7 warning signs of myocardial infarction and 5 prevention strategies

Figures from the British Heart Foundation confirm a significant increase in deaths from coronary heart disease in January.

According to a University of Colorado study, January is the month most people die of heart disease.

A 2012 Harvard study found that “bad cholesterol” and triglycerides, which are important causes of cardiovascular and cerebrovascular disease, hit highs in January.

Harbin Center for Disease Control and Prevention found that when the temperature was below -19 ℃, the daily excess death of coronary heart disease and cerebral infarction showed statistical significance.

The risk of myocardial infarction increased by 2% when the temperature decreased by 1 ℃

Researchers at the London School of Hygiene and Tropical Medicine found that for every 1C drop in temperature, the risk of a heart attack increased by 2 per cent. 75, 84 years old people with coronary heart disease are more vulnerable.

In winter, people’s physiological function is relatively slow, and they are often in a state of stress. Cold stimulation, the human body peripheral blood vessels will be in a constrictive state, resulting in increased arterial pressure, myocardial oxygen consumption increased, increasing the burden on the heart.

Especially suddenly from the heating room to the outdoor, the blood vessel is stimulated by cold air, easy to constrict suddenly, cause the blood flow supply to interrupt or the blood vessel to block, cause the myocardial infarction or the cerebral apoplexy.

Therefore, the winter should always pay attention to changes in the weather, timely addition of clothing. It is best to wear a mask when you go out to avoid brisk walking in the wind. Do not open the door and window in the room too big, in case cold air stimulates heart blood vessel.

In addition, the cold weather, people less outdoor sports, but also a preference for high-fat food.

Eat more, consume less, resulting in energy intake and metabolic imbalance, increased blood viscosity, slow blood circulation, easy to form thrombus, leading to myocardial infarction.

7 signals before the onset of myocardial infarction

The onset of acute myocardial infarction is sudden, but more than 50% of patients have some warning signs before the onset of myocardial infarction.

Chest pain, chest tightness.

Sudden severe chest pain or chest suffocation, or pain longer than 15 minutes, may be a signal of myocardial infarction.

Panicking and shortness of breath.

Pain in chest, back, shoulders, neck and arms.

The onset of pain is often characterized by a pain in the neck one day and a pain in the jaw the next day, or a pain one day and no pain the next day. The appearance of this transfer of pain, we should pay attention to.


Patients with obesity, high altitude and no epigastric discomfort should be on high alert for heart problems if they have a stomach ache or a burning sensation in their stomachs.


A very short period of toothache usually lasting about three minutes and recurring within a week may be a sign of a heart attack that requires attention.

Anxiety and insomnia.

Unexplained anxiety, a sudden and unannounced awakening in the middle of the night, or an unexplained sense of fear may be a sign of a heart attack.

Increased heartbeat.

If, without any inducement, you suddenly find yourself beating faster for no reason at all, lasting between 1 minute and 10 minutes, it may be a sign of a heart attack.

Do 5 points to prevent Myocardial Infarction

The study found that 90 per cent of heart attacks are preventable.

Don’t eat too much.

Eat 70% of meals, and control fat, animal viscera and other high-triglyceride, high-cholesterol foods.

If after full meal often appears chest frowsty, chest pain, heart rate is accelerated wait for unwell, need to remove heart problem to the hospital in time.

Exercise according to one’s ability.

Exercise heart rate should not exceed the target rate, exercise time should not be too long, about half an hour is appropriate.

Timely release of pressure.

Give vent to bad factors such as troubles and grievances in a timely manner. When you are nervous, stand up naturally, close your eyes, and take a deep breath to help relax your body and mind.

In the morning, the blood is thicker and more likely to embolize. After getting up in the morning, it is best to move gently and slowly, and to make up for the water in a timely manner.

Keep warm.

When out, focus on the head, hands, feet to keep warm. After returning to the room slowly off clothes and hats, as far as possible to reduce fluctuations in blood pressure.

Myocardial infarction rescue gold 4 minutes

Serious myocardial infarction is very easy to cause cardiac arrest, cardiac arrest after the 4 minutes is the prime time for first aid.

If the patient can be rescued within this period of time, the risk of death can be reduced rapidly. Otherwise, even if life is saved, the patient will suffer irreversible brain damage due to prolonged lack of oxygen to the brain.

  • First call first aid.
  • Artificial cardiopulmonary resuscitation (CPR) was performed in those with conditions.
  • Sublingual administration of 1 tablet of nitroglycerin.

Nitroglycerin is the most effective drug for relieving chest pain. When the lesion is not serious, the chest pain can be alleviated about 5 minutes after taking a tablet. If you don’t get any relief from taking 3 tablets, stop taking them and seek medical advice immediately.
