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...

BACKGROUND The benefits of off-pump coronary artery bypass graft (OPCAB) compared with conventional on-pump coronary artery bypass graft (CCAB) remain controversial. Thus, it is important to investigate which patient subgroups may benefit the most from OPCAB rather than CCAB. METHODS AND RESULTS Among the patients undergoing first coronary revascularization enrolled in the CREDO-Kyoto Registr...

BACKGROUND It has been previously shown that a persistent (up to 1 month) prothrombotic status occurs after coronary bypass surgery performed both on pump and off pump. To assess the pathways involved in the occurrence of postoperative prothrombotic state, in this study we evaluated plasma, monocyte-bound, and platelet-bound tissue factor expression, as well as platelet and soluble P-selectin e...

Relationship Between Serum CRP Levels and Mortality; one Year After Coronary Artery Bypass Graft Surgery

OBJECTIVE Off-pump coronary artery bypass graft surgery is common therapy to completely revascularize diseased hearts. In order to graft posterior arteries in this procedure, the heart must be lifted from the chest cavity and manipulated to expose the surgical field using an apical suction device. This suction device may cause unwanted myocardial ischemia. METHODS In this observational study,...

The presence of occlusive disease of the subclavian artery (SCA) proximal to the origin of the internal thoracic artery (ITA) influences the operative strategy and the outcome of coronary artery bypass grafting (CABG). Of 780 patients who underwent CABG, concomitant SCA occlusive lesions were reconstructed in 13 patients (nine males, four females). The affected SCAs were left-sided in 11 patien...

Patients with coronary artery disease and left ventricular dysfunction have high mortality with non surgical (medical) treatment. Coronary artery bypass grafting improves survival and the quality of life. Recently, revascularization without cardiopulmonary bypass has been presented as a viable alternative. The aim of this study was to survey the result of coronary artery bypass grafting with of...

in this theoretical study, the effect of various types of bypass graft angles on the flow field, has been investigated specially on the temporal wall shear stress (wss) on the toe, heel and some locations on the bed of the left anterior descending (lad) artery at the anastomoses areas in the aorto-coronary (ac) and coronary-coronary (cc) bypasses. flow fields in both bypasses with angles of 20º...
