Alpine tourism annually attracts over 100 million visitors globally. Age and cardiovascular comorbidities in alpine tourists are increasing, and rates of out-of-hospital cardiac arrest (OHCA) have been hypothesized to be higher due to exertion and physiological stress.
Cases of alpine OHCA from 2002 to 2021 were identified from the statewide Victorian Ambulance Cardiac Arrest Registry. Alpine and nonalpine OHCA characteristics were compared. Causes of alpine OHCA were obtained from hospital discharge diagnoses and the National Coronial Information System.
Approximately 15.3 million alpine visits were recorded over the time period, during which 13 alpine OHCAs occurred (0.04% of 32,179 OHCAs, 0.8 OHCAs per million alpine visits). Compared with nonalpine OHCAs in a public setting, alpine OHCA patients were younger (median age 52 years vs 63 years, .0373), with higher rates of bystander defibrillation (54.5% vs 13.5%, .0001). Survival to hospital discharge did not significantly differ between alpine (38.5%) and nonalpine OHCA patients. Ischemic heart disease was the commonest identified cause of alpine OHCA in both survivors and nonsurvivors.
Alpine OHCA is very rare in Australia, accounting for 1 in 5000 OHCAs and fewer than 1 in a million ski field visitors. Despite remoteness and access challenges, alpine OHCA survival is high, driven by prognostically favorable arrest-related factors and coordinated local systems of care prioritizing early bystander intervention.
高山旅游每年在全球吸引超过1亿游客。高山游客的年龄和心血管合并症在增加，据推测，由于体力消耗和生理压力，院外心脏骤停（OHCA）的发生率更高。
从维多利亚州全州救护车心脏骤停登记处识别出2002年至2021年的高山OHCA病例。比较了高山和非高山OHCA的特征。高山OHCA的病因来自医院出院诊断和国家死因信息系统。
在此期间记录了约1530万次高山旅游，其中发生了13例高山OHCA（占32179例OHCA的0.04%，每百万次高山旅游中有0.8例OHCA）。与公共场所的非高山OHCA相比，高山OHCA患者更年轻（中位年龄52岁对63岁，P = 0.0373），旁观者除颤率更高（54.5%对13.5%，P < 0.0001）。高山OHCA患者（38.5%）和非高山OHCA患者出院存活率无显著差异。在幸存者和非幸存者中，缺血性心脏病是高山OHCA最常见的已确定病因。
在澳大利亚，高山OHCA非常罕见，占OHCA的五千分之一，在滑雪场游客中不到百万分之一。尽管存在偏远和交通不便的挑战，但由于与心脏骤停相关的预后有利因素以及优先考虑旁观者早期干预的协调地方护理系统，高山OHCA的存活率很高。
