With the growth of the economy and the improvement of living standards, the population with poor lifestyles such as high-calorie diets, chronic mental stress, smoking, excessive alcohol consumption, and insufficient physical activity is rapidly expanding. The rapid economic growth brings us not only prosperity, but also a by-product — hypertension. In 2005, cardiovascular diseases caused by hypertension became the first cause of death in China, and the direct and indirect costs of hypertension comorbidities and complications were about 300 billion RMB in 2005. Although the government and various medical professional organizations have done a lot of work, we still face a huge challenge. According to the survey figures in 2002, among 160 million hypertensive patients in China, 150 million of them do not know what hypertension is or their blood pressure is not effectively controlled. Therefore, the awareness rate and control rate of hypertension in China should be improved. First of all, we will introduce the diagnostic criteria of hypertension: 1. Systolic blood pressure (high pressure ) ≥ 140 mmHg and or diastolic blood pressure (low pressure) ≥ 90 mmHg without the use of anti-hypertensive drugs; 2. Patients with a previous history of hypertension, currently using anti-hypertensive drugs, although the blood pressure is lower than 140/90 mmHg, should also be diagnosed as hypertension. Hypertension is very insidious, you may not feel any discomfort, so it is called the “silent killer”. Many sudden unexpected deaths of patients with hypertension and its complications could have been avoided with basic knowledge of prevention and treatment, but they did not die from the disease, but from ignorance. Hypertension is a chronic lifelong disease, and long-term hypertension can directly cause damage to many important organs such as the heart, brain, kidney, and fundus, and hypertension and hypertensive risk factors such as obesity, smoking, hyperlipidemia and diabetes and other concomitant diseases work together to cause myocardial infarction, stroke and a series of life-threatening cardiovascular diseases, also known as cardiovascular events. Hypertension causes cerebral ischemia and cerebral hemorrhage, and one Chinese person has a stroke every 12 seconds, and one Chinese person dies from a stroke every 21 seconds. The annual cost of stroke treatment is about 26.3 billion RMB, and the indirect cost is estimated to be nearly 200 billion RMB. Hypertension can lead to decreased kidney function; it can also lead to vascular and retinal lesions in the fundus of the eye, and in severe cases, blindness. Therefore, you should go to the hospital promptly after you find your blood pressure is higher than normal to prevent or delay the complications of hypertension.
