Hypertension: Target Blood Pressure Levels
Key Highlights from the Recommended Guideline
• Aim for a blood pressure < 140/90 mm Hg (< 130/80 mm Hg in patients with diabetes or renal disease)
• Prioritize control of systolic blood pressure, a much stronger cardiovascular risk factor than diastolic blood pressure
Scope: Health professionals involved in the care of adults who have or are at risk for hypertension
What are the benefits of lowering blood pressure? • Treat hypertension in order to reduce(1) stroke by 35%–40%; (2) myocardial infarction
by 20%–25 %, and (3) heart failure by >50 %. [Level of Evidence: M] What blood pressures should I aim for when treating my patients with hypertension?
• Aim for a target blood pressure < 140/90 mm Hg in most patients to decrease
cardiovascular complications. [Level of Evidence: RA] • Aim for <130/80 mm Hg in patients with diabetes or renal disease. [Level of
Evidence: PR] • Focus on systolic rather than diastolic blood pressure, because:
o Systolic blood pressure is a stronger cardiovascular risk factor than diastolic blood pressure in patients over 50 years old. [Level of Evidence: F]
o Poor control of systolic blood pressure is a key factor in poor overall blood
pressure control. [Level of Evidence: X, F]

Should I be concerned about “pre-hypertension” (120-129/80-89 mm Hg) in patients without diabetes or renal disease? Should I be concerned about “pre-hypertension” (120-129/80-89 mm Hg) in patients without diabetes or renal disease? • Be aware that patients with pre-hypertension are at high risk for developing frank
hypertension. [Level of Evidence: Not stated] • Be aware that patients with pre-hypertension are at high risk for developing frank
hypertension. [Level of Evidence: Not stated] • Aim to decrease the later development of hypertension. [Level of Evidence: Not
stated] • Aim to decrease the later development of hypertension. [Level of Evidence: Not
stated]
• Focus on lifestyle modifications to reduce the risk of later hypertension. [Level of Evidence: Not stated]
• Focus on lifestyle modifications to reduce the risk of later hypertension. [Level of Evidence: Not stated]
• Do not use antihypertensive drug treatment. [Level of Evidence: Not stated] • Do not use antihypertensive drug treatment. [Level of Evidence: Not stated]
