摘要 目的:探讨频发房性期前收缩(FPAC)与老年急性ST段抬高型心肌梗死(STEMI)患者新发心房颤动(NOAF)的相关性及预测价值。方法:选取2020年4月至2021年4月间绵阳市中心医院收治的120例老年STMEI患者作为研究对象。依据患者的24 h房性期前收缩(PAC)次数进行分组,将PAC频率≥720次/24 h者纳入FPAC组,将PAC频率<720次/24 h者纳入非FPAC组。对比两组患者出现NOAF的情况,并分别以是否出现NOAF进行分组,采用二元Logistic回归方程分析影响NOAF的危险因素,绘制ROC曲线评估FPAC在预测老年STMEI患者NOAF中的价值。结果:120例患者中FPAC患者有21例(占17.50%),非FPAC患者有99例(占82.50%)。非FPAC组患者的24 h PAC次数、NOAF发生率均显著低于FPAC组患者(P<0.05)。经单因素及Logistic回归分析显示,高血压、心力衰竭、FPAC、左室射血分数(LVEF)降低、左心房内径(LAD)增大是导致老年急性STMEI患者出现NOAF的危险因素(P<0.05)。经ROC曲线分析显示,FPAC预测老年急性STMEI患者NOAF的曲线下面积(AUC)为0.733,95%置信区间为0.449~1.000,预测敏感度为80.0%、特异度为66.7%,cut off值为983次/24 h。结论:老年STEMI患者的PAC频率与NOAF密切相关,且能够作为预测NOAF的指标之一。
