Active clinical trials for "Coronary Disease"

The main aim of this study will evaluate differences in serum levels of tryptase in study population. Will be selected a number of 350 patients hospitalized for coronary heart disease.

The aim of this study is to prospectively investigate the relationship of circulating endothelial progenitor cells at time of percutaneous coronary intervention to the subsequent development of in-stent restenosis or progression of coronary atherosclerosis.

The purpose of this study is to compare the response to aspirin in the acute phase with the late phase of an acute coronary syndrome.

The Mindfulness Intervention as Myocardial Infarction Rehabilitation Additive (MIMIRA) study aimed at studying the feasibility and acceptability of Mindfulness Based Stress Reduction - an 8 week course in meditation and yoga - in patients with a recent coronary artery event and elevated depressive symptoms. To address these questions patients with elevated scores on a depression scale were invited to participate in MBSR, and there evaluation of the course as well as a panel of psychological risk factors and resources was measured.

Coronary heart disease (CHD) poses a major health burden in the Gulf countries. It is the leading cause of mortality and morbidity in the world and poses an enormous societal burden in the Gulf countries. Early detection of disease is imperative to reduce the health care burden and financial costs associated with CHD. Knowledge of novel genetic and proteomic markers of CHD will provide more precise estimates of risk while defining the pathways important in individual patients, revealing new targets for intervention, and ultimately enabling an individualized approach to care. To translate recent advances in genomics and proteomics into clinical practice, these newly discovered biomarkers will need to be evaluated in patients of diverse ethnic groups with varying characteristics, environmental factors, and medication use. The investigators propose to establish a biorepository of plasma and Deoxyribonucleic acid (DNA) linked to demographic and clinical variables to facilitate biomarker studies of CHD risk, progression, and outcome. The overarching goal in developing the Qatar Cardiovascular Biorepository (QCBio) is to create a resource that fosters research aimed at identifying novel biochemical and genetic markers of CHD. A biorepository with linkage to clinical data will also provide an invaluable resource for cardiovascular research, including genomic and proteomic studies of CHD and development of biomarkers for early detection of disease and personalized drug therapy (pharmacogenetics and pharmacoproteomics).

Atherosclerosis is a progressive disease of the arterial wall, arising from the combination of endothelial dysfunction and inflammation. This link is exacerbated in diabetic patients. Uric acid is known to generate oxidative stress and it's elevated levels has been shown to be associated with cardiac hypertrophy, inflammation, myocardial fibrosis and diastolic dysfunction. Allopurinol inhibits xanthine oxidase, an enzyme that regulates uric acid production. In observational studies it has been shown to reduce ischemia, inflammation and improve coronary flow. The aim of this study is to see whether treatment with Allopurinol in patients diagnosed with multivessel disease and undergoing treatment with either percutaneous coronary intervention (PCI) or coronary artery bypass surgery (CABG) , will reduce markers of inflammation and improve quality of life and major adverse cardiovascular effects (MACE).

With effective anti-retroviral therapy, non-communicable diseases, such as cardiovascular diseases, have become the major cause of morbidity and mortality for people living with HIV. There is only limited data evaluating the burden and risk factors of cardiovascular disease in the Asian HIV-infected population. Accurate non-invasive tools for prediction of cardiovascular disease, particularly in Asian HIV-infected populations, are urgently needed. Recently, more detailed evaluation of the complex retinal vasculature has been made feasible with advances in digitalized retinal imaging techniques. This study aims 1. to determine the prevalence of coronary atherosclerosis and obstructive coronary artery disease HIV-infected individuals with one or more cardiovascular disease risk factors in Asia. 2. to determine the performance of automatic retinal image analysis (ARIA) in predicting the risk of coronary artery disease in HIV-infected individuals, as compared to traditional risk prediction tools. Patients will undergo a coronary CT angiogram, followed by an automatic retinal image analysis within 4 weeks post completion of CT angiogram.

Patients undergoing Open Cardiac Surgery will be randomized into two groups. Group I will be ventilated with 40% Fio2 during induction, surgery and in Postoperative care unit. Group II will be ventilated with 100% Fio2 during induction and with 60-70% ( determined according to the arterial blood gas sample results) during surgery and in Postoperative care unit. Hemodynamic parameters ( systolic arterial pressure, diastolic arterial pressure, heart rate ), Arterial blood gas samples ( PaO2, PaCO2, pH, Oxygen saturation, Lactate), and pre and post cardiopulmonary bypass Superoxide dismutase and malonyl aldehyde levels.

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.

Coronary heart disease has a high incidence and high death rate. Percutaneous coronary intervention (PCI) is an important method for the treatment of coronary heart disease (CHD). However, PCI may cause myocardial cell injury and myocardial infarction 4 Type(MI4a, Type 4 a myocardial infarction related to PCI). Dexmedetomidine(Dex) is the only anesthetic which has sedative and analgesic effects. Dex currently has been widely used in perioperative management of various surgical.This study intends to verify the effect of heart protection of Dex in perioperative.
