Systolic blood pressure and diastolic blood pressure are important indexes to evaluate blood pressure level and cardiovascular health. Systolic blood pressure refers to the highest blood pressure when the heart contracts, and diastolic blood pressure refers to the lowest blood pressure when the heart relaxes.
According to the standard of American Heart Association (AHA), normal blood pressure should be systolic blood pressure below 1.20 mmHg and diastolic blood pressure below 80mmHg. However, if systolic blood pressure and diastolic blood pressure belong to different grades, the following criteria are used as the basis:
Blood pressure is normal: systolic blood pressure is lower than 1.20 mmhg, and diastolic blood pressure is lower than 80mmHg. Normal hypertension: systolic blood pressure is between 120- 139mmHg and/or diastolic blood pressure is between 80-89mmHg. Essential hypertension: systolic blood pressure is between 140- 159mmHg and/or diastolic blood pressure is between 90-99mmHg.
Secondary hypertension: systolic blood pressure is between 160- 179mmHg and/or diastolic blood pressure is between 100- 109mmHg. Grade ⅲ hypertension: systolic blood pressure is higher than 180mmHg and/or diastolic blood pressure is higher than 1 10mmHg.
It should be noted that if systolic blood pressure and diastolic blood pressure belong to different grades, they should be evaluated separately according to AHA standard. For example, a person may have systolic blood pressure at normal blood pressure level (below 1.20 mmHg) and diastolic blood pressure at secondary hypertension level (90-99mmHg).
In this case, people's blood pressure is divided into normal blood pressure and secondary hypertension, so corresponding measures should be taken to reduce the diastolic blood pressure level to reduce the risk of cardiovascular diseases.
In addition, according to the recommendations of the World Health Organization (WHO), other factors such as age, sex, race, family history, smoking, obesity, diabetes, etc. It should be considered in the assessment of hypertension.
For example, aging is one of the risk factors of hypertension. Men are more likely to suffer from hypertension than women, and people with a family history of hypertension are more likely to suffer from hypertension. Smoking and obesity are also risk factors for hypertension. Therefore, when evaluating the blood pressure level, these factors should be considered comprehensively to determine the cardiovascular health status of individuals.
In a word, systolic blood pressure and diastolic blood pressure are important indexes to evaluate blood pressure level and cardiovascular health. If systolic blood pressure and diastolic blood pressure belong to different grades, they should be evaluated separately according to AHA standard, and other factors should be considered comprehensively to determine the cardiovascular health status of individuals.
In order to maintain a healthy cardiovascular state, people should pay attention to a balanced diet, moderate exercise, weight control, smoking cessation and alcohol restriction, and regular physical examination and health examination.
