Cardiovascular disease is a common chronic non-communicable disease. Common cardiovascular diseases include coronary heart disease, arrhythmia and heart failure. 1. Coronary heart disease: Coronary heart disease refers to heart disease caused by atherosclerosis of the coronary arteries, resulting in narrowing or occlusion of the lumen, leading to myocardial ischemia, hypoxia or necrosis. Including a variety of different clinical manifestations, common clinical manifestations include chest tightness, chest pain, palpitations (rapid heartbeat, often accompanied by panic), cough and so on. Patients can get better therapeutic effect through medication, coronary intervention or bypass surgery. 2. Arrhythmia: Arrhythmia refers to the abnormality of the frequency, rhythm, origin, conduction speed or order of excitement of the heart impulse, which can be seen in physiological conditions, but more often in pathological conditions. It is often characterized by chest pain, dizziness, blackouts and palpitations. It can be clarified by 24-hour dynamic electrocardiogram and treated by medication or radiofrequency ablation. 3. Heart failure: It is the end stage of cardiovascular disease. It often manifests itself in different degrees of dyspnea, cough, sputum and so on. Clinical treatment programs are often adopted to slow down the progression of the disease. 4. Other: in addition to the above common diseases also include hypertension, cardiomyopathy such as dilated cardiomyopathy, hypertrophic cardiomyopathy, congenital heart disease, heart valve disease such as mitral stenosis, closure of insufficiency, etc., in addition to pericarditis and infective endocarditis, as well as the aorta and peripheral vascular disease. Cardiovascular disease is a serious threat to human health, characterized by high prevalence, high disability rate and high mortality rate, this patient group should maintain a healthy lifestyle, smooth emotions, and follow the doctor’s instructions to standardize the use of drugs.
