Background : Quests for doing coronary artery bypass surgery by a technique with lower complications is going on, for this aim many studies compared patients undergoing CABG with or without cardiopulmonary bypass. This study was carried out to compare laboratory findings after coronary artery bypass in these two groups of patients. Materials and Methods: In a retrospective study, 167 patients ...

OBJECTIVE Off-pump coronary artery bypass grafting may result in fewer myocardial and vascular complications than on-pump. Although differences in aortic manipulations likely play a role, the systemic responses of endothelial progenitor cells to both types of operations have not been examined. We sought to examine endothelial progenitor cell characteristics after off-pump versus on-pump coronar...

The Effect of Open Lung Ventilation on Respiratory Mechanics, Postoperative Organ Function, and Inflammatory Mediators in Coronary Artery Bypass Surgery

background: currently healthy heart word considered to be the objective of community health applications in many countries of the world because cardiovascular diseases are the most important factor in mortality of humans, worldwide. coronary artery bypass graft surgery is one of the most common surgery procedures for these patients. the purpose of this study is to assess the impact of therapeut...

OBJECTIVE To compare the clinical, angiographic, neurocognitive, and quality of life outcomes of off-pump coronary artery bypass surgery with conventional coronary artery bypass grafting surgery using cardiopulmonary bypass. DESIGN Randomised controlled clinical trial. SETTING Tertiary cardiothoracic centre in Middlesex, England. PARTICIPANTS 168 patients (27 women) requiring primary isol...

The most quoted long-term outcome studies from the coronary artery bypass surgery literature were performed in the 1970s, and these trials--the Coronary Artery Surgery Study, the Veterans Administration Study, and the European Cooperative Study--added significantly to our knowledge of the efficacy of bypass surgery. However, important studies are still being performed and are refining our knowl...

OBJECTIVES Patients with coronary artery disease and left ventricular dysfunction have high mortality when kept in clinical treatment. Coronary artery bypass grafting can improve survival and the quality of life. Recently, revascularization without cardiopulmonary bypass has been presented as a viable alternative. The aim of this study is to compare patients with left ventricular ejection fract...

A mechanical model of a branched coronary artery with a graft bypassing an 80% stenosis of one branch was used to study the reduction in coronary flow due to stenosis of the bypass graft. Flow Reynolds number and ratio of aortic pressure to dynamic pressure were matched to the living system. Changes in coronary flow were measured for a range of stenoses (0-100%) of bypass grafts with graft-to-c...
