From:Beijing Municipal Health Commission

On January 13, 2024, the emergency team of Zhu Tuanbiao, Ningping, and Zhao Feng from the Dongcheng Emergency Center Station, encountered passers-by who intercepted the ambulance to ask for help after completing a daily first aid mission. The person asking for help slapped the vehicle window and shouted: "There is a person lying on the road over there and can't move!" The crew immediately ran to the patient with medical equipment and found that the patient's limbs were weak and the face was pale. He was suffering from obvious chest pain. After on-site examination, the initial diagnosis given by the emergency doctor was acute extensive anterior wall myocardial infarction. The crew contacted the family members according to the patient's information, and at the same time urgently contacted the 120 dispatch and command center. They established a green rescue channel successfully, and quickly sent the patient to a hospital with treatment capabilities. According to a follow-up call, the patient's condition was now stable after stent implantation surgery. His vital signs are now stable and he is gradually recovering. After being discharged from the hospital, the patient's family came to the Dongcheng Emergency Center Station to express their sincere gratitude to the crew.

A sudden myocardial infarction is life-threatening. Once early warning signs are found, timely attention and treatment should be provided. Some of the signs are easy to be ignored, including the feeling of being wrapped with tape on the chest or the feeling of restraint, hearing loss and buzzing in both ears, toothache, headache, periumbilical pain, tingling pain in the soles of the feet, soreness, swelling or pain in the left shoulder blade, left upper limb or left leg, long-term dizziness or sudden fatigue and drowsiness, and etc. When the above situation occurs, it is necessary to pay attention and take medical examination as soon as possible.

Here are some tips from Beijing 120. When acute symptoms such as chest pain and tightness accompanied by profuse sweating, or severe squeezing pain in the retrosternal or precordial area occur at home, it is necessary to stay in bed, keep quiet, and take nitroglycerin under the tongue or inhale nitroglycerin by spray, and dial 120 and seek professional first aid immediately at the same time.
