Antihypertensive Treatment for Patients Without Comorbidities

For patients without chronic kidney disease, diabetes, or heart failure, initiate treatment with any of the following first-line agents: thiazide/thiazide-like diuretics, ACE inhibitors, ARBs, or long-acting calcium channel blockers (CCBs), targeting blood pressure <140/90 mm Hg 1, 2.

Initial Therapy Selection

For the general hypertensive population without compelling indications:

  • Choose from four equally effective first-line options 2:

    • Thiazide or thiazide-like diuretics
    • ACE inhibitors
    • Angiotensin receptor blockers (ARBs)
    • Long-acting dihydropyridine calcium channel blockers

  • For Black patients specifically: Initiate with either a calcium channel blocker or thiazide-type diuretic as these show superior efficacy in this population 2

  • Most patients will require combination therapy to achieve target blood pressure 1. When monotherapy fails, add a second agent from the first-line options above.

Blood Pressure Targets

  • Standard target: <140/90 mm Hg for the general population 1, 2
  • More intensive target (<130/80 mm Hg) may be considered for patients at higher cardiovascular risk, though this remains based on expert opinion for those under 60 years 2, 3

Additional Medications for Specific Comorbidities

If Patient Has Chronic Kidney Disease (CKD)

Add an ACE inhibitor or ARB as the mandatory first agent 1, 4:

  • Target BP: <130/80 mm Hg (more stringent than general population) 1

  • For CKD with albuminuria (ACR ≥30 mg/mmol or ≥3 mg/mmol):

    • ACE inhibitor is first choice (Grade A evidence) 1
    • ARB if ACE inhibitor not tolerated (Grade B evidence) 1
    • Use maximum tolerated doses—benefits proven only at these doses 4

  • For CKD without significant albuminuria:

    • ACE inhibitor or ARB still reasonable but less strongly indicated 4

  • Add thiazide diuretics as second-line therapy 1

    • Switch to loop diuretics if eGFR <30 mL/min/1.73 m² or volume overload present 1

  • Consider SGLT2 inhibitors (dapagliflozin or empagliflozin) for patients with eGFR ≥20-25 mL/min/1.73 m²—these slow CKD progression independent of blood pressure effects 5, 6, 7

  • Avoid combining ACE inhibitor + ARB—this increases adverse events without additional benefit 1, 5

Monitoring requirements: Check creatinine and potassium within 2-4 weeks of starting or increasing RAS inhibitor doses 4. Continue therapy unless creatinine rises >30% within 4 weeks 4, 5.

If Patient Has Type 2 Diabetes

Initiate with ACE inhibitor or ARB, targeting BP <130/80 mm Hg 1, 5:

  • For diabetes WITH cardiovascular disease, kidney disease, or microalbuminuria:

    • ACE inhibitor or ARB is mandatory first choice (Grade A) 1

  • For diabetes WITHOUT the above complications:

    • Choose from: ACE inhibitors (Grade A), ARBs (Grade B), dihydropyridine CCBs (Grade A), or thiazide diuretics (Grade A) 1
    • ACE inhibitors/ARBs still preferred given additional renal benefits 8, 9

  • For combination therapy: When adding a second agent to an ACE inhibitor, prefer dihydropyridine CCB over hydrochlorothiazide (Grade A evidence from ACCOMPLISH trial) 1

  • Consider SGLT2 inhibitors for all patients with diabetes and hypertension—these provide cardiovascular and renal protection beyond glucose control 5, 6

  • Avoid alpha-blockers as first-line (Grade A recommendation against) 8

Important caveat: If systolic BP is ≥20 mm Hg above target or diastolic ≥10 mm Hg above target, consider starting with two first-line agents simultaneously, but exercise caution in elderly or those with autonomic neuropathy 1.

If Patient Has Heart Failure with Reduced Ejection Fraction (HFrEF)

Prioritize guideline-directed medical therapy (GDMT) for heart failure, which simultaneously treats hypertension 10, 11, 12:

Foundational Therapy (in order of initiation):

  1. ACE inhibitor (Grade A) 10, 11

    • Start low, titrate to maximum tolerated dose used in clinical trials
    • If ACE inhibitor not tolerated: Use ARB (Grade A) 10, 11
    • Consider switching to sacubitril/valsartan (ARNi) once stable on ACE inhibitor/ARB, but avoid if eGFR <30 mL/min/1.73 m² 13, 14

  2. Beta-blocker (Grade A) 10, 11

    • Use evidence-based agents: bisoprolol, carvedilol, or metoprolol succinate
    • Titrate to target doses from clinical trials

  3. Mineralocorticoid receptor antagonist (MRA) - spironolactone or eplerenone (Grade B for NYHA Class III-IV) 10, 11

    • Start low dose (12.5-25 mg daily)
    • Requires eGFR ≥30 mL/min/1.73 m² and potassium <5.0 mEq/L 13, 14

  4. SGLT2 inhibitor (dapagliflozin or empagliflozin)

    • Reduces heart failure hospitalizations and mortality
    • Safe with eGFR ≥20-25 mL/min/1.73 m² 12, 13, 14

Additional Antihypertensive Therapy if BP Remains Elevated:

  • Add diuretics as needed for volume control (loop diuretics preferred over thiazides in HFrEF) 10, 11

  • If further BP reduction needed: Add dihydropyridine CCB (amlodipine or felodipine) (Grade C) 11

    • Never use non-dihydropyridine CCBs (diltiazem, verapamil)—these worsen HFrEF due to negative inotropic effects 12

  • Hydralazine + isosorbide dinitrate if ACE inhibitors and ARBs both contraindicated (Grade B) 11

Target BP: <130/80 mm Hg, though optimal target in HFrEF remains uncertain 12. Prioritize uptitration of GDMT over adding additional antihypertensives.

Common Pitfalls to Avoid

  1. Do not underdose ACE inhibitors/ARBs—clinical trial benefits achieved only with maximum tolerated doses, not low doses 4, 9

  2. Do not stop RAS inhibitors for mild creatinine elevation (<30% increase) or mild hyperkalemia—use potassium binders or dietary modification instead 4, 5

  3. Do not combine ACE inhibitor + ARB—increases adverse events without benefit 1, 5

  4. Do not use non-dihydropyridine CCBs in HFrEF—harmful due to negative inotropic effects 12

  5. Do not withhold SGLT2 inhibitors due to modest eGFR decline—initial small decreases are expected and do not indicate harm 6, 7
