Many middle-aged and elderly friends suffering from hypertension, through the doctor’s regular diagnosis and treatment, after adhering to the medication for a period of time, the original very high blood pressure, was controlled normal, that is to say, has reached the standard, the standard blood pressure is also in the 130/80 below. At this point, it is often thought without thinking that it is time to stop the medication. At first glance, there is nothing wrong with this idea, since the blood pressure is normal, there is no need to continue to take antihypertensive drugs. In reality, is this really the case? 1, the goal of hypertension control: to achieve the standard Suffering from hypertension, diagnosed with hypertension, then, under the diagnosis of the doctor, through the doctor to determine the control program, adhere to the medication, and strive to make it achieve the standard, this is both the basic requirements of the doctor, but also for each hypertensive patient’s basic requirements. The numerical expression of this basic requirement is: the blood pressure standard. Currently, the accepted level of attainment is: systolic blood pressure below 130mmHg, diastolic blood pressure below 80mmHg. 2, blood pressure standard is not the purpose, the purpose of blood pressure control is to prevent and control complications related to hypertension As hypertensive patients, often think that the purpose of taking drugs to lower blood pressure is to make blood pressure standard, in fact, it is not. The real purpose of taking medication to lower blood pressure and make it reach the standard is to prevent and control complications related to hypertension, which are mainly cardiovascular and cerebrovascular complications, but also include fundus complications, renal vascular complications and lower limb arterial vascular and even pulmonary vascular complications. By controlling blood pressure, we strive to lower blood pressure to reach the standard state, thus reducing the occurrence of cardiovascular and cerebrovascular events, as well as slowing down the speed and degree of arteriosclerosis of the fundus, and preventing the damage to kidney function caused by the sclerosis of the kidney vessels. This is the purpose of blood pressure control. Many friends, especially those with high blood pressure, do not want to suffer from myocardial infarction, cerebral thrombosis, kidney function damage, etc. when they are in their prime or around 60 or 70 years old. This is the consensus of the people. 3, think that blood pressure has reached the standard to stop the drug, the real idea is to worry about the side effects of drugs This worry seems reasonable, but also in fact some superfluous. Because the current antihypertensive drugs, can be said to be very safe. They are confirmed by large-scale experiments.
