Methods This study group included 70 consecutive patients scheduled for elective off-pump CABG. The patients with ejection fraction （EF） less than 0. 30, history of AF, use of class Ⅰ or Ⅲ antiarrhythmic drug, implanted pacemaker, postoperative myocardial infarction or chest reopening for pericardial tamponade were excluded. Preoperative and postoperative serum NT-proBNP levels were measured by radioimmunoassay technique. Results Postoperative AF occurred in 15 patients （21.4%）; these patients had significantly higher median NT-proBNP levels when compared with those without AF after the operation （ P 〈 0. 01 ）. Using multivariate logistic regression analyses, an increase in NT-proBNP level after CABG was found to be independently associated with AF （ OR = 3.78, 95% IC = 1.81 - 4. 89, P 〈 0. 01 ）. Increased age, diabetes mellitus, preoperative use of β-blocker, proximal right coronary artery involvement, and longer operation time were al- so associated with AF. Conclusions These results indicated that AF was associated with higher NT-proBNP concentrations after off pump CABG; the increase in NT-proBNP after CABG may play an important role in the occurrence of AF after the operation. The further studies are needed to define the reason that lead to higher NT-proBNP concentrations among the patients who present AF after off pump CABG.展开更多

We sought to investigate whether the CHA2DS2-VASc score predicts stroke and death in Chinese patients with sick sinus syndrome （SSS） after pacemaker implantation and to evaluate whether the predictive power of the CHA2DS2-VASc score could be improved by combining it with left atrial diameter （LAD） and amino-terminal pro-brain natriuretic peptide （NT-proBNP）. Methods： A total of 481 consecutive patients with SSS who underwent pacemaker implantation from January 2004 to December 2014 in our department were included. The CHA2DS2-VASc scores were retrospectively calculated according to the hospital medical records before pacemaker implantation. The outcome data （stroke and death） were collected by pacemaker follow-up visits and telephonic follow-up until December 3 l, 2015. Results： During 2151 person-years of follow-up, 46 patients （9.6%） suffered stroke and 52 （10.8%） died. The CHA2DS2-VASc score showed a significant association with the development of stroke （hazard ratio [HR] 1.45, 95% confidence interval [CI] 1.20-1.75, P 〈 0.00 1） and death （HR 1.45, 95% CI 1.22-1.71, P 〈 0.001）. The combination of increased LAD and the CHA2DS2-VASc score improved the predictive power for stroke （C-stat 0.69, 95% CI 0.61-4）.77 vs. C-stat 0.66, 95% CI 0.57-0.74, P = 0.013）, and the combination of increased NT-proBNP and the CHA2DS2-VASc score improved the predictive power for death （C-stat 0.70, 95% CI 0.64-0.77 vs. C-stat 0.67, 95% CI 0.60--0.75, P= 0.023）. Conclusions： CHA2DS2-VASc score is valuable for predicting stroke and death risk in patients with SSS after pacemaker implantation. The addition of LAD and NT-proBNP to the CHA2DS2-VASc score improved its predictive power for stroke and death, respectively, in this patient cohort. Future prospective studies are warranted to validate the benefit of adding LAD and NT-proBNP to the CHA2DS2-VASc score for predicting stroke and death risk in non-AF populations.展开更多
