Blood pressure of 120/60mmHg is normal, but the pulse pressure difference is relatively larger, which can be seen in older age, atherosclerosis, hyperthyroidism, anemia and other people. Normal blood pressure is systolic blood pressure less than 120mmHg and/or diastolic blood pressure less than 80mmHg, measured systolic blood pressure of 120mmHg, diastolic blood pressure of 60mmHg is normal. Systolic blood pressure minus diastolic blood pressure is equal to the pulse pressure difference, the normal pulse pressure difference is in the range of 30~40mmHg, systolic blood pressure 120mmHg minus diastolic blood pressure 60mmHg is equal to the pulse pressure difference of 60mmHg, which is relatively larger, it may be caused by the existence of poor vascular elasticity in the older population, degenerative changes in heart valves, etc., and it may be caused by the serious atherosclerosis, which results in the decline of the vascular elasticity and the increase of the pulse pressure difference. Decrease, the phenomenon of increased pulse pressure difference. In addition, diseases such as anemia and hyperthyroidism may also cause an increase in the pulse pressure difference. Measure your blood pressure regularly and consult a doctor if there is any abnormality.
