Coenzyme Q10 (Ubiquinone) is recognized as an endogenous fat-soluble antioxidant in the mitochondrial membrane and considered as a preventive factor for coronary artery disease (CAD). However, the relationships between coenzyme Q10 and the prevention of the risk of CAD are still inconsistent. The purposes of this study are to investigate the relation of coenzyme Q10 concentration with the blood lipid levels, plasma homocysteine, the markers of lipid peroxidation (TBARS, ox-LDL),antioxidant enzymes activities (catalase, glutathione peroxidase, superoxide dismutase)and to examine the association with the risk of CAD.The CAD patients is identified by cardiac catheterization as having at least 50% stenosis of one major coronary artery (n = 100). The second year is a double-blind, placebo-controlled intervention study. CAD subjects (n = 60) are randomly assign to one of the three groups (coenzyme Q10 supplements 60 mg/d, 150 mg/d, and placebo groups, n = 20/group). Intervention is going to administration for three months. The third year is a case-control study. The control group （n = 100） is comprised of healthy individuals with normal blood biochemical values, and match by age and gender with the first year CAD subjects (case group). Fasting blood samples will be obtain to determine the concentration of coenzyme Q10, homocysteine, the markers of lipid peroxidation,antioxidant enzymes activities. The differences between case and control groups will be compared by using Student's t-test. Conditional logistical regression model will be performed to calculate the odds ratio for CAD based on coenzyme Q10 level. Hopefully, the results of this study could provide the information to what has been know in CAD subjects. We expect coenzyme Q10 could be a preventive supplement to reduce the risk of CAD.

This study was designed to evaluate the symptomatic effects of Coenzyme Q10 nanodispersed solution in middle-stage Parkinson's disease (PD) patients (Hoehn&Yahr II to III). The treatment p...
It would be useful to study coronary arteriovenous difference of various markers in patients who are undergoing coronary angiography for suspected coronary artery disease. Environmental an...
The study will assess the change in coronary atherosclerotic disease as determined by intravascular ultrasound (IVUS) for aliskiren compared to placebo when given in addition to standard t...
Coronary artery disease is the leading cause of death in USA. Contemporary cardiac care has substantially reduced mortality and morbidity in patients with severe coronary artery disease. H...
The purpose of this study is to compare the effects of varying dosage of coenzyme Q10 (CoQ10) versus a placebo in the treatment of Parkinson's disease (PD) in patients with early, untreate...
Coronary revascularization for coronary artery disease dates to the introduction of coronary bypass surgery by Favaloro in 1967 and coronary angioplasty by Gruentzig in 1977 and first published in 196...
Comparative outcomes of coronary-artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) for left main coronary artery (LMCA) disease were previously reported. However, data on very...
A wider angle between the left anterior descending coronary artery (LAD) and left circumflex coronary artery (LCX) has been suggested to induce plaque formation in the arterial system via changes in s...
Coronary computed tomography angiography (CTA) has emerged as a non-invasive diagnostic method for patients with suspected coronary artery disease, but its usefulness in patients with complex coronary...
Gut microbiota dysbiosis has been considered to be an important risk factor that contributes to coronary artery disease, but limited evidence is known about the involvement of gut microbiota in the di...
Surgical therapy of ischemic coronary artery disease achieved by grafting a section of saphenous vein, internal mammary artery, or other substitute between the aorta and the obstructed coronary artery distal to the obstructive lesion.
Direct myocardial revascularization in which the internal mammary artery is anastomosed to the right coronary artery, circumflex artery, or anterior descending coronary artery. The internal mammary artery is the most frequent choice, especially for a single graft, for coronary artery bypass surgery.
A complication of INTERNAL MAMMARY-CORONARY ARTERY ANASTOMOSIS whereby an occlusion or stenosis of the proximal SUBCLAVIAN ARTERY causes a reversal of the blood flow away from the CORONARY CIRCULATION, through the grafted INTERNAL MAMMARY ARTERY (internal thoracic artery), and back to the distal subclavian distribution.
A congenital coronary vessel anomaly in which the left main CORONARY ARTERY originates from the PULMONARY ARTERY instead of from AORTA. The congenital heart defect typically results in coronary artery FISTULA; LEFT-SIDED HEART FAILURE and MITRAL VALVE INSUFFICIENCY during the first months of life.
Pathological processes of CORONARY ARTERIES that may derive from a congenital abnormality, atherosclerotic, or non-atherosclerotic cause.
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
