Angina symptom assessment?

summary

Angina pectoris is a group of symptoms, which is a clinical syndrome of myocardial ischemia due to the temporary imbalance between myocardial hypoxia and oxygen supply. Myocardial ischemia may be caused by the increase of myocardial oxygen demand exceeding the blood supply capacity of the diseased coronary artery, or by the decrease of blood supply of the coronary artery, or both. It is characterized by paroxysmal chest crushing pain, which can be accompanied by other symptoms. The pain is mainly located in the posterior part of sternum, and can radiate to the precordial area and left upper limb. It often occurs in labor or emotional excitement. It can occur 3-5 minutes each time, once a few days, or several times a day, and disappear after rest or nitrate preparation. Most of the patients are over 40 years old. Fatigue, emotional excitement, satiety, cold, rainy weather and acute circulatory failure are common causes.

Angina symptom assessment?

Paroxysmal, with oppressive or constrictive feeling, the duration is usually several minutes, variant, initial or severe attack of labor angina pectoris can last for a long time, but rarely more than 30 minutes.

The most common site is behind the middle sternum or slightly to the left, or between the upper abdomen and pharynx, or between the bilateral axillary front; Pain usually radiates to the left upper limb, and a few can radiate to the mandible, mouth or back. Individual pain begins in the upper arm and then radiates to the chest.

It can relieve the pain immediately or quickly in a short time. If it takes more than 4-5 minutes, its significance is doubtful. But there are also a few severe angina attacks, the effect of nitroglycerin is not obvious.

matters needing attention

Unstable angina pectoris is similar to stable angina pectoris in pain location, nature and ECG changes during attack, but the exertional inducement of attack is not as typical as stable angina pectoris, which can be induced by rest or slight activity. New onset or obvious deterioration of exertional angina pectoris within one month also belongs to unstable angina pectoris; The pain site of myocardial infarction is similar to that of stable angina pectoris, but its nature is more severe. The duration of myocardial infarction is more than 30 minutes, which can be as long as several hours. It can be accompanied by arrhythmia, heart failure or (and) shock. Nitroglycerin can not be relieved. ECG often has a typical dynamic evolution process. Laboratory examination showed that myocardial necrosis markers increased; White blood cell count and erythrocyte sedimentation rate increased.
