Myocardial infarction is also a common disease in life, and its disability rate and fatality rate are very high.
Although its harm is particularly serious, but its occurrence is not accidental, many patients are some abnormal symptoms that existed before the onset of the disease, not found in time, so they will miss the best time for treatment.
Therefore, only when we attach great importance to this disease and understand the relevant symptoms, can we do a good job in the effective prevention and treatment of myocardial infarction, and let's take a look at the problem of myocardial infarction.
What are the signs of a heart attack in the body before it occurs?
1. Weak and tired
If, after determining that there is no exercise, no illness, no staying up late, suddenly feel very tired, and the person is in a weak state, then it is necessary to be vigilant.
Usually, this symptom occurs suddenly due to a severe obstruction of blood circulation, which can lead to myocardial infarction.
2. Heart failure
When symptoms of myocardial infarction occur, the contractility of the heart will appear uncoordinated and significantly weakened.
Therefore, in the earliest few days of the disease, there will be acute left heart failure, patients will show cough, irritability, difficulty breathing, can not lie flat and other manifestations, in severe cases, acute pulmonary edema will occur, some patients will cough up a large amount of pink foamy sputum, the later stage may cause right heart failure.
3. Arrhythmia
After extensive surveys, about 75% to 95% of patients develop symptoms of arrhythmias, and this symptom is mostly seen within 1 to 2 weeks before the onset of illness, and is most common within 24 hours.
Among patients with arrhythmias, most of them are ventricular arrhythmias, and the common symptoms of patients are ventricular premature beats, and some patients may cause sudden death due to tachycardia.
4. Pain
Pain is also one of the most prominent manifestations of myocardial infarction, usually with no obvious trigger at the time of the attack, and often occurs in a state of rest, and the site of pain is particularly similar to the nature and angina.
However, the degree of this pain is usually more severe, and it lasts for a long time, some up to several hours or days, and the symptoms are not relieved after taking nitroglycerin, and patients often show fear or near-death, irritability.
5. Shock
After a myocardial infarction, 20% of patients can be accompanied by symptoms of shock and shock, mostly within a week or hours after the onset of the disease, and patients usually present with a sudden drop in blood pressure, cold and wet skin, irritability, pallor, and even fainting.
The main reason for the shock of patients is that due to severe injury to the myocardium, the output of the left ventricle will be drastically reduced, and cardiogenic shock will occur.
It may also be due to hyperphoria due to heavy sweating or vomiting, which may lead to shock.
The above is the introduction of the signal of myocardial infarction before the onset of the disease, through the introduction of the belief that everyone has a deep understanding of the current vascular disease, then in life since the above similar situation, then we must be vigilant about the occurrence of myocardial infarction, you must go to the hospital in time, you can reduce the damage caused by myocardial infarction to the human body.
When the disease is diagnosed, it is necessary to strictly follow the doctor's instructions for regular medication, and also regular follow-up, according to the results of the examination, combined with the doctor's advice to adjust the medication plan, in addition, the patient should take a step-by-step approach every day to carry out appropriate exercise, can not rush.
