To describe the reported incidence of out of hospital cardiac arrest (OHCA) and the characteristics and outcome after OHCA in relation to population density in Sweden.
All patients participating in the Swedish Cardiac Arrest Register between 2008 and 2009 in (a) 20 of 21 regions (n=6457) and in (b) 165 of 292 municipalities (n=3522) in Sweden, took part in the survey.
The regional population density varied between 3 and 310 inhabitants per km(2) in 2009. In 2008-2009, the number of reported cardiac arrests varied between 13 and 52 per 100,000 inhabitants and year. Survival to 1 month varied between 2% and 14% during the same period in different regions. With regard to population density, based on municipalities, bystander CPR (p=0.04) as well as cardiac etiology (p=0.002) were more frequent in less populated areas. Ambulance response time was longer in less populated areas (p<0.0001). There was no significant association between population density and survival to 1 month after OHCA or incidence (adjusted for age and gender) of OHCA.

描述瑞典院外心脏骤停（OHCA）的报告发生率以及与人口密度相关的 OHCA 患者特征和结局。
2008 年至 2009 年，所有参与瑞典心脏骤停登记处的患者（a）21 个地区中的 20 个（n=6457）和（b）瑞典 292 个市中的 165 个（n=3522）参加了此项调查。
2009 年，区域人口密度在 3 至 310 人/平方公里之间变化。在 2008-2009 年期间，报告的心脏骤停数量在不同地区每年每 100,000 居民中为 13 至 52 例。同一时期不同地区的 1 个月生存率在 2%至 14%之间变化。关于人口密度，基于市，旁观者心肺复苏术（p=0.04）以及心脏病因（p=0.002）在人口较少的地区更为常见。人口较少的地区救护车反应时间较长（p<0.0001）。OHCA 后 1 个月生存率或 OHCA 的发生率（按年龄和性别调整）与人口密度之间无显著相关性。
