Active clinical trials for "Myocardial Ischemia"

This prospective, consecutive enrolment, single-arm study will enroll up to 15 patients with single de novo, Type A lesions < 10 mm in length and located in a native coronary artery with a reference vessel diameter of 2.75 mm - 3.0 mm as measured by both offline QCA and IVUS. All patients will receive a 3.0 x 14mm DESolve Stent loaded with approximately 40 mcg of Myolimus. Angiographic and intravascular ultrasound (IVUS) will be completed for all patients at baseline and at 6 months. Optical Coherence Tomography (OCT) will will be completed for all patients at baseline and at 6 months. Multi-slice computed tomography (MSCT) will be conducted on all patients enrolled at 12 and 24 months.

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.

The ABSORB III PK sub-study is a prospective, open-label, non-blinded study enrolling approximately 12 subjects in up to 5 US sites. ABSORB III PK sub-study is a part of ABSORB III RCT (NCT01751906). The objective is to determine the pharmacokinetics of everolimus delivered by the Absorb BVS in a separate and non-randomized cohort of subjects who only receive Absorb BVS with a maximum of two de novo native coronary artery lesions after implantation of the Absorb BVS. Note: The ABSORB III PK subjects will not contribute to the determination of the ABSORB III RCT primary endpoint.

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.

A Randomized Comparison of a Titanium-Nitride-Oxide Coated Stent (Helistent Titan2, Hexacath) With a Zotarolimus-Eluting Stent (EndeavorTm, Medtronic) for Percutaneous Coronary Intervention

The purpose of this study is to determine whether a paleolithic diet improves glucose tolerance and insulin sensitivity in people with coronary heart disease and impaired glucose tolerance.

European physicians tend to always use the lowest dose of statins to initiate therapy even in subjects who require large reductions in cholesterol. The study evaluates if selecting the starting dose based on baseline and target LDL-C cholesterol would provide better results (ie proportion of subjects resching target)

This proposal delineates a research plan to collect blood from the patients undergoing heart catheterization or have had a heart catheterization within one year, coming in for outpatient appointments, or have scheduled cardiac CT scans at the Cleveland Clinic over a five-year period for the purpose of establishing a gene bank registry. The University of North Carolina at Chapel Hill will enroll 1,000 non-Caucasian patients. MetroHealth Medical center in Cleveland will enroll 1,000 non-Caucasian patients. The blood collected will be processed to create a repository of DNA, lymphoblastoid cell line immortalization on selected patient populations, plasma and serum. The DNA will be amplified in certain patient populations to preserve the quantity. Along with a sample of blood collected from individual patients, a concise general medical history, demographic data, electrocardiographic data, echocardiographic data (available for about 55% of patients at the present time), and laboratory data will be collected. A short interview will take place after enrollment during the outpatient visit or hospital stay, or may be conducted via phone call after enrollment. All the clinical data gathered will be compiled in GATC heart center database, and would be stored in a format where a culmination of clinical findings, i.e. representing a disease of interest, can be used to search the database to identify the blood samples of all patients with such characteristics for further study.
