If a patient’s blood pressure suddenly rises to 190 mmHg, this is the time to first rule out the occurrence of acute cerebral hemorrhage or cerebral infarction. If it does not occur, blood pressure lowering treatment can be given first. Patients may be advised to take captopril or nifedipine controlled-release tablets to help lower blood pressure better. Other patients have high blood pressure themselves, but suddenly stop taking antihypertensive drugs recently, which can lead to a rebound increase in blood pressure. Other patients who are overly stressed, such as those with anxiety disorders and disorders in the regulation of vegetative nerves, may experience a sudden abnormal rise in blood pressure to 190 mmHg. Patients are advised to have ambulatory blood pressure monitoring if necessary, which helps to assess the overall blood pressure of the patient over a 24-hour period.
