Hypertensive patients usually need to check items such as ECG, 24-hour ambulatory blood pressure monitoring, chest X-ray and hypertension triple test. 1. Electrocardiogram: You can choose to do electrocardiogram or echocardiogram to find out whether the patient has hypertensive myocardial damage, combined myocardial ischemia, arrhythmia and so on. 2. 24-hour ambulatory blood pressure monitoring: 24-hour ambulatory blood pressure monitoring can be used to understand the changes of the patient’s blood pressure in 24 hours. 3. Chest X-ray: Hypertension may lead to cardiac hypertrophy, and chest X-ray can be used to understand the patient’s aorta and heart condition. 4. Hypertension triple test: The renin-angiotensin-aldosterone system has the effect of constricting blood vessels, raising blood pressure and preserving sodium. Blood tests for renin, angiotensin and aldosterone are important for the identification of primary hypertension and secondary hypertension. Hypertensive patients are advised to go to the hospital for regular medical checkups to find out the recent changes in blood pressure levels, and to consult whether there is a need to adjust medications and whether there is any combination of other diseases.
