What are the characteristics of typical stable angina pain?

Stable angina pectoris generally refers to angina symptoms after fatigue. This is a common angina pectoris. The frequency of attacks is regular. Maybe once a day or once a week. The factors inducing angina pectoris are fatigue, emotional excitement, overeating, cold and so on. The nature and location of angina pectoris are relatively fixed. The duration of angina pectoris is similar. Generally speaking, after resting or applying drugs to dilate the coronary artery, the symptoms will be relieved quickly. Although the condition of stable angina pectoris is relatively stable, it is necessary to evaluate the coronary artery as soon as possible.

Stable angina pectoris is myocardial ischemia caused by fatigue, which leads to discomfort in the chest and its vicinity. Can be accompanied by cardiac insufficiency, but no cardiac necrosis. The pain characteristic of stable angina pectoris is paroxysmal chest pain. The pain is mainly located in the upper or middle part of the sternum. It can also radiate to the left shoulder and reach the ring finger and little finger inside the left arm.

Chest pain is usually compressive, sultry or contractive, and can also be manifested as burning pain. Some patients are occasionally accompanied by fear of death. During the attack, patients usually stop their original activities unconsciously until the symptoms are relieved. Angina pectoris is only caused by physical labor or emotional stimulation, such as anger, anxiety and excessive excitement. Angina attacks last about 3 to 5 minutes, usually less than half an hour. Taking nitroglycerin under the tongue can relieve the disease in a few minutes.

As far as the site of the disease is concerned, there is a sense of oppression mainly in the palm area before or after the sternum, that is, above the heart socket. The duration is usually not too long. It will be relieved in one to five minutes. May be accompanied by radiation from the left shoulder and left arm. Most pain attacks have certain incentives, which may be caused by intense physical activity or weather changes. Induced seizures are usually caused by physical labor or emotional excitement (such as anger, anxiety, excessive excitement, etc.). ). satiety, cold absorption, tachycardia, shock and other pains. It usually happens when you are tired or excited, not after a hard day's work. Typical angina pectoris often recurs under similar circumstances, but sometimes the same delivery will only cause angina pectoris in the morning instead of in the afternoon, which indicates that it is related to the change of circadian rhythm, such as the increase of sympathetic nerve excitability in the morning.
