10 Devilish Moments That Induce a Heart Attack
Emergency data from many hospitals show that during the Spring Festival, the incidence of acute myocardial infarction tends to increase significantly.
Arranging New Year's goods, overeating, and emotional agitation can easily become the "fuse" that induces myocardial infarction.
Today, Liu Jian, deputy director of the Department of Cardiovascular Medicine of Peking University People's Hospital, sorted out the ten "devil moments" of acute myocardial infarction.
Case playback:
Seventy-year-old man suffers heart attack after chest pain for 18 hours
On the morning of the first day of the new year, the whole city was still immersed in the joy of keeping the new year. The roaring ambulance broke the silence. Grandma Wang, who was busy with the festival, finally fell ill after carrying it for several days.
Looking back on the past few days, early in the morning on New Year's Eve, 71-year-old grandma Wang started to prepare for the New Year's Eve dinner, and did not take any rest during the nap every day.
In the afternoon, she was cleaning up the house when she suddenly felt a sharp pain in her chest, which made her sweat profusely.
In fact, as early as a few days ago, she started cleaning, shopping for New Year's goods, washing and washing, and was busy with chest tightness and palpitations, but she kept it from talking.
"You must be tired, just bear with it for a while, but you can't delay the New Year!" Grandma Wang passed New Year's Eve in pain.
In the early morning of the New Year's Day, Grandma Wang finally hoped that the children could go home for the Chinese 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!"
The situation was urgent, and the doctor immediately transferred Grandma Wang to the catheterization room for coronary angiography in the shortest possible time.
It was found that the anterior descending branch, an important branch of the coronary artery, was completely occluded by Grandma Wang, and a large amount of thrombus was aspirated during the operation, and the arterial blood flow finally returned to normal.
Coronary artery blockage for 6 hours
Myocardium is permanently "stiffened"
Coronary arteries are the "nutrient channels" for cardiomyocytes. It is the coronary arteries that provide nutrients to cardiomyocytes so that cardiomyocytes can work normally and the heart can continuously pump blood to all parts of the body.
Within 20 minutes of coronary occlusion, the ischemic myocardium can be repaired if it can get blood supply again; if it is occluded for more than 20 minutes, the ischemic myocardium begins to undergo irreversible necrosis, and it cannot be repaired even if it receives blood again.
The blood flow was restored within 3 hours of occlusion, and the infarcted myocardial area was reduced by 20% compared with the restoration of blood flow after more than 3 hours.
If the restoration of blood flow is delayed until 6 hours later, the cardiomyocytes nourished by the blocked vessel will undergo permanent necrosis.
The necrotic cardiomyocytes will regenerate into fibrous connective tissue, which is very tough, but cannot contract, and the contractility of the myocardium will decrease, which will seriously affect the function of the heart, and the health and even life of the patient will be affected.
Time is life, time is heart muscle!
There are ten "devil moments" in acute myocardial infarction
If you eat too much, in order to digest the food, the blood will be transferred to the gastrointestinal tract, and the blood supply to the heart will be relatively reduced, thereby aggravating myocardial ischemia; if you eat too much oil and eat too much fat, it will also promote Thrombosis, causing myocardial infarction; excessive drinking can cause brain excitement, heart rate, blood pressure, and can induce arrhythmia.
It is recommended that you have seven full meals per meal, a light diet, and patients with coronary heart disease and middle-aged and elderly people should not drink alcohol.
Forced defecation requires holding your breath during forced defecation, the abdominal pressure will increase, and the blood pressure will rise rapidly, which will increase the burden on the heart, induce angina pectoris, myocardial infarction and malignant arrhythmia, and may cause sudden death in severe cases.
It is recommended not to exert too much force during defecation. When the defecation is not smooth, you can use Kaisailu to assist in defecation. You should also eat more fresh fruits, vegetables and whole grains rich in dietary fiber at ordinary times.
When taking a hot bath, the blood vessels of the whole body expand, and staying in a closed and hypoxic environment for a long time can easily cause brain and heart ischemia.
It is recommended not to take a bath with a full meal or hunger. The temperature of the bath water should be equal to the body temperature, and the time should not be too long. It is best for people who are older or have limited mobility to do it with the help of others.
Vigorous exercise will force the heart to double the work, strong contraction and relaxation, resulting in a sudden increase in blood pressure, rapid heart rate, myocardial hypoxia, and even induce myocardial infarction.
It is recommended to do warm-up exercises, preferably brisk walking, jogging and other mild aerobic exercise, the elderly and those with poor heart should avoid participating in competitive sports.
If you experience chest tightness, shortness of breath and other discomfort during exercise, you should sit down and rest immediately.
When excessive sadness and sadness cannot be resolved, the sympathetic nervous system will secrete a large amount of hormones, which accelerate the heartbeat, constrict the arteries, reduce the pumping function of the heart, and then cause symptoms such as chest pain, shortness of breath and shock.
It is recommended to maintain a peaceful mind and not be overly pessimistic and anxious.
Excessive stress, continuous overtime and long-term stress, the sympathetic nervous system will be in a state of excitement for a long time, resulting in excessive burden on the heart, which may lead to heart disease.
It is recommended to rest in time, combine work and rest, avoid staying up late and work overtime continuously, and learn to release stress and relax.
Emotional people are often sedentary when watching TV, playing cards, or playing chess. If they are suddenly excited, blood pressure will soar, heart rate will increase, and it is easy to induce myocardial ischemia.
It is recommended that everyone watch TV, play cards, and play chess for too long, and get up and move around appropriately to avoid prolonged sedentary and emotional agitation.
Get up too fast in the morning, wake up from the "semi-sleep" state, breathing and heartbeat speed up, blood flow speed up.
At this time, the cardiovascular test is relatively large, and cardiac events are prone to occur.
It is recommended that when you wake up in the morning, move your limbs in bed and then sit up slowly.
Snoring and sleeping "snoring" may be a manifestation of sleep apnea, a disease that occurs repeatedly during sleep apnea, which can lead to acute myocardial ischemia at night and, in severe cases, acute myocardial infarction.
It is recommended that people with severe sleep snoring should be examined and treated to rule out the risk.
Sudden changes in temperature and low temperatures can easily increase the possibility of angina pectoris, myocardial infarction and sudden death.
Generally speaking, the peak period of sudden death is from November to March of the next year, but in summer, the temperature of the air conditioner is too low, and the temperature difference between indoor and outdoor is large, which is also prone to heart disease.
It is recommended that you should keep warm when going out in winter, and the air conditioner should not be adjusted too low in summer to minimize fluctuations in blood pressure.
Just a reminder:
Myocardial infarction will say hello a day or two in advance
In addition to being alert to the top ten "Devil Moments", you must also remember to seek medical attention in time if you find chest pains!
Clinically, 50 to 80% of patients with acute myocardial infarction have early warning signs one to two days before the onset of the disease, and chest pain is an important manifestation.
Chest pain is an important symptom of an acute myocardial infarction, but not all acute myocardial infarctions present with chest pain, and pain may also occur in other areas such as the shoulders, arms, neck, back, upper abdomen, or jaw.
Moreover, the nature of pain is also very diverse, such as pressure, tightening, burning, squeezing discomfort, tearing, dull pain, and even indescribable discomfort.
In addition, patients may be accompanied by symptoms such as sweating, palpitation, chest tightness, shortness of breath, difficulty breathing, collapse, and a sense of impending death.
Patients should call emergency numbers immediately if they experience acute chest pain or similar symptoms.
Although chest pain does not mean the occurrence of acute myocardial infarction, early diagnosis or exclusion of life-threatening causes can lead to early identification or exclusion of life-threatening causes. The earlier treatment, the more hope of survival.
