【摘要】 目的:研究阵发性和持续性房颤且心功能正常患者电转复前后BNP变化,探讨BNP在房颤中的作用。方法:采用放射免疫分析测定68名心功能正常的阵发性和持续性房颤患者电转复前后血浆BNP变化,并以34名正常窦性心律者为对照组。结果:房颤患者在成功的电转复后24h,血浆BNP水平明显地降低。30名阵发性房颤患者全部转为窦性心律,血浆BNP水平由转复前的(96±42)pg/ml降至(28±21)pg/ml;持续性房颤患者,则有28人转复为窦性节律,血浆BNP水平由转复前的(73±38)pg/ml降至(38±25)pg/ml。结论:在有心脏疾病的患者,房颤影响血浆BNP的分泌。更多还原

【Abstract】 Objective To study the changes of plasma brain natriuretic peptide(BNP) levels before and after sinus rhythm restoration in patients with paroxysmal or persistent atrial fibrillation(AF) but normal left ventricle function and to explore the role of BNP in AF. Methods Plasma BNP levels were measured with RIA in 68 patients and 34 controls. Results Twenty four hours after successful cardioversion, plasma BNP levels decreased significantly in all the patients. The 30 patients with paroxysmal atrial fibrillation were all restored to sinus rhythm and levels of plasma BNP dropped from 96±42pg/ml to 28±21pg/ml. Of the 38 patients with persistent atrial fibrillation, 28 of them were restored to sinus rhythm, in whom levels of plasma BNP dropped from 73±38pg/ml to 38±25pg/ml. Conclusion The presence of AF should be taken into consideration when interpreting plasma BNP levels in patients with heart disease.更多还原
