Active clinical trials for "Myocardial Ischemia"

1.1 To build a TCM diagnosis and treatment database for chronic stable CAD; 1.2 To summarize the pattern of TCM medicine used and the effect of the medication in chronic stable CAD. 1.3 To formulate a syndrome differentiation determined medicine plan based on the improvement in the quality of life on chronic stable CAD patients.

Mechanisms that link metabolic syndrome to atherosclerosis are incompletely understood. As a part of Hämeenlinna Metabolic Syndrome Research Program (HMS) surrogate indicators for atherosclerosis are studied in 120 men with metabolic syndrome, 120 men with coronary heart disease and 80 physically active controls and in different settings.

Optical coherence tomography (OCT) has been recently studied for evaluation of coronary stenting. Because of high resolutions, several reports have shown that OCT is appropriate for evaluating neointimal tissue after coronary stent implantation. Also, the strut coverage and the characterization of neointimal tissue can be accurately evaluated. Furthermore, OCT-defined coverage of a stent strut was proposed to be related with clinical safety in drug-eluting stents-treated patients. Therefore, the investigators will evaluate the appropriateness of currently using coronary stents (e.g. Sirolimus eluting stent, Paclitaxel-eluting stent, Zotarolimus-eluting stent, Everolimus-eluting stent, Biolimus eluting stent, EPC(endothelial progenitor cell) Capture stent, etc) based on the findings of OCT. Additionally, the investigators will evaluate neointimal hyperplasia, malposition or strut coverage to decide the differences in the stent characteristics, the duration of antiplatelet use, and the differences according to the clinical presentations.

Coronary artery calcification (CAC) is a pandemic condition in elderly patients with coronary artery disease (CAD) and associated with worse prognosis. Although available data shows association between testosterone levels in men and CAD, the association between testosterone and CAC in old-aged male patients with CAD remains unknown. In this study, the relationship of serum testosterone levels with CAC score in elderly male patients with CAD was evaluated.

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.

The main objective of the GENOCOR project (Genetic mapping for cardiac risk assessment) is the setting up of a joint public/private laboratory (GENOCOR-LAB) dedicated to the development and testing of new cost-effective technologies exploiting the growing knowledge in the genomic correlates of cardiovascular diseases (CVD) and of their evolution; the data obtained by the GENOCOR-Lab should especially orient secondary prevention and specific treatment of ischemic heart diseases (IHD).

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).

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.

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.
