In the past, it was thought that this “white coat hypertension” was only mental tension and that my blood pressure was still normal. Now it has been found that this “white coat hypertension” may be an intermediate state between normal blood pressure and apparently persistent hypertension that needs to be closely monitored. With the progress of research on the diagnosis and prevention of hypertension, white coat hypertension is receiving more and more attention. It is believed that it may be closely related to the patient’s stress and alertness reactions, weight, lipids, blood sugar, smoking, etc.: 1, the generation of white coat hypertension may be related to the “pressure stimulation” of the patient by the medical staff when measuring the pressure, in a particular place the tone of voice and emotion of the medical staff talking with the patient can affect the measured blood pressure value. 2, ambulatory blood pressure monitoring: this method is currently used to confirm the diagnosis of white coat hypertension. The 24h ambulatory blood pressure of patients with white coat hypertension is significantly lower than that of patients with persistent hypertension. 3, white coat hypertension patients with office systolic blood pressure > 140 mmHg and/or diastolic blood pressure > 90 mmHg, and daytime ambulatory blood pressure systolic blood pressure < 135 mmHg diastolic blood pressure < 80 mmHg; this also needs to be clinically verified and evaluated, clinical suspicion of pure office hypertension should be assisted by home blood pressure measurement or ambulatory blood pressure measurement to diagnose. Prevention 1.Prevent the main risk factors of hypertension, achieve a reasonable diet to reduce weight to limit alcohol consumption, and perform appropriate physical activity. 2, pay attention to the adjustment of lifestyle and prevent stress, correct treatment and try to relieve all kinds of psychological stress. 3, can use Chinese medicine to dredge the liver and regulate qi treatment, I also use Chinese medicine in the clinic to make tea.
