This study aimed to compare air (AIR) and ground transport (GRD) of STEMI patients bound for primary percutaneous coronary intervention (pPCI).
This was a prospective, controlled, observational study, including patients in whom STEMI was suspected outside a 30-minute driving distance from the PCI centre. AIR patients in a 12-month period (May 1, 2010, to April 30, 2011) were compared with GRD patients in a 16-month period (January 1, 2010, to April 30, 2011). The primary endpoint was time from ECG consistent with STEMI to arrival in the cardiac catheterisation laboratory. We included 450 patients, 114 AIR and 336 GRD patients. The median (5-95% range) transport distance was 97 (62-162) vs. 94 (64-172) kilometres, respectively (p=0.01). Time from ECG to cardiac catheterisation laboratory arrival was significantly lower in the AIR group (median 84 minutes (60-160) vs.104 minutes [63-225], p<0.01). Time from ECG to balloon was 114 (78-221) minutes vs.132 (84-262) (p<0.01), respectively. The 30-day mortality was 2.2% (2/91) for AIR and 6.9% (18/262) for GRD patients (p=0.10). One-year mortality was 6.7%, (6/90) vs. 9.9% (26/262) (p=0.35), respectively.
Air transport seemed superior to ground transportation in reducing time from ECG diagnosis to arrival in the catheterisation laboratory for STEMI patients outside a 30-minute driving distance to the PCI centre.
本研究旨在比较经皮冠状动脉介入治疗（pPCI）前 STEMI 患者的空中（AIR）和地面转运（GRD）。
这是一项前瞻性、对照、观察性研究，纳入了距 PCI 中心 30 分钟车程以外怀疑发生 STEMI 的患者。在 12 个月的时间内（2010 年 5 月 1 日至 2011 年 4 月 30 日），AIR 患者与在 16 个月时间内（2010 年 1 月 1 日至 2011 年 4 月 30 日）的 GRD 患者进行比较。主要终点是从心电图符合 STEMI 到到达心导管实验室的时间。共纳入 450 例患者，其中 114 例 AIR 患者和 336 例 GRD 患者。转运距离中位数（5-95%范围）分别为 97（62-162）km 和 94（64-172）km（p=0.01）。AIR 组心电图至心导管实验室到达时间明显缩短（中位数 84 分钟[60-160]vs.104 分钟[63-225]，p<0.01）。心电图至球囊扩张时间分别为 114（78-221）分钟和 132（84-262）分钟（p<0.01）。AIR 组 30 天死亡率为 2.2%（2/91），GRD 组为 6.9%（18/262）（p=0.10）。AIR 组 1 年死亡率为 6.7%（6/90），GRD 组为 9.9%（26/262）（p=0.35）。
对于距 PCI 中心 30 分钟车程以外的 STEMI 患者，空中转运似乎比地面转运更能缩短心电图诊断至到达导管室的时间。
