血清醛固酮水平对不同类型房颤的鉴别价值

摘要

目的：探讨血清醛固酮水平对不同类型房颤的鉴别价值。方法：选择房颤患者153例，其中阵发性房颤99例，持续性房颤54例，测定血清醛固酮浓度，并与两种类型房颤进行相关性分析。结果：与阵发性房颤患者相比，持续性房颤患者血清醛固酮水平显著升高[（234.3±69.6） pg／ml比（302.7±78.3） pg／ml ， P＜0.01]。相关分析显示，醛固酮水平与心房内径和左室射血分数均呈明显正相关（ r＝0.896、0.831， P均＜0.01）。结论：血清醛固酮水平的高低有助于鉴别阵发性房颤与持续性房颤，并对病程转归有一定指导意义。%Objective:To explore distinguishing value of serum aldosterone level for different types of atrial fibrilla-tion (AF) .Methods:A total of 153 AF patients were selected ,including 99 patients with paroxysmal AF (paroxys-mal AF group) and 54 patients with persistent AF (persistent AF group) .Serum aldosterone concentration was measured ,and its correlation with two types of AF was analyzed .Results:Compared with patients with paroxysmal AF ,there was significant rise in serum aldosterone level [ (234.3 ± 69.6) pg/ml vs .(302.7 ± 78.3) pg/ml , P<0.01] in patients with persistent AF .Correlation analysis indicated that aldosterone level was positively correlated with atrial diameter and left ventricular ejection fraction (r=0.896 ,0.831 ,P<0.01 both) .Conclusion:Serum al-dosterone level is helpful to distinguishing paroxysmal atrial fibrillation and persistent atrial fibrillation ,and posses-ses certain guiding significance for outcome .
