摘要 目的探讨老年高血压患者中血浆脑钠肽(BNP)水平与阵发性心房颤动(PAF)的关系。方法观察36例有PAF的老年高血压患者(A组)的血浆BNP水平、左房内径(LAD)和左室射血分数(LVEF),与36例无PAF病史的高血压患者(B组)进行比较;在有PAF的老年高血压患者中,观察了19例患者在窦性心律时和房颤发作期的血浆BNP水平作对照,并以5例患者在房颤发作前、中、后的血浆BNP水平对照。结果有PAF病史者血浆BNP水平显著高于无PAF病史者[(69.99±55.18)μg/L比(32.21±22.80)μg/L,P<0.01]、LVEF显著低于无PAF病史者[(61±8)%比(67±5)%,P<0.05],两组左房内径无差异。19例PAF者房颤发作时的血浆BNP水平显著高于窦性心律时[(132.45±46.68)μg/L比(62.72±38.40)μg/L,P<0.01],5例PAF者房颤发作时的血浆BNP水平显著高于房颤发作前及房颤中止后的BNP水平[(143.56±57.68)μg/L比(79.68±27.08)μg/L及(143.56±57.68)μg/L比(95.88±38.39)μg/L,P<0.05]。结论PAF发作影响老年高血压患者的BNP释放。窦性心律时血浆BNP水平可能用于预测老年高血压患者PAF的发生。
