Coronary heart disease is the abbreviation of coronary atherosclerotic heart disease. It refers to a kind of heart disease, also known as ischemic heart disease, which is caused by severe atherosclerosis or spasm of the coronary artery, which supplies nutrients to the heart, so that the coronary artery is narrowed or blocked, and thrombosis causes lumen occlusion, which leads to myocardial ischemia and hypoxia. Coronary heart disease is the most common type of organ disease caused by atherosclerosis, and it is also a common disease that harms the health of middle-aged and elderly people. The occurrence of this disease is closely related to the degree and number of coronary artery stenosis, but a small number of young patients with coronary atherosclerosis can get sick even though it is not serious. There are also some elderly people with severe coronary atherosclerotic stenosis, but not all of them have clinical manifestations of coronary heart disease such as chest pain and palpitation. Therefore, the pathogenesis of coronary heart disease is very complicated. Generally speaking, it is organic, and coronary artery spasm also occurs in atherosclerotic coronary arteries.

If the following situations occur, you should seek medical advice in time to find coronary heart disease as soon as possible.

(1) Suffering from chest tightness or constrictive pain in the posterior sternum or precordial region during fatigue or mental stress, radiating to the left shoulder and left upper arm for 3-5 minutes, and then relieving by itself after rest.

(2) Chest tightness, palpitation and shortness of breath occur during physical activity, and they relieve themselves at rest.

(3) Headache, toothache and leg pain related to exercise.

(4) Those who have chest pain and palpitations when they are full of food, cold or watching thrilling movies.

(5) Those who feel chest tightness and hold their breath when sleeping with a low pillow at night and need a high pillow to feel comfortable; Those who suddenly have chest pain, palpitation and dyspnea while sleeping or lying flat during the day and need to sit up or stand up immediately to relieve them.

(6) Palpitation, chest tightness, shortness of breath or chest pain during sexual life or forced defecation.

(7) People who feel flustered and chest tightness when hearing noise.

(8) Repeated irregular pulse and unexplained tachycardia or bradycardia.

In order to find coronary heart disease as soon as possible, people over 40 years old should have regular physical examinations; If the test results are abnormal or there are other risk factors for coronary heart disease, you should have one or more blood cholesterol tests every five years. In addition, blood pressure and blood sugar are checked once a year.

If you belong to the high-risk group of coronary heart disease, you should ask your doctor to decide whether you need to undergo ECG examination. If further examination is needed, the doctor will arrange an exercise test to measure the electrocardiogram when stepping on a stationary bicycle or a treadmill. Coronary angiography is the most sure method to diagnose coronary heart disease.
