Active clinical trials for "Myocardial Ischemia"

The purpose of this study is to evaluate the potential benefit of systematic preoperative coronary angiography followed by selective coronary artery revascularization on the incidence of myocardial infarction (MI) in patients without a history of coronary artery disease (CAD) and undergoing carotid endarterectomy (CEA).

The aim of this randomized study is to evaluate the impact of Optical frequency domain imaging (OFDI) guidance for Percutaneous Coronay Intervention (PCI) with drug-eluting stent (DES) as compared with Intravascular ultrasound (IVUS) guidance.

Minimally invasive revascularization of the left anterior descending artery followed by stent implantation versus percutaneous coronary intervention or coronary artery bypass in patients with multi-vessel coronary disease

This study enrolled participants with documented exercise-induced myocardial ischemia in order to evaluate whether ranolazine, when taken prior to exercise, can improve blood flow to the heart (myocardial perfusion), as assessed by exercise-induced myocardial perfusion defect size (PDS) and total perfusion deficit (TPD), using gated single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI). This was a 2-period crossover study. The last dose of each period must have been taken 3-4 hours prior to conduct of the exercise SPECT MPI. After the research exercise SPECT MPI was performed at the end of Period 1, participants discontinued the treatment they were randomized to for that period and began the other treatment in Period 2.

The Tryton Side Branch Stent System has been designed to address the procedural difficulty surrounding treatment of bifurcation lesions and to ensure patency of the side branch with similar performance capabilities (e.g., tracking, radiopacity, coverage and radial strength) that are currently available with conventional coronary stents designed for straight (non bifurcation) lesions. The Tryton Side Branch Stent is intended to treat and maintain patency in the side branch/carina by providing better ostial side branch conformability and is intended for use in conjunction with currently approved balloon-expandable drug-eluding stents for treatment of the main branch.

The purpose of this study is to compare the one-time application of Paclitaxel from SeQuent Please (Paclitaxel-coated Balloon Catheter) after using the Coroflex Blue (Cobalt Chromium Stent) with the slow releasing of small dose of Paclitaxel from the Coroflex Please (Paclitaxel-Eluting Stent) stent system in a non-inferiority trial.

Evaluate the impact of systematic nursing orientations in the reduction of predicted cardiovascular risk in patients with coronary artery disease during four nursing visits for a 1-year period and compare to a group of patients submitted to conventional treatment.

Compile acute (30-day) clinical outcomes data and 9-month angiographic and intravascular ultrasound (IVUS) data for the PROMUS Element™ Everolimus- Eluting Coronary Stent System in the treatment of patients with a single de novo atherosclerotic lesion

To compare treatment with aspirin alone versus the combined antiplatelet treatment aspirin and clopidogrel after 12 months of combined antiplatelet treatment following drug-eluting stent (DES) implantation.

This trial is designed as a phase 2 randomized, double-blind double dummy, active comparator controlled, two-period two-arm crossover study to enroll 40 patients across multiple centers. The study will compare platelet function following a prasugrel loading dose and 1 week of prasugrel maintenance therapy with high-dose clopidogrel loading dose and 1 week of high-dose clopidogrel maintenance therapy in patients with drug treated type 2 diabetes mellitus who have coronary artery disease. Various assays of platelet function will be used in this study. Platelet function will be studied using the following assays: Accumetrics VerifyNowTM P2Y12, Light Transmittance Aggregometry (LTA), Vasodilator-associated stimulated phosphoprotein (VASP), and Thromboelastography (TEG)-platelet mapping.
