Coronary Heart Disease, CHD refers to myocardial hemorrhage caused by coronary coronary porridge hardening or other causes, which is one of the leading causes of cardiovascular disease deaths worldwide. As lifestyles change and population ageing, the incidence of coronary heart disease increases every year, becoming one of the diseases that seriously threaten human health. The definition, causes, symptoms, diagnosis, treatment and prevention of coronary heart disease will be described in detail in this paper to help the public better understand the disease.
I. Definition of coronary heart disease
Coronary heart disease is defined as a type of disease that is coronary artery coronary coronary sclerosis, haemobolism or other factors that causes narrowness or obstruction, which causes myocardial hemorrhage, anaerobics, and leads to impaired heart function. Depending on the condition, coronary heart disease can be divided into different types of stable heart pain, unstable heart pain, heart infarction, etc.
II. Causes of illness
The occurrence of coronary heart disease is closely related to a number of factors, including:
1. Sclerosis of the aneurystic porridge: this is the most important cause of coronary heart disease, which leads to a narrow vascular cavity by pointing to lipid deposition within the arterial wall, inflammation response and increased fibrous tissue.
High blood pressure: Long-term hypertension accelerates the sclerosis of the artery and increases the heart burden.
3. High blood resins: elevated levels of cholesterol and triester in blood, which can easily form an avial porridge sample and hardened specks.
Diabetes: Poor blood sugar control by diabetic patients can damage the inside of the veins and contribute to the hardening of the artery.
5. Smoking: Tobacco use leads to vascular constriction, increased blood stickyness and increased risk of cardiovascular disease.
Obesity: Overweight and obesity are closely related to a wide range of coronary heart disease risk factors, such as hypertension, hypertension and diabetes.
Lack of exercise: Lack of physical exercise leads to metabolic disorders and increases the risk of coronary heart disease.
Genetic factors: Family history is also an important risk factor for coronary heart disease.
9. Psychological factors: Long-term stress, anxiety and depression can also increase the risk of coronary heart disease.
III. Symptoms
Symptoms of coronary heart disease vary from one individual to another, and common symptoms include:
1. Heart pain: Patients often feel the feeling of chest oppression, pain or discomfort, usually increased after physical exercise, emotional excitement or eating and reduced after rest.
2. Respiratory difficulties: The patient may feel anxious to breathe when he or she is active or emotional.
Heart palpitation: The patient may feel his or her heart beating accelerated or irregular.
4. Powerlessness: due to a lack of blood supply in the heart, the patient may feel extremely tired.
5. Disgusting or sweating: When the heart of a person suffers from an anorexia, the patient may be associated with symptoms of nausea, vomiting or sweating.
In serious cases, coronary heart disease can lead to myocardial infarction in the form of severe chest pains, respiratory difficulties, loss of consciousness, etc., requiring immediate medical attention.
Diagnosis
The diagnosis of coronary heart disease usually includes the following steps:
1. Medical history inquiries: Doctors are asked in detail about patients ‘ symptoms, family history and life habits.
Medical examination: assessment of heart function through consultations, consultations, etc.
3. Ethiocardial graph (ECG): it can help detect the electrical activity of the heart and identify signs of heart pain or myocardial infarction.
4. Cardiac ultrasound: Assessment of the blood supply of the heart muscle by ultrasound examination of the heart structure and function.
5. Coronary artery imaging: direct observation of the narrowness or blockage of the coronary artery by injection of a photographing agent and X-ray examination.
Exercise load test: Assessment of the blood supply capacity of the heart by monitoring changes in the EKG of the patient during exercise.
Treatment
The treatment of coronary heart disease includes medication, intervention and surgical treatment, with specific programmes depending on the patient ‘ s condition.
1. Drug treatment:
Anti-blood tablets: e.g. aspirin, to prevent the formation of blood clots.
Beta-adrenergic restraining agent: reduced heart burden and reduced heart pain.
ACE inhibitor: improved heart function and reduced blood pressure.
Tatin: Decreasing blood resin and slowing down the sclerosis of the artery.
2. Interventions:
Treatment with coronary artery (PCI): Placing a stand within a narrow coronary artery through catheter technology to restore blood flow.
3. Surgery:
Coronary artery by-pass (CABG): A new blood circulation route is created by operation, bypassing a narrow or blocked coronary artery.
Prevention
The key to the prevention of coronary heart disease is a healthy lifestyle, which includes:
1. Healthy diet: balanced diet, increased intake of fruit, vegetables, whole grain, reduced intake of saturated and trans-fat.
2. Regular exercise: aerobics with a medium strength of at least 150 minutes per week, such as walking, swimming, etc.
3. Weight control: maintain healthy weight and avoid obesity.
4. Prohibition of smoking: cessation of smoking, restriction of alcohol intake and reduction of the risk of cardiovascular disease.
Periodic medical examinations: periodic monitoring of blood pressure, blood resin and blood sugar to detect and manage potential risk factors at an early stage.
Mental health: maintain a good psychological state, learn to depress and relax.
Conclusions
Coronary heart disease is a serious cardiovascular disease and understanding of its causes, symptoms, diagnosis and treatment is essential for prevention and management. Many risk factors for coronary heart disease can be controlled through healthy lifestyles and periodic health examinations. It is hoped that this paper will help readers to better understand coronary heart disease, raise awareness of self-protection and maintain heart health. If the symptoms are relevant, prompt medical treatment is recommended and professional medical advice is sought.
