Active clinical trials for "Coronary Artery Disease"

The aim of the DARE study is to see whether strict glycemic control during cardiac rehabilitation may ameliorate the improvement of exercise capacities (VO2 peak, peak workload, ventilatory threshold)in patients with type 2 diabetes with coronary artery disease.

TAXUS ATLAS Direct Stent is a global, multi-center, single-arm, noninferiority trial comparing results from patients in whom the TAXUS Liberté stent was directly implanted (direct stenting) versus results from patients in whom implantation with the TAXUS Liberté stent was preceded by balloon angioplasty (pre-dilatation). The Control group consists of patients in the main TAXUS ATLAS trial, in which pre-dilatation was mandatory. The primary objective is to compare outcomes of direct stenting with balloon catheter pre-dilatation. The primary hypothesis is that late outcomes with direct stenting of the TAXUS™ Liberté Paclitaxel-Eluting Coronary Stent System will be non-inferior to conventional implantation with balloon catheter pre-dilatation

The primary objective is to evaluate if use of the AngioGuard™ XP improves myocardial reperfusion after PTCA as assessed by ST segment resolution at the end of PTCA.

The sponsors of this investigational drug are developing prasugrel (also known as CS-747) as a possible treatment for patients with acute coronary syndrome (heart attack or chest pain) who need, or are expected to need, a percutaneous coronary intervention (PCI; also called a balloon angioplasty). Prasugrel was compared with Clopidogrel to determine which drug is better at reducing deaths, future heart attacks, or stroke.

This study is designed to compare two different echocardiographic techniques in the evaluation of heart disease (coronary artery disease). Both tests called Myocardial Contrast Echocardiography with Pharmacologic Stress and Stress Echocardiography with Dobutamine, are performed using a standard echocardiographic machine. Myocardial Contrast Echocardiography (MCE) does not use radioactivity. It uses sound waves like standard echocardiography. However, with MCE patients receive an injection of a "contrast agent" directly into the blood stream through a vein. The contrast agent, called Optison, is made of tiny microbubbles smaller than red blood cells. The echocardiogram can detect these microbubbles in the small blood vessels of the heart muscle and allow researchers to find areas of the heart receiving less blood flow than others. It is important to observe the heart during exercise because there are changes in blood flow. Since MCE cannot be performed when the patient is exercising, researchers give medication (adenosine) that stimulates the heart and creates a situation similar to exercise. Stress Echocardiography with Dobutamine does not use radioactivity. It uses sound waves like standard echocardiography. During this echocardiogram patients receive doses of a medication called dobutamine that stimulates the heart to beat stronger and faster. The purpose of this study is to evaluate the accuracy of MCE compared to stress echocardiography at detecting coronary artery disease (CAD).

This study is designed to characterize the pharmacokinetics of multi-dose RVX000222 and atorvastatin and rosuvastatin when either statin is administered in combination with RVX000222 in subjects with dyslipidemia.

The clinical effects of intra-operative radiofrequency ablation in patients with persistent or permanent atrial fibrillation and an indication for an implantation of a heart valve prosthesis or coronary bypass surgery are the purposes of this study. The study will examine if and to what extent the quality of life and the use of medical care differs between patients with and without ablation. Furthermore, there will be thorough echocardiographic examinations of the heart to detect differences between the different treatment groups. The patients will be followed for one year after treatment.

The target enrollment goal for the trial was to enroll 36 subjects. However due to a challenging protocol inclusion/ exclusion criteria, only one subject was enrolled since the trial was initiated in June 2011. To evaluate the following in participants undergoing coronary artery scaffolding/stenting for significant coronary artery disease: The acute (post-implantation) effect of an implanted bioresorbable vascular scaffold (BVS) or metallic drug eluting stent (mDES) on coronary blood flow and physiological responsiveness of the target coronary artery The long-term (2 years) effect of an implanted BVS or mDES on coronary blood flow and physiological responsiveness of the target coronary artery

To evaluate product performance and safety of the Catheter Design for the treatment of a single coronary lesion.

As part of National Institutes of Health Rapid Acceleration of Diagnostics-Underserved Populations (RADx-UP) program, the goal of the RADxUP study is to develop, test, and evaluate a rapid, scalable capacity building project to enhance COVID-19 testing in three regional community health centers (CHCs) in San Diego County, California. In collaboration with CHC partners, their consortium organization, Health Quality Partners (HQP), investigators are pursuing the following Specific Aims: 1) Compare the effectiveness of automated calls vs text messaging for uptake of COVID-19 testing among asymptomatic adult patients with select medical conditions and those 65 years of age and older receiving care at participating CHCs. Secondarily, investigators will invite all study participants to receive flu vaccination and will assess feasibility and acceptability of study participants to refer adult family household members who are essential workers for COVID-19 testing. 2) Gather patient, provider, CHC leadership, and community stakeholder insights to establish best practices for future scale-up of COVID-19 testing sustainability and vaccination.
