What are normal blood pressure values?

What are normal blood pressure values? According to the guidelines issued by the Italian Society of Hypertension (SIIA), systolic blood pressure should be below 140mmHg and diastolic blood pressure should be below 90mmHg in order to be considered normal. Slightly more restrictive cutoffs are used when blood pressure is measured at home, given that values measured in these conditions tend to be lower due to an absence of emotive aspects known as “white coat syndrome” (the typical increase in blood pressure due to the anxiety related to the presence of a doctor). According to international guidelines, blood pressure values measured at home should be below 135mmHg for systolic and below 85mmHg for diastolic blood pressure to be considered normal. Blood pressure values tend to be lower for women between 30 and 44 years of age. However, with age, blood pressure tends to rise quicker in women, to the point that for over 60s, prevalence of hypertension is greater in women. The linear relation between blood pressure and cardiovascular disease is similar across genders, with the exception of a lower incidence of coronary disease in pre-menopausal women.
