Blood Pressure Management in Adults

Blood Pressure Targets by Age and Comorbidity

For most adults including those over 80 years, target a systolic blood pressure of 120–129 mmHg if tolerated, with a minimum acceptable goal of <140/90 mmHg. 1

Age-Stratified Targets

  • Adults 65–79 years: Target <130/80 mmHg for community-dwelling, noninstitutionalized individuals with average systolic BP ≥130 mmHg 1
  • Adults ≥80 years (functionally independent): Target 120–129 mmHg systolic if tolerated; minimum <140/90 mmHg 1
  • Adults ≥85 years: The same ≥140/90 mmHg threshold applies, and lifelong antihypertensive therapy should be maintained if well tolerated 1
  • Frail elderly (any age): Individualize targets based on tolerability, with a minimum target of <150/90 mmHg; consider monotherapy initially 1

Comorbidity-Specific Targets

  • Diabetes mellitus: Target <140/90 mmHg (not the stricter <130/80 mmHg), as the ACCORD trial showed no additional benefit of intensive lowering 1
  • Chronic kidney disease or cardiovascular disease: Target <140/90 mmHg if tolerated, potentially <130/80 mmHg for higher-risk patients 1, 2
  • African-American patients: Same targets apply; calcium channel blockers or thiazide diuretics are preferred first-line agents 3

First-Line Pharmacologic Therapy

Initiate combination therapy with a renin-angiotensin system (RAS) blocker (ACE inhibitor or ARB) plus either a dihydropyridine calcium channel blocker or a thiazide-like diuretic when BP ≥140/90 mmHg. 1

Preferred Initial Regimens

  • Standard dual therapy: ACE-I/ARB + calcium channel blocker (amlodipine 5–10 mg) or ACE-I/ARB + thiazide-like diuretic (chlorthalidone 12.5–25 mg or indapamide 1.25–2.5 mg) 1, 2
  • Elderly ≥85 years or frail patients: Start with monotherapy—preferably a dihydropyridine calcium channel blocker (amlodipine 2.5–5 mg daily)—and add a second agent only if needed 1
  • African-American or Hispanic patients: Calcium channel blocker or thiazide diuretic preferred over ACE-I/ARB due to lower renin activity 3

Medication Selection by Class

Drug Class First-Line Agent Starting Dose Maximum Dose Special Considerations
ACE Inhibitor Lisinopril 10 mg daily 40 mg daily Monitor K⁺ and creatinine at 1–2 weeks; avoid in pregnancy [1]
ARB Losartan 50 mg daily 100 mg daily Alternative to ACE-I if cough/angioedema; monitor K⁺ [1,3]
Calcium Channel Blocker Amlodipine 2.5–5 mg daily 10 mg daily Start low in elderly; well-tolerated; no bradycardia [1]
Thiazide-like Diuretic Chlorthalidone 12.5 mg daily 25 mg daily Preferred over HCTZ; monitor K⁺ at 2–4 weeks [1,4]
Thiazide-like Diuretic Indapamide 1.25 mg daily 2.5 mg daily Alternative to chlorthalidone [1]

Critical Medication Pitfalls

  • Beta-blockers are NOT first-line agents unless compelling indications exist (angina, post-MI, heart failure with reduced ejection fraction, atrial fibrillation) 1, 4
  • Never combine ACE-I + ARB (dual RAS blockade increases hyperkalemia and acute kidney injury without cardiovascular benefit) 1, 3
  • Avoid non-dihydropyridine calcium channel blockers (diltiazem, verapamil) in heart failure due to negative inotropic effects 3

Treatment Escalation Algorithm

Step 1: Dual Therapy (BP ≥140/90 mmHg on monotherapy)

  • Add a second agent from a different class (ACE-I/ARB + CCB or ACE-I/ARB + thiazide) 1, 2
  • Reassess BP within 2–4 weeks 1

Step 2: Triple Therapy (BP ≥140/90 mmHg on dual therapy)

  • Add the third agent to create ACE-I/ARB + calcium channel blocker + thiazide-like diuretic 1, 3, 4
  • This combination targets three complementary mechanisms: RAS blockade, vasodilation, and volume reduction 3
  • Achieves control in >80% of patients 3

Step 3: Resistant Hypertension (BP ≥140/90 mmHg on optimized triple therapy)

Add spironolactone 25–50 mg daily as the preferred fourth-line agent. 1, 4

  • Provides additional reductions of approximately 20–25 mmHg systolic and 10–12 mmHg diastolic 4
  • Monitor serum potassium and creatinine 2–4 weeks after initiation (hyperkalemia risk with concurrent ACE-I/ARB) 4
  • Alternative fourth-line agents if spironolactone contraindicated: amiloride, eplerenone, doxazosin, or beta-blocker (if compelling indication) 3

Before Adding Any Medication

  1. Verify medication adherence (most common cause of apparent resistance) 1, 4
  2. Confirm true hypertension with home BP monitoring (≥135/85 mmHg) or 24-hour ambulatory monitoring (≥130/80 mmHg) 1, 3
  3. Review interfering substances: NSAIDs, decongestants, oral contraceptives, systemic corticosteroids, stimulants, herbal supplements (ephedra, licorice) 3, 4
  4. Screen for secondary hypertension if BP ≥160/100 mmHg despite triple therapy: primary aldosteronism, renal artery stenosis, obstructive sleep apnea, pheochromocytoma 3, 4

Lifestyle Modifications (Adjunct to Pharmacotherapy)

Comprehensive lifestyle modification can lower systolic/diastolic BP by 10–20 mmHg and enhances the efficacy of all antihypertensive classes. 1, 2

Intervention BP Reduction Implementation
Sodium restriction 5–10 mmHg systolic <2 g/day (≈5 g salt) [1,2]
DASH dietary pattern 11.4/5.5 mmHg High in fruits, vegetables, whole grains, low-fat dairy; low in saturated fat [1,3]
Weight loss 6.0/4.6 mmHg per 10 kg Target BMI 20–25 kg/m² [1,2]
Aerobic exercise 4/3 mmHg ≥30 min most days, ≈150 min/week moderate intensity [1,2]
Alcohol limitation Variable ≤2 drinks/day (men), ≤1 drink/day (women); <100 g/week [1,3]

Monitoring and Follow-Up

Initial Monitoring (First 2–4 Weeks)

  • Recheck BP 2–4 weeks after any medication change 1, 2
  • Serum potassium and creatinine 1–2 weeks after starting ACE-I/ARB or thiazide diuretic 1, 4
  • Orthostatic BP (measure after 5 min seated, then at 1 and 3 min standing) in elderly patients 1

Ongoing Monitoring

  • Target achievement: Reach goal BP within 3 months of therapy modification 1, 2
  • Electrolytes and renal function: Every 3–6 months on chronic diuretic therapy 3
  • Annual reviews of BP and cardiovascular risk factors once controlled 1

Acceptable Creatinine Rise

  • Up to 20% increase in serum creatinine after starting ACE-I/ARB is acceptable and does not indicate progressive renal damage 1

Special Populations

Patients ≥85 Years

  • Do NOT withhold treatment based on age alone; ESC 2024 explicitly recommends continuation beyond 85 years when tolerated 1
  • Initiate therapy when office BP ≥140/90 mmHg 1
  • Start with monotherapy (dihydropyridine CCB preferred), add second agent if needed 1
  • If achieving 120–129 mmHg systolic is not feasible, adopt "as low as reasonably achievable" (ALARA) principle 1

Frail Elderly

  • Screen for moderate-to-severe frailty using validated tools 1
  • Treatment threshold remains ≥140/90 mmHg, but target BP may be set less aggressively 1
  • Consider monotherapy initially to minimize adverse effects 1
  • Assess for symptomatic orthostatic hypotension before intensifying therapy 1

African-American Patients

  • Calcium channel blocker or thiazide diuretic preferred over ACE-I/ARB as initial therapy 3
  • Combination of CCB + thiazide may be more effective than CCB + ARB 1, 3

Patients with Diabetes

  • Target <140/90 mmHg (not <130/80 mmHg) based on ACCORD trial 1
  • SGLT2 inhibitors recommended for diabetic patients with hypertension and CKD (eGFR >20 mL/min/1.73 m²); modestly lower BP and improve cardiovascular outcomes 1

Patients with Chronic Kidney Disease

  • ACE-I or ARB preferred for renoprotection 1, 3
  • Monitor for hyperkalemia and acute kidney injury 3
  • If CrCl <30 mL/min, loop diuretics (furosemide, torsemide) may be required instead of thiazides 3

Patients with COPD/Asthma

  • Calcium channel blockers and ARBs are safe and do not provoke bronchoconstriction 3
  • Beta-blockers are contraindicated unless compelling cardiac indication exists 3

Common Pitfalls to Avoid

  1. Do NOT delay treatment intensification when BP remains ≥140/90 mmHg; prompt action within 2–4 weeks is required 1, 4
  2. Do NOT add beta-blocker as second or third agent without compelling indication (less effective for stroke prevention) 1, 4
  3. Do NOT combine ACE-I + ARB (dual RAS blockade) 1, 3
  4. Do NOT increase monotherapy dose as primary strategy; combination therapy is more effective 1, 3
  5. Do NOT assume treatment failure without confirming adherence and excluding white-coat hypertension 1, 4
  6. Do NOT withhold treatment based on chronological age alone; base decisions on functional status and frailty 1
  7. Do NOT use chlorthalidone >25 mg in elderly (markedly increases hypokalemia risk without additional BP benefit) 1, 3
  8. Do NOT use thiazide diuretics in elderly patients with urinary incontinence (exacerbates nocturia and urgency) 3

Dose Optimization Principles

Chlorthalidone Dosing in Elderly

  • Start 12.5 mg daily; titrate to 25 mg daily if needed after 2–4 weeks 1, 4
  • Doses >25 mg significantly increase hypokalemia risk (3-fold) without meaningful additional BP reduction 1
  • Chlorthalidone-induced hypokalemia <3.5 mEq/L eliminates cardiovascular protection and increases sudden death risk 1

Losartan Dosing

  • Maximum effective dose for hypertension is 100 mg daily; doses above this (e.g., 150 mg) do not provide additional BP benefit 1

Amlodipine Dosing in Elderly

  • Start 2.5–5 mg daily; titrate gradually to 10 mg daily to minimize vasodilatory side effects 1
  • Elderly patients demonstrate equivalent or superior BP reductions with good tolerability 1
