For patients with hypertension, a review at least once a month is recommended. First-episode hypertension is defined as a patient who has just discovered hypertension, comes to the cardiology clinic, and takes antihypertensive medication. For patients with first-episode hypertension, it is recommended that they should be reviewed once a week. Because hypertensive patients taking hypertension antihypertensive drugs will be recommended to monitor blood pressure and heart rate at home, and after the use of drugs, especially in the beginning of the use of drugs, the type of drugs and drug dose may be adjusted as they monitor their blood pressure. If the time is too long, the patient does not regularly monitor blood pressure, it may lead to two situations: 1, do not make adjustments after taking the medication, the blood pressure may not be well controlled, resulting in poor treatment; 2, after taking the medication leads to low blood pressure, often feel dizzy, but the patient believes that their blood pressure has been well controlled, they do not know that the blood pressure is low, there will be a risk. In patients with initial hypertension, monitoring is performed once a week. If the blood pressure is already well controlled, it can be reviewed once a month, mainly in fine tuning the medication and performing lifestyle management, including the disposition of exercise prescriptions. The management of hypertension is not only to keep blood pressure under control, but also to prevent heart, brain and kidney damage caused by hypertension. Therefore, patients should regularly monitor kidney function, and they should regularly monitor changes in electrocardiogram and even cardiac ultrasound.
