The length of hospital stay for uncomplicated myocardial infarction is still a debatable issue. Our study tries to establish the rate of patients amenable early discharged and the safety of this practice.
We studied retrospectively the clinical features, in-hospital events and 30-day follow up of 238 patients discharged early (5 or 6 days) during the last three years. These patients were compared with the remaining group of 929 patients discharged after a conventional stay (mean 10.4 days) in the same time frame.
The mean hospital stay in the early discharged group was 5.4 days. They had no ischemic, arrhythmic or haemodynamic complications in the acute phase. In the 30-day follow up there was only one death (at the 14 th post-myocardial infarction day) and 17 readmissions to the hospital, none with re-infarction. By contrast, there were 14 deaths and 43 readmissions among the patients with the standard stay at the hospital.
At least 20% of patients with uncomplicated myocardial infarction can be discharged early. This practice seems to be safe in low risk groups, and is not associated with a higher rate of complications when compared with longer hospital stays.
无并发症心肌梗死患者的住院时间仍是一个有争议的问题。我们的研究旨在确定可早期出院的患者比例以及这种做法的安全性。
我们回顾性研究了过去三年中238例早期（5或6天）出院患者的临床特征、住院期间事件及30天随访情况。将这些患者与同期929例常规住院（平均10.4天）后出院的其余患者组进行比较。
早期出院组的平均住院时间为5.4天。他们在急性期无缺血、心律失常或血流动力学并发症。在30天随访中，仅有1例死亡（在心肌梗死后第14天），17例再次入院，均无再次梗死。相比之下，常规住院患者中有14例死亡和43例再次入院。
至少20%的无并发症心肌梗死患者可早期出院。这种做法在低风险组中似乎是安全的，与较长住院时间相比，并发症发生率并未更高。
