A 25-year-old actress, why did a good man suddenly die of a heart attack? Is sudden death of myocardial infarction without warning?

Ling Meiqi, the actor of "The Little Magic Fairy of Balala", died. On this New Year's Eve,

Sleepless, she was crying by netizens and went back to save the magic fairy castle.

In In the Mood for Love, why did he die of a sudden heart attack at the age of 25? What is myocardial infarction?

Myocardial infarction is short for myocardial infarction,

It is myocardial necrosis caused by acute or persistent ischemia and hypoxia of coronary artery.

We focus on two key words: coronary artery, ischemia and hypoxia.

The coronary artery that supplies blood to the heart,

About 3.5 mm, and then through these vascular reticulation structures,

Provides nutrients and oxygen in the blood for cells in all areas of the heart.

All areas of the heart are well supplied and eat hemp.

Then the heart must be trying to send blood to other organs.

So the heart looks like a kitchen,

Cardiomyocytes are like chefs.

Cardiomyocytes in all cell areas of the heart are definitely not full, or even unable to eat.

How can myocardial cells pump blood normally when the chef has nothing to eat?

Therefore, the more serious the coronary artery blockage, the easier it is for the chef's myocardial cells to be ischemic and hypoxic.

It leads to myocardial cell death, which is what we often call myocardial necrosis.

What if it's completely blocked?

It will definitely cause large-scale necrosis and cause sudden death of myocardial infarction.

If this process develops slowly,

No myocardial necrosis, chest tightness, dyspnea, angina pectoris, shoulder pain, etc.

So these are all possible precursors of myocardial infarction, which are typical. Generally, special attention should be paid to continuous attacks for several minutes.

But there are also some atypical firsts,

For example, some unexplained epigastric pain will be caused by cell necrosis in the lower wall of the heart.

The diaphragm is stimulated by nerve, which leads to muscle tension and upper abdominal pain.

Another example is toothache and sore throat, which are acid metabolites produced by anaerobic metabolism of myocardium.

Stimulate the sympathetic afferent fibers of the heart and make the pain radiate to these parts.

Just like a water pipe, it will slowly rust and block the water supply.

It will also suddenly stop water supply for some reasons.

The most common one is: excessive emotional excitement, leading to an increase in blood pressure,

The heart rate increases and the heart suddenly runs at high load.

Causing coronary artery spasm for a short time and inducing myocardial ischemic infarction.

There is also this incident, which is rumored to be the cause of excessive drinking, like excessive emotions.

The excitability of sympathetic nerve is enhanced, and the secretion of catecholamine in the body is increased.

Blood pressure increases, heart rate increases, and cardiac afterload increases.

Moreover, alcohol can also cause central nervous paralysis and peripheral vasodilation.

Blood pressure suddenly drops and shock occurs, and coronary perfusion drops.

Simply put, the blood vessels suddenly contracted, sealing the doors and windows of the kitchen blood vessels, and the myocardial chef suffocated to death.

Alcohol can also paralyze the internal alarm system and accelerate myocardial death.

Acute common causes, as well as sudden cold stimulation, sudden illness,

Such as dehydration, potassium loss, or excessive bleeding caused by excessive exercise.

Lead to sudden heart involvement, ischemia and hypoxia, and sudden death from myocardial infarction.

Of course, most of these factors are not achieved overnight.

It is caused by the accumulation of bad habits over a period of time.

Such as staying up late for a long time, smoking too much, heavy physical and mental work, etc.

It may cause changes in the ionic environment in the body, leading to arrhythmia.

It is best to have nitroglycerin or nitrate at home.

Can be immediately used for the first aid of myocardial infarction.

Because the prime time for rescue after myocardial infarction is only about 3 hours.

Stay away from myocardial infarction, stay up as little as possible, exercise more, eat healthily, and don't drink too much.

Pay attention to hypertension, hyperlipidemia, diabetes and other diseases that are easy to increase the burden on the heart.

It is necessary to intervene and treat in time to reduce the occurrence of tragedies.
