Between January 1975 and March 1978, 15 cases of sudden death or hospitalized medical emergencies occurred during cross-country skiing in the Engadine region, comprising 3 sudden deaths, 9 myocardial infarctions, and 3 neurovascular accidents. The total number is small as compared to the number of people practising this sport. Among participants of the Engadine Ski Marathon, the incidence was 1 emergency per 40,000 skiing hours and 1 death per 120,000 skiing hours. Patients suffering from myocardial infarctions were all vacationers from lower altitudes, in most whom several risk factors were present. Two cases of cerebrovascular accident demonstrate that competitive cross-country skiing may impose enormous stress on the cerebrosvascular system even in well-trained individuals.
1975年1月至1978年3月期间，恩加丁地区在越野滑雪过程中发生了15起猝死或需住院治疗的医疗紧急情况，其中包括3例猝死、9例心肌梗死和3例神经血管意外。与从事这项运动的人数相比，总数较少。在恩加丁滑雪马拉松的参与者中，发病率为每40000个滑雪小时出现1次紧急情况，每120000个滑雪小时出现1例死亡。心肌梗死患者均为来自低海拔地区的度假者，其中大多数人存在多种风险因素。两例脑血管意外表明，即使是训练有素的人，竞技越野滑雪也可能给脑血管系统带来巨大压力。
