BackgroundReadmission after ST‐segment–elevation myocardial infarction (STEMI) poses an enormous economic burden to the US healthcare system. There are limited data on the association between length of hospital stay (LOS), readmission rate, and overall costs in patients who underwent primary percutaneous coronary intervention for STEMI.Methods and ResultsAll STEMI hospitalizations were selected in the Nationwide Readmissions Database from 2010 to 2014. From the patients who underwent primary percutaneous coronary intervention, we examined the 30‐day outcomes including readmission, mortality, reinfarction, repeat revascularization, and hospital charges/costs according to LOS (1–2, 3, 4, 5, and >5 days) stratified by infarct locations. The 30‐day readmission rate after percutaneous coronary intervention for STEMI was 12.0% in the anterior wall (AW) STEMI group and 9.9% in the non‐AW STEMI group. Patients with a very short LOS (1–2 days) were readmitted less frequently than those with a longer LOS regardless of infarct locations. However, patients with a very short LOS had significantly increased 30‐day readmission mortality versus an LOS of 3 days (hazard ratio, 1.91; CI, 1.16–3.16 [P=0.01]) only in the AW STEMI group. Total costs (index admission+readmission) were the lowest in the very short LOS cohort in both the AW STEMI group (P<0.001) and the non‐AW STEMI group (P<0.001).ConclusionsFor patients who underwent primary percutaneous coronary intervention for STEMI, a very short LOS was associated with significantly lower 30‐day readmission and lower cumulative cost. However, a very short LOS was associated with higher 30‐day mortality compared with at least a 3‐day stay in the AW STEMI cohort.

住院时间，30天再入院率和原发性经皮冠状动脉介入治疗后ST段抬高型心肌梗塞费用之间的关联：全国再入院数据库分析。

背景：ST段抬高型心肌梗死后的再入院（STEMI）给 我们医疗系统。关于住院时间长短的相关数据有限（视线），经再次经皮冠状动脉介入治疗的患者的再入院率和总费用 STEMI方法和结果全部 STEMI 我们从2010年至2014年在全国再入院数据库中选择了住院治疗。从接受原发性经皮冠状动脉介入治疗的患者中，我们检查了30天的结局，包括再入院，死亡率，再次梗塞，再次血运重建和医院收费/费用，具体取决于 视线（1–2、3、4、5和> 5天）按梗塞部位分层。经皮冠状动脉介入治疗后30天再入院率STEMI 在前壁是12.0％（AW） STEMI 组和9.9％的非AW STEMI组。病人很短视线 （1-2天）的重新录入频率比更长的人少 视线不论梗塞位置如何。但是，患者视线 相较于 视线3天（危险比，1.91； CI，1.16-3.16 [ P = 0.01]）仅在AW STEMI组。总成本（索引录入和再录入）在短时间内是最低的视线 在这两个队列中 AW STEMI组（P <0.001）和非AWSTEMI组（P <0.001）。结论对于接受了原发性经皮冠状动脉介入治疗的患者STEMI，很短 视线与30天再入院率明显降低和累计成本降低有关。但是，很短视线 与至少30天的住院时间相比，与30天的较高死亡率相关 AW STEMI 队列。
