目的探讨夜间非勺型心率与急性心肌梗死(AMI)经皮冠状动脉介入治疗(PCI)术后发生不良心脏事件(MACE)的关系。方法根据24h动态心电监测结果将PCI术后的AMI患者分为夜间非勺型心率组(A组)及夜间勺型心率组(B组)。比较两组患者随访期间主要不良心脏事件(MACE)和再次住院率。结果 A组患者的MACE、心源性死亡、靶血管再次血运重建和再次住院率分别为27.4%、8.1%、14.5%、23.4%,均明显高于B组(p<0.05),但两组的非致死性心肌梗死发生率无显著性差异(4.8%vs 1.2%,p=0.123)。结论夜间非勺型心率有助于早期识别AMI患者PCI术后发生心脏不良事件的高危人群。
Objective To investigate the relationship between nocturnal non-spoon heart rate and adverse cardiac events (MACE) after percutaneous coronary intervention (PCI) in acute myocardial infarction (AMI). Methods The AMI patients after PCI were divided into nocturnal non-scalp heart rate group (A group) and night scalp heart rate group (B group) according to 24h ambulatory electrocardiogram monitoring results. The incidence of major adverse cardiac events (MACE) and hospitalizations during the follow-up period were compared between the two groups. Results The MACE, cardiac death, target revascularization and rehospitalization rates in group A were significantly higher than those in group B (27.4%, 8.1%, 14.5%, 23.4%, respectively) (P <0.05) There was no significant difference in the incidence of nonfatal myocardial infarction (4.8% vs 1.2%, p = 0.123). Conclusions The non-dipper heart rate at night is helpful for the early identification of high-risk patients with AMI after PCI.
