背景：低人口密度可能与急性心肌梗死（AMI）患者的高死亡率有关。本研究的目的是探讨日本人口密度和医院首次经皮冠状动脉介入治疗（PCI）容量对AMI住院死亡率的影响。方法与结果：对64,414例急性心肌梗死患者进行回顾性研究。主要结局指标为住院死亡率。人口密度中位数为1147人/km（四分位数间距为342 ~ 5210人/km）。人口密度与住院死亡率呈显著负相关(OR为人口密度下降四分位数为1.086,95% CI为1.042-1.132，P
Background: Low population density may be associated with high mortality in acute myocardial infarction (AMI) patients. The purpose of this study was to investigate the effect of population density and hospital primary percutaneous coronary intervention (PCI) volume on AMI in-hospital mortality in Japan.Methods and Results: This is a retrospective study of 64,414 AMI patients transported to hospital by ambulances. The main outcome measure was in-hospital mortality. The median population density was 1,147 (interquartile range, 342-5,210) persons/km(2). There was a significant negative relationship between population density and in-hospital mortality (OR for a quartile down in population density 1.086, 95% CI 1.042-1.132, P
