For years, the upper limit of normal blood pressure (BP) for all adults was 140 systolic pressure (SBP) over 90 diastolic pressure (DBP) mmHg. Higher numbers usually required treatment.
In medicine, systolic hypertension is defined as an elevated systolic blood pressure (SBP). [1] If the systolic blood pressure is elevated (>140) with a normal (<90) diastolic blood pressure (DBP), it is called isolated systolic hypertension. [2] Eighty percent of people with systolic hypertension are over the age of 65 years old. [3]
Many expert groups recommend a slightly higher target of 150/90 mmHg for those over somewhere between 60 and 80 years of age. [114] [115] [119] The JNC 8 and American College of Physicians recommend the target of 150/90 mmHg for those over 60 years of age, [14] [119] but some experts within these groups disagree with this recommendation. [120]
If systolic blood pressure is elevated (>140 mmHg) with a normal diastolic blood pressure (<90 mmHg), it is called isolated systolic hypertension and may present a health concern. [ 49 ] [ 56 ] According to the 2017 [ 57 ] American Heart Association blood pressure guidelines state that a systolic blood pressure of 130–139 mmHg with a ...
For example, if a person’s actual blood pressure is 134, and blood pressure is measured on a dangling arm, the reading could end up over 140, which is considered to be stage 2 hypertension.
For most people, recommendations are to reduce blood pressure to less than or equal to somewhere between 140/90 mmHg and 160/100 mmHg. [2] In general, for people with elevated blood pressure, attempting to achieve lower levels of blood pressure than the recommended 140/90 mmHg will create more harm than benefits, [3] in particular for older people. [4]
A minimum systolic value can be roughly estimated by palpation, most often used in emergency situations, but should be used with caution. [10] It has been estimated that, using 50% percentiles, carotid, femoral and radial pulses are present in patients with a systolic blood pressure > 70 mmHg, carotid and femoral pulses alone in patients with systolic blood pressure of > 50 mmHg, and only a ...
The variation in pressure in the left ventricle (blue line) and the aorta (red line) over two cardiac cycles ("heart beats"), showing the definitions of systolic and diastolic pressure Blood pressure is classified as normal blood pressure, prehypertension , hypertension (stages I and II), and isolated systolic hypertension , which is a common ...
