A longstanding empirical interest on psychosocial factors in CABG surgery patients highlights an association with increased risk of morbidity in the short and longer term. Recent evidence suggests that both depression and anxiety increase the risk for mortality and morbidity after CABG surgery independent of medical factors, although the behavioral and biological mechanisms are poorly understood. Though neither depression nor anxiety seem to markedly affect neuropsy- chological dysfunction, depression confers a risk for incident delirium. Following a comprehensive overview of recent literature, practical advice is described for clinicians taking into consideration possible screening aids to improve recognition of anxiety and depression among CABG surgery patients. An overview of contemporary interventions and randomized, controlled trials are described, along with suggestions for future CABG surgery research.展开更多

Hsp 70, IgE, MMP-9, creatine phosphokinase-MB （CPK-MB）, and lactate dehydrogenase （LDH） levels were measured in normal subjects （n = 20）, and in patients with chronic stable angina pectoris who were referred for elective CABG, before and after performing CABG-surgery （n = 20）. Compared with normal subjects, increased Hsp 70 and IgE levels, unchanged MMP-9 level, and activities of CPK-MB and LDH were found in the pre-operative patient group. Hsp 70 and IgE levels in the post-operative period were significantly reduced when compared to pre-operative period. Hsp 70 and IgE might be used as markers for detection of early minor myocardial damage, and coronary insufficiency with less overt damage than myocardial infarction, as significant changes in their levels appear before occurrence of in any changes in the levels of MMP-9, CPK-MB and LDH. Besides, Hsp 70, and IgE returning to the normal levels after CABG surgery, suggest that they could be helpful to evaluate the effect of CABG surgery.展开更多

Among them, 133 (98.5％) of 135 arterial grafts were patent, and 345 (77.7％) of 444 saphenous-vein grafts were patent. Within 5 years or between 5 and 10 years after operation, arterial graft patency exceeded venous graft patency (P ＜ 0.001 ). Three-dimensional EBT angiography achieved higher sensitivity, specificity and accuracy (97.7％, 94.1％ and 96.7％, respectively) than did EBT flow study (88.4％, 82.4％ and 85.2％, respectively) for evaluating occlusion or patency of CABG. The intra-graft flow of patent arterial and venous grafts were 4.9 ± 2.2 mi · min-1 · g-1 and 6.9 ± 2.8 mi · min-1 · g-1,respectively (P＜0.001).Conclusion The combination of EBT three-dimensional reconstruction and flow study can be more effective in the assessment of CABG anatomy and quantification of patent CABG blood flow.展开更多

In this study, these two procedures were compared for postoperative wound healing and long-term graft patency. We reviewed all consecutive patients undergoing elective off-pump coronary artery bypass grafting from January 2004 to December 2005 and collected data regarding wound complications and coronary events. Wound complications included dehiscence, excessive discharge, edema, altered sensation, cellulitis, hema-toma, pain scale, and superficial and deep wound infection. Coronary events were defined as diagnosis of myocardial infarction during the first year's follow-up. A total of 392 patients were included in our series, among whom 44 were excluded from the study due to emergent operation, preoperative intra-aortic balloon pump support, or the greater saphenous vein varicose characteristic, 78 belonged to open vein harvest group, and 270 to endoscopic vein harvest group. Wound complications were significantly less in the endoscopic group (5.2%) compared to the open group (19.2%) (P=0.0002). There was no significant difference on preopera-tive risk factors, total operative time, or hospitalization days. During one-year follow-up, both the early and late graft patency rates were similar between the two groups. Endoscopic vein harvest is safe and effective, which carries less risk for wound complica-tions and is associated with better satisfaction and cosmetic result than the traditional greater saphenous vein harvest procedure. The endoscopic vein harvest also demonstrates a great long-term patency.展开更多
