's clinical practice and the current use of dose-saving techniques, we designed the PROTECTION-VI study. Eventually, this study may contribute to further improving radiation dose exposure for patients undergoing CCTA.
NCT01500434
The purpose of this study is to evaluate the safety and effectiveness of the PROMUS Element™ Everolimus-Eluting Coronary Stent System for the treatment of patients with up to 2 de novo atherosclerotic coronary artery lesions. The lesions can be longer than average-sized.
NCT00683696
The EchoCRT trial evaluates the effects of Cardiac Resynchronization Therapy (CRT) on mortality and morbidity of subjects with heart failure due to left ventricular systolic dysfunction, already receiving optimized HF medication, with a narrow QRS width (\< 130 ms) and echocardiographic evidence of ventricular dyssynchrony.
NCT00458276
Endothelin-1 is a powerful substance that may be involved in causing hemodynamic instability (problems related to unstable blood pressure) during and after open heart surgery. Tezosentan is an investigational intravenous drug that blocks the endothelin receptors. This clinical trial will assess the potential benefit of tezosentan compared with placebo in the treatment of patients undergoing open heart surgery with cardiopulmonary bypass (CPB). Treatment time is from the start of surgery up to 24 hours.
NCT00116428
This trial compares the safety and effectiveness of catheter ablation for PAF with antiarrhythmic drug therapy. The investigational catheter being studied is the NAVISTAR® THERMOCOOL® irrigated-tip catheter. At the time of this study, the NAVISTAR® THERMOCOOL® catheter was FDA-approved for commercial distribution in the U.S. for treating patients with Type I atrial flutter and drug refractory monomorphic ventricular tachycardia post myocardial infarction. The catheter was approved for use in Europe for endocardial ablation for treating cardiac arrhythmias.
NCT00510198
The purpose of the PRECEDE-HF study is to collect data to compare patients whose heart failure is managed using Cardiac Compass with OptiVol (which is a tool in the device that records information about the heart that doctors can use to help treat their heart disease) combined with standard treatment methods (Access Group) to patients whose heart failure is managed by standard treatment methods only (Control Group). This comparison will show if the additional monitoring provided by Cardiac Compass with OptiVol delays the time patients are first admitted to hospital for heart failure or delays the time to death.
NCT00500617
The PREDICT study is to develop and validate a diagnostic blood ASGES (age, sex, gene expression score) or Corus CAD for atherosclerotic coronary artery disease (CAD). The Corus CAD (Age/Sex/Gene Expression score - ASGES) will use quantitative real-time PCR (RT-PCR) to quantify the expression of multiple genes from circulating peripheral blood cells to assess the presence of clinically significant CAD in a patient.
