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...

background: left ventricular dysfunction is one of the most powerful predictors of early and late outcomes in patients who undergo coronary artery bypass grafting (cabg). the aim of this study was to assess the early results of cabg that predict 30-day mortality and prolonged length of hospital stay (los) after cabg in patients with an ejection fraction (ef) of 30% or less. methods: seven hundr...

introduction: doppler ultrasonography (dus) is the most preferable method for screening of carotid artery disease in patients undergoing cabg. the purpose of this study was to investigate the frequency of carotid artery disease and determine the relation between known risk factors of atherosclerosis and rate of carotid artery narrowing in order to identify high-risk groups among patients schedu...

background there have been many concerns about alteration in hemodynamic parameters within and shortly after endotracheal intubation (eti) in patients scheduled for elective coronary artery bypass grafting (cabg). objectives we compared the attenuation effect of magnesium sulfate and lidocaine on hemodynamic responses after eti, in patients undergoing cabg. patients and methods in this randomiz...

conclusions gargling a green tea solution, an anti-inflammatory, natural, and harmless substance, can reduce the pain of sore throat in patients after endotracheal extubation. objectives the aim of this study was to investigate the effect of green tea gargling on sore throat after coronary artery bypass grafting (cabg). patients and methods this was a single-blind, randomized clinical trial, in...

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...

OBJECTIVES To evaluate the safety and effectiveness of a self-closing surgical clip with an interrupted technique in left internal thoracic artery to left anterior descending artery bypass grafting. METHODS Eighty-two patients were enrolled and treated (February 2000 through August 2001) in a prospective, nonrandomized, multicenter trial. Left internal thoracic artery to left anterior descend...

conclusions: in the present study, applying positive airway pressure methods (cpap or imv) during cpb was associated with better postoperative abg measurements and (a-a) do2. results: the demographic data were similar in between three groups. graft number, pump time and preoperative abgs were not significantly different. postoperative pao2 were significantly higher in the cpap and imv groups an...

Relevance. Coronary artery transplantation operations are an effective method for the treatment of developmental anomalies and pathologies coronary arteries, which lead to a cascade negative consequences. Pathologically altered arteries cannot fully function normally this condition leads myocardial ischemia. Ischemic heart disease (CHD) is chronic inflammatory that quickly functional disorders ...
