Hypertension as the most common cardiovascular disease, its harm is huge. First of all, cardiovascular diseases such as myocardial infarction and coronary heart disease, the main cause is hypertension, according to statistics, 40-50% of myocardial infarction is related to hypertension; and cerebral infarction, the main cause of brain hemorrhage is also hypertension, according to statistics, 50-60% of strokes are related to hypertension; long-term hypertension can also lead to renal Long-term hypertension can also lead to renal arteriosclerosis, thus causing renal insufficiency, uremia, etc. Hypertension has been on the rise in the developed countries of the world in the past. Before the 1980s, this disease was less common in China. However, at the World Health Assembly in 1976, it was predicted that cardiovascular disease was emerging as a public health problem in developing countries, both in absolute and relative terms, and that it would increase with the economic development of the country as a whole. This prediction now appears to be accurate. Prior to the 1990s, most hospital outpatient and inpatient visits in China were for digestive and infectious diseases, but since the 1990s there has been a significant decrease in these patients and a significant increase in cardiovascular and cerebrovascular diseases. The number of deaths due to cerebrovascular diseases and renal atherosclerosis is also expanding. In 2002, the prevalence of hypertension among adults over 18 years old was 18.8%. The World Health Organization in 1992 had announced an alarming figure: in the world, cardiovascular disease took 12 million lives each year, close to 1/4 of the total number of deaths in the world, so it has become the number one enemy of mankind, known as the first human killer. China’s hypertension incidence of about 160 million people, and the annual rate of 3.5 million people increasing. And many people who suffer from hypertension and even cause death die prematurely, these people are in the middle age of vitality and creativity, they die in the spring of life, is the vigorous life suddenly stopped. Some of our important leaders have also died from this disease. From the people around us we also hear about such things happening. Shandong had done a survey in 2007 on people over 40 years old in its territory and found that more than 30% of them suffered from hypertension, which is a rather alarming set of findings. Dr. Hiro Nakajima, director general of the World Health Organization, said, “In today’s world, cardiovascular disease kills more people than any other single disease. And it cripples millions of people.” It is no exaggeration to call hypertension the “number one human killer.
