Sometimes, a single word can save a life. Health education plays a very important role in the prevention and treatment of cardiovascular diseases. Western developed countries attach great importance to health education, and many health education scholars have emerged in China, such as Hong Zhaoguang and Hu Dayi. In the prevention and treatment of cardiovascular diseases, medical workers at home and abroad have summarized many good methods that are easy to remember and easy to learn. Remembering these numbers and implementing them is beneficial to the prevention and treatment of cardiovascular disease. The “four cornerstones” of a healthy lifestyle: reasonable diet, moderate exercise, smoking cessation and alcohol restriction, and psychological balance. Implement the two “ABCDE” measures for secondary prevention of coronary heart disease: aspirin, angiotensin-converting enzyme inhibitor (ACEI), beta-blocker, blood pressure control, and blood pressure control. Bloodpressurecontrol, Cholesterollowering, Cigarettequitting, Diabetescontrol, Diet, Exercise, and Education. The three “no’s” to prevent hypertension are Prevention of hypertension three “no” and three “half”: for the prevention and health care of hypertension, in addition to adhere to the medication, steady lowering of blood pressure, should remember the American health experts proposed three “no “No”, that is, no tension, no anxiety, no hypertension. The “three half minutes and three half hours” are to continue to lie down for half a minute after waking up, to sit in bed for half a minute after getting up, to wait for another half minute with legs hanging down on the edge of the bed; to exercise for half an hour in the morning, to sleep for half an hour at noon, and to walk for half an hour after dinner. The daily prevention of cardiovascular disease should build “five lines of defense”: prevention of morbidity, prevention of cardiovascular events, prevention of consequences, prevention of recurrence, and prevention of heart failure. Control the “eight highs” through the “six pathways”: the “six pathways” are weight loss, sugar reduction, blood pressure reduction, lipid regulation, viscosity reduction and reduction of insulin resistance. The “eight highs” are high body weight, high blood pressure, high blood sugar, high blood fat, high blood viscosity, high uric acidemia, high incidence of fatty liver and high insulinemia. Nine kinds of exercises can be chosen: brisk walking, jogging, swimming, cycling, stair climbing, hiking, dancing, rice-singing, and tai chi. On top of conventional drug or non-drug treatment, health care providers should provide necessary health education to patients, either in the hospital or in the community. Hospitals should also include health education in outpatient and inpatient care. The effectiveness of cardiovascular health education can be measured by seven indicators, namely the number of cardiovascular events (hypertensive emergencies, angina attacks, acute myocardial infarction, malignant arrhythmias, acute heart failure, etc.), the number of follow-up outpatient visits (meaning symptomatic visits, not just medication pickup), readmission rates, cure rates, mortality rates, average hospitalization days and medical costs. Health education has an effective reinforcing, complementary and enhancing effect on pharmacological or non-pharmacological treatment of cardiovascular disease patients. On the one hand, it facilitates good communication and establishes a good doctor-patient relationship; on the other hand, it increases patients’ compliance with pharmacological or non-pharmacological treatment.
