What causes sudden chest pain? Sudden chest pain is most likely caused by angina. Angina pectoris is a clinical syndrome with paroxysmal chest pain or chest discomfort as the main manifestation caused by insufficient coronary blood supply, acute and temporary myocardial ischemia and hypoxia.

The direct cause of angina pectoris is insufficient blood supply to the myocardium. The myocardial insufficiency is mainly caused by coronary heart disease. Sometimes, other types of heart disease or uncontrolled high blood pressure can cause angina. If fat continues to accumulate in the blood vessels, plaques will form. If plaque occurs in the coronary arteries, it will cause them to narrow, further reducing their blood supply to the myocardium, leading to coronary heart disease. The process in which fat accumulates in the coronary arteries and gradually forms plaques is called coronary artery sclerosis. Some plaques are hard and stable, which can cause narrowing and hardening of the coronary arteries themselves. Other plaques are softer and break apart easily to form blood clots. The accumulation of this plaque on the inner wall of the coronary artery can cause angina in the following two ways: ① The lumen of the coronary artery narrows at a fixed position, which greatly reduces the blood flow through it; ② The formed blood clot partially or completely blocks the coronary artery.

Angina pectoris is often manifested as dull pain, squeezing pain, or tightness behind the sternum or in the throat. Some patients only experience chest tightness. It can be divided into typical angina pectoris and atypical angina pectoris:

1. Typical symptoms of angina pectoris

Sudden onset of squeezing, stuffy or suffocating pain behind the upper or middle part of the sternum, which may also affect most of the precordial area, radiate to the left shoulder, the anterior and inner side of the left upper limb, and reach the ring finger and little finger, occasionally accompanied by a sense of impending death, often forcing the patient to stop activity immediately, and in severe cases, sweating. The pain lasts for 1 to 5 minutes, rarely more than 15 minutes; the pain disappears within 1 to 2 minutes (rarely more than 5 minutes) after resting or taking nitroglycerin. It often occurs when you are tired, emotionally excited (angry, anxious, over-excited), cold, full, or smoking. It can also be triggered by anemia, tachycardia, or shock.

2. Atypical angina symptoms

The pain may be located in the lower sternum, left precordial area or upper abdomen, radiating to the neck, mandible, left scapula or right chest. The pain may disappear quickly or only cause discomfort or stuffiness in the left chest.
