For each patient in the hypertension department, three issues should be clarified before receiving treatment: 1. find out what causes or diseases cause hypertension; 2. understand the patient’s heart, brain and kidney condition; 3. identify cardiovascular disease risk factors other than hypertension. In this way, the patient can be given comprehensive treatment. First, find out what causes or diseases cause hypertension. The doctor understands in detail to the patient the occurrence and development process of hypertension, find out the particular disease that causes hypertension, and after symptomatic treatment, hypertension will be cured. For patients with primary hypertension, it is important to analyze what susceptibility factors may be causing the patient’s blood pressure to rise. Such as mobilization of some hypertensive patients with high salt diet to take a low-salt diet, the result of the blood pressure fell to the ideal level, and some people even do not have to take antihypertensive drugs blood pressure also returned to normal. Second, understand the patient’s heart, brain and kidney situation. If the patient has the corresponding symptoms of heart, brain and kidney damage, suggesting that the target organs may have occurred some disease, should be promptly further diagnosis and treatment, because the purpose of hypertension treatment is to protect the heart, brain and kidney from damage. To prevent the recurrence of heart, brain and kidney damage, it is necessary to lower blood pressure sufficiently and reasonably. For example, after cerebral thrombosis, even in patients with normal high blood pressure, taking angiotensin-converting enzyme inhibitor perindopril and diuretics can prevent the formation of cerebral thrombosis again. Third, cardiovascular disease risk factors other than hypertension should be identified. If we only pay attention to controlling blood pressure and neglect to eliminate other factors, the treatment will be incomplete and incomplete, and the expected efficacy will not be achieved. Patients with hypertension should also pay attention to the above three aspects at all times in the later follow-up treatment.
