The helicopter transport of acute cardiac patients has become increasingly common, although no study has examined solely the effect of such transport on outcome in this subset of patients. A combined air and ground critical care transport service provided the opportunity for a direct comparison of patients with acute cardiac conditions (myocardial infarction or unstable angina) transported either by our helicopter or by a specially equipped critical care ground vehicle. Both air and ground components were similarly equipped in terms of personnel and medical equipment. Seventy-eight (27 ground, 51 air) transport cases were studied. Both patient groups were comparable in terms of age, sex, Killip classification, and diagnosis. Serious untoward events, defined as arrhythmias, chest pain, hypotension, bradycardia, seizures, and cardiac arrest, occurred in 41% of air transports and 7.5% of ground transports (P less than .002). The overall incidence of untoward events was also significantly greater with air transports (25/51, or 49%) than with the ground vehicle (4/27, or 15%; P less than .005). The reasons for these differences are unknown.
急性心脏病患者的直升机转运已变得越来越普遍，尽管尚无研究专门考察此类转运对这部分患者预后的影响。一项空中与地面联合的重症护理转运服务提供了一个机会，可对通过我们的直升机或配备特殊设备的重症护理地面车辆转运的急性心脏病患者（心肌梗死或不稳定型心绞痛）进行直接比较。空中和地面部分在人员和医疗设备方面配备相似。共研究了78例转运病例（27例地面转运，51例空中转运）。两组患者在年龄、性别、Killip分级和诊断方面具有可比性。严重不良事件定义为心律失常、胸痛、低血压、心动过缓、癫痫发作和心脏骤停，发生在41%的空中转运病例和7.5%的地面转运病例中（P<0.002）。空中转运的不良事件总发生率（25/51，即49%）也显著高于地面车辆转运（4/27，即15%；P<0.005）。这些差异的原因尚不清楚。
