The sudden cardiac death (SCD) of Zhang Xuefeng, an online influencer and well-known tutor specializing in China's college entrance examinations, has triggered an outpouring of grief online while also drawing widespread attention to the heart health risks. Chinese medical experts said the condition is showing a worrying trend toward younger generations, often linked to high-risk factors such as chronic sleep deprivation, excessive fatigue and unhealthy lifestyles.张雪峰——一位专注于中国高考的网络网红和知名辅导员——突发心脏病（SCD），引发了网络上的哀悼，同时也引起了人们对心脏健康风险的广泛关注。中国医学专家表示，该病在年轻一代中呈现出令人担忧的趋势，通常与慢性睡眠不足、过度疲劳和不健康生活方式等高风险因素有关。Experts noted that SCD in younger individuals can be even more dangerous than in older populations. 专家指出，年轻人的SCD比老年人更危险。
Wang Fang, a physician at Peking Union Medical College Hospital, emphasized that both athletes and those with sedentary lifestyles fall into high-risk categories, underscoring the importance of balanced physical activity. "Young people should avoid both extremes, pushing themselves into excessive high-intensity exercise or avoiding physical activity altogether. Cardiopulmonary exercise testing is the preferred method to accurately assess exercise intensity," .北京协和医学院医院的医生王方强调，运动员和久坐生活方式的人都属于高风险类别，强调了均衡体育活动的重要性。“年轻人应避免这两者，要么逼自己过度高强度运动，要么完全避免体育活动。心肺运动测试是准确评估运动强度的首选方法，“。
Wang added that symptoms such as bluish lips or fingernails, jaw or gum pain after exercise, may also serve as warning signals. In some cases, carrying nitroglycerin tablets may be advisable. She also stressed the importance of learning how to use an AED, which can be critical during the "golden four minutes" for emergency response.王博士补充说，运动后嘴唇或指甲发青、下颌或牙龈疼痛等症状，也可能是警示信号。在某些情况下，携带硝化甘油片片可能是建议的。她还强调了学习如何使用AED的重要性，这在紧急响应的“黄金四分钟”中至关重要。
