医生介绍，心肌损伤是心肌炎的后果之一，心肌细胞受损后，化验单会显示心肌酶学升高，可能出现心 率过快或过慢，严重时超声可见心功能下降，这些都是心肌损伤的表现，心肌炎患者会出现不同形式的 心肌损伤。 为什么流感退烧好几天了，还会引发心肌炎？医生表示—— 呼吸道、消化道病毒感染后，由于儿童的各个器官和系统的免疫功能尚未成熟，病毒感染引发的病毒血 症会侵犯心肌，从而出现心肌炎。 病毒感染引发的全身损伤，一般来说有一周的自然病程，退烧后病毒损伤并没有完全停止，仍可能出现 心肌炎。 （来源：中国妇女网） 转自：中国妇女网 近日，北京的一位患儿在甲流退烧后的第3天，因为骑车运动一小时，产生呼吸不畅等症状，送医后被 诊断为心肌损伤。什么是心肌损伤？为什么退烧后运动会导致这类疾病？ 为什么流感退烧数日后仍会引发心肌炎？ 病毒是引起心肌炎的主要因素。冬季是病毒比较活跃的时期，比如流感病毒、腮腺炎病毒、疱疹病毒等 都可能入侵人体，引发心肌炎。那么，哪些人群容易被心肌炎盯上呢？ 退热后的第二阶段为"免疫阶段"，这个阶段的损伤可能更重，身体产生的抗体不仅攻击病毒，还会误将 感染的心肌当作异物进行攻击，引发免疫反应，退烧后仍可能造成阶段 ...

Group 1 - The article emphasizes the importance of avoiding strenuous exercise after catching a cold, as it may lead to serious health issues like viral myocarditis [3][11] - Symptoms of myocarditis include fever, body aches, and respiratory difficulties, which can escalate to heart-related issues if exercise is resumed too soon [5][11] - Viral myocarditis is primarily caused by viral infections, which are more prevalent during certain periods, highlighting the need for preventive measures against viruses [9][10] Group 2 - Recommendations for preventing viral infections include wearing masks in crowded places, maintaining hygiene during meals, avoiding overexertion, eating a balanced diet, and staying warm [10] - The article suggests a "neck rule" for determining exercise suitability during a cold, where symptoms above the neck may allow for light exercise, while symptoms below the neck warrant rest [13] - Overall, the article advocates for rest and recovery during illness rather than immediate physical activity, stressing that exercise should be a regular practice rather than a last-minute effort [13]

Core Viewpoint - The article discusses the onset of cold symptoms, particularly sore throat, as a signal of the immune system's response to viral infection rather than the beginning of the illness itself [6]. Group 1: Understanding Sore Throat and Immune Response - Sore throat is often the first symptom of a cold, indicating that the immune system is attacking the virus [6]. - When viruses invade throat cells, they trigger a response from the immune system, which sends immune cells to the site of infection and releases inflammatory mediators that cause pain [3][6]. - The immune response can lead to additional symptoms such as nasal congestion and fever, especially in young children whose immune systems are still developing [3][6]. Group 2: Prevention of Colds - Common remedies like vitamin C and various juices do not effectively prevent or shorten the duration of colds; they primarily provide symptomatic relief [7]. - Effective prevention methods include: 1. Frequent hand washing to eliminate viruses from hands [8]. 2. Wearing masks in crowded or poorly ventilated spaces to block virus transmission [9]. 3. Ensuring proper ventilation in indoor spaces to dilute airborne viruses [10]. 4. Vaccination against specific pathogens that cause respiratory symptoms, such as the flu vaccine [11]. Group 3: Relief Measures for Sore Throat - While immediate relief from sore throat is not possible, several methods can provide comfort: - Drinking warm or cold beverages, such as tea with honey or lemon [12]. - Consuming cold desserts like ice cream [13]. - Sucking on hard candies for older children [14]. - Gargling with warm salt water for children aged six and above [15].

Core Points - A recent case in Henan involved a 2-year-old girl who initially showed symptoms similar to a common cold, but tragically passed away from fulminant myocarditis after her condition rapidly deteriorated [1] - Four days later, her 4-year-old brother exhibited similar symptoms and is currently in ICU after falling into a coma [1] Group 1: Understanding Fulminant Myocarditis - Fulminant myocarditis is a severe form of myocarditis characterized by rapid onset and progression, potentially leading to cardiogenic shock or sudden death [2] - Early symptoms can be misleading, resembling a common cold, but can quickly escalate to heart failure or severe arrhythmias, affecting multiple organ functions [2] Group 2: Causes of Fulminant Myocarditis - Viral infections are the primary infectious cause, with coxsackievirus, echovirus, influenza virus, and adenovirus identified as major pathogens [3] - Bacterial and parasitic infections, while less common, can also lead to the condition [5] - Non-infectious factors include autoimmune diseases, allergic reactions, toxin exposure, genetic predispositions, and unhealthy lifestyle habits [6][7][9] Group 3: Symptoms in Children - Common symptoms in children include difficulty breathing, palpitations, chest pain, fatigue, cough, fever, nausea, and dizziness [11] - Parents should be vigilant for multiple or persistent symptoms and seek medical attention promptly [13] Group 4: Prevention and Care for Children - Strengthening the child's immune system through regular routines and outdoor activities is essential [13] - Avoiding public places during flu season and maintaining distance from sick individuals can reduce infection risk [14] - Vaccination against influenza is recommended when possible [15] Group 5: Management of Myocarditis in Children - Close monitoring of symptoms and regular medical check-ups are crucial for diagnosed children [16] - Adequate rest and activity control are necessary during acute phases [17] - Medication may include antiviral, anti-inflammatory, or diuretic drugs, with strict adherence to medical guidance [19] - A balanced diet is important for recovery, with attention to salt and sugar intake [21] - Psychological support for both the child and family is vital during treatment [21]
