Background Early identification of warning symptoms among out-of-hospital cardiac arrest (OHCA) patients remains challenging. Thus, we examined the registered prodromal symptoms of patients who called medical helpline services within 30-days before OHCA. Methods Patients unwitnessed by emergency medical services (EMS) aged ≥18 years during their OHCA were identified from the Danish Cardiac Arrest Registry (2014-2018) and linked to phone records from the 24-h emergency helpline (1-1-2) and out-of-hours medical helpline (1813-Medical Helpline) in Copenhagen before the arrest. The registered symptoms were categorized into chest pain; breathing problems; central nervous system (CNS)-related/unconsciousness; abdominal/back/urinary; psychiatric/addiction; infection/fever; trauma/exposure; and unspecified (diverse from the beforementioned categories). Analyses were divided by the time-period of calls (0-7 days/8-30 days preceding OHCA) and call type (1-1-2/1813-Medical Helpline). Results Of all OHCA patients, 18% (974/5442) called helpline services (males 56%, median age 76 years[Q1-Q3:65-84]). Among these, 816 had 1145 calls with registered symptoms. The most common symptom categories (except for unspecified, 33%) were breathing problems (17%), trauma/exposure (17%), CNS/unconsciousness (15%), abdominal/back/urinary (12%), and chest pain (9%). Most patients (61%) called 1813-Medical Helpline, especially for abdominal/back/urinary (17%). Patients calling 1-1-2 had breathing problems (24%) and CNS/unconsciousness (23%). Nearly half of the patients called within 7 days before their OHCA, and CNS/unconsciousness (19%) was the most registered. The unspecified category remained the most common during both time periods (32%;33%) and call type (24%;39%). Conclusions Among patients who called medical helplines services up to 30-days before their OHCA, besides symptoms being highly varied (unspecified (33%)), breathing problems (17%) were the most registered symptom-specific category.
在院外心脏骤停 (OHCA) 患者中，早期识别预警症状仍然具有挑战性。因此，我们研究了在 OHCA 前 30 天内拨打医疗急救热线服务的患者的前驱症状。
从丹麦心脏骤停登记处 (2014-2018 年) 中确定了未被紧急医疗服务 (EMS) 目击的年龄≥18 岁的 OHCA 患者，并与哥本哈根 24 小时急救热线 (1-1-2) 和非工作时间医疗热线 (1813-医疗热线) 的电话记录进行了链接。登记的症状分为胸痛；呼吸问题；中枢神经系统 (CNS) 相关/意识丧失；腹部/背部/泌尿道；精神疾病/成瘾；感染/发烧；创伤/暴露；以及未指定的症状（与上述类别不同）。分析分为呼叫时间（OHCA 前 0-7 天/8-30 天）和呼叫类型（1-1-2/1813-医疗热线）。
所有 OHCA 患者中有 18%（974/5442）拨打了急救热线（男性占 56%，中位年龄 76 岁[Q1-Q3：65-84]）。在这些患者中，有 816 人拨打了 1145 次热线并登记了症状。最常见的症状类别（未指定的症状除外，占 33%）是呼吸问题（17%）、创伤/暴露（17%）、CNS/意识丧失（15%）、腹部/背部/泌尿道（12%）和胸痛（9%）。大多数患者（61%）拨打了 1813-医疗热线，尤其是腹部/背部/泌尿道（17%）。拨打 1-1-2 的患者有呼吸问题（24%）和 CNS/意识丧失（23%）。将近一半的患者在 OHCA 前 7 天内打电话，登记的最常见症状是 CNS/意识丧失（19%）。未指定的症状在两个时间段（32%；33%）和呼叫类型（24%；39%）中仍然是最常见的症状。
在 OHCA 前 30 天内拨打医疗急救热线服务的患者中，除了症状高度多样化（未指定的症状（33%））外，呼吸问题（17%）是登记的最常见特定症状类别。
