NCT03084367

NCT02910635
The primary objective of this study is to assess the corrected QT interval (QTc) effect of volanesorsen (ISIS 304801) administered as a 300 mg subcutaneous (SC) therapeutic and a 300 mg intravenous (IV; 2-hour infusion) supra-therapeutic dose relative to placebo in healthy adult male and female subjects.
NCT01925794
This is a prospective, multi-center, non-randomized, single arm clinical trial that will be conducted at up to 40 sites in the United States and Outside United States (OUS). This study will enroll patients with symptomatic ischemic heart disease due to a single de novo lesion contained within a native coronary artery with reference vessel diameter between 2.5 mm and 4.0 mm and lesion length ≤ 24 mm that is amenable to percutaneous coronary intervention (PCI) and stent deployment. All patients will be followed at 30 days, 6 months, 9 months, 1 year and annually for 5 years post index stenting procedure.
NCT03102437
This is a multicenter, prospective, single-arm Continued Access study of the Optimizer Smart System with CCM therapy.
NCT03038620
This study is a clinical study to investigate the efficacy of liraglutide compared to placebo in reducing visceral adiposity measured by MRI in overweight or obese subjects at high risk for cardiovascular disease after 40 weeks on-treatment.
NCT02929329
The purpose of this study is to determine if treatment with omecamtiv mecarbil when added to standard of care is well tolerated and superior to placebo in reducing the risk of cardiovascular death or heart failure events in adults with chronic heart failure with reduced ejection fraction (HFrEF).
NCT02104817
The study is a randomized, double-blind, placebo-controlled (corn oil), parallel group design that will enroll approximately 13,000 patients with hypertriglyceridemia and low HDL and high risk for CVD to be randomized 1:1 to either corn oil + statin or Epanova + statin, once daily, for approximately 3-5 years as determined when the number of MACE outcomes is reached.
NCT03057977
The aim of the study is to investigate the safety and efficacy of empagliflozin versus placebo on top of guideline-directed medical therapy in patients with heart failure with reduced ejection fraction.
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).
NCT04648306
A multi-center, prospective, observational, non-interventional single arm, study of the intermediate-term clinical outcomes collected from electronic health records of high-risk patients which have previously undergone standard of care prophylactic Impella support for a non-emergent percutaneous coronary intervention (PCI).
NCT00819793
The purpose of the study is to evaluate the safety and effectiveness of the CentriMag ventricular assist system to help patients who have experienced heart failure during surgery and cannot be removed from cardiac bypass.
NCT01850082
Coronary artery bypass grafting (CABG) is the most common major surgical procedure in the United States with over 300,000 cases performed each year. To restore blood flow to the heart, vascular conduits from another part of the body are procured to create a bypass around critically blocked coronary arteries. The left internal thoracic artery is the conduit of choice for CABG due to its superior long-term patency. However, almost all patients referred for CABG require additional grafts to provide complete revascularization. This necessitates the harvest of other vessels, most commonly the saphenous vein which is used almost ubiquitously in contemporary CABG with an average of two vein grafts per CABG procedure. In the last 10 years, Endoscopic Vein Harvesting (EVH) has been recommended as the preferred method over the traditional open harvesting technique (OVH) because it provides a minimally invasive approach. However, more recent investigations indicate potential for reduced long-term bypass graft patency and worse clinical outcomes with EVH. The long term impact of EVH on clinical outcomes has never been investigated on a large scale using a definitive, adequately powered, prospective Randomized Controlled Trial (RCT) with long-term follow-up.
NCT02552238
The purpose of this study was to assess the safety and efficacy of Lumason-enhanced dobutamine stress echo (DSE) in subjects having a suboptimal left ventricular endocardial border delineation (LV EBD) at rest and who were scheduled for coronary angiography.
NCT05185232
Congenital heart defects (CHDs) are a heterogeneous group of rare diseases of varying severity, each diagnosis with its unique set of co-morbidities. In addition to the heterogeneity, perhaps the greatest challenge to conducting comparative effectiveness research in CHD patients are the poor rates of successful transition from pediatric to adult centered cardiology care and high rates of gaps in recommend care for adults with CHD. This study will use PCORnet to examine the effects of gaps in recommended care (cardiology visits) on patient prioritized outcomes for adults with non-complex and complex subtypes of CHD. This system will be established through 14 (12 recruiting) PCORnet affiliated institutions and linkage to the Congenital Heart Initiative registry (https://chi.eurekaplatform.org), the first patient powered registry for adults with CHD. This registry launched in December 2020, and is IRB approved at Children's National Hospital (IRB# Pro00014697). Funded by PCORI, this project will recruit patients at the 12 PCORnet affiliated institutions and will invite them to contribute their health records data and then join the established Congenital Heart Initiative. By enrolling patients and linking their PCORnet (health record) data into an existing adult congenital heart disease (ACHD) specific registry, future interventions to reduce gaps in care based on study findings can be rapidly implemented in real-world settings through the strong partnerships established with key CHD stakeholders.
NCT02026466
This is an observational registry, sponsored by Saint Luke's Hospital. This study is to be conducted according to DHHS Guidelines, applicable state regulations, and local IRB policies and procedures. The overall objective is to address current gaps in knowledge regarding CTO-PCI, as a prospective, multi-center, single-arm study of 1,000 participants.
NCT04828590

The primary objective of this multi-center clinical validation study is to validate the clinical performance of DEEPVESSEL FFR in identifying patients with myocardial ischemia due to significant obstructive coronary artery diseases.
