摘要:

目的 探究CT定量左心结构参数与肥厚型心肌病(HCM)合并心房颤动(AF)射频消融术(RFCA)后复发的关系。方法 选取120例HCM合并AF患者,根据患者RFCA术后6个月有无复发分为复发组与未复发组。患者均进行CT检查,分析得到2组的左室射血分数(LVEF)、左房射血分数(LAEF)、左房容积指数(LAVI)、左心耳体积等左心结构参数。收集患者临床资料,Logistic回归模型分析HCM合并AF患者RFCA术后复发的影响因素。受试者工作特征(ROC)曲线分析左心结构参数对HCM合并AF患者RFCA术后复发的预测效能。结果 复发组患者LAVI及左心耳体积高于未复发组,LAEF低于未复发组(P<0.05);Logistic回归分析结果显示,持续性房颤及高水平的LAVI、左心耳体积是HCM合并AF患者RFCA术后复发的独立危险因素,高水平LAEF是其保护因素(P<0.05);ROC曲线分析结果显示,LAVI、LAEF及左心耳体积联合预测HCM合并AF患者RFCA术后复发的曲线下面积(AUC)为0.902,高于各项单独检测的0.789、0.755、0.675,三者联合预测效能高于各项单独检测(Z分别为2.177、2.555,3.628,P<0.05)。结论 LAVI、左心耳体积升高,LAEF降低是RFCA术后复发的危险因素,三者联合检测对于HCM合并AF患者RFCA术后复发具有较高的预测价值。

Abstract:

Objective To explore the relationship between CT quantitative left heart structure parameters and recurrence after hypertrophic cardiomyopathy (HCM) and atrial fibrillation (AF) radiofrequency ablation (RFCA). Methods A total of 120 patients with HCM and AF admitted to our hospital from April 2021 to June 2023 were selected. Patients were divided into the relapse group and the non-recurrence group according to whether RFCA recurred 6 months after operation. All patients underwent CT examination, and left ventricular ejection fraction (LVEF), left atrial ejection fraction (LAEF), left atrial volume index (LAVI) and left atrial auricular volume of the two groups were analyzed. The clinical data of patients were collected. Logistic regression model was used to analyze the influencing factors of postoperative recurrence of RFCA in HCM patients with AF. Receiver operating characteristic curve (ROC) curve was used to analyze the predictive efficacy of left heart structure parameters for postoperative recurrence of RFCA in HCM patients with AF. Results The volume levels of LAVI and left auricle were higher in the relapsed group than those in the non-relapsed group, and the level of LAEF was lower than those in the non-relapsed group (P<0.05). Logistic regression analysis showed that persistent atrial fibrillation, LAVI and high left atrial appendage volume were independent risk factors for postoperative recurrence in HCM patients with AF (P<0.05), and high LAEF was protective factor (P<0.05). The results of ROC curve analysis showed that the AUC value of LAVI, LAEF and left atrial appendage volume in predicting recurrence after RFCA in patients with HCM and AF was 0.902, which was higher than that of 0.789, 0.755 and 0.675 of each individual test. The combined prediction efficiency of the three tests was higher than that of each single test (Z=2.177, 2.555 and 3.628, P<0.05). Conclusion High level of LAVI and left atrial appendage volume and low level of LAEF are risk factors for postoperative recurrence of RFCA. The combined detection of the three methods has high predictive value for postoperative recurrence of RFCA in HCM patients with AF.
