Recently, Quark App and the China Cardiovascular Health Alliance jointly launched the topic of "Heart Care and Life Protection" Myocardial Infarction Treatment Day, to enhance young people's awareness of the severity of myocardial infarction and its prevention and treatment through symptom encyclopedia, popular science videos, data reports, etc. In this year's special topic of myocardial infarction treatment day, users can search for "myocardial infarction" in Quark App to learn about the knowledge of myocardial infarction prevention and first aid. Kwak worked with Professor Huo Yong, the chief physician of cardiology department of Peking University First Hospital and the chairman of the expert committee of China Chest Pain Center, to create a popular science message, telling about high-risk behaviors and prevention methods that induce sudden death of young people in a scene based way. Professor Luo Suxin, member of the Standing Committee of the Special Committee of Internal Medicine of the Chinese Medical Association and member of the Executive Committee of the China Chest Pain Center, also shared the causes and symptoms of the rejuvenation of myocardial infarction in the form of popular science videos, and emphasized practical first aid knowledge, such as "in case of myocardial infarction, you need to call 120 emergency numbers at the first time to fight for golden rescue time". On the day of myocardial infarction treatment, Professor Huo Yong, the chief physician of cardiology department of Peking University First Hospital and the chairman of expert committee of China Chest Pain Center, delivered a keynote speech on the "1120 Myocardial Infarction Treatment Day" jointly sponsored by the Cardiovascular Health Alliance, the China Association of Physicians, the China Chest Pain Center Alliance, and the Suzhou Industrial Park Cardiovascular Health Research Institute, For the industry experts and patients, we reviewed the development of 1120 Myocardial Infarction Treatment Day in the past eight years and the good model of multi support, and showed the popular science terms and special activities jointly built by Xinmeng and Quark in the cardiovascular field, calling on the public to strengthen their awareness of acute myocardial infarction. The data shows that among the users searching for myocardial infarction, young people aged 18 to 24 account for the highest proportion, and the demand for searching for myocardial infarction is the largest at 3 a.m. every day. Among the knowledge related to myocardial infarction, "What are the symptoms before myocardial infarction", "How to give first aid in case of myocardial infarction" and "How to prevent myocardial infarction" are most concerned by users. The data points out that the induction of myocardial infarction is closely related to environmental factors, including the eating habits, working environment and climate in the living area. Among them, the rapid change of climate is the key to affect the occurrence of myocardial infarction. In winter and autumn, more people search for MI related knowledge than in spring and summer. Dong Peng, director of the Department of Cardiovascular Medicine of the Affiliated Hospital of Hangzhou Normal University, believes that young people's high attention to myocardial infarction is related to the increasingly younger onset of myocardial infarction. Young people may have more dangerous heart attacks than the elderly. Obesity, diabetes, hypertension, hyperlipidemia and smoking are the main risk factors in young patients with myocardial infarction. In the past two years, Quark App, together with famous medical experts in various disciplines, has gathered popular science images, practical tools, video materials, interesting articles, etc. on common health problems and symptoms to help users efficiently obtain health information. At the same time, relying on=intelligent retrieval technology and medical knowledge atlas, create two intelligent interactive searches, namely "human model aided search" and "intelligent screening", and innovate the health search experience, so that users can ask easily and see at ease. At present, Quark App has served tens of millions of medical and health users in total, and cooperated with hundreds of top authoritative experts and associations to create a Quark Health Encyclopedia and provide authoritative and reliable medical science knowledge.
