Out of curiousity, I'm researching the JNC 8 guidelines for hypertension, and when reading this publication, I noticed it says:
There is strong evidence to support treating hypertensive persons aged 60 years or older to a BP goal of less than 150/90 mm Hg and hypertensive persons 30 through 59 years of age to a diastolic goal of less than 90 mm Hg; however, there is insufficient evidence in hypertensive persons younger than 60 years for a systolic goal, or in those younger than 30 years for a diastolic goal, so the panel recommends a BP of less than 140/90 mm Hg for those groups based on expert opinion.
My question is: How can the JNC 8 recommend an overall BP goal (which consists of both diastolic and systolic measurements), yet, they don't suggest a goal for either diastolic, or systolic, depending on the age of the person? Why do they make this distiction?
