Active clinical trials for "Coronary Artery Disease"

China patients in end stage renal disease receiving maintenance dialysis have a high risk of cardiovascular disease (CVD), with a prevalence of 45.5% approximately, and coronary artery disease (CAD) has been identified as the most common one. It remains unclear that what their treatment status is and whether this group of patients can benefit from revascularization in China. The investigators plan to recruit around 30 hospitals from 7 regions as study centers, which represent different levels of economic development in Mainland China. The detailed information includes demographics, medical history, coronary angiogram, in-hospital treatment and procedures, short-term and long-term outcomes. The aim of the study is to provide the real world knowledge about current status of coronary revascularization and prognosis in patients with CAD and dialysis.

Basic studies has showed that sustained use of nitrates might associated with adverse effects on vascular function mediated by an increase in nitrate-induced oxidative stress. But it remains unclear whether oxidative stress increases with endothelial function impairment in patients with coronary artery disease (CAD) during administration of long-term oral nitrates. The investigators evaluated whether administration of long-term isosorbide mononitrate (ISMN) treatment was associated with oxidative stress increase and endothelial function impairment in patients with CAD.

The goal of this study is to assess the long-term efficacy and safety of Firebird2 Cobalt-Chromium（CoCr）-alloyed sirolimus-eluting stent in treatment of complex lesions in diabetes.

The negative effect of internal mammary harvesting on sternal perfusion is well known, especially in diabetic subjects. Microdialysis previously showed increased lactate tissue concentration after mammary artery preparation. Although high antibiotic concentration is of utmost importance in this region, no study previously measured the effect of internal mammary artery harvesting on target tissue antibiotic concentration. Study hypothesis: Internal mammary artery harvesting imposes an additional risk for deep sternal wound infection by impairing antibiotic tissue penetration. This effect is mediated by altered perfusion patterns and may be seen in cephalosporin and/or Teicoplanin treatment. Study objective: To evaluate the impact of left internal mammary artery preparation on target tissue antibiotic concentration of Cefazolin and Teicoplanin during cardiac surgery Design: This study is designed as an observational pharmacokinetic trial. Patients are their own controls by measuring antibiotic concentration in different subcutaneous tissues. Study population: Patients referred for coronary artery bypass grafting to the Department of Cardiothoracic Surgery with planned unilateral left internal mammary artery preparation and a high risk profile for deep sternal wound infections will be asked to participate in this trial.

The purpose of this study is to test whether cardiac autonomic dysfunction predicts is a prognostic marker in type-2 diabetics with ischemic heart disease

Atherosclerotic coronary heart disease is a condition thought to involve low-grade inflammation. Several reports, clinical and epidemiological, have demonstrated that intake of fish oil may be beneficial in attenuating the inflammatory process. Still, however, there are lacking data in respect to whether differences in composition of various marine oils may influence the inflammatory status differently. The hypothesis of the current study is that extract from the antarctic krill (Euphausia superba) is better than traditional fish oils when compared head-to-head with balanced composition of omega 3 content on inflammatory status.

Blood samples and health information (e.g., age at diagnosis, test results) are collected for the purposes of genetic research. The blood samples are assigned a number and stored in a repository for safe keeping until they are needed for a research project. Participants are persons who are healthy (not having high blood pressure, diabetes, or high cholesterol levels) or persons who have Coronary Artery Disease (CAD) and live in Indiana. Participants complete a questionnaire at the time the blood sample is drawn and are contacted once a year to update their health history. Researchers apply to the Fairbanks Institute for use of the blood samples and health information minus participant names and contact information. Their research is required to be related to find genes or substances made by genes that may be involved in Coronary Artery Disease with the purpose of improving the investigators understanding of the illness potentially leading to the development of new diagnostic tools for identifying the illness, new treatments,or preventative measures. This study will be repeated for other disorders like Diabetes and Cancer.

Construction of coronary heart disease cohort of more than 10000 patients in China. Investigation on current situation of secondary prevention of CHD will be carried out and the effect of physician training and patient education will be evaluated.

The purpose of the study is to determine whether the excretion of renal water- and salt-channels in the urine reflects the handling of water and salt in the kidneys, and whether the excretion can be used to monitor and/or predict the effects of treatment of certain heart or lung diseases.

The progressive aging of the general population cause increase in number of extensive and long surgeries in older patients. Age is a risk factor for perioperative myocardial ischemia and Postoperative Cognitive Dysfunction (POCD) The suggested study will deal with the above-mentioned complication in patients older then 65 years undergoing major non-cardiac surgeries. It has been shown that Isoflurane and sevoflurane may have a cardio-protective effect after cardiac surgery involving cardio-pulmonary bypass, and it was recommended that isoflurane should be used in these cases. A question was raised but haven't been answered yet, whether this cardio-protective effect exists also in non-cardiac major surgery. The aim of this study is to evaluate whether there is a difference in the occurrence of postoperative cognitive dysfunction and perioperative myocardial ischemia between total intravenous anesthesia using propofol and isoflurane based anesthesia.
