Patients with hypertension are often asked to do ultrasound, blood and urine tests, and even CT or other special tests, which often makes many patients do not understand that high blood pressure, as long as the blood pressure is measured, medication and treatment, do not need to do a number of tests. The key to this understanding is the lack of comprehensive understanding of hypertension. Hypertension is divided into primary and secondary hypertension. Primary hypertension generally requires lifelong use of antihypertensive drugs, while secondary hypertension is often caused by certain diseases and requires active treatment of the primary disease. When hypertension is detected, the doctor must conduct a thorough evaluation of the patient to determine which type of hypertension is present. Therefore, hypertensive patients need to do the following tests: 1, blood pressure measurement: including outpatient occasional blood pressure measurement, ambulatory blood pressure monitoring, a comprehensive assessment of the patient’s blood pressure, for elderly patients with hypertension, it is best to bring their own blood pressure monitor at home to monitor blood pressure every day. 2, routine urine examination: to see whether the patient’s kidney function is impaired. If there is protein, red blood cells and other conditions indicate kidney damage, it is necessary to understand the causal relationship between hypertension and kidney damage. 3, blood biochemical examination: blood sugar, blood lipids, urea nitrogen, creatinine, etc. can be checked. The assessment of these indicators is necessary because these factors often constitute a “metabolic syndrome” together with hypertension.4. CT or MRI: It is important to detect renal, adrenal and intracranial lesions.5. ECG: To assess left ventricular strain and determine myocardial ischemia.6. Echocardiography. It is more sensitive to left ventricular hypertrophy than electrocardiography, and can also measure ventricular function and ejection fraction, which is currently the most common way to assess cardiac function.7.Fundus examination: It is one of the important indicators to determine the prognosis of hypertension.8.Arterial function measurement: To understand the degree of arteriosclerosis and the possibility of stenosis or blockage. Therefore, when high blood pressure is found, it is important to find a specialist to check it out first and treat it symptomatically so as not to delay the condition.
