While emergency medical service (EMS) response time (ERT) is a major factor associated with the survival of patients with cardiovascular disease (CVD), relatively few studies have explored the factors associated with ERT. This study aimed to assess the current status of ERT and to identify the factors affecting ERT in patients with CVD in China. Between January 1, 2011 and December 31, 2015, EMS responses to CVD incidents in Guangzhou, China, were examined. The primary outcome was ERT, defined as the time from receipt of an emergency call to the arrival of paramedics on the scene. Factors associated with ERT were evaluated by multivariable logistic regression. A total of 44 383 CVD incidents were analysed. The median ERT was 12.58 min (interquartile range=9.98-15.67). Among the risk factors, distance (OR=13.73, 95% CI=11.76-16.04), level of hospital (OR=1.57, 95% CI=1.40-1.75), and site of the incident (OR=1.53, 95% CI=1.38-1.69) were the top three significant factors affecting the ERT. Our results suggest that greater attention should be given to factors affecting the ERT. It is essential to make continuous efforts to promote the development of effective interventions to reduce the response time.
虽然紧急医疗服务 (EMS) 反应时间 (ERT) 是与心血管疾病 (CVD) 患者生存相关的主要因素，但很少有研究探讨与 ERT 相关的因素。本研究旨在评估中国 CVD 患者的 ERT 现状，并确定影响 ERT 的因素。2011 年 1 月 1 日至 2015 年 12 月 31 日期间，研究人员检查了中国广州 EMS 对 CVD 事件的反应。主要结局是 ERT，定义为从接到急救电话到急救人员到达现场的时间。通过多变量逻辑回归评估与 ERT 相关的因素。共分析了 44383 例 CVD 事件。ERT 的中位数为 12.58 分钟（四分位距=9.98-15.67）。在危险因素中，距离（OR=13.73，95%CI=11.76-16.04）、医院级别（OR=1.57，95%CI=1.40-1.75）和事件发生地点（OR=1.53，95%CI=1.38-1.69）是影响 ERT 的前三大显著因素。我们的研究结果表明，应更加关注影响 ERT 的因素。必须不断努力，推动制定有效的干预措施，以缩短反应时间。
