Blood pressure diastolic (unstandardized medical terminology: low pressure) 105mmHg and systolic (unstandardized medical terminology: high pressure) 160mmHg are somewhat dangerous. A systolic blood pressure of 160mmHg and a diastolic blood pressure of 105mmHg is classified as grade 2 hypertension, which is moderate hypertension. Long-term high blood pressure can cause great damage to organs throughout the body. Long-term pressure increase will cause the heart of the left ventricle hypertrophy and expansion, but also promote atherosclerosis, may also make the cerebral blood vessels ischemia and degeneration, the most serious lead to cerebral hemorrhage, and the involvement of the kidneys will occur in chronic renal failure or even acute renal failure. So blood pressure diastolic pressure 105mmHg systolic pressure 160mmHg is a certain danger. High blood pressure should be lowered as soon as possible to reduce the incidence of cardiovascular and cerebrovascular disease and mortality. If the blood pressure measurement results are abnormal, it is recommended to consult a doctor in time, with the help of the doctor to clarify the cause of the disease, and to carry out targeted treatment or therapy.
