111例急性心肌梗死（AMI）发病到溶栓时间为232．5±124．0min，其中发病到来院时间144．2±119．2min，来院到溶栓时间（DNT）87．6±52．3min。79例溶栓血管再通患者之DNT短于32例未溶通者（77．4±47．9比112．8±53．6min，P＜0．002）；DNT中，就诊到入院时间未通组长于溶通组（87．0±48．9比55．1±43．8min，P＜0．002）。溶栓延迟原因有：在院外患者对病情认识不足或就诊不便；院内办手续和住院缓慢以及急诊留观等。DNT≤45min的26例AMI中，18例（69．2％）系在急诊室溶栓。
111 cases of acute myocardial infarction (AMI) onset to thrombolysis time was 232.5 ± 124.0min, onset of hospital arrival time of 144.2 ± 119.2min, hospitalization to thrombolytic time (DNT) 87.6 ± 52.3min . The DNT of 79 patients with thrombolytic recanalization was shorter than 32 patients with non-recanalization (77.4 ± 47.9 vs 112.8 ± 53.6 min, P <0.002) The group leader was in the dissolvent group (87.0 ± 48.9 vs 55.1 ± 43.8 min, P <0.002). Thrombolytic delay due to: in patients with outpatient or lack of understanding of the condition of the inconvenience; in-hospital procedures and hospitalization slow and stay in sight and so on. Twenty-six patients (69.2%) of 26 AMI patients with DNT ≤ 45 min were thrombolyzed in the emergency room.
