Abstract：Objective To discuss the risk factors and influence on prognosis of chronic heart failure(CHF)complicated by arrhythmia.Methods CHF patients(n=100)were retrospectively analyzed in Beijing Rehabilitation Hospital from Jan.2022 to May.2024.All patients were divided,according to status of CHF complicated by arrhythmia,into CHF+arrhythmia group(n=38)and non-arrhythmia group(n=62).The risk factors for CHF complicated by arrhythmia and relationship among them and prognosis were analyzed.Results The results of single-factor analysis showed that the differences in gender,age,smoking history,hypertension history,systolic blood pressure(SBP),diastolic blood pressure(DBP),heart rate,classification of heart function,HF cause,serum potassium,right atrial diameter(RAD)had no statistical significance between 2 groups(P＞0.05).The differences in body mass index(BMI),serum creatinine(SCr),N-terminal pro-brain natriuretic peptide(NT-proBNP),left ventricular end-diastolic diameter(LVEDD),left atrial diameter(LAD)and left ventricular ejection fraction(LVEF)had statistical significance between 2 groups(P＜0.05).The results of multi-factor nonconditional Logistic analysis showed that BMI,SCr,NT-proBNP,LVEDD,LAD and LVEF were independent risk factors for CHF complicated by arrhythmia(P＜0.05).The occurrences of cardiac death,readmission due to HF exacerbation and acute coronary syndrome(ACS)were significantly higher in CHF+arrhythmia group than those in non-arrhythmia group(P＜0.05).The results of Spearman correlation coefficient analysis showed that BMI,NT-proBNP,LVEDD and LAD were positively correlated to prognosis,and SCr and LVEF were negatively correlated to prognosis in patients with CHF complicated by arrhythmia(P＜0.05).Conclusion There are many independent risk factors for CHF complicated by arrhythmia,and they are closely related to prognosis.These risk factors should be paid attention to and intervened in clinical practice.
