Active clinical trials for "Myocardial Ischemia"

The hypothesis of this study is that strut coverage occurs earlier when a DES is implanted to treat a BMS restenosis compared with atherosclerotic de-novo lesion. This hypothesis is supported by two different observations: first, when a DES is implanted to treat a BMS restenosis, stent struts are deployed and drugs are eluted on a soft tissue mostly characterized by extracellular matrix with a regular surface. In this case stent malposition is less likely to occur compared to atherosclerotic lesion whose surface is often more irregular and rich in calcium. Second, patients who develop in-stent restenosis after BMS implantation are likely to show a more pronounced neointima hyperplasia and, when a DES is implanted to treat restenosis, reendothelialization is likely to occur earlier. If this hypothesis was verified, duration of dual antiplatelet therapy could be shortened after DES implantation on BMS restenosis with a clinical advantage in terms of bleeding risk. Furthermore, a higher bleeding risk is often a reason for choosing a BMS instead of a DES; thus, patients presenting with BMS restenosis are likely to have a higher bleeding risk and to benefit from a shorter period of dual antiplatelet therapy.

Monocytes may be separated into phenotypically and functionally distinct cell types by the presence or absence of the lipopolysaccharide receptor CD14 and the Fcγ-receptor CD16. The investigators hypothesize that the total numbers of CD16+ monocytes are significantly related to cardiovascular outcome in patients with angiographically proven coronary heart disease.

The purpose of this study is to compile real-world clinical outcomes data for the ION™ Paclitaxel-Eluting Platinum Chromium Coronary Stent System in routine clinical practice.

A large number of cardiac catheterizations are performed each year, primarily to diagnose heart disease. However, a cardiac catheterization is an invasive procedure which is associated with serious complications such as heart infarction, stroke, and death. Therefore, there is a need for non-invasive procedures to diagnose coronary heart disease. The purpose of this study is, therefore, to assess the diagnostic accuracy of non-invasive cardiac imaging modalities for the detection of heart disease in patients presenting for the first time to the cardiologist with chest pain.

The purpose of the study is to study if coronary angiography cause cognitive dysfunction.

The purpose of this study is to measure the percentage of women with known Coronary Artery Disease (CAD) who are hyporesponsive to low dose (81 mg) aspirin.

The purpose of this study is to evaluate CARDIAC MAGNETIC RESONANCE UTILITIES IN THE ISCHEMIC HEART DISEASE as topographical correlation between ischemic territory injury and coronary angiography.

Studies show that depression is a risk factor for the development of coronary artery disease (CAD). Furthermore there is an increased occurrence of depression in patients with CAD. Among other mechanisms atherosclerosis is believed to play a central role regarding these notable associations between depression and CAD. Moreover, patients with late onset major depression have an increased number of small lesions found in the white matter of the brain, the so-called white matter lesions. The main goal of this project is to examine if CAD is associated with depression and/or white matter lesions. CAD is evaluated using coronary CT angiography. Depression is evaluated using a semi-structured diagnostic interview. White matter lesions are quantified using cerebral magnetic resonance.

The purpose of this study is to determine whether aspirin and clopidogrel resistance measured with Multiplate function analyser has a good correlation with incidence of major adverse cardiac events in patients with coronary artery disease (CAD).

To estimate the rates of percutaneous coronary intervention (PCI) outcomes in patients after drug-eluting stents implantation who take statins.
