Sudden myocardial infarction and cough can help yourself? Don't try
Recently, "39-year-old writer Lai Bao passed away due to a sudden myocardial infarction" in the circle of friends, people once again increased their vigilance against the "invisible killer" of myocardial infarction. Although acute myocardial infarction has a rapid onset, it is not without a trace. The doctors of 120 Beijing Emergency Center will introduce some methods for everyone to catch the clues of myocardial infarction as soon as possible.
In addition, emergency doctors reminded that the best treatment time for acute myocardial infarction is only 120 minutes. If there are symptoms of chest tightness, chest pain, or even shortness of breath, dizziness, and sweating, it must be taken seriously. If you don’t get relief within 15 minutes, you should call 120 for help.
Help you catch the "clues" of myocardial infarction
Myocardial infarction is myocardial infarction. It happens suddenly and has a high mortality rate. It is the most serious disease that can happen to the heart. However, no disease occurs suddenly, and there are always some signs. How does myocardial infarction come about? Only by knowing these can we identify the disease and prevent it as soon as possible.
What are the signs of myocardial infarction? The emergency doctor suggested that when the following symptoms occur, it is recommended to call 120 to go to the hospital as soon as possible without delay or driving to the hospital by yourself.
The earliest symptom of painful myocardial infarction is pain. It usually appears in the early morning without obvious cause. At the same time, the duration of the symptom ranges from a few hours to a few days.
Whole body fever is mainly caused by the absorption of necrotic substances. Generally, fever symptoms will appear one to two days after the pain symptoms, and the duration is about one week.
Patients with nausea, vomiting, and epigastric pain may experience recurrent nausea, vomiting, and epigastric pain.
Hypotension and shock are mainly manifested as unresponsiveness, dark complexion, sweating of the forehead, neck and extremities, low skin temperature and low urine output.
Don't bear this deadly chest pain
120 Emergency doctors at the Beijing Emergency Center said that fatal chest pain includes acute myocardial infarction and unstable angina, aortic dissection, and tension pneumothorax. Acute myocardial infarction and unstable angina pectoris are difficult to distinguish based on clinical symptoms alone, and must be distinguished by electrocardiogram and myocardial enzyme examination.
If these symptoms occur, it is highly suggestive of myocardial infarction: chest pain is compressive, contracting, burning, knife-cutting, or heaviness. Generally located behind the breastbone, it can radiate to the neck, lower jaw, upper abdomen, shoulders, back or left forearm. In addition, some people have difficulty breathing, chest tightness, shortness of breath, etc., as well as restlessness, cold sweats, nausea and vomiting, palpitation and fear, feeling of dying or even black eyes, fainting, etc.
Aortic dissection: The pain is characterized by sudden pain, front and back pain, metastatic pain, the most painful at onset, and tearing pain. Blood pressure increased significantly during the attack.
Tension pneumothorax: dyspnea gradually worsens after trauma.
The characteristic of non-fatal chest pain is that it is generally not life-threatening. The chest pain is accompanied by local tenderness and acupuncture-like pain, and the pain is aggravated when turning the trunk, breathing and eating.
Sudden myocardial infarction, severe cough or cardiac arrest
Earlier, there was a hot message on the Internet about "self-help for myocardial infarction, cough hard". This life-saving post stated that "When a patient with myocardial infarction occurs, he should cough continuously, breathe deeply and cough hard, and take a few seconds every time until the ambulance rushes. It will stop until or when the pulse returns to normal." He also claims that this is because "deep breathing is to inhale oxygen into the lungs, and coughing is to squeeze the heart with this action, thereby promoting blood circulation, which may help restore normal pulse."
For patients who are alone with a heart attack, does a hard cough really work? 120 Beijing emergency doctors said that the cough resuscitation method may induce cardiac arrest!
According to reports, fatal arrhythmia is the primary cause of death from myocardial infarction. The principle of the cough resuscitation method is that at the moment when the instrument detects a cardiac arrest, coughing and squeezing the chest cavity can increase the pressure in the chest cavity in a short time, increase blood pressure, stimulate the heart, and maintain a brief wakefulness for tens of seconds.
However, it should be noted that the cough resuscitation method is only suitable for use by doctors in conscious patients in places such as cardiac catheterization rooms under monitoring conditions, and is only effective for patients with fatal arrhythmia. In reality, patients with fatal arrhythmias are often unconscious within seconds. People cannot predict when to use the cough resuscitation method, and coughing will increase the contraction of the heart, but it will increase the burden on the heart, and more serious may even cause cardiac arrest and death. Therefore, the scope of application of this cough resuscitation method is very limited, and it is not recommended for ordinary patients.
Tips: emergency treatment like sudden myocardial infarction
The rescue of patients with myocardial infarction pays attention to "every second counts". The timely delivery of medical treatment is the key, but the correct self-help of the patient is also crucial. For patients with myocardial infarction, lying still after the onset is the best self-help. During the attack, the patient will have chest tightness and shortness of breath. Therefore, stop any action that will burden the heart and call the emergency number for professional treatment as soon as possible. Do not cough forcefully to help yourself.
After the patient develops myocardial infarction, the people around must first stabilize the patient's mood, rest quietly, and avoid moving the patient. At the same time, the patient should be lying on the spot with his head sideways to keep the airway smooth and adequate blood supply to the brain. Conditions can be oxygen. At this time, remember not to give the patient medicine randomly, for example, eating nitroglycerin indiscriminately may accelerate death.
At the same time, you must call 120 immediately, and you must not carry it back, so as not to increase the burden on the heart and make the condition worse, and be ready for CPR at any time.
