入院时C反应蛋白与首次急性心肌梗死后新发心房颤动的相关性

目的 探讨首次急性心肌梗死患者入院时的C反应蛋白(CRP)与新发心房颤动的关系.方法 测定136例首次急性心肌梗死患者入院时的CRP,持续监测入院7 d内有无心房颤动发作,同时分析临床资料、心脏超声和冠状动脉造影检查的资料.结果 新发心房颤动的发生率是22.8%,根据是否发生心房颤动分成心房颤动组和非心房颤动组.单变量分析发现,心房颤动组的年龄、超敏CRP(hs-CRP)和合并高血压、前壁心肌梗死、左前降支和三支血管病变的构成比分别为(69.0±10.5)岁、(26.7±19.6)mg/L、71.0%、67.7%、71.0%和22.6%,均显著高于非心房颤动组的(60.2±12.3)岁、(13.1±12.7)mg/L、50.5%、47.6%、46.7%和8.6%(P值均＜0.05);左心房内径为(36.8±5.2)mm,显著大于非心房颤动组的(34.5±3.6)mm(P＜0.05);左心室射血分数为0.477±0.107,显著低于非心房颤动组的0.538±0.124(P＜0.05).多变量分析显示,年龄(OR=1.05,95%CI为1.00～1.13)和CRP水平(OR=1.28,95%CI为1.00～1.61)是新发心房颤动的独立预测因素(P值均＜0.05).结论 入院时的CRP水平是首次急性心肌梗死患者新发心房颤动的独立危险因素,提示炎性反应参与急性心肌梗死后新发心房颤动的发生.

Relationship between C-reactive protein at admission and new-onset atrial fibrillation after initial acute myocardial infarction

Objective To investigate the association between C-reactive protein(CRP)and new-onset atrial fibrillation(AF)in patients with initial acute myocardial infarction(AMI).Methods CRP was measured in 136 patients with initial AMI at admission.All patients were monitored continuously for new-onset AF for 7 days since admission.Clinical manifestations,echocardiographic data and angiographic data were also evaluated in all patients.Results AF occurred in 23% of patients.All patients were divided into a group with n...
