目的探讨急性ST段抬高型心肌梗死(STEMI)患者急诊介入治疗门-囊时间(患者入院至首次球囊扩张的时间)的影响因素。方法回顾性分析潞河医院2008年1月—2009年1月连续收治的198例急诊介入治疗的STEMI患者的门-囊时间的影响因素。按门-囊时间的不同将患者分为两组:A组(≤120min)和B组(>120min),应用logistic回归分析影响门-囊时间的因素。结果单因素分析筛选出12个影响门-囊时间的因素(P均<0.05);12个因素进行多因素非条件Logistic回归分析发现5个变量与门-囊时间明显相关(P均<0.05)。结论多数STEMI患者的门-囊时间超过指南要求,临床因素和院内机制与长门-囊时间相关,应当建立起有效的机制来降低院内延迟。
Objective To investigate the influencing factors of portal-sac space time (patient admission to first balloon dilatation) in acute ST-segment elevation myocardial infarction (STEMI). Methods A retrospective analysis was performed on 198 patients with STEMI admitted to Luhe Hospital between January 2008 and January 2009. The patients were divided into two groups according to the portal-capsule time: group A (≤120min) and group B (> 120min). Logistic regression analysis was used to analyze the factors influencing the gate-capsule time. Results A total of 12 variables influencing the gate-capsule time were screened out by univariate analysis (P <0.05). The 12 variables were analyzed by multivariate non-conditional logistic regression analysis. Five variables were significantly correlated with the gate-capsule time (P <0.05) . CONCLUSION: In most STEMI patients, the gate-capsule time exceeds the guidelines, and clinical factors and hospital mechanisms are associated with long gate-capsule time. Effective mechanisms should be established to reduce in-hospital delays.
