summary

What does medical CHD mean? Coronary heart disease (CHD) is the general term of heart disease (coronary atherosclerotic heart disease) and coronary artery functional changes (spasm) caused by myocardial ischemia and hypoxia caused by coronary artery occlusion, also known as "ischemic heart disease". Clinically, it can be divided into primary cardiac arrest, angina pectoris, myocardial infarction, heart failure and arrhythmia. CHD is a psychosomatic disease which seriously threatens people's health and causes a lot of deaths. The incidence rate increased gradually half a century ago. Coronary heart disease is the most common heart disease in the elderly. The disease is described below.

What does medical CHD mean?

First of all, the risk factors of coronary heart disease refer to the risk factors that affect the occurrence and development of coronary heart disease. According to the order of their severity, they are: ① the increase of blood lipids, especially the increase of blood cholesterol, can promote the occurrence and development of coronary heart disease. Hypertension, the higher blood pressure, the higher incidence rate. The prevalence of coronary heart disease in the elderly with systolic blood pressure higher than 180 mmHg is 6 times higher than that in the elderly with systolic blood pressure higher than 120 mmHg. ③ Although smoking and CO (carbon monoxide) in the smoke can increase the coronary artery blood flow when the blood carboxyhemoglobin reaches 90%, it is prone to myocardial ischemia because the coronary atherosclerosis can not compensate.

Secondly, coronary heart disease is divided into five types, namely recessive coronary heart disease, angina pectoris, myocardial infarction, myocardial sclerosis and arrhythmia. In the pathological anatomy, the coronary artery of patients with recessive coronary heart disease has changed, but clinically, the elderly have no myocardial ischemia, and generally have no cardiac symptoms. Angina pectoris, the most common disease, is due to atherosclerosis and stenosis of the main coronary artery, and the increase of the degree of high stenosis of the coronary artery. Men appear earlier than women, 50 years old for men and 60 years old for women. Angina pectoris attack is related to the degree of collateral circulation formed by coronary circulation. Acute myocardial infarction, due to thrombosis in the hardened coronary artery, causes local myocardial ischemia, and then develops into myocardial necrosis, and even leads to myocardial rupture. Myocardial sclerosis is mainly associated with coronary atherosclerosis, long-term myocardial blood supply disorders, resulting in myocardial dystrophy, atrophy, connective tissue hyperplasia, and finally myocardial sclerosis. Arrhythmia, coronary heart disease, especially acute myocardial infarction, at the beginning of 80% of patients prone to arrhythmia, ventricular premature beats, tachycardia, ventricular fibrillation, sinus bradycardia, atrioventricular junction rhythm, atrioventricular block, etc. Arrhythmia can be the cause of acute myocardial infarction.

Finally: differential diagnosis; With the increase of age, the physiological function of the elderly is declining, the constitution is weak and the chronic diseases are beset, and the number of coronary heart disease is increasing. In clinical practice, there are many complications, but the clinical characteristics of coronary heart disease are not obvious, so it is difficult for doctors in the process of diagnosis and treatment. In clinic, arrhythmia, angina pectoris, myocardial infarction, heart failure and other symptoms are common. Due to the acute onset of the disease, it is easy to die suddenly when the disease is serious. Compared with the middle-aged, the clinical symptoms of coronary heart disease are not obvious.

matters needing attention

After the discovery of coronary heart disease, we should pay attention to the prevention of sudden death due to cardiac arrest. Pay attention to avoid emotional excitement, avoid excessive physical activity, but should be mild and appropriate physical exercise, in order to prevent atherosclerosis and obesity. Arrange a reasonable and balanced diet and eat more fruits and vegetables. Excessive stress should be avoided in work and life. Avoid psychological conflict. We should get enough sleep and advocate no smoking and drinking. Drugs can be vasodilator drugs, active treatment of arrhythmia. Acute myocardial infarction should be monitored in hospital until it is out of danger.
