What is the cause of chest pain in front of the back?

Chest pain is a very common symptom. There are many reasons for chest pain, among which angina pectoris caused by coronary heart disease is the most dangerous. In the hospital, patients who come to see a doctor because of chest pain are often encountered. The following are some self-identification points of angina pectoris caused by coronary heart disease:

1. The chest pain during the sudden attack of angina pectoris has little or no warning, and during the two attacks, the patient can feel completely normal. Therefore, sudden severe chest pain can not be taken lightly, it is often an important signal of angina pectoris.

2. The position of chest pain during angina pectoris attack is in the chest. Patients' chest pain is mostly in the chest, that is, the area bounded by the front line of the left axillary and the upper edge of the chest back to the upper abdomen. The most common position is in the upper or middle part of the chest and back, and it is often difficult for patients to accurately express pain.

3. Chest pain is difficult to accurately describe the attack of angina pectoris. Patients often describe the feeling of chest compression, contraction and obstructive asphyxia, rather than real pain. However, patients are afraid to continue their activities, which is also the same feature of patients with angina pectoris.

4. Emotional or activity-induced chest pain. Labor, excitement, anger, excitement, cold, etc. It may induce angina pectoris, especially after meals, when you are still outdoors in cold or windy weather, it is more likely to cause chest pain. This is also one of the important characteristics of angina pectoris.

The onset time of chest pain is very short, usually three to five minutes, and the time is very short. It is rare for angina pectoris to last for more than half an hour, unless there is myocardial infarction.

6. Persistent chest pain. The pain symptoms of angina pectoris always occur in the same place for each patient, the duration is the same, and the nature of the pain is similar. The difference is mainly in severity. These different causes are closely related to the severity of coronary heart disease.

7. Nitroglycerin is effective. When chest pain occurs, sublingual nitroglycerin has obvious therapeutic effect on patients with angina pectoris of coronary heart disease. Generally, chest pain can be relieved within 2-3 minutes after taking medicine, which is very important in the diagnosis of angina pectoris.

In a word, angina pectoris is one of the dangerous signals of coronary heart disease, and neither doctors nor patients can treat it lightly. Once angina pectoris occurs, it means that the condition is serious. Because angina pectoris may lead to myocardial infarction, people with coronary heart disease should be familiar with the characteristics of angina pectoris and take correct preventive measures under the guidance of doctors.
