Blood pressure 160/112 mmHg requires retesting of blood pressure, normal retesting is not dangerous, abnormal retesting with complications is dangerous, good control reduces risk. Systolic blood pressure ≥140mmHg and/or diastolic blood pressure ≥90mmHg on 3 measurements not taken on the same day is diagnostic of hypertension. Blood pressure 160/112 mmHg is higher than normal blood pressure values, but a repeat blood pressure measurement is required to diagnose hypertension. If the repeat blood pressure is normal, the current blood pressure of 160/112mmHg may be due to emotional fluctuations, strenuous exercise, consumption of coffee and strong tea, etc., and the actual normal blood pressure may be normal, and the blood pressure can be retested regularly thereafter. If hypertension can be diagnosed after retesting, the blood pressure value belongs to grade 3 hypertension, which is more serious and requires medication such as metoprolol to control blood pressure. Poorly controlled blood pressure is prone to cardiovascular and cerebrovascular complications, such as cerebral hemorrhage and heart attack, which may be life-threatening, while well controlled blood pressure can greatly reduce the risk. Patients are advised to have their blood pressure checked again, and if the blood pressure is still abnormal, they should consult a doctor for further examination and treatment as prescribed by the doctor.
