The death of heart disease is very fast. You may just go out to work as usual, and suddenly feel uncomfortable. You will faint, shock and be sent to a doctor. Therefore, doctors now emphasize that chest tightness and chest pain may be heart disease, and you should remember to send them to the doctor. However, chest tightness and chest pain may also be caused by lung problems, gastroesophageal reflux, or other problems. Even some people do not know what "unknown chest tightness and chest pain" are, and they are not alert when problems occur, or they miss the golden rescue time.
How to see chest tightness and chest pain?
In order to tell the general public that chest tightness and chest pain are very serious problems, and to explain the symptoms clearly, so that people can judge at the first time, Japanese pathologist yandel wrote in "doctor, what's wrong with me?"? 》This book refers to the way to judge the chest tightness and chest pain of heart disease. The following is the excerpt from the book, hoping to let you know more about the causes of chest tightness and chest pain caused by heart disease, as well as more specific symptoms.
What is the feeling of chest discomfort caused by heart?
Chest discomfort caused by the heart is simply related to angina pectoris and even myocardial infarction. These diseases, like those mentioned above, are the causes of pain:
The blood vessels of the heart are blocked and narrowed (vascular pain)
Because of the blockage of the blood vessels in the heart, there is insufficient blood in the myocardium (pain caused by ischemia, pain caused by painful substances)
If we want to explain it in more detail, we will feel the pain in the heart when the muscles lack blood as necessary energy.
When there is an imbalance between the demand and supply of blood, the heart will feel pain.
Some people may think "I know it without saying it", but this way of thinking is very important.
"When the coronary artery narrows, it will form angina pectoris. When it is blocked, it will become myocardial infarction, and you will feel pain in your chest.". However, in practice, even if 95% of the coronary arteries are blocked, and only 5% of the space is left to supply blood, the chest does not necessarily suffer from pain.
No, when exercise = the heart is not racing, even if 95% of the end of the coronary artery (where the heart is responsible for less volume) is narrowed, sometimes it doesn't produce any symptoms. This means that even if only 5% of the gap can barely supply the oxygen and energy needed, it is enough for a calm heart.
On the other hand, when people with only 5% of the space left in the coronary artery do exercise, and the heart is beating violently... That is, when the careful muscle needs more oxygen, dull pain will appear near the heart. This is labor-related chest discomfort and labor-related chest pain, a symptom of the disease known as angina pectoris.
When the heart beats violently, it means that the heart needs oxygen and energy = the demand increases, so the body also needs to increase the supply. However, as soon as the coronary artery becomes narrower, these "additional supplies" cannot be delivered smoothly.
In addition, it is not only when the coronary artery is narrowed that the imbalance between demand and supply will be caused.
Like anemia.
When there are fewer red blood cells in the blood, the amount of oxygen carried is reduced. So in anemia, even if the coronary artery is not narrowed, the amount of oxygen sent to the heart may be insufficient. Sometimes anemia patients as long as a movement, will immediately appear chest discomfort. This means that although the "blood itself" has reached the heart, it will not get the required amount of "oxygen" because of the lack of red blood cells.
Chest discomfort caused by working angina pectoris and anemia is caused by myocardial oxygen deficiency. Therefore, it mainly belongs to visceral pain, which is the type of pain that can not be pointed out.
This kind of pain can make people feel the whole chest stuffy, feel very heavy, sometimes some people will use "burning feeling", "like being tightly grasped" and "feeling strangled". Some even say it's like "the pain of a heavy weight on your body.".
However, chest discomfort and chest pain caused by the heart are usually accompanied by radiation pain.
Chest discomfort and chest pain can radiate to the neck, chin, teeth or left shoulder. In order to transmit the stimulus to the brain, the nerve responsible for transmitting heart pain will enter the spinal cord parallel to the nerve in charge of the above parts, causing the brain to mistakenly think that "this is not a heart pain, but a jaw pain? That's why it's the pain of radiating pain. Please cheer up, brain!
In fact, some patients come to the hospital because of "jaw or tooth pain", but they are actually suffering from angina pectoris and myocardial infarction. Really, please cheer up, brain! Compared with angina pectoris, myocardial infarction is a disease in which blood vessels are completely blocked, and the symptoms of pain are more intense. Because of the characteristics of myocardial infarction and vascular pain, it is easier to use the finger to locate the pain (becoming closer to the body pain).
In many textbooks, it is recorded that "myocardial infarction has more severe pain than angina pectoris".
Although a little digressive, patients with myocardial infarction often experience "chest pain that makes people sweat". The symptom of "sweating" or "sweating" itself is very suspicious. If we find that "it's not the same as usual..." when we see a patient, the reaction of unexplained cold sweat is often a warning sign of severe diseases. In fact, it is not only the heart, but also the autonomic nervous symptoms of sweating or vomiting when there is acute ischemia or something wrong with the organs.
What is the feeling of chest discomfort caused by large blood vessels?
As for the discomfort caused by large vessels, the most important thing to recognize is aortic dissection. This is one of the four most important rule out lesions of chest pain, which can suddenly attack and bring severe pain.
Aortic dissection is a severe vascular pain caused by the rupture of the aortic wall. When the vascular wall ruptures along the aortic path (like the feeling of thin skin peeling on the inside of the vessel!) The pain will move from the top to the bottom, which is a famous pain feeling. Although some people describe this kind of pain as "tearing pain" and "like being cut by a knife", in fact, few patients will explain it in such detail... But to be honest, seeing that the patient has already suffered too much, the medical staff can intuitively think that "this situation is very important.".
There is also a disease called aortic aneurysm. This is where the inner wall of a part of the aorta becomes weak and swollen. Although the aneurysm is basically asymptomatic, it sometimes ruptures. Once the aneurysm ruptures, it will suddenly produce strong pain, and cause massive bleeding, which makes blood pressure drop rapidly. So it's best to find out early when there are no symptoms.
All of the above-mentioned diseases belong to vascular pain, which, like somatosensory pain, can indicate the location of the pain. But compared with this point, the most characteristic of them is the intense pain. Although occasionally there seems to be less painful aortic dissection, this time will make the diagnosis more difficult.
