Causes of angina pectoris, which one do you belong to?

The most common causes of angina pectoris are excessive fatigue and excitement. Both of these conditions can lead to insufficient blood supply to the coronary arteries, causing myocardial ischemia and leading to angina pectoris. Therefore, patients with angina pectoris must not overwork and maintain a calm state of mind.

1. Overwork

Fatigue is one of the causes of angina pectoris. Typical exertional angina pectoris often occurs during long-term intense mental work, overnight overtime, strenuous labor, fast walking, climbing mountains, going up stairs, cycling and other activities. This is because after exertion, the heart rate increases, which increases myocardial oxygen consumption, leading to insufficient blood supply to the coronary arteries and causing angina pectoris, which can usually be relieved after a short rest.

2. Emotional excitement

When the body is in a state of over-excitement, sadness, fear, etc., these emotions can be transmitted through the sympathetic nerves. On the one hand, it causes the heart rate to increase and blood pressure to rise, thereby causing increased palpitations and itching. On the other hand, it induces coronary artery spasm, reduces blood supply to the heart, and leads to the occurrence of angina pectoris.

3. Irregular heartbeat

Arrhythmia is one of the causes of angina pectoris. This is because arrhythmia causes coronary artery spasm, sudden blood vessel occlusion, myocardial ischemia, which increases myocardial consumption and reduces blood output, leading to reduced coronary blood flow, thus causing angina pectoris.

4. Overeating

Overeating is also one of the causes of angina pectoris, which can manifest as chest pain during meals or angina pectoris after meals. This is mainly because eating too much increases the energy consumed by the gastrointestinal tract to digest food, increases the burden on the heart, and reduces blood supply to the vascular arteries, thereby inducing angina pectoris.

5. Smoking and drinking

Smoking in large quantities can not only reduce the blood oxygen content and exercise tolerance of patients with angina pectoris, but also increase the sensitivity of the coronary arteries, making them prone to spasms when encountering stimulation, thereby inducing angina pectoris in the elderly or aggravating angina pectoris; drinking large amounts of alcohol can cause peripheral vascular dilation, lower blood pressure, and increase heart rate, leading to insufficient blood supply to the heart and insufficient oxygen supply to the myocardium, thereby inducing angina pectoris.

6. Iron deficiency anemia

The incidence of anemia in the elderly is quite high. When anemia occurs, the blood's ability to carry oxygen is reduced, which aggravates myocardial ischemia and hypoxia, leading to the occurrence of angina pectoris. Therefore, if patients with angina pectoris properly combine meat and vegetables in their daily diet, it will not only not aggravate their condition, but will be beneficial to their health.

7. Other factors

1. Cold: Hiking in cold weather makes the body unable to adapt, which leads to a sudden increase of norepinephrine in the body, increased heart rate, increased blood pressure, coronary artery spasm, and angina pectoris. 2. Defecation: Patients with difficulty urinating and constipation have to strain to defecate, which causes a sharp increase in intra-abdominal and intra-cardiac pressures, resulting in an increase in the patient's heart rate, increased myocardial contractility, and a sharp increase in cardiac load, thus causing angina pectoris. 2. Lying position: Some patients with angina pectoris often experience it when they are resting quietly. This is common in severe coronary artery stenosis and is considered a common cause of angina pectoris in the elderly.
