In adults with HTN, does initiating
antihypertensive pharmacologic therapy at
specific BP thresholds improve health outcomes?
In adults with HTN, does treatment with
antihypertensive pharmacologic therapy to a
specified BP goal lead to improvements in health
outcomes?
In adults with HTN, do various antihypertensive
drugs or drug classes differ in comparative
benefits and harms on specific health outcomes?

Hypertension treatment for people with diabetes
Recommendations
Additonal considerations
Mandatory: initiate drug treatment in patients
with SBP ≥160 mmHg
• Strongly recommended: start drug treatment
when SBP ≥140 mmHg
SBP goals for patients with diabetes: <140 mmHg
DBP goals for patients with diabetes: <85 mmHg
All hypertension treatment agents are
recommended and may be used in patients with
diabetes
• RAS blockers may be preferred
• Especially in presence of preoteinuria or
microalbuminuria
Choice of hypertension treatment must take comorbidities into account
• Avoid in patients with diabetes
Coadministration of RAS blockers not
recommended
SBP, systolic blood pressure; DBP, diastolic blood pressure; RAS, renin–angiotensin system.

Hypertension treatment for people with nephropathy
Recommendations
Additonal considerations
Consider lowering SBP to <140 mmHg
Consider SBP <130 mmHg with overt proteinuria
• Monitor changes in eGFR
RAS blockers more effective to reduce
albuminuria than other agents
• Indicated in presence of microalbuminuria or
overt proteinuria
Combination therapy usually required to reach BP
goals
• Combine RAS blockers with other agents
Combination of two RAS blockers
• Not recommended
Aldosterone antagonist not recommended in CKD
• Especially in combination with a RAS blocker
• Risk of excessive reduction in renal function,
hyperkalemia

Goal BP for patients with DM
◦ Less than 140/80 mmHg
 ACCORD-BP trial
 HOT Trial
 Showed 51% reduction in major CV events in patients with DM
 Post-hoc analysis of small subgroup of the study (not pre-specified)
 Evidence graded as low quality by JNC8

Preferred Agents
◦ ACEi or ARB
 HOPE Study
 Included non-hypertensive patients
 Decreased risk of stroke with ACEi
◦ Despite conflicting evidence, continue to recommend
ACE/ARB first-line
 Cite high CVD risk and high prevalence of undiagnosed CVD in
patients with DM
