“…In 1 study, off-pump CABG average core temperature in the operation room was significantly higher in the patients that developed new-onset AF [36]. In another study of AF after cardiac surgery, postoperative fever was associated with troponin I levels, which on its own was not associated with postoperative AF [37].…”

Background: Several studies have associated elevated C-reactive protein (CRP) levels to the occurrence of atrial fibrillation (AF). We sought to estimate the frequency and prognostic impact of AF in patients with bacteremia, and to study the possible association between AF and CRP as well as between AF and mortality in this population. Methods: We retrospectively evaluated patient charts of patients with bacteremia with Escherichia coli or Streptococcus pneumoniae admitted to the Aker University Hospital in Oslo between 1994 and 2004. Known cardiac risk factors for AF, signs and mode of conversion of AF, and, if applicable, date of death were registered, as were characteristics of infection, such as systemic inflammatory response syndrome and white blood cell count. Initial CRP values were categorized into 4 strata. Odds ratios of the 3 highest CRP categories compared with the lowest were obtained from logistic models adjusting for known cardiac risk factors for AF as well as possible factors that may have had an impact on the odds ratios for the different CRP levels. Cox regression analysis was used to compare new-onset AF and death during the first 2 weeks after hospitalization. Results: A total of 672 patient charts were studied; 104 patients (15.4%) had new-onset AF. Peak incidence of new-onset AF occurred on the day of admission. Peak CRP values were reached during the following 2 days. High CRP level at admission did not predict the occurrence of AF. The observed mortality was higher among patients with new-onset AF (p = 0.001) during the first 2 weeks after hospitalization, but this effect disappears when adjusted for relevant factors. Conclusions: The frequency of new-onset AF in bacteremia is substantial. Initial CRP levels or white blood cell count do not seem to predict new-onset AF, as opposed to systemic inflammatory response syndrome. On the other hand, in patients with bacteremia, new-onset AF should be viewed as an indicator of increased mortality and morbidity.

Off-pump coronary artery bypass grafting (OPCAB) is performed in about 65% of patients who require surgical coronary revascularization, and has become the standard procedure in coronary artery bypass grafting (CABG) in Japan. As a background of the high rate of OPCAB, many clinical and experimental studies have been performed and reported in Japan. In this review, several factors associated with OPCAB are discussed based on relevant and important clinical studies published in Japan in the English language.

“…However, controversy still remains as to whether OPCAB can reduce the incidence of postoperative AF [2][3][4][5]. Although a recent metaanalysis showed OPCAB signifi cantly reduced the incidence of postoperative AF compared with conventional CABG [6], the incidence of postoperative AF following OPCAB has been reported to remain high, at 21%-32% [2,3,[7][8][9]. Several factors, including low ejection fraction, and cardiac arrest have been reported as predictors of postoperative AF following conventional CABG [5,[10][11][12].…”

“…Several factors, including low ejection fraction, and cardiac arrest have been reported as predictors of postoperative AF following conventional CABG [5,[10][11][12]. On the other hand, some perioperative factors have also been reported to be predictors of postoperative AF following OPCAB [7,8,13]. Biomarkers indicating the infl ammatory status of the patient, such as baseline C-reactive protein level, postoperative interleukin-6 level, and white blood cell count have been reported as independent predictors following conventional CABG and OPCAB [14,15].…”

Predictors of atrial fibrillation after off-pump coronary artery bypass graft surgery

Abstract: Our present findings indicate that ageing, the intraoperative fluid balance, and postoperative cardiac index are associated with the onset of AF after off-pump CABG.
