Active clinical trials for "Myocardial Ischemia"

The purpose of the study is to evaluate the effectiveness of the CADence system, a non-invasive device, in detecting greater than or equal to 50% coronary stenosis anywhere in the coronary tree.

Patients with coronary artery disease (CAD) are often treated with dual antiplatelet therapy (DAT), including aspirin and clopidogrel, to prevent from recurrent atherothrombotic events. Levels of platelet reactivity in patients on DAT can be influenced by concomitant treatment with medications that inhibit the CYP3A4 system involved in the activation of clopidogrel. Atorvastatin and simvastatin are metabolized by CYP3A4 [Clin pharmacokinetic 2002; 41: 343-70], whereas the cytochrome P450 mediated metabolism of rosuvastatin appears to be minimal and principally mediated by the 2C9 isoenzyme, with little involvement of CYP3A4 [Clin Ther 2003; 25: 2822-5.]. Previous studies comparing atorvastatin versus rosuvastatin by means of ex vivo platelet function tests have yielded conflicting results.

This registry is a clinical post-market evaluation of the Orsiro LESS in subjects requiring coronary revascularization with Drug Eluting Stents (DES).

Compared with conventional treatment of the coronary heart disease,the aim of the research is to find out if the addition of Yangxinshi pills on the basis of conventional treatment can improve exercise tolerance of patients with coronary heart disease, improve quality of life or restore social function and mental health

It is known that laughter can bring benefits in terms of physiological and psychological parameters, in addition to improving the individual's quality of life. However, the literature is still scarce as to the existence of studies investigating the effects of a comedy film specifically in hemodynamics.

In our clinical controlled trial, patients with coronary heart disease will be randomly assigned into the exercise intervention (low intensity resistance training with vascular occlusion) or usual physical activity group (control group).

Intro: Chronic total occlusions (CTO) are the most severe coronary lesions. Negative distal vessel remodeling occurs in these lesions, leading to reduction of artery diameter. Treatment of CTO with percutaneous coronary intervention (PCI) is associated with good clinical outcomes. However, QCA and IVUS studies showed a notable lumen and vessel enlargement distal to recanalized CTO. In addition, optical tomography (OCT) studies showed high rates of stent strut malapposition and incomplete stent strut coverage after CTO PCI. The Stentys Xposition S is a self-apposing stent device which lowers stent strut malapposition rates. Its safety and effectiveness has been demonstrated in STEMI and stable coronary patients but never investigated in CTO lesions. Hypothesis/Objective To investigate whether self-expanding stents are more effective than balloon-expandable stents for reducing stent malapposition at 6 months after implantation in patients with CTO undergoing percutaneous coronary intervention. Method Pilot randomized study. Patients are randomized to receive either self-expandable stent or balloon expandable stent to perform CTO-PCI. Follow-up coronary angiography is performed at 6 months post-PCI. Stent malapposition is evaluated by OCT.

This study aims to evaluate the efficacy and safety of traditional Chinese medicine DaZhu Rhodiola Rosea Capsule for treatment of coronary artery disease by observing angina symptoms, exercise capacity, and quality of life.

Cardiovascular disease (CVD) is a group of diseases including both the heart and blood vessels, thereby including coronary heart disease (CHD). To date, diabetics have a higher incidence and prevalence of multivessels CHD. Treatments in multivessels CHD in diabetics include full medical anti ischemic therapy, and revascularization therapy (Percutaneous coronary intervention (PCI) and/or Coronary artery bypass grafting (CABG)). Randomized trials comparing multivessel PCI to CABG have consistently demonstrated the superiority of CABG in reducing mortality, myocardial infarctions and need for repeat revascularizations. After the CABG treatment, diabetics vs. non-diabetics evidenced a worse prognosis, and an increased mortality. Numerous molecular, epigenetics (as microRNAs), and other metabolic risk factors may condition the worse prognosis in diabetics vs. non diabetics after CABG. In this context, an increased epicardial fat tissue thickness may be independently associated with the prevalence of diabetes, and diabetics have an higher epicardial fat tissue thickness, volumetry, and enhanced metabolism. Therefore, after CABG, lifestyle and medical improvements may lead to the reduction of epicardial fat thickness, extension, and metabolism in both non-diabetics, and diabetics, ameliorating the prognosis. At moment, epicardial tissue function in diabetics is not well investigated in literature, and no data has been reported about new hypoglycemic drugs, and its pleiotropic effects on diabetics after CABG. Indeed, our study hypothesis was that, epicardial fat tissue dimension, and metabolic activity may be related to a different expression of inflammatory, oxidative, and apoptotics molecules, and epigenetic effectors in diabetics vs. non-diabetics. Secondary, these effectors, and epicardial tissue dimension and activity, may be controlled, after CABG, by incretin treatment in diabetics. Therefore, incretin therapy may be associated to the reduction in epicardial fat tissue thickness, and extension, with down regulation of different inflammatory, oxidative and apoptotics molecules, and epigenetic effectors involved in epicardial fat metabolism. Moreover, in this study authors will evaluate in diabetics vs. non diabetics, and in diabetic incretin-users vs. never.-incretin-users, all cause mortality, cardiac mortality, and Major adverse cardiac events (MACE) after CABG in diabetics vs. non diabetics, and diabetic incretin-users (6 months of incretin therapy) vs. diabetic never-incretin-users. Authors will correlate these clinical endpoints to the study of the epicardial fat anatomy and metabolism before and after CABG, and to circulating inflammatory and pro-apoptotic markers, epigenetic effectors, and stem cells in diabetics vs. non diabetics, and diabetic incretin-users (6 months of incretin therapy) vs. diabetic never-incretin-users.

The aim of this study is to explore the effect of newly added SGLT2I medication or placebo, to standard medication regimen in diabetic patients with documented stable coronary disease. Therefore, in the present study the investigators plan to focus on possible anti-inflammatory and athero-thrombotic protective effects of Dapagliflozin compared to placebo, in secondary prevention population of stable coronary patients with diabetes. Additionally, the investigators will explore NT proBNP dynamics, which related to ventricular filling pressures in this specific population.
