Abstract:
Objective: To explore the risk factors in patients with chronic heart failure (CHF) combining atrial ifbrillation (AF) and to identify the predictive factors for AF recurrence after cardio version. Methods: A total of 246 CHF patients treated in our hospital were divided into 2 groups: CHF+AF (AF) group,n=71 and CHF without AF (Non-AF) group,n=175. The baseline information was recorded. The risk factors for AF occurrence were screened by Logistic regression analysis. There were 66 AF patients with successful cardio verse and they were followed-up for 18 months, the predictors for AF recurrence were studied by Cox regression analysis. Results: The baseline information showed that age, CHF duration, left atria diameter (LAD), the levels of BNP, uric acid and serum creatinine in AF group were all higher than those in Non-AF group, allP<0.05. Logistic regression analysis presented that age (RR=1.89, 95% CI 1.08-3.31,P<0.05), CHF duration (RR=1.35, 95% CI 1.05-1.74,P<0.05), BNP level (RR=1.82, 95% CI 1.30-2.53,P<0.01), LAD (RR=1.51, 95% CI 1.09-2.08,P<0.05) were the risk factors for AF occurrence. Cox regression analysis indicated that BNP level (RR=1.30, 95% CI 1.09-1.54,P<0.01) and LAD (RR=1.74, 95% CI 1.30-2.34, P<0.01) were the predictors for AF recurrence. Conclusion: The elder age, longer CHF duration, increased BNP level and LAD were the risk factors for AF occurrence in CHF patients. The increased BNP level and LAD were the objective predictors for AF recurrence after cardio version.
