Hypertension is a common disease that seriously endangers human health and is the most important risk factor for coronary heart disease, stroke and renal failure, and cardiovascular disease has become the leading cause of human death. In China, there are “three high”, “three low” and “three no” phenomenon of hypertension. The “three highs” mainly refer to: high prevalence, high mortality rate and high disability rate. According to the results of the 2002 survey on the nutrition and health status of Chinese residents, the prevalence of hypertension among Chinese adults has reached 18.8%, that is, there are about 160 million hypertensive patients nationwide, and one out of every five adults suffers from hypertension! Moreover, with the aging of China’s population, the prevalence of hypertension is increasing at a rate of more than 3 million people per year, and is showing a trend of youth. The danger of hypertension is beyond doubt, but unfortunately, there is a low awareness rate of hypertension, low medication rate, low control rate of the “three low” phenomenon in China’s urban and rural areas. According to the survey, 53% of people had their blood pressure measured, but only 4% of people who know their blood pressure level only 17.1% of hypertensive patients for treatment; only 4.1% adhere to the medication and blood pressure control within the normal range. Studies have confirmed that early prevention and treatment of hypertension and rational use of medication can reduce serious complications of hypertension by 50%, significantly reduce disability and mortality rates, and improve quality of life. However, hypertension patients take medication and there is a common phenomenon of “three no’s”: irregular medication, not uncomfortable not to take medication, do not love the medication, so that hypertension in the subtle devouring of human health, and eventually lead to heart, brain, kidney and other important organ damage, so hypertension is also known as the “silent killer This is why hypertension is also known as the “silent killer”.
