Active clinical trials for "Coronary Artery Disease"

The purpose of this study is to evaluate the safety, efficacy and deliverability of the CRE8 sirolimus-eluting stent system in the treatment of patients with de novo coronary artery lesions.

Self-apposing, drug-eluting Stentys coronary stents represent a valuable tool for the treatment of coronary artery stenosis. Their ability to adapt to widely varying vessel calibers and to auto-expand after their release to self-appose to vessel walls is particularly useful in the presence of ectasic coronary arteries or significant vessel tapering. The investigators planned this study to assess the feasibility, the effectiveness and the safety of the implantation of self-apposing, drug-eluting Stentys stents for percutaneous coronary intervention. Consecutive patients undergoing percutaneous coronary intervention with implantation of a self-apposing Stentys stent were enrolled in this multi center registry. Inclusion criteria were age ≥ 18 years and ability to provide informed consent. No exclusion criteria were defined. Primary end-point of the study is the occurrence of MACE (death, myocardial infarction, stent thrombosis, unplanned hospitalization for unstable angina, target lesion revascularization). Secondary end-points include individual components of MACE, procedural complications (periprocedural MI, bleedings, access site complication, failure to cross stent struts with guidewire in the treatment of bifurcation, failure to delivery the stent, contrast-induced nephropathy), bleedings at follow up.

The present study hypothesizes that the systematic use of bilateral internal mammary artery (BIMA) grafting is feasible in the practice of a University Cardiac Surgery Institution for the treatment of multivessel coronary artery disease (primary hypothesis). The secondary study hypothesis is that the BIMA grafting meets the safety endpoint compared with the conventional surgical strategy entailing left mammary artery grafting plus great saphenous vein grafts to revascularize the remaining coronary targets. The tertiary study hypothesis is that the BIMA grafting yields better follow-up results in terms of recurrence of symptoms related to coronary disease, of repeat revascularization and of cardiac mortality compared with patients treated with the conventional surgical strategy entailing left mammary artery grafting plus great saphenous vein grafts to revascularize the remaining coronary targets.

This cardiac registry study will collect information from patients with ischemic or non-ischemic heart failure that have been treated with adipose-derived regenerative cells (ADRCs) delivered via intramyocardial injection.

This is a multi-center, investigator initiated study that will prospectively examine treatment strategies and outcomes of patients who underwent clinically-indicated Near Infrared Spectroscopy (NIRS). The information collected will be used to determine the frequency of NIRS imaging performed at the participating sites and to examine the clinical outcomes of the NIRS-detected Lipid Core Plaques (LCPs).

NSTE-ACS patients are more likely to exhibit high-risk plaque characteristics in non-culprit lesions. Both IVUS and OCT imaging techniques interact in a complementary manner to provide morphological characterization of the atherosclerotic coronary plaques and help identification of high-risk vulnerable plaques. Using morphological parameters obtained from OCT and IVUS, a new plaque vulnerability score will be established for more precise definition of the most vulnerable plaques that carry the greatest risk of rupture and subsequent detrimental clinical outcomes in the future. Such score might help in targeting these plaques with certain therapeutic interventions aiming to their stabilization.

Left main stenosis use to be treated by bypass but with the improvement of angioplasty techniques, an increasing number of patients are submit to left main coronary angioplasty. Consequences of left main intra stent stenosis can be disastrous yet, for the moment, no precise recommendation concerning the follow up of these patients exist. The investigators ought to determine if stress echocardiography can predict left main intra stent stenosis as well (non inferiorly)as control angiography that use to be done.

This is a non-randomized, non-interventional pilot observational study designed to follow high-risk patients through their surgical and hospital stay. The investigators will collect 2 4ml vial's of blood (total of 8ml) prior to surgery to assess CV biomarkers - inflammatory, metabolic, hypercoagulable and platelet.

The overall goal of this study is to determine if non-invasive imaging with state of the art CT coronary angiography can be used to screen for coronary artery disease in high risk patients prior to liver and lung transplantation. The current protocol for coronary artery disease assessment at UCSF before liver and lung transplantation involves screening with stress tests and/or coronary angiograms in patients with increased risk of coronary artery disease. Coronary angiogram will be used as gold standard for assessment of coronary CTA accuracy.
