Understanding Myocardial Infarction: Causes, Symptoms, and Prevention

When playing poker, there is a game called “Heart Attack”, which is that several people hold the same number of covered cards in their hands at the same time, and then turn over the cards at the same time round by round. If someone turns over the same number, To play cards, you have to clap the cards with your palms and shout “Heart disease”! (This game was quite popular in my era, but people after 2000 may have never heard of it🤣)

In short, when playing this game, you may experience cold sweats and difficulty breathing due to being too nervous. These symptoms are very similar to those of a heart attack, hence the name. And what exactly is what we commonly call a “heart attack”?

What is a myocardial infarction? How do you recognize it?

It refers to the stenosis or obstruction of the coronary arteries of the heart due to arteriosclerosis, which interrupts the blood and oxygen supply to the heart muscles, causing damage or necrosis of the myocardial tissue, which results in poor cardiac contraction function, leading to heart failure or arrhythmia, which is serious. Sometimes, people may fall into coma, shock, or even die suddenly.

The symptoms of myocardial infarction may not be the same for everyone, and not all symptoms may be present. Common symptoms:

Chest pain, chest tightness, feeling of being squeezed in the chest, burning sensation in the chest, chest pain that spreads to the shoulders, neck, upper arm (especially the left hand), jaw, shortness of breath or difficulty, dizziness, lightheadedness, dark vision, nausea and vomiting, Night sweats

Usually these symptoms will last for at least 2-5 minutes, and some people may even last for 30 minutes or relapse repeatedly. If you observe that a relative or friend around you has the above symptoms, you should advise him or her to go to the hospital for a more detailed examination. After all, Be careful to make a thousand-year ship.

What are the common causes?

In addition to congenital heredity, the causes of coronary atherosclerosis (especially the older you are, the more likely it is to occur, men are older than 45 years old; women are older than 55 years old, the chance of the disease will increase in women, especially after menopause), what we should pay attention to is the acquired lifestyle. state. After all, we can’t control congenital inheritance, so we should have a good understanding of the following risk factors, actively control them, and pay attention to improvements🙌

If you have metabolic syndrome, including:

Hypertensive patients: 2.5 times more likely to suffer from heart disease than the average personHyperlipidemia patients: Easily develop arteriosclerosis and block blood vesselsdiabetics: 2 times more likely to suffer from heart disease than the average personObese people: prone to the above diseases

If you have bad living habits, they include:

smokes: Nicotine and tar in traditional cigarettes, as well as flavors and chemicals in e-cigarettes, can damage the cardiovascular system; nicotine increases heart rate, blood pressure, and stimulates myocardial contraction; tar causes inflammation, damage to vascular endothelial cells, and promotes thrombosis; e-cigarettes produce The aerosols and smoke will damage cardiovascular endothelial cells and reduce the blood coagulation speed.Smoking increases your risk of heart disease by 2.5 timesToo much stress, excessive fatigue, long-term insomnia: When you are under too much pressure, stay up late for a long time and are tired for a long time, the adrenal glands will secrete the stress hormone “cortisol”.For people, the secretion of an appropriate amount of cortisol is necessary and healthy, because cortisol can promote blood circulation in the human body and increase the body’s energy. However, if it is secreted excessively for a long time, it will not only cause your spirit to remain in a tense state, but also It will suppress the function of the immune system, preventing immune system cells from communicating information about attacking invaders, easily causing chronic diseases, and increasing the risk of cardiovascular disease.

Preventing Myocardial Infarction: What You Can Do

The first thing to do – if you smoke,Quit smoking! >>> This may sound like common sense, but it is a scientifically proven effect.Maintain stable mood and good sleep quality >>> This sometimes has something to do with personality and the work environment. In the long run, it may accumulate and cause the walls of blood vessels and arteries to thicken and harden. The interior of the blood vessels will gradually become blocked, resulting in a lack of blood circulation and causing angina pectoris. I feel that I am a high-risk person. After all, the work pressure is quite high, so I often have insomnia. Even if I fall asleep, I can’t sleep well. I still feel tired after getting up. This solution… It seems that the only solution is to resign. ಠ_ಠ…avoid obesity >>> Obesity is a very important risk factor for myocardial infarction. If you look at your body mass index (BMI), you need to keep it between 18.5 and 24. Here is a computer for you to do the math: Avoid excessive temperature differences >>> Winter is coming again. Some elders like to take very hot baths. We must pay more attention to this on behalf of the elders, because when the temperature difference is too large, it is easy to cause rapid contraction of blood vessels, causing local blood vessel pressure to increase too much. Causes vascular plaque rupture, causing myocardial infarction.moderate exercise >>>Attention! It’s not that the more intense the exercise, the better it can prevent cardiovascular disease! According to the recommendations of the American College of Cardiology, 150 minutes of moderate-intensity exercise* per week, or 75 minutes of high-intensity exercise* per week, plus muscle-strengthening exercises (such as doing half-squats with the back of a chair) twice a week is enough. If you have already had a myocardial infarction, it is recommended to consult the doctor about the most appropriate exercise pattern, and do not force yourself to perform overloading exercises in pursuit of recovery.

Will myocardial infarction be cured?

Finally, let’s talk about if a myocardial infarction occurs but is well treated, will it relapse? Can it fully recover?

The answer is: relapse is possible. Because even if a heart stent is installed and drug treatment is used to make your blood vessels unblocked again, this is actually a temporary solution rather than a permanent solution, because the underlying causes of blood vessel obstruction, such as smoking, stress, high blood pressure, etc., have not disappeared.

Therefore, if you can continue to take medication, continue to follow up, and improve your bad lifestyle after treatment, you are very likely to be able to maintain your health! (Note that this is maintenance, not recovery!!)

However, if you are treated well and then start smoking, staying up late and not exercising again, you are likely to fall into the vicious cycle of illness and treatment again. And if you have had acute myocardial infarction, about 20% to 40% will leave sequelae of heart failure. Once formed, Heart failure, the 5-year mortality rate is as high as 50%. So please be sure to return for regular check-ups and maintain exercise habits.

The road to health is to receive treatment for myocardial infarction, follow up on medication and improve bad living habits.

*Definition of exercise intensity as defined by the National Health Service of the Ministry of Health and Welfare:

Moderate-intensity exercise: You can still have a smooth conversation if you continue to do it for more than 10 minutes, but you can’t sing. This type of activity will make people feel a little tired, their breathing and heartbeat will be faster than usual, and they will also sweat a little. When engaging in high-intensity exercise for more than 10 minutes, you will not be able to talk easily to others while moving. This type of activity can make your body feel tired, your breathing and heartbeat much faster than usual, and you may sweat a lot.
