In this study the focus will be on correlating the levels of platelet activation markers (proteins that are released when blood cells are activated)to the duration of cardiopulmonary bypass, temperature during cardiopulmonary bypass and the weight of the patient.
It has been an established fact that cardiopulmonary bypass causes dysfunction in platelets. Activation of platelets during cardiopulmonary bypass is implicated as being a major factor in causing platelet dysfunction.
For all participants, approximately 3.15 ml of blood will be collected in special tubes called CTAD tubes, before and after cardiopulmonary bypass (6.30ml in total). This amount of blood draw is well within the guidelines of NIH (National Institute of Health).
Enzyme-linked immunosorbent assay (ELISA) will be performed using this plasma to make quantitative assessment of Platelet factor 4 and Transforming growth factor beta.

The overall goal of this study is to determine if non-invasive imaging with state of the art CT coronary angiography can be used to screen for coronary artery disease in high risk patients...
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 determine whether coronary artery CT scanning or nuclear stress testing is better at diagnosing chest pain patients with known coronary artery disease to se...
The purpose of this study is to examine the hypothesis that the presence of complex coronary lesions is associated with endothelial dysfunction, the investigators investigated whether fing...
Cardiovascular disease (CVD) is the major cause of mortality worldwide. Coronary artery disease (CAD) contributes to half of mortalities caused by CVD. The mainstay of management of CAD is medical the...
Long-term patient and kidney survival after coronary artery bypass grafting, percutaneous coronary intervention, or medical therapy for patients with chronic kidney disease: a propensity-matched cohort study.
Revascularization in patients with chronic kidney disease (CKD) and coronary artery disease (CAD) is often deferred because of concern over progression of renal failure.
To assess sex-specific differences regarding use of conventional risks and coronary artery calcification (CAC) to detect coronary artery disease (CAD) using coronary CT angiography (CCTA).
Endothelial dysfunction and coronary artery calcification (CAC) may represent two distinct and separate processes in the development of coronary atherosclerosis. However, the interaction between these...
The analytical paper summarized the results of recent studies of an association of depression, anxiety, and stress with coronary heart disease (CHD). Mental disorders are shown to be associated with i...
Abnormal balloon- or sac-like dilatation in the wall of CORONARY VESSELS. Most coronary aneurysms are due to CORONARY ATHEROSCLEROSIS, and the rest are due to inflammatory diseases, such as KAWASAKI DISEASE.
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.
Malformations of CORONARY VESSELS, either arteries or veins. Included are anomalous origins of coronary arteries; ARTERIOVENOUS FISTULA; CORONARY ANEURYSM; MYOCARDIAL BRIDGING; and others.
Pathological processes of CORONARY ARTERIES that may derive from a congenital abnormality, atherosclerotic, or non-atherosclerotic cause.
An imbalance between myocardial functional requirements and the capacity of the CORONARY VESSELS to supply sufficient blood flow. It is a form of MYOCARDIAL ISCHEMIA (insufficient blood supply to the heart muscle) caused by a decreased capacity of the coronary vessels.
