It's angina pectoris

summary

There are two types of angina pectoris: stable angina pectoris and unstable angina pectoris. Stable angina pectoris is a clinical syndrome of acute and temporary myocardial ischemia and hypoxia caused by the increase of myocardial load on the basis of coronary artery stenosis. Its typical feature is paroxysmal chest crushing pain, mainly located behind the chest, which can radiate to the precordial region and the ulnar side of the left upper limb. It often occurs when the labor load increases. It lasts for several minutes and disappears after rest or taking medicine.

It's angina pectoris

First, unstable angina pectoris is due to the rupture of atherosclerotic plaque, accompanied by varying degrees of surface thrombosis. And a group of clinical symptoms caused by distal vascular embolism. At present, except for stable exertional angina pectoris, ischemic angina pectoris is collectively referred to as unstable angina pectoris. Stable angina pectoris is also known as exertional angina pectoris. Under normal circumstances, the coronary artery has great reserve power.

Second: its blood flow can be adjusted with the needs of the body, but once the heart load increases, myocardial oxygen consumption increases, the demand for blood perfusion increases, the coronary artery can not supply in time, it can cause angina pectoris. The main pain site of stable angina pectoris is behind the middle and upper part of sternum, which can spread to the precordial area with unclear boundary. It radiates to the left shoulder and left arm, reaching the little finger or ring finger. Or to the neck, pharynx or mandible.

Third: the attack of patients is often oppressive, oppressive, constrictive and burning, but it is not sharp, unlike acupuncture or knife cutting, occasionally accompanied by a sense of near death, the inducement is probably physical labor, emotional excitement, satiety, cold, smoking, tachycardia, shock, etc. The duration of pain is gradually aggravating, gradually disappear within 3 ~ 5 minutes, can occur once a few days or weeks, can also attack many times a day.

matters needing attention

So the symptom of heartache when breathing is not necessarily angina pectoris. If you want to accurately identify the cause, you also need to go to the regular large hospital for a series of corresponding examination. If angina pectoris is suspected, cardiac X-ray or ECG examination is recommended. In addition, radionuclide examination has a certain diagnostic value for myocardial ischemia. Coronary angiography, which can confirm angina. I wish you good health!
