What causes sudden angina pectoris

Angina pectoris refers to symptoms of shortness of breath and hypoxia caused by insufficient blood supply to the myocardium. This disease mainly occurs in patients with coronary heart disease, but it can also occur in patients with hypertension and heart disease, and patients still need treatment. Severe sudden angina pectoris can cause patients to experience dizziness and blood clots, so patients need to pay attention to the symptoms of sudden angina pectoris and receive treatment in a timely manner.

What causes angina?

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.

This buildup of plaque in the lining of the coronary arteries can cause angina in two ways:

① The fixed position of the coronary artery lumen is narrowed, which leads to a significant reduction in blood flow;

②The formed blood clot partially or completely blocks the coronary artery.

What to do if you have sudden angina

1 Angina pectoris is chest pain caused by insufficient blood supply to the coronary arteries, resulting in myocardial ischemia. If you suddenly have an attack of angina pectoris, you must stand still and don't panic. Try to talk less and breathe deeply. This can reduce the burden on your heart and keep yourself calm. This is very important.

2 Generally, patients with heart disease will carry some medicines with them when they go out, such as quick-acting heart-saving pills or compound danshen pills. If your condition is serious, you can ask passers-by for help and ask them to help you take medicine. Try to relax, then evacuate people around you, keep the air flowing, and immediately call 120 and wait for emergency treatment.

3Sudden angina may cause other complications, such as myocardial infarction or shock. If the patient is in critical condition, artificial respiration can be performed first to maintain her vital signs, stabilize her emotions, regulate her breathing and then send her to the hospital as soon as possible.
