global myocardial ischemia and ischemia-reperfusion injury are potential adverse events related with cardioplegic arrest. beating heart surgery has avoided such complications and adapted to valve surgery following successful results published on myocardial revascularization. difficulty in weaning from cardiopulmonary bypass may be lessened by using on-pump beating heart surgery for mitral valve...

background: the prevalence of patients with severe left ventricular dysfunction (lvd) referred for coronary artery bypass grafting (cabg) is increasing. preoperative lvd is an established risk factor for early and late mortality after revascularization. the aim of the present study was to assess the early outcome of patients with severe lvd undergoing cabg. methods: between december 2012 and no...

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...

the duration of icu (intensive care unit) stay in cardiac surgery patients has an important role in the rate of complications and costs. the aim of this study was to determine the role of perioperative risk factors in clinical outcome based on the time of icu discharge. in this descriptive study, 219 patients undergoing off-pump coronary artery bypass (opcab) surgery in afshar hospital in yazd,...

this study evaluates the effect of preoperative increased level of serum creatinine (cr) on early outcomes after coronary artery bypass graft surgery (cabg). 1140 patients who underwent cabg in our center were studied. patients with cr >2.25 mg/dl or preoperative dialysis and who had off-pump operations were excluded. group 1 consisted of 892 patients with normal cr (0.5-1.2 mg/dl) and group 2 ...

background: strengthening exercises are not favored in the rehabilitation of patients after coronary artery bypass grafts (cabg) for concerns over potential adverse effects. however, patients often present with weakened skeletal muscles post cabg due to disuse. methods: we studied the effects of aerobic and strengthening exercises on the serum c-reactive protein (crp) levels and blood pressure ...

background: new-onset atrial fibrillation (af) after cardiac surgery contributes to increased morbidity, hospital length of stay, and resource utilization. although many aspects of af after cardiac surgery have already been elucidated, the mechanism by which cardiac surgery predisposes patients to af has hitherto remained unknown. recent evidence supports the notion that blood transfusion enhan...

abstract background: right ventricular myocardial performance index (rvmpi) is a doppler–derived parameter of non-geometrical ventricular function that measures both systolic and diastolic functions of the right ventricle. the aim of this study is to compare prognostic value of rvmpi with global rv function in patients undergoing coronary artery bypass graft (cabg). methods: in a longitudinal s...

introduction: left ventricular ejection fraction (lvef) is considered to be the single most important prognostic factor in patients with previous myocardial infarction. lvef is not improved in all patients after coronary artery bypass grafting (cabg). this study aimed to assess the possibility of prediction of lvef changes after cabg using myocardial perfusion gated signle photon emission compu...

patients and methods this blinded clinical trial was performed on 60 patients admitted to icu following cabg. patients intubated and those under mechanical ventilation were unable to report their pain. the study population was randomly divided into two groups of control and music intervention groups (preferred music listening). in the intervention group, preferred music (including classical, in...
