摘要
目的：探讨术前血浆NT-pro-BNP和术前超声心动图左房内径对环肺静脉消融术治疗房颤术后复发的相关性，以提高房颤射频消融手术的成功率。方法70例行环肺静脉消融术的房颤患者，在术前检测血浆NT-pro-BNP，经胸超声心动图测量左房内径，经食道超声心动图了解有无左房内血栓形成。15例有左房内血栓形成者未行环肺静脉消融术，余下55例均成功行环肺静脉消融术。术后随诊，每月复查心电图，动态心电图了解有无房颤的复发。3月后仍有房颤发生则认为手术失败。成功组39例、失败组16例。结果69%患者NT-pro-BNP高于正常范围。消融失败组NT-pro-BNP明显高于成功组，失败组左房内径明显大于成功组。结论对于NT-pro-BNP明显增高且左房内径又明显增大者行环肺静脉消融术治疗房颤则复发的可能性明显增加，可将术前NT-pro-BNP及左房内径作为房颤术前筛选患者的参考指标。
Abstract
Objective To explore the relationship of the levels of NT-pro-BNP and left atrial dimension and the incidence of recurrence AF after circumferential pulmonary vein ablation(CPVA). Methods Plasma NT-pro-BNP level and left atrial dimension was measured before CPVA in 70 AF patients without heart failure(EF>55%). Atrial thrombus was detected by transesophageal echocardiography in 15patients and CPVA was not performed in these patients.CPVA was successful in the remain 55 patients and follow up for 3 months. All patients were askd to underwen3 months is failure.39 patients were in successful group and 16 patients were in failure group. Result NT-pro-BNP exceeded the normal range in 69% patients. NT-pro-BNP level was significantly higher in failure group than in successful group. Left atrial(LA) dimension was larger in failure group than in successful group. Conclusion NT-pro-BNP and LA dimension are predictive of successful CPVA for AF patients.
