The hospital courses of 882 consecutive patients with acute myocardial infarction admitted to the coronary care unit (CCU) during a 3-year period were evaluated. Their courses after discharge from the CCU were assessed with reference to the following serious complications which had occurred during their stay in the CCU; ventricular tachycardia or fibrillation, second-or third-degree heart block, pulmonary oedema, cardiogenic shock persistent sinus tachycardia, persistent hypotension, atrial flutter or fibrillation, or extension, or extension of infarction. Of the 494 patients (56%) with one or more of these complications, 38 (8%) died of cardiac causes in hospital after transfer from the CCU. Of 388 patients (44%) in the uncomplicated group, only 2(0,5%) died of cardiac causes after transfer from the CCU. The same patients were classified according to the Coronary Prognostic Index (CPI) of Norris. None of the 54% of patients with a CPI of less than 6 units died in hospital after transfer from the CCU. It is proposed that patients with a CPI of less than 6 units and with none of the listed serious complications during their CCU stay could safely be discharged from hospital earlier than is customary.
对连续3年入住冠心病监护病房（CCU）的882例急性心肌梗死患者的住院病程进行了评估。参照他们在CCU住院期间发生的以下严重并发症，对其从CCU出院后的病程进行了评估：室性心动过速或颤动、二度或三度房室传导阻滞、肺水肿、心源性休克、持续性窦性心动过速、持续性低血压、心房扑动或颤动，或梗死扩展。在有上述一种或多种并发症的494例患者（56%）中，38例（8%）从CCU转出后在医院死于心脏原因。在无并发症组的388例患者（44%）中，只有2例（0.5%）从CCU转出后死于心脏原因。根据诺里斯的冠状动脉预后指数（CPI）对相同患者进行分类。CPI小于6分的患者中，54%从CCU转出后均未在医院死亡。建议CPI小于6分且在CCU住院期间无上述所列严重并发症的患者，可以比常规情况更早安全出院。
