Outcomes of "off-pump" coronary artery bypass grafting in a developing country : advantages over coronary artery bypass grafting on cardiopulmonary bypass
Off-pump coronary artery bypass grafting (OPCAB) was developed to avoid the deleterious effects of CPB. Current literature reveals some peri-operative advantages of OPCAB, with few studies detailing these in Africa. We review our institutional experience with both approaches in higher risk patients …

The effects of preconditioning coronary artery disease patients with hyperbaric oxygen prior to coronary artery bypass graft surgery & cardiopulmonary bypass
IntroductionCoronary artery bypass graft (CABG) is associated with periods of ischaemia and reperfusion, which may lead to myocardial dysfunction. In clinical studies, hyperbaric oxygen (HBO2) treatment following an acute myocardial infarction (AMI), has been shown to limit myocardial injury and …

Endothelialization of Bypass Grafts Using Autologous Stem Cells
… of death in the United States. Coronary artery bypass grafting (CABG) is the standard of care but may be limited by the availability of suitable autologous grafts. Despite synthetic substitutes showing success in large-diameter bypass grafts, they are not suitable for replacing small-diameter …

Predicting fan noise propagation in aeroengine bypass ducts
… of rearwards fan noise propagation within the bypass duct and its radiation into the far feld. Two recently developed models: B-induct and GXMunt, are exploited in application to real engine bypass ducts and their performance is evaluated. These methods are an improvement on current industry …

Epidural analgesia for coronary artery bypass graft surgery
On reviewing the medical literature, there is a clear resurgence of interest in the use of TEA (thoracic epidural analgesic) in cardiac anaesthesia. This resurgence was brought about by laboratory-based evidence that TEA-induced sympatholysis may be cardioprotective through the promotion of …

Functional Capacity Outcomes following Coronary Artery Bypass Graft Surgery
The objective of this study was to determine if this is possible to predict 3 mo post-CABG treadmill VO2pk outcomes from a combination of pre-surgical physical fitness and health and clinical status variables. To determine the VO2pk, subjects performed a maximal treadmill test using a ramp protocol …
