Aim

To investigate whether the aetiology of in-hospital cardiac arrest (IHCA) is associated with long-term survival after 30-day survival.

Methods

A nationwide registry-based cohort study was conducted using the Swedish Registry for Cardiopulmonary Resuscitation. Adult IHCA patients in Sweden between 2018 and 2023 who survived ≥30 days were included. Aetiologies were merged into six categories (myocardial ischemia [reference], other cardiac, pulmonary, infectious, haemorrhagic and other non-cardiac). Cox (proportional hazards) regression models were used to estimate crude and multivariable adjusted (demographics, comorbidities, arrest characteristics) hazard ratios (HRs) with 95% CIs for all-cause mortality.

Results

Among 2692 30-day survivors (median age 71 years; 67% male), 886 deaths (33%) occurred over a median 3.7-year follow-up; overall one‑year survival was 86%. In the fully adjusted model, higher hazards of death were observed for infectious (HR 1.79, 95% CI 1.30–2.47), haemorrhagic (1.71, 1.20–2.43), and pulmonary aetiologies (1.61, 1.24–2.11), compared to myocardial ischemia. No difference was observed for cardiac and other non‑cardiac aetiologies.

Conclusions

Aetiology of in-hospital cardiac arrest is independently associated with long‑term prognosis after 30‑day survival. Compared with myocardial ischemia, infectious, haemorrhagic and pulmonary causes are associated with higher long‑term mortality. These findings support aetiology‑informed follow‑up after IHCA.

目的探讨院内心脏骤停（IHCA）的病因是否与30天生存率相关。方法使用瑞典心肺复苏登记处进行了一项全国性的基于登记的队列研究。纳入了2018年至2023年间瑞典存活≥30天的成年IHCA患者。病因合并为6类（心肌缺血[参考文献]、其他心脏、肺部、感染性、出血性和其他非心脏）。Cox（比例风险）回归模型用于估计全因死亡率95% ci的粗糙和多变量调整（人口统计学、合并症、骤停特征）风险比（hr）。结果在2692例30天存活者中（中位年龄71岁，67%为男性），在中位3.7年随访期间发生886例（33%）死亡；总1年生存率为86%。在完全调整后的模型中，与心肌缺血相比，感染（HR 1.79, 95% CI 1.30-2.47）、出血（1.71,1.20-2.43）和肺部病因（1.61,1.24-2.11）的死亡风险更高。在心脏和其他非心脏病因方面没有观察到差异。结论院内心脏骤停的病因学与30天生存率后的长期预后独立相关。与心肌缺血相比，感染性、出血性和肺部原因与较高的长期死亡率相关。这些发现支持在IHCA后进行病因学知情的随访。
