A blood pressure reading of less than 120 mmHg systolic and 80 mmHg diastolic is normal for a 67-year-old woman, according to the National Institute on Aging. Blood pressure measuring at 140/90 or above, however, falls into the high category.
Adults are at risk of developing isolated systolic hypertension, according to the National Institute on Aging. This type of high blood pressure occurs when systolic pressure is 140 or higher, but diastolic pressure is less than 90.
High blood pressure is a common condition for older adults. According to NIH Senior Health, over 50 percent of American adults over 60 years old have high blood pressure. Physicians treat high blood pressure with medication and lifestyle changes.
