Emergency data from hospitals showed that the incidence rate of acute myocardial infarction increased significantly during the Spring Festival. Running new year goods, overeating and emotional excitement can easily become the "fuse" of myocardial infarction. Today, Liu Jian, deputy chief physician of cardiovascular department of Peking University People's Hospital, sorted out the ten "devil moments" of acute myocardial infarction.

Chest pain for 18 hours, 70 year old man busy with myocardial infarction
On the morning of the first day of the lunar new year, the whole city was still immersed in the joy of watching the new year, and the roaring ambulance broke the silence. Grandma Wang, who was busy celebrating the festival, finally fell ill a few days later.
Looking back on these days, 71 year old grandma Wang began to celebrate the new year's Eve early in the morning of the 31st day of the lunar new year, and didn't take a nap every day. In the afternoon, when she was cleaning the house, she suddenly felt a sharp pain in her chest and sweating all over her head. In fact, as early as a few days ago, she began to clean up and buy new year goods. She was busy washing and washing, sometimes with chest tightness and palpitations, but she never said anything.
"You must be tired. Bear it for a while. You can't miss the New Year!" Grandma Wang spent new year's Eve in pain.
Early in the morning on the first day of the new year, Grandma Wang finally expected her child to go home for the new year, but her chest pain gradually worsened. At the insistence of the children, Grandma Wang was rushed to the emergency center of Peking University People's Hospital by ambulance.
"Chest pain for 18 hours, extensive anterior myocardial infarction!"
In case of emergency, the doctor immediately transferred Grandma Wang to the catheter room for coronary angiography in the shortest time. The results showed that the anterior descending branch, an important branch of Grandma Wang's coronary artery, was completely occluded, a large amount of thrombus was sucked out during the operation, and the arterial blood flow finally returned to normal.
Coronary artery occlusion for 6 hours
Permanent "rigidity" of myocardium
Coronary artery is the "nutrient channel" of myocardial cells. It is the heart muscle that can continuously deliver nutrients to all parts of the heart and provide a source of blood to the coronary cells of the body.
Within 20 minutes of coronary artery occlusion, the ischemic myocardium can be repaired if it can be supplied with blood again. If the occlusion lasts for more than 20 minutes, the ischemic cardiomyocytes will begin to have irreversible necrosis, which cannot be repaired even if the blood is supplied again. The blood flow recovered within 3 hours after occlusion, and the infarcted myocardial area decreased by 20 percent compared with that after 3 hours. If the blood flow is delayed for 6 hours, the myocardial cells nourished by the blocked blood vessels will die permanently.
Necrotic cardiomyocytes will regenerate fibrous connective tissue. Fibrous connective tissue is tough but can not contract. Myocardial contractility decreases, which seriously affects heart function, health and even the life of patients.
Time is life, time is heart!
There are ten "devil moments" in acute myocardial infarction
If you overeat and eat too much, in order to digest food, the blood will be transferred to the gastrointestinal tract, and the blood supply to the heart will be relatively reduced, thus aggravating myocardial ischemia; If you eat too much fat, eating too much fat will also promote thrombosis and cause myocardial infarction. Excessive drinking will excite the brain, increase heart rate and blood pressure, and induce arrhythmia.
It is recommended that everyone eat seven full, eat a light diet, and do not drink for patients with coronary heart disease and the middle-aged and elderly.
Hold your breath when defecating forcibly. The increase of abdominal pressure and blood pressure will increase the burden on the heart, induce angina pectoris, myocardial infarction and malignant arrhythmia, and may lead to sudden death in severe cases.
It is recommended not to use too much force when defecating. When defecation is not smooth, you can use kesselu to help defecate. Usually eat more fresh fruits and vegetables and coarse grains rich in dietary fiber.
When taking a hot bath, the blood vessels of the whole body expand and stay in a closed hypoxic environment for a long time, which is easy to cause cerebral and cardiac ischemia.
It is recommended not to take a bath when you are full or hungry. The bath temperature should be equal to your body temperature, and the time should not be too long. Elderly or people using mobility
It is suggested to do warm-up exercise well. It is best to do light aerobic exercise such as fast walking and jogging. The elderly and people with bad heart should avoid participating in competitive sports. If chest tightness, shortness of breath and other discomfort occur during exercise, sit down and rest immediately.
When excessive sadness cannot be resolved, the sympathetic nervous system will secrete a large number of hormones, which will accelerate the beating of the heart, contract the arteries, reduce the blood pumping function of the heart, and then cause chest pain, shortness of breath, shock and other symptoms.
It is suggested to maintain a calm state of mind and avoid excessive pessimism and anxiety.
Excessive pressure, continuous overtime, long-term excessive pressure, the sympathetic nervous system will be in a state of excitement for a long time, resulting in excessive burden on the heart, which is easy to lead to heart disease.
It is suggested to take a timely rest, combine work and rest, avoid staying up late and working overtime, learn to release pressure and relax.
Emotional watching TV, playing cards and chess, often sedentary. If you are suddenly excited, your blood pressure will soar all the way, your heart rate will increase rapidly, and it is easy to induce myocardial ischemia.
It is recommended not to spend too much time watching TV, playing cards and playing chess. Get up and exercise appropriately to avoid sitting for a long time and getting excited.
Wake up too fast in the morning, wake up from the "semi dormant" state, breathe faster, heartbeat faster and blood flow faster. At this time, the cardiovascular test is relatively large, and cardiac events are prone to occur.
I suggest you get up in the morning, move your limbs in bed, and then sit up slowly.
Snoring "snoring" may be a manifestation of sleep apnea. This kind of exercise repeatedly appears apnea during sleep, which can lead to acute myocardial ischemia at night and acute myocardial infarction in severe cases.
It is suggested that people with serious sleep snoring should be examined and treated to eliminate the risk.
Temperature mutation and hypothermia are easy to aggravate the possibility of angina pectoris, myocardial infarction and sudden death. Generally speaking, the peak of sudden death is from November to march of the next year, but when the air conditioning temperature is too low in summer and the temperature difference between indoor and outdoor is large, it is easy to cause heart disease.
It is recommended to keep warm when going out in winter. Don't turn the air conditioner too low in summer to minimize blood pressure fluctuations.
