In daily life, we sometimes hear some rumors about first aid, such as when a heart attack occurs, you can cough hard to save yourself. However, is this statement really true?Doctors remind us that knowing this knowledge can save lives at critical moments.
Myocardial infarction is avascular necrosis of the myocardium due to blockage of the coronary arteries. When the blood supply to the heart muscle is insufficient, the heart muscle cannot get enough oxygen and nutrients, which leads to myocardial necrosis.
According to the "China Cardiovascular Health and Disease Report" released in 2022, the number of cardiovascular diseases in China in 2022 is about 3300 million, including 13 million strokes and 11.39 million coronary heart diseases. It is worth mentioning that among the many cardiovascular and cerebrovascular diseases, there are 1 million patients with sudden myocardial infarction in China, and the number of deaths even exceeds the total number of deaths from all tumors.
Pain:The severity is severe, the duration is longer, up to several hours or even longer, and it is not relieved by rest and nitroglycerin tablets. People are often restless, sweating, fearful, or have a sense of impending death.
Systemic symptoms:There is fever, tachycardia, leukocytosis, and erythrocyte sedimentation rate. It usually occurs 24 to 48 hours after the onset of pain, and the degree is often positively correlated with the extent of infarction, and the temperature is generally around 38 and rarely exceeds 39 for about 1 week.
Gastrointestinal symptoms:May be accompanied by frequent nausea, vomiting, and epigastric pain. It is related to the stimulation of the vagus nerve by necrotic myocardium, the decrease of cardiac output, and the lack of tissue perfusion.
Arrhythmias:Ventricular arrhythmias are the most common, premature ventricular contractions are the most common, ventricular flutter and ventricular fibrillation can cause sudden death, and atrioventricular block is also common, mostly occurring within hours or days after onset.
Hypotension and shock:A drop in blood pressure during painful phases is common and not necessarily shock. If the pain is relieved and the systolic blood pressure is still below 80mmHg, the patient is irritable, pale, clammy and cold, has a thin and rapid pulse, sweats profusely, decreased urine output (<20ml h), is unconscious, and even fainting, it is a sign of shock.
Myocardial infarction is a clinical syndrome caused by insufficient blood supply to myocardium, acute myocardial ischemia and hypoxia, and is one of the common cardiovascular diseases, often life-threatening. When a myocardial infarction occurs, the body's oxygen consumption should be reduced as much as possible to reduce the burden on the heart to control the condition and wait for rescue.
However, some people cough vigorously during a myocardial infarction, believing that they can eliminate sputum and foreign bodies and relieve symptoms. But in reality, this practice is not scientific. Coughing vigorously will significantly increase physical exertion, cause an increase in oxygen consumption, and easily aggravate myocardial ischemia and necrosis, which not only does not play a role in self-help, but may also aggravate the condition.
Therefore, when a sudden myocardial infarction occurs, you should immediately stop your activities, rest on the spot, and take nitroglycerin and other drugs in time to dilate blood vessels, increase the oxygen supply to the myocardium, and relieve pain. At the same time, excessive exertion and emotional agitation should be avoided, and it should be quiet and relaxed to reduce myocardial oxygen consumption. If the patient has symptoms such as difficulty breathing, worsening chest pain, and sweating, they should immediately call the emergency service** and wait for the arrival of medical personnel. While waiting for rescue, the patient should remain calm and avoid moving as much as possible to avoid aggravating the condition.
Sudden heart attack is a common emergency in our daily life, and knowing how to respond to a heart attack correctly is essential to protect life.
1.Stay calm: Try to stay calm and don't panic. Panic may cause the heart to beat faster and worsen the condition.
2.Rest: Immediately stop ongoing activities, try to be quiet, and avoid overexertion.
3.Take fast-acting heart-saving pills: If you usually have a history of coronary heart disease, you can immediately take first-aid drugs such as fast-acting heart-saving pills. But if you don't have a medical history or are not familiar with the drug, don't take it casually.
4.Seek help: If the situation is too severe to cope with on your own, call emergency services** or seek help from someone around you.
1.Maintain a healthy lifestyle: Eat right, control your weight, avoid overexertion, and get enough sleep.
2.Control risk factors: such as hypertension, hyperlipidemia, diabetes and other chronic diseases, should be actively controlled.
3.Regular medical check-ups: Conduct regular physical check-ups to detect potential health problems in a timely manner.
In short, understanding the self-help methods and preventive measures for sudden myocardial infarction is very important to protect life safety. In daily life, we should pay attention to our physical condition, maintain a healthy lifestyle, and prevent the occurrence of myocardial infarction.
