In the past 30 years, the overall mortality rate of cardiovascular diseases in mainland China has shown a rapid upward trend. In 1990 it was just 205/100,000, but in 2019 it has grown to 322/100,000.
The mortality rate per 100,000 people is 1.6 times higher than it was 30 years ago. There are even relevant data, 544,000 sudden cardiac deaths occur on the mainland every year.
What is this concept, which is equivalent to an average of every minute, one person completely bids farewell to the beautiful world due to sudden death.
In cardiovascular disease, the disease with the highest sudden death rate is "myocardial infarction", which is clinically known as myocardial infarction.
In severe cases, patients may have severe angina, difficulty breathing, and a sense of imminent death within a short period of time, and sudden death.
Therefore, for the heart attack patients who were rescued in time and took their lives from the hands of the god of death, they are undoubtedly the luckiest.
However, after the rescue of myocardial infarction, it does not mean that the days after that can sit back and relax. In fact, after a heart attack, it is likely to cause some irreversible damage to the heart, and even lay the foundation for the next heart attack.
So the question is, what damage does a heart attack cause to the heart?
1. Arrhythmia: within 1-2 weeks after the onset of myocardial infarction, nearly 75 to 95% of patients will have arrhythmias, especially within 24 hours after the onset of the disease.
The vast majority of patients have ventricular arrhythmias, especially ventricular premature beats. Some patients may also have problems such as ventricular tachycardia and ventricular fibrillation, and die as a result;
2. Heart failure: this is also one of the most common problems of myocardial infarction, and its incidence has reached about 20 to 48%, which can occur in the first few days of onset, or in the stage of pain and shock improvement.
This is so because after the myocardial infarction, the contractility of the patient's heart is significantly weakened and gradually becomes uncoordinated;
Therefore, in the first few days after the onset of the disease, acute left heart failure is most likely to occur, there are symptoms such as dyspnea, cough, irritability, inability to lie flat, etc., in extremely serious cases, the patient will even suddenly have acute pulmonary edema;
3. Heart changes: if the patient's heart valve dies due to ischemic oxygen supply, it will have a direct impact on its function, resulting in dysfunction and rupture of the heart valve.
If a large area of ischemic oxygen necrosis occurs in the ventricular wall, it will increase the pressure on the heart chambers, and the patient's heart chambers will gradually expand outwards, and then form a wall tumor of the ventricle.
Some severe patients may have serious problems such as heart perforation and heart rupture.
Among them, heart rupture is particularly terrible, which mostly occurs within 1-2 weeks after myocardial infarction, the incidence rate reaches about 3 to 13%, and patients can have problems such as cardiac insufficiency and heart failure due to heart rupture.
From the above content, it is not difficult to see that a myocardial infarction has great harm to the body, even if the patient can be rescued in time and get out of the danger of death, there may be heart failure, myocardial infarction recurrence, death and other problems in the later stage.
Therefore, in clinical view, the most important point of myocardial infarction is that everyone should learn to prevent it in life:
1. Control the development of three high diseases and coronary heart disease, and treat them with medication in strict accordance with doctors' recommendations;
2. Pay attention to life and diet adjustment, maintain light and regular meals, and regularly carry out soothing sports;
3. Pay attention to regular review, especially to measure blood pressure, blood lipids and blood sugar and other indicators;
4. Be diligent in observing physical changes, once unstable angina, angina attacks become more and more frequent, need to be checked in time;
5. Control personal emotions, pay attention to weather changes and increase or decrease clothing with the weather, avoid strenuous activities;
6, away from unhealthy bad habits, such as quitting smoking and alcohol, not staying up late, etc.
Finally, I would like to remind everyone that myocardial infarction seems to be a sudden onset of disease, but it takes a long time from healthy cardiovascular to myocardial infarction.
Therefore, from now on, we should do a good job of prevention. Especially for patients who have already developed underlying diseases, it is necessary to actively cooperate with doctors for relevant treatment and regular review.
