70-year-old man, blood pressure in high pressure 160mmHg low pressure 90mmHg is not a normal physiological situation, if in the resting state, in the case of non-medication in the case of multiple measurements are still at this level, it is a hypertensive state.
Normal adults in the quiet state of high pressure in the normal range of 90 ~ 139mmHg, low-pressure normal range of 60 ~ 89mmHg, so the blood pressure in the high-pressure 160mmHg low-pressure 90mmHg, is not in the range of normal blood pressure, and belongs to the second level of hypertension.
However, since blood pressure is affected by a variety of factors such as heart rate, peripheral resistance, vascular volume, etc., if the blood pressure is measured under strenuous exercise or emotional stress, it will result in a high blood pressure. Therefore, blood pressure should be measured in a resting state and averaged over several measurements when no medication is taken to ensure the scientific accuracy of blood pressure measurements.
It is recommended to go to the hospital to find out whether the blood pressure is pathologically high, and to standardize the treatment under the guidance of the doctor to ensure a good prognosis.
