Systolic blood pressure (not standardized medical term: high pressure) 140mmHg, diastolic blood pressure (not standardized medical term: low pressure) 100mmHg is more serious. A systolic blood pressure of 140 mmHg and a diastolic blood pressure of 100 mmHg are classified as grade 2 hypertension according to our standardized blood pressure classification table, which can also be described as moderate hypertension. If there are no other risk factors and no other medical history, according to the cardiovascular risk stratification criteria for hypertensive patients, they can be diagnosed as medium-risk patients. If the combination of other risk factors or diabetes mellitus belongs to high-risk patients, so the systolic blood pressure of 140mmHg diastolic blood pressure of 100mmHg is more serious. The heart and blood vessels are the main organs damaged by high blood pressure, and long-term high blood pressure can promote the formation and development of atherosclerosis, which should be treated as soon as possible. If abnormal blood pressure measurement results occur, it is recommended to consult a doctor in time to clarify the cause of the disease with the help of a doctor, and to carry out targeted treatment or therapy.
