What is a major difference between ACC/AHA 2017 or later guidelines and older JNC guidelines regarding BP targets?

• A. JNC targets are generally <140/90.
• B. ACC/AHA guidelines generally set lower targets (e.g., <130/80 for many patients).
• C. ACC/AHA targets are higher than JNC targets.
• D. JNC guidelines recommend targets of <120/80.

Answer: (B)

Lower blood pressure targets in the ACC/AHA 2017 and newer guidelines are more stringent than in older JNC guidelines. The ACC/AHA approach aims for about 130/80 mmHg or lower for many adults, based on evidence that tighter control reduces cardiovascular events. In contrast, older JNC guidelines set higher targets, such as around 140/90 mmHg for most adults and even higher (e.g., 150/90) for some older patients. This shift reflects a move toward more aggressive BP management to lower overall cardiovascular risk, even though it may require more treatment in some individuals.
