NCT01059682
This multicenter, double-blind, randomized, placebo-controlled study will evaluate the effect of dalcetrapib 600 mg on artherosclerotic disease progression, lipid profile and biomarker profile and long-term safety profile of dalcetrapib in patients with coronary artery disease. Atherosclerotic disease progression will be measured 1. Coronary Intravascular Ultrasound (IVUS), Quantitative Coronary Angiography 2. Carotid B-Mode Ultrasound Intima Medial Thickness (IMT) and total plaque volume in subjects undergoing coronary angiography who have coronary artery disease (CAD). Patients will be randomized to receive dalcetrapib 600 mg orally once a day or placebo. The anticipated time on study treatment will be 24 months. The target sample size is 800-1000 patients.
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.
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.
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.
NCT02961946
To evaluate image quality of coronary CT angiography (cCTA) after sublingual and transdermal administration of Nitroglycerin. Aim of this prospective research study is to investigate equivalence on image quality after sublingual or transdermal Nitroglycerin administration (H0). Furthermore, the feasibility of transdermal Nitroglycerin administration will be evaluated.
NCT00795717
The purpose of this study is to determine whether fish oil supplementation with Lovaza, formally known as Omacor will result in a significant reduction in serum triglyceride (TG), an increase in high density lipoproteins(HDL), and an improvement of endothelial dysfunction.
NCT02988115
The purpose of this study is to determine if bempedoic acid (ETC-1002) is effective and safe versus placebo in patients with elevated LDL cholesterol and who are statin-intolerant.
NCT02666664
The purpose of this study is to see if ETC-1002 (bempedoic acid) is safe and well-tolerated versus placebo in patients with high cardiovascular risk and elevated LDL cholesterol that is not adequately controlled by their current therapy.
NCT02351726
Prospective, non-randomized, multicenter post-approval study to collect long term clinical and echographic data on Mitroflow DL patients.
NCT02053038
Narrowing of coronary arteries interferes with blood flow and can cause chest pain. But patients may have more than one narrowing and studies have shown that not all narrowings need to be treated. To identify the narrowings that need treating cardiologists sometimes quantify the extent of the narrowing by measuring fractional flow reserve (FFR, the ratio of the pressure in the aorta to the pressure downstream of the narrowing).This technique requires the administration of drugs that add cost and time to the procedure and in some countries are simply unavailable. As a result despite the clear health and healthcare costs benefits of FFR its use is limited to less than 5% of procedure. We have developed a new technique called the instantaneous wave-free ratio (iFR) that does not require the administration of drugs for its accurate assessment. It has been approved for use in this indication. This study aims to compare clinical outcomes of patients whose treatment has been guided by iFR to those whose treatment has been guided by FFR. If iFR is found to provide the same clinical outcomes as FFR its adoption will permit the clear benefits of this approach of identifying the coronary narrowings that really need treatment to be applicable to a much larger patient population and further improve healthcare costs.
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.
NCT02757976
This trial will compare two strategies for patients with Heart Failure, Left Ventricular systolic dysfunction, and intermediate QRS durations. The control group is conventional CRT. The experimental group is LVendo CRT
NCT01281384
Uncovering the underlying cause of heart failure can be quite challenging and doctors often rely on imaging tests such as echo (heart ultrasound) to provide the answers. Cardiac MRI is emerging as another promising test because it gives very precise information on heart function and the amount of scarring in the muscle. Heart failure patients are increasingly being sent for cardiac MRI but the potential advantage that this test offers over others such as echo has not been fully explored. The purpose of this study is to determine if cardiac MRI provides more information on the cause of heart failure than traditional tests such as echo. In addition, if the information provided by this test always leads to an overall improvement in a patient's heart condition over time. This is a randomized study where subjects referred for clinically indicated heart failure workup to determine the best clinical management will undergo standard heart failure testing (including echo) OR standard testing PLUS cardiac MRI.
NCT01323153
This double-blind, randomized, placebo-controlled, multi-center study will evaluate the safety and efficacy of dalcetrapib in patients hospitalized for an acute coronary syndrome (ACS). Treatment will be initiated within 1 week after the ACS. Patients will be randomized to receive dalcetrapib 600 mg as daily oral doses or matching placebo. The anticipated time on study treatment is 20 weeks.
NCT03098979
