What is the recommended management for a patient with a blood pressure of 140/90 mmHg?

Management of Blood Pressure 140/90 mmHg

For a patient with confirmed BP of 140/90 mmHg, initiate combination pharmacological therapy immediately alongside lifestyle modifications, using a RAS blocker (ACE inhibitor or ARB) combined with either a calcium channel blocker or thiazide diuretic, preferably as a single-pill combination. 1

Initial Assessment and Confirmation

• Confirm the diagnosis with out-of-office BP measurements (home monitoring or ambulatory BP monitoring) to rule out white-coat hypertension, as office readings alone may overestimate true BP. 1, 2

• Assess cardiovascular risk using a validated risk calculator to determine 10-year CVD risk, though at BP ≥140/90 mmHg, pharmacological treatment is indicated regardless of calculated risk. 1

• Screen for secondary causes if the patient is under 40 years old (unless obese, in which case evaluate for obstructive sleep apnea first). 1

• Evaluate for target organ damage including:

  • Electrocardiogram for left ventricular hypertrophy
  • Serum creatinine and eGFR for kidney function
  • Urinalysis for albuminuria/proteinuria (though this is underutilized in practice) 3
  • Fundoscopy for hypertensive retinopathy (rarely performed but guideline-recommended) 3

Pharmacological Treatment Strategy

First-Line Therapy

Start with two-drug combination therapy rather than monotherapy, as this provides more effective BP control and faster achievement of target BP. 1

Preferred initial combinations: 1

• RAS blocker (ACE inhibitor OR ARB) PLUS dihydropyridine calcium channel blocker
• RAS blocker (ACE inhibitor OR ARB) PLUS thiazide or thiazide-like diuretic (chlorthalidone or indapamide)

Use fixed-dose single-pill combinations to improve adherence and simplify the regimen. 1

Exceptions to Combination Therapy

Consider starting with monotherapy only in: 1

• Patients aged ≥85 years
• Those with symptomatic orthostatic hypotension
• Moderate-to-severe frailty
• Elevated BP (120-139/70-89 mmHg) with specific compelling indications

Drug Class Considerations

• Thiazide and thiazide-like diuretics have the strongest evidence for reducing CVD events and are highly effective first-line agents. 1

• Beta-blockers should NOT be used as first-line therapy unless there are compelling indications such as angina, post-MI, heart failure with reduced ejection fraction, or need for heart rate control. 1

• Never combine two RAS blockers (ACE inhibitor + ARB together) as this increases harm without benefit. 1

• For black patients, prefer calcium channel blocker or thiazide diuretic as initial therapy (with or without a RAS blocker). 4

Blood Pressure Targets

Target systolic BP of 120-129 mmHg for most patients, provided treatment is well tolerated. 1

Target diastolic BP below 80 mmHg but not excessively low. 1, 2

Important Caveats on Targets

• The 2024 ESC guidelines recommend 120-129 mmHg as the optimal range, representing a shift toward more intensive control based on SPRINT trial data. 1

• First achieve BP <140/90 mmHg, then titrate toward the lower target of <130/80 mmHg while monitoring for adverse effects. 5

• Avoid excessive lowering below 120/70 mmHg, as post-hoc analyses suggest potential harm with overly aggressive reduction. 5

• If the patient cannot tolerate achieving 120-129 mmHg, use the ALARA principle ("as low as reasonably achievable") and target the lowest BP that avoids adverse effects. 1

Signs to Monitor That Indicate Excessive BP Lowering

Watch for: 5

• Orthostatic hypotension or dizziness
• Weakness or fatigue
• Rising serum creatinine
• Organ hypoperfusion symptoms

Lifestyle Modifications (Essential Concurrent Therapy)

Initiate immediately alongside medications: 1, 6

• Dietary changes: DASH diet or Mediterranean diet pattern
• Sodium restriction: Reduce intake to <2 g/day
• Potassium enhancement: Increase dietary potassium (unless contraindicated by CKD)
• Physical activity: 150 minutes/week of moderate aerobic exercise plus resistance training
• Weight loss: If overweight/obese, target 5-10% body weight reduction
• Alcohol reduction: Limit to ≤2 drinks/day for men, ≤1 drink/day for women
• Smoking cessation: If applicable

Escalation Strategy if BP Not Controlled

If BP remains uncontrolled on two drugs, escalate to three-drug combination: 1

• RAS blocker + dihydropyridine CCB + thiazide/thiazide-like diuretic
• Preferably as a single-pill combination

Medication Timing and Adherence

• Take medications at the most convenient time for the patient to establish a routine and improve adherence—there is no specific time of day that is superior. 1

• Lifelong treatment is required, even beyond age 85 years, if well tolerated. 1

Common Pitfalls to Avoid

• Do not delay pharmacological treatment at BP ≥140/90 mmHg waiting for lifestyle changes alone—start both simultaneously. 1

• Do not use monotherapy as initial treatment in most patients, as combination therapy is more effective. 1

• Do not undertreated due to fear of adverse effects—the cardiovascular benefits of achieving target BP far outweigh risks in most patients. 1

• Do not use beta-blockers as first-line unless compelling indications exist. 1

• Avoid overly aggressive acute lowering that causes symptoms of hypoperfusion. 5
