摘要:
目的 探讨沙库巴曲缬沙坦预防心房颤动(AF)射频消融术(RFCA)后心室重构的效果及对患者炎症因子的影响,以期为临床治疗提供新策略。 方法 选取2022年1月—2023年10月湖州市中心医院收治的152例AF患者,均行RFCA术,采用随机信封法分常规组(接受术后常规治疗)和治疗组(在常规组的基础上加用沙库巴曲缬沙坦), 各76例。比较2组治疗前后心室重构指标、炎症因子水平及房颤复发、不良反应发生情况。 结果 治疗60 d后,治疗组患者左心室射血分数、QRS电压均高于常规组(P<0.05),左心室舒张末期内径、心室收缩末期内径、室间壁厚度、P波离散度、QRS时限均低于常规组(P<0.05);治疗60 d后,治疗组患者血清C反应蛋白、白细胞介素-6分别为(5.33±1.27)mg/L、(5.44±1.15)pg/mL,均低于常规组的(6.38±1.18)mg/L、(7.08±1.44)pg/mL(F=28.281、61.441,均P<0.05);2组患者治疗后3、6、12个月的房颤累计复发率比较差异无统计学意义(P>0.05);2组患者用药不良反应发生率比较差异无统计学意义(P>0.05)。 结论 沙库巴曲缬沙用于AF患者RFCA术后可有效改善患者心室重构,减轻炎症反应,且安全性高。 Abstract:Objective To investigate the effect of sacubitril valsartan on the prediction of ventricular remodeling after radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF) and analyze its influence on inflammatory factors, with a view to providing a new strategy for clinical treatment. Methods A total of 152 AF patients in Huzhou Central Hospital from January 2022 to October 2023 were selected and received RFCA. After surgery, according to the random envelope method, patients were divided into a conventional group (receiving conventional postoperative treatment) and a treatment group (sacubitril valsartan in addition to the conventional group), with 76 cases in each group. The indicators of ventricular remodeling, inflammatory factors, recurrence of atrial fibrillation, and adverse reactions before and after treatment were compared between the two groups. Results After 60 days of treatment, the left ventricular ejection fraction and QRS voltage of patients in the treatment group were higher than those in the conventional group (P < 0.05), while the left ventricular end-diastolic diameter, end-systolic diameter, interventricular wall thickness, P wave dispersion and QRS duration were lower than those in the conventional group (P < 0.05). After 60 days of treatment, the levels of serum C-reactive protein and interleukin-6 in the treatment group with (5.33±1.27) mg/L and (5.44±1.15) pg/mL were lower than (6.38±1.18) mg/L and (7.08±1.44) pg/mL in the conventional group (F=28.281, 61.441, both P < 0.05). No statistical differences were observed in the cumulative recurrence rates of atrial fibrillation at 3, 6, and 12 months after treatment between the two groups (P>0.05). There were no statistical differences in the adverse drug reactions between the two groups (P>0.05). Conclusion Sacubitril valsartan can effectively improve ventricular remodeling and reduce the inflammatory response in AF patients after RFCA, and it has high safety. -
