NCT03687008
Adolescents with single ventricle heart disease (SVHD) (10 males and 10 females) with mild to moderate cognitive impairment will participate in a total of 25 computer-based working memory training sessions, each 30-40 minutes (5 days a week for 5 weeks) supervised by a trained coach. Primary objective is to evaluate the impact of the Cogmed intervention on working memory scores and the secondary objective to assess brain tissue changes with magnetic resonance imaging (MRI) using diffusion tensor imaging (DTI) techniques, measures of mean diffusivity pre- and post-intervention.
NCT02607748
The purpose of this study is to evaluate whether 18F-NaF (sodium fluoride) Positron Emission Tomography (PET) scans can be used to identify ruptured and high-risk plaque as compared to non-invasive coronary Computed Tomography Angiography (CTA) scans and high-definition intravascular ultrasound (IVUS). In subsets of patients, 18F-NaF PET scans and CCTA will be repeated to assess scan-rescan reproducibility.
NCT04157751
This is a study in adults who are in hospital for acute heart failure. The purpose of this study is to find out whether starting to take a medicine called empagliflozin soon after first being treated in hospital helps people with acute heart failure. Participants are in the study for about 3 months. At the beginning, participants are still in hospital. Later, they visit the hospital about 3 times and get 1 phone call. Participants are put into 2 groups by chance. One group takes 1 empagliflozin tablet a day. The other group takes 1 placebo tablet a day. Placebo tablets look like empagliflozin tablets but do not contain any medicine. Empagliflozin belongs to a class of medicines known as SGLT-2 inhibitors. It is used to treat type 2 diabetes. During the study, the doctors check whether participants have additional heart failure events like needing to go to the hospital again because of heart failure. The participants answer questions about how their heart failure affects their life. We then compare the results between the empagliflozin and placebo groups. The doctors also regularly check the general health of the participants.
NCT05140642
To determine whether an integrated AI decision support can save time and improve accuracy of assessment of echocardiograms, the investigators are conducting a blinded, randomized controlled study of AI guided measurements of left ventricular ejection fraction compared to sonographer measurements in preliminary readings of echocardiograms.
NCT02468778
The HeartMate PHP System is a temporary (\<6 hours) ventricular assist device indicated for use during high-risk percutaneous coronary interventions (PCI) performed electively or urgently in hemodynamically stable patients with severe coronary artery disease, when a heart team, including a cardiac surgeon, has determined high-risk PCI is the appropriate therapeutic option. Use of the HeartMate PHP Systems in these patients may prevent hemodynamic instability, which can result from repeat episodes of reversible myocardial ischemia that occur during planned temporary coronary occlusions and may reduce peri-and post-procedural adverse events.
NCT02836652
This study is a prospective, multi-center, randomized, double-blind placebo-controlled study of subjects receiving the HM II LVAD as per the current FDA approved indications for use.
NCT01452802
The purpose of this study is to evaluate and compare the effectiveness of the HeartMate II (HM II) Left Ventricular Assist Device (LVAD) support versus OMM in ambulatory NYHA Class IIIB/IV heart failure patients who are not dependent on intravenous inotropic support and who meet the FDA approved indications for HM II LVAD destination therapy.
NCT03570697
To evaluate the effect of evolocumab on fibrous cap thickness (FCT) in participants with non-ST-elevation acute coronary syndrome (NSTE-ACS) who are taking maximally tolerated statin therapy.
NCT01660035
The purpose of the REVERSE Post Approval Study (PAS) is to confirm the benefit observed in the REVERSE and RAFT pivotal studies in "real-world" clinical practice.
NCT04056104
The purpose of this research is to evaluate and create a new clinical prediction model for CCHD screening that combines non-invasive measurements of oxygenation and perfusion.
NCT04630067
This first-time-in-human (FTIH) study will be conducted to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of single doses of AZD3427 in healthy volunteers and multiple doses of AZD3427 in patients with heart failure (HF).
NCT02892955
The objective of the study is to continue to evaluate safety and clinical performance of the HM3 LVAS for the treatment of advanced, refractory, left ventricular heart failure following completion of enrollment in the the MOMENTUM 3 IDE Study.
NCT02224755
The objective of the study is to evaluate the safety and effectiveness of the HM3 LVAS by demonstrating non-inferiority to the HMII LVAS (HMII) when used for the treatment of advanced, refractory, left ventricular heart failure.
NCT03579641
The goal of the PREEMPT-HF study is to collect device and clinical event data to evaluate extended applications of the HeartLogic Heart Failure Diagnostic (HeartLogic) in a broad spectrum of heart failure patients with an implantable cardioverter defibrillator or cardiac resynchronization therapy defibrillator. There are no primary safety and/or efficacy endpoints for this study. Heart failure is a complex clinical syndrome with high morbidity, mortality, and economic burden. Chronic Heart Failure is persistent, gradually progressive, and punctuated by episodes of acute worsening leading to hospitalizations. Therefore, there remains an unmet clinical need to slow the progression of Heart Failure and prevent hospitalizations. HeartLogic, available in Boston Scientific cardiac resynchronization therapy devices and defibrillators, combines novel sensor parameters such as heart sounds and respiration with other measurements like thoracic impedance, heart rate, and activity into a HeartLogic Index for the early detection of worsening Heart Failure. However, there is limited data on the association of HeartLogic with the risk of Hear Failure readmissions and tachyarrhythmias, or for phenotyping the broad spectrum of Heart Failure patients.
NCT03988166
The objective of this study is to evaluate angiographic confirmation of placement of any guidewire beyond the CTO, in the true vessel lumen, in patients undergoing CTO percutaneous coronary intervention (PCI) in which at least one Teleflex guidewire and at least one Turnpike catheter are used.
NCT03084367
This is a pilot study designed to assess the relationship between iFR (instantaneous wave-free ratio) pullback and the distribution of coronary atheroma/stenoses as assessed by Quantitative Coronary Angiography (QCA) post angiographically successful PCI (Percutaneous Coronary Intervention).
NCT00121472
The purpose of this study is to determine the safety and effectiveness of the Thoratec HeartMate II Left Ventricular Assist System (LVAS) as a bridge to cardiac transplantation in end-stage heart failure patients who are listed for cardiac transplant but are at imminent risk of dying. The HeartMate II LVAS was approved by the US FDA on April 21, 2008, as a bridge to cardiac transplantation (reference PMA P060040). It was approved for commercial distribution in Canada on May 20, 2009 (reference Medical Device Licence #79765). Patients enrolled into the clinical trial will continue to be followed until all have reached a clinical outcome.
