Angina pectoris is a condition of chest pain caused by insufficient blood supply to the coronary arteries. Symptoms of angina pectoris include:

2. Duration of pain: generally a few minutes, rarely more than half an hour.
3. Predisposing factors: exertion, emotional agitation, cold, full meals, smoking, etc.
4. Accompanying symptoms: sweating, nausea, vomiting, shortness of breath, etc.
2. Causes of angina
The main cause of angina is a lack of blood supply to the coronary arteries, resulting in a lack of oxygen to the heart muscle. Coronary atherosclerosis is the most common cause of insufficient blood supply to the coronary arteries. In addition, coronary artery spasm, thrombosis, etc., can also cause angina.
3. First aid for angina
1. Stop activities immediately: As soon as angina occurs, you should immediately stop the ongoing activities and sit or lie down to avoid nervousness and anxiety.

3. Call 120: If angina lasts for a long time, more than 20 minutes, or is accompanied by symptoms such as sweating, nausea, vomiting, etc., you should immediately call 120 emergency number and seek professional medical attention.
4. Stay calm: When angina attacks, keep your mind calm and avoid tension and anxiety to avoid aggravating the condition.

6. Seek medical attention in time: When angina occurs frequently, or the condition worsens, you should seek medical attention as soon as possible for further examination and treatment.
In short, patients with coronary heart disease should master the first aid method of angina, so that they can take timely measures to alleviate the condition and reduce the risk in the event of sudden angina.
