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...

background: lactic acidosis in cardiac surgical patients is a manifestation of systemic inflammation and excess pro-inflammatory cytokine production. this investigation was designed to integrate basic concepts about lactate acidosis with a clinically used of serum lactate in patients under coronary artery bypass surgery (cabg) by on pump method. methods: from august to september 2012, 15 patien...

background following coronary artery bypass graft (cabg), patients are at high risk (3.2%-8.3%) for developing hospital-acquired pneumonia (hap) with mortality rate of 24% to 50%. some of routine features in patients undergoing cabg are similar to clinical criteria of center of disease control (cdc) for diagnosis of pneumonia. this may lead to over-diagnosis of pneumonia in these patients. obje...

conclusions selenium can alleviate i/r injury in short time. further well-planned trials are needed to find the optimized administration method to achieve the most beneficial effects to the patients. background in patients with coronary artery stenosis, coronary artery bypass graft surgery (cabg) is the most effective strategy to limit infarct size and improving outcomes. however, the rapid res...

conclusions music therapy is effective in decreasing anxiety among patients undergoing cabg. however, the intervention was not effective on cardiovascular indices. music can effectively be used as a non-pharmacological method to manage anxiety after cabg. results compared to the immediately before intervention, the mean anxiety scores immediately after and 30 minutes after the intervention were...

background: coronary artery bypass graft (cabg) surgery is very traumatic and makes patients very nervous. since it is a main task of nurses to improve patients' comfort and safety, this study investigated the effect of therapeutic touch in cardiovascular patients' anxiety before cabg surgery. methods: in a controlled clinical trail study the simple random sampling was used to select 44 patient...

acute respiratory distress syndrome (ards) is a potential complication of cardiac surgery, given that patients undergoing cabg frequently have hypoxemia and pulmonary dysfunction during initial hours after surgery. thus, ards criteria in these patients are more likely to be positive while these criteria may not match the patient`s clinical picture. we aimed to investigate frequency of rapid ons...
