The main clinical manifestations of angina pectoris, 5 major characteristics to know

Typical angina pectoris has five common typical characteristics when it occurs, such as sudden chest pain, which will also radiate to the left back and left shoulder. The attack is usually short-lived and will only last a few minutes. Symptoms of angina pectoris require early treatment.

1. There are five characteristics of typical angina attacks

1. Sudden chest pain, located behind the upper and middle part of the sternum, may radiate to the left shoulder, left back, and the anterior and medial side of the left upper limb to the ring finger and little finger.

2. The nature of the pain is dull pain, which is constrictive, suffocating, or accompanied by severe compression. In severe cases, patients will sweat and look pale, which often forces them to stop activities.

3. There are often certain inducing factors, such as mental stress, emotional excitement, cold, full meals, excessive fatigue, etc.

4. It lasts for a short time, usually 1-5 minutes, and rarely exceeds 10-15 minutes.

5. The symptoms can be relieved quickly after resting or taking nitroglycerin tablets.

2. Symptoms of angina pectoris.

1. Exertional angina pectoris is characterized by short-term chest pain attacks induced by exercise or other situations that increase myocardial oxygen demand. The pain often disappears quickly after rest or sublingual nitroglycerin.

2. Spontaneous: Spontaneous angina pectoris is characterized by chest pain that has no significant relationship with the increase in myocardial oxygen demand. This pain generally lasts longer, is more severe, and is not easily relieved by nitroglycerin, and no enzyme changes are observed. Electrocardiograms often show some temporary ST segment depression or T wave changes. Spontaneous angina pectoris can occur alone or in combination with exertional angina pectoris.

Patients with spontaneous angina pectoris may have different clinical manifestations due to the frequency, duration and severity of pain. Sometimes, patients may have a long-lasting chest pain attack, similar to myocardial infarction, but without characteristic changes in electrocardiogram and enzymes.

Through the detailed introduction above, I believe everyone must have a deeper understanding now. In daily life, if you find middle-aged or elderly people showing the above symptoms, you must be very careful and vigilant, and actively go to the hospital for detailed examination and treatment. To avoid greater physical harm and pain.
