The trend of lowering the age of cardiovascular morbidity is becoming more and more obvious, and hypertension, diabetes and coronary heart disease are no longer just old age diseases. According to the statistics of the Department of Cardiology of Xinhua Hospital of Shanghai Second Medical University, the youngest patient with coronary artery stenosis confirmed by coronary angiography in our hospital was only 18 years old, while the youngest patient who had to undergo coronary stenting angioplasty due to severe coronary lesions was 32 years old. Cardiovascular disease is not innate, years of clinical epidemiological studies point out that it is closely related to bad habits, and bad habits as early as during adolescence that have been developed, and through years or even decades of slow accumulation of the development process, this progressive pathophysiological process is known as “cardiovascular linkage “During this time we have many opportunities to stop the progression of its pathology, active prevention and treatment of hypertension, hyperlipidemia, obesity, smoking cessation, appropriate physical exercise force, is the basic link of our intervention. In the United States, from 1950 to 1995, the mortality rate of coronary heart disease decreased by 50% and stroke by 70%, which are the effects of intervention strategies to adopt prevention-oriented and active changes in poor lifestyle habits. Hypertension is one of the most important causes of heart disease, China’s current not only hypertension awareness rate is low, the treatment rate is low, blood pressure control is even lower, the incidence of adolescents is increasing year by year, overweight, high salt diet, long-term stress, these lifestyles are the risk factors that lead to hypertension, such as body mass index BMI for every increase of 1, the incidence of hypertension risk factors increased by 9% in 5 years, our physiological needs Salt intake as little as 0.5g per day, but in fact we greatly exceed the limit, and adolescents long-term mental stress, anxiety, depression can make the cerebral cortex central dysfunction, increased sympathetic excitability, systemic small artery constriction, resulting in hypertension. Smoking can raise cholesterol and triglyceride levels, lower HDL levels, and increase the risk of atherosclerosis. With the improvement of living standards, fast food such as McDonald’s and Kentucky Fried Chicken, cola drinks with high sugar content, chocolate ice cream and other sweet foods are becoming the mainstream diet of many teenagers. The most important feature of these foods is that they are high in sugar, calories, cholesterol and fiber, which can lead to hyperlipidemia, obesity, hypertension and even diabetes and premature cardiovascular diseases. A reasonable diet for adolescents should be balanced and rich, reflecting high protein, high vitamin, high fiber, low fat and low calories, specifically more cereals, beans and vegetables, fruits, milk, appropriate white meat with less calories (chicken, duck, fish) and less red meat with high calories (pig, sheep, cow), where vegetables, fruits, beans, oats, corn, seaweed contain soluble fiber, which can increase cholesterol excretion in the intestine, while fresh fruits and vegetables are rich in antioxidant vitamin C and vitamin E, which prevent damage to the heart and vascular endothelial cells.
