摘要
目的探讨应用常规及组织多谱勒超声心动图评估心房颤动合并射血分数保留型心力衰竭(HFpEF)患者行射频消融术(RFCA)后左心功能的效果。方法选取2022年1—8月在北部战区总医院确诊的心房颤动、拟行RFCA且伴有HFpEF的104例患者为研究对象。测定术前及术后3个月患者的左房内径、左室舒张末期内径、左房射血分数、三尖瓣返流速度、左房容积指数(LAVI)、左房舒张末期容积(LAEDV)、左房收缩末期容积(LAESV)、左室射血分数(LVEF)、二尖瓣环室间隔部位和侧壁部位舒张早期峰值速度、左室整体纵向应变(GLS)、左室整体轴向应变(GCS),评估RFCA前及术后的左心功能。结果RFCA术后,患者的左室舒张末期内径、GLS测定值、GCS测定值均低于术前,LAVI、二尖瓣环室间隔部位舒张早期峰值速度测定值、二尖瓣环侧壁部位舒张早期峰值速度测定值、LVEF均高于术前,差异均有统计学意义(P<0.05)。RFCA前后,患者的左房内径、左房射血分数、左房舒张末期容积、左房收缩末期容积、三尖瓣返流速度比较,差异均无统计学意义(P>0.05)。结论HFpEF合并心房颤动患者经RFCA后左心功能好转。LVEF、LAVI、二尖瓣环室间隔部位及侧壁部位舒张早期峰值速度可以量化评价行RFCA的心房颤动伴HFpEF患者左心功能变化。
Objective To investigate the effect of routine and tissue Doppler echocardiography in evaluating left heart function after radiofrequency ablation(RFCA)in patients with atrial fibrillation and heart failure with preserved ejection fraction(HFpEF).Methods A total of 104 patients with atrial fibrillation who were diagnosed in the General Hospital of Northern Theater Command from January to August 2022 and were scheduled to undergo RFCA with HFpEF were selected as the research objects.Determination of preoperative and postoperative 3 months in patients with left atrial diameter,left ventricular end-diastolic diameter,left atrial ejection fraction,speed of tricuspid regurgitation and left atrial volume index(LAVI),left atrial end-diastolic volume(LAEDV),left atrial systolic volume(LAESV),left ventricular ejection fraction(LVEF),mitral valve ring ventricular septal area and peak early diastolic wall parts Velocity,left ventricular global longitudinal strain(GLS),left ventricular global axial strain(GCS),and left ventricular function before and after RFCA were evaluated.Results After RFCA,the left ventricular end-diastolic diameter,GLS and GCS values were lower than those before operation,and LAVI,early peak diastolic velocity at the septal site of mitral annulus,early peak diastolic velocity at the lateral wall of mitral annulus,and LVEF were higher than those before operation,and the differences were statistically significant(P<0.05).There were no significant differences in left atrial diameter,left atrial ejection fraction,left atrial end-diastolic volume,left atrial end-systolic volume,and tricuspid regurgitation velocity before and after RFCA(P>0.05).Conclusion The left ventricular function of HFpEF patients with atrial fibrillation improved after RFCA.LVEF,LAVI,mitral annulus septum and lateral wall early diastolic peak velocity can quantify the changes of left heart function in patients with atrial fibrillation and HFpEF undergoing RFCA.
