Active clinical trials for "Myocardial Ischemia"

It is widely accepted that coronary artery disease (CAD) is related to a high mortality. It is predicted that an increase of approximately 21.3 million cardiovascular events and 7.7 million cardiovascular deaths over 2010 to 2030 in China.1 Male sex, diabetes mellitus, hypertension, hypercholesterolemia, obesity and smoking are all traditionally considered as risk factors for CAD. In recent decades, tremendous progress toward the prevention and treatment of traditional cardiovascular risk factors have helped decrease the morbidity and mortality from CAD, but the condition remains a major public health challenge worldwide. Looking into the other potential risk factors (OSA) for CAD, it may help to develop additional preventative strategies and further reduce the incidence and mortality of CAD.

The purposes of this study are 1) to explore the association between multi-dimension facial characteristics and the increased risk of coronary artery diseases (CAD); 2) to evaluate the diagnostic efficacy of multi-dimension appearance factors for coronary artery diseases.

Hypotension with potentially serious consequences for organ perfusion is a common complication in extracorporeal procedures such as heart-lung-machine. The exact reasons for this are still insufficiently clarified. Probably periinterventional vasorelaxant released substances play a crucial role in these procedures. These substances could be due to contact of blood cells with the Membrane in the HLM arise. In this project the hypothesis will be checked, if EETs / DHETs are released by Erythrocytes during this extracorporeal procedure and thus act as potential candidate products for the result of hypotonic phases during usage of heart-lung-machine. We will determine differences in RBC fatty acids profiling in patients before and after heart-lung-machine intervention. RBC fatty acids profiling will be achieved by using targeted HPLC-MS mass spectrometry. It is believed that during HLM there is an increase in EETs / DHETs in the serum and in the erythrocytes. It is believed that shear forces play an important role in the release of erythrocyte EETs / DHETs.

This study is planned to assess the effect of obesity (BMI over 30 kg / m2) on hospital outcomes of isolated coronary artery bypass grafting in patients with chronic ischemic heart disease.

This randomized controlled trial was conducted with 58 patients hospitalized in the cardiology clinic of a state hospital. Personal Information Form, Anthropometric measurements, Framingham risk score, and compliance questionnaire (CQ) were used to collect the data.

Cliflical evaluation of th' Orsiro LESS 10 diabetic subjects requiring coronary revasculariza t ion with Drug Eluting Stefl ts (DES) .880 subjects will be enrolled in this registry. The sample subjects size may be increased in order to reach the subgroup sizes (Small Vessel and AMI).

Antiplatelet therapy with aspirin-clopidogrel reduces the risk of cardiovascular episodes after percutaneous coronary intervention (PCI) in patients with acute coronary syndromes. However, a significant number of patients experience recurrent events while on such therapy. The individual response to dual antiplatelet therapy is not uniform, and consistent findings across multiple investigations support the association between a lower degree of platelet inhibition, high on-treatment platelet reactivity, and the occurrence of atherothrombotic events [1, 2]. Particularly in diabetic patients, clopidogrel resistance is more prevalent compared with non-diabetics [3,4], which seems to contribute to the increased atherothrombotic risk in these patients compared with those without diabetes mellitus (DM) [5]. A number of platelet function instruments have now become available that are simple to use and can be utilized as point-of-care (POC) instruments in order to monitor antiplatelet therapy and potentially assess the risk of a recurrent event [6].

Both clinical and experimental studies demonstrate the importance of the pre-existing, ie innate collateral supply in different vascular regions. Furthermore, pathophysiological considerations and experimental data imply an important role for the association of collateral function between different vascular regions. STUDY HYPOTHESES 1. In the absence of atherosclerotic stenoses, there is a direct association between the collateral function in the coronary, renal and peripheral circulation. 2. The increase in plasma renin in response to a unilateral main renal artery balloon occlusion is inversely related to its functional collateral supply. 3. The decrease in renal vein oxygen saturation in response to a unilateral main renal artery occlusion is inversely related to its functional collateral supply.

This study will compare how well a new radiolabeled imaging agent ECDG compares to the current testing for coronary artery disease (radiolabeled Sestamibi) during a rest and stress cardiac test as documented from results of a coronary angiogram (if performed).

The purpose of this study is to estimate the prevalence of allergic diseases and atopy among patients with angiographically confirmed coronary artery disease as well as to assess levels of serum allergic inflammation markers in this population.
