Interventional cardiologists are held accountable for delay in the door-to-balloon time (DBT) for patients undergoing primary percutaneous coronary intervention in the setting of ST-elevation myocardial infarction (STEMI) even though in the chain of STEMI activation, the interventional cardiologist is the last person that needs to be available to start angiography. The goal of our study is to conduct a thorough analysis of the DBT data to assess time delays by randomly evaluating two consecutive years at the University of Arizona Medical Center (UAMC). We evaluated all available DBT data for STEMIs occurring in the fiscal years of 2011 and 2012 at the UAMC and calculated the time needed for the cardiologist to start the procedure after the patient was ready in the cardiac catheterization laboratory called time to start the procedure (TSP) in addition to other time intervals. Mean TSP time was 4 minutes and 24 seconds, one of the shortest time delays in the chain of STEMI activation and DBT. The median TSP delay was 3 minutes. The longest delay interval was the STEMI team's arrival to with a mean of 17 minutes and 38 seconds. Our data are the first to evaluate delays related to DBT revealing the least delay occurring due to the late arrival of Interventional cardiologists. Our data emphasizes the importance of performing a detailed time analysis of the DBT.
对于接受ST段抬高型心肌梗死（STEMI）直接经皮冠状动脉介入治疗的患者，介入心脏病专家要对门球时间（DBT）延迟负责，尽管在STEMI救治流程中，介入心脏病专家是最后一个需要到场开始血管造影的人。我们研究的目的是对DBT数据进行全面分析，通过随机评估亚利桑那大学医学中心（UAMC）连续两年的数据来评估时间延迟情况。我们评估了UAMC在2011财年和2012财年发生的所有STEMI患者的可用DBT数据，并计算了除其他时间间隔外，心脏病专家在患者于心导管实验室准备好后开始手术所需的时间，即开始手术时间（TSP）。平均TSP时间为4分24秒，是STEMI救治流程和DBT中时间延迟最短的环节之一。TSP延迟的中位数为3分钟。最长的延迟间隔是STEMI团队到达的时间，平均为17分38秒。我们的数据首次评估了与DBT相关的延迟，揭示了因介入心脏病专家迟到导致的延迟最少。我们的数据强调了对DBT进行详细时间分析的重要性。
