Preconditioning by isoflurane as a volatile anesthetic in elective coronary artery bypass surgery.

Background: Some pharmacological preconditioning approaches are utilized as an effective adjunct to myocardial protection, particularly following cardiac procedures. The current study addressed the potential clinical implications and protective effects of isoflurane as an anesthetic most applicable on postoperative myocardial function measured by cardiac biomarkers.

Methods: 46 patients were included in the study.

Evaluation of accuracy of Euroscore risk model in prediction of perioperative mortality after coronary bypass graft surgery in Isfahan.

Background: This study aimed to evaluate the accuracy of Euroscore (European System for Cardiac Operative Risk Evaluation) in predicting perioperative mortality after cardiac surgery in Iranian patient population.

Methods: Data on 1362 patients undergoing coronary bypass graft surgery (CABG) from 2007 to 2009 were collected. Calibration was assessed by Hosmer-Lemeshow goodness-of-fit.

Influence of the timing of cardiac catheterization and amount of contrast media on acute renal failure after cardiac surgery.

Background: There is limited data about the influence of timing of cardiac surgery in relation to diagnostic angiography and/or the impact of the amount of contrast media used during angiography on the occurance of acute renal failure (ARF). Therefore, in the present study the effect of the time interval between diagnostic angiography and cardiac surgery and also the amount of contrast media used during the diagnostic procedure on the incidence of ARF after cardiac surgery was investigated.

Methods: Data of 1177 patients who underwent different types of cardiac surgeries after cardiac catheterization were prospectively examined.
