Screening for secondary hypertension includes: renal function, urine routine, hypertension series, renal artery ultrasound, adrenal CT, and treatment plan: blood pressure control and treatment of primary disease. 1. Screening for secondary hypertension: secondary hypertension is related to kidney, patients should be examined for renal function, urine routine, hypertension series and other related tests to clarify whether there are abnormalities in renal function and elevated levels of various hormones, for example, nephritis can show elevated creatinine levels and positive urine protein, adrenal disease can show abnormalities in renin and angiotensin. At the same time, we should carry out imaging examination of patients, renal artery ultrasound to clarify whether there is renal artery stenosis, adrenal CT whether there is adrenal gland occupation, etc.. 2. Control blood pressure: patients with secondary hypertension should actively control the blood pressure level, oral amlodipine, valsartan, metoprolol and other drugs, some patients need to be combined with drugs, the specific treatment program should follow the doctor’s instructions. 3. Treatment of primary diseases: for example, adrenal pheochromocytoma needs to be surgically removed, and renal artery stenosis can be implanted with stents, and appropriate treatment should be chosen according to the specific cause of the patient. If you have any symptoms of physical discomfort, you should go to the hospital in time, under the guidance of the physician, to identify the cause and then give targeted treatment.
