Guidelines on the choice of agents and how best to step up treatment for various subgroups in hypertension (high blood pressure) have changed over time and differ between countries. A Comparison of International Guidelines on Goal Blood Pressure and Initial Therapy for Adults With Hypertension (adapted from JNC 8 guidelines [ 1 ] )
Prehypertension is now referred to as "elevated blood pressure" by the American College of Cardiology (ACC) and the American Heart Association (AHA). [2] The ACC/AHA define elevated blood pressure as readings with a systolic pressure from 120 to 129 mm Hg and a diastolic pressure under 80 mm Hg, [3] Readings greater than or equal to 130/80 mm ...
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]
Multiple blood pressure readings (at least two) spaced 1–2 minutes apart should be obtained to ensure accuracy. [92] Ambulatory blood pressure monitoring over 12 to 24 hours is the most accurate method to confirm the diagnosis. [93] An exception to this is those with very high blood pressure readings, especially when there is poor organ ...
[25] [26] It was hoped that the research would help the AHA reach its goals of increasing cardiovascular health by 20% and reducing cardiovascular mortality by 20% by 2020. [26] In 2017, the American Heart Association, the American College of Cardiology, and nine other groups redefined high blood pressure for the first time in fourteen years. [27]

Blood pressure (BP) is the pressure of circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood through the circulatory system. When used without qualification, the term "blood pressure" refers to the pressure in a brachial artery, where it is most commonly measured.
The guideline acceptable reading also takes into account other co-factors for disease. Therefore, elevated blood pressure (hypertension) is variously defined when the systolic number is persistently over 140–160 mmHg. Low blood pressure is hypotension. Blood pressures are also taken at other portions of the extremities. These pressures are ...
