What are the signs of angina? How do we treat it?

**Drugs for angina include antiplatelet drugs, including commonly used aspirin and clopidogrel, which may reduce the risk of heart attack, stroke, or cardiovascular death. If a patient is stented, aspirin, clopidogrel, or ticagrelor should be changed to aspirin after one year of combination. There are also drugs that can reduce the number of attacks and are especially suitable for patients with hypertension and arrhythmias, but should not be used in patients with angina with bronchial asthma.

Finally, there are calcium antagonist drugs, which are relatively small but widely used.

The front feet in the new body generally have a feeling of compression, squeezing, chest tightness and poor breathing, generally depending on the situation, and nitroglycerin is commonly used.

Angina pectoris is a clinical syndrome caused by coronary insufficiency, acute and temporary ischemia and hypoxia of myocardium. It is characterized by paroxysmal anterior chest squeezing pain, mainly located in the posterior part of the sternum, can radiate to the precordial area and the left upper limb, often occurs during labor or emotional agitation, lasts for a few minutes, the disease is more common in men, most patients in the age of 40 years old when the attack immediately rests, the general patient can be eliminated after stopping activities. 2. Drug**, immediately sublingual nitroglycerin.

3. Surgery**. 4. Carefully arrange appropriate exercise.

Angina pectoris is a clinical syndrome with episodic chest pain or chest discomfort caused by coronary insufficiency, acute temporary ischemia and hypoxia of myocardium. **: When angina occurs pectoris, the patient and the patient's family and friends must know how to deal with it correctly.

1. Rest immediately. When angina infiltrates the congru, the patient should immediately stop working or moving his hands, stop and rest, and the patient's symptoms can be relieved after a period of rest. 2. Appropriate use of drugs**.

If rest doesn't work, or if the attack of angina is severe, nitrates may be used to help relieve symptoms. (1) Nitroglycerin. It is generally recommended to put nitroglycerin under the tongue to absorb it, as the saliva will quickly dissolve the nitroglycerin and be absorbed by the body.

However, after taking nitroglycerin, patients may experience ***, such as flushing, heart palpitations, etc. (Zheng Chong 2) isosorbide nitrate. It is generally recommended to put isosorbide nitrate under the tongue, but it can also be sprayed into the mouth for absorption.

In addition, isoamyl nitrite also has the same effect as nitrate preparations, and the action time is faster and shorter, and the effect of lowering blood pressure is also more obvious, so patients should use it with caution. If the angina pectoris is severe, the patient should go to the hospital in time and choose a more appropriate method, such as surgery, under the guidance of the doctor.

Angina pectoris can be triggered by exertion, agitation, overeating, cold, infection, hyperthyroidism, tachycardia, etc.

The symptoms of angina pectoris are mainly chest pain, which is characterized by:

1. The site mainly affects the precordial area after the sternal body, the size of the palm, and even across the chest, often discharging to the left shoulder, the inner side of the left arm, the ring finger and little finger, or the neck, pharynx, and mandible;

2. The nature of pain is often dull and dull, oppressive, tight, burning, knife-cut, and drilling. When angina attacks, people are often forced to stop ongoing activities until symptoms resolve;

3. The predisposing factors often occur during physical activity or emotional agitation, and sometimes full meals, cold, smoking, tachycardia, and shock can also be induced;

4. The duration of time is often gradually aggravated after appearing, and lasts for 3-5 minutes after reaching a certain level, rarely exceeding half an hour;

5. The relief method is generally to stop the original activity or take nitrate and other drugs under the tongue, which can be relieved within a few minutes.

Angina pectoris can cause myocardial segmental movement abnormalities, electrical instability, and structural dysfunction of the heart, which can lead to heart failure, arrhythmia, and sudden death in severe cases. Long-term angina pectoris can cause myocardial hibernation, stagnation, fibrosis, symptoms of chronic congestive heart failure, and sudden death in the course of the disease.

It is characterized by sudden-onset crushing, bulging, or asphyxiating pain located behind the upper or middle sternal body, and may also affect most of the precordial area, radiating to the left shoulder, anteromedial aspect of the left upper extremity, and reaching the ring finger and little finger. The pain lasts 1 to 5 minutes and rarely exceeds 15 minutes; With rest or nitroglycerin, the pain disappears within 1 2 minutes (rarely more than 5 minutes). It usually occurs during exertion, agitation (anger, anxiety, overexcitement), cold, full food, smoking, and can also be induced by anemia, tachycardia, or shock.

Chest pain is the most common when angina is attacked, and some chest pain radiates to the shoulder, which is manifested as heaviness, sleepiness, and soreness in the left shoulder, and there are also some angina attacks, which are manifested as toothache.

Angina pectoris is caused by a transient lack of oxygen to the heart, so it lasts for a very short time and the pain is usually behind the sternum, and the pain is crushing.

Suddenly, there will be a sharp pain in the heart, and after a while it will regain its calmness and be more easily frightened.

When angina occurs in nature, the nature of the pain is mainly squeezing, with a feeling of pressure, tightness, burning, and even a sense of impending death. It varies from person to person, and the nature of pain varies slightly from person to person; The pain is felt differently depending on the pain tolerance level, which means that the patient's pain threshold also affects the nature and degree of pain.
