Hypertension Management in Adults

Blood Pressure Targets

For most adults with hypertension, aim for a blood pressure <130/80 mmHg. 1, 2 This target applies across the board—whether you have diabetes, chronic kidney disease, stable ischemic heart disease, or established cardiovascular disease. 1, 2

  • Patients with diabetes mellitus: Target <130/80 mmHg. 1, 2
  • Patients with chronic kidney disease (stage 3+ or albuminuria ≥300 mg/day): Target <130/80 mmHg. 1, 2
  • Patients with stable ischemic heart disease or prior myocardial infarction: Target <130/80 mmHg. 1, 2
  • Non-institutionalized adults ≥65 years: Target systolic <130 mmHg if tolerated. 1, 2

Critical Diastolic Consideration

  • In high-risk patients (especially those with coronary artery disease), do not lower diastolic pressure below 60–70 mmHg—excessive diastolic reduction may compromise coronary perfusion and increase adverse cardiovascular events. 2 The optimal diastolic range is 70–79 mmHg. 2

Step-by-Step Pharmacologic Management

Step 1: Confirm the Diagnosis

  • Hypertension requires an average of ≥2 readings on ≥2 separate occasions. 2
  • Before starting medication, confirm the diagnosis with out-of-office monitoring (home BP ≥135/85 mmHg or 24-hour ambulatory ≥130/80 mmHg) to exclude white-coat hypertension. 1, 2

Step 2: Classify Blood Pressure Stage

  • Stage 1 hypertension: 130–139/80–89 mmHg 1, 2
  • Stage 2 hypertension: ≥140/90 mmHg 1, 2

Step 3: Initiate Pharmacologic Therapy Based on Stage and Risk

Stage 1 Hypertension (130–139/80–89 mmHg)

  • Start medication if:

    • Established cardiovascular disease (prior MI, stroke, angina, heart failure, peripheral artery disease) OR 1, 2
    • 10-year ASCVD risk ≥10% (calculate with ACC/AHA Pooled Cohort Equations) OR 1, 2
    • Diabetes mellitus OR 1, 2
    • Chronic kidney disease (stage 3+ or albuminuria ≥300 mg/day) 1, 2
  • Begin with single-agent monotherapy from one of the four first-line classes (thiazide diuretic, ACE inhibitor, ARB, or long-acting dihydropyridine CCB). 1, 2

  • Titrate the dose upward before adding a second agent from a different class. 1, 2

Stage 2 Hypertension (≥140/90 mmHg or >20/10 mmHg above goal)

  • Start immediately with a two-drug combination from different first-line classes, preferably as a single-pill formulation. 1, 2, 3

  • Preferred two-drug regimens:

    • ACE inhibitor or ARB + thiazide diuretic 1, 2
    • ACE inhibitor or ARB + long-acting dihydropyridine CCB 1, 2
  • Single-pill combinations markedly improve adherence and persistence. 1, 2


First-Line Drug Class Selection by Population

General Adult Population (Non-Black, No Compelling Indications)

  • Thiazide diuretics—especially chlorthalidone 12.5–25 mg once daily—are the optimal first-line agents because they have the strongest cardiovascular outcome evidence from the ALLHAT trial (>50,000 participants). 1, 2
  • Chlorthalidone reduced heart-failure incidence by 38% versus amlodipine and stroke incidence by 15% versus lisinopril. 1, 2
  • Any of the four first-line classes (thiazide diuretic, ACE inhibitor, ARB, long-acting dihydropyridine CCB) may be selected, but thiazides have the most robust data. 1, 2

Black Patients Without Heart Failure or CKD

  • Start with a thiazide diuretic (chlorthalidone preferred) or a calcium-channel blocker. 1, 2
  • ACE inhibitors and ARBs are approximately 30–36% less effective for stroke prevention in Black patients because of lower renin activity. 1, 2
  • ARBs may be better tolerated than ACE inhibitors (less cough, less angioedema) but confer no additional cardiovascular benefit. 2

Patients with Diabetes Mellitus

  • Prefer an ACE inhibitor or ARB as initial therapy to protect renal function, especially when albuminuria ≥300 mg/day is present. 1, 2
  • Target BP <130/80 mmHg. 1, 2

Patients with Chronic Kidney Disease (Stage 3+ or Albuminuria)

  • ACE inhibitor or ARB is first-line to slow kidney disease progression and reduce proteinuria. 1, 2
  • Target BP <130/80 mmHg. 1, 2

Post-Myocardial Infarction or Stable Ischemic Heart Disease

  • Combine a β-blocker with an ACE inhibitor or ARB as foundational therapy. 1, 2
  • If angina persists and BP remains uncontrolled, add a dihydropyridine CCB. 1, 2
  • Continue β-blockers for at least 3 years post-MI; longer duration is reasonable for ongoing hypertension control. 2
  • Target BP <130/80 mmHg. 1, 2

Heart Failure with Reduced Ejection Fraction

  • Use a three-drug regimen: ACE inhibitor or ARB + β-blocker + diuretic. 1, 2

Escalation to Triple Therapy

  • If BP remains ≥140/90 mmHg (or above individualized target) after 3 months on a two-drug combination at optimal doses, add a third agent from the remaining first-line class. 2, 3
  • Standard triple regimen: ACE inhibitor or ARB + long-acting dihydropyridine CCB + thiazide diuretic, preferably as a single-pill combination. 2, 3
  • Optimize doses of the first two drugs before adding the third. 3

Lifestyle Modifications (Mandatory for All Patients with BP ≥120/70 mmHg)

  • Sodium restriction to <1,500 mg/day 2
  • DASH dietary pattern (high in fruits, vegetables, whole grains, low-fat dairy) 2
  • Weight reduction to achieve BMI <25 kg/m² 2
  • Aerobic exercise 90–150 minutes per week 2
  • Alcohol moderation (≤2 drinks/day for men, ≤1 drink/day for women) 2
  • Potassium supplementation 3,500–5,000 mg/day when not contraindicated 2
  • Smoking cessation 2

Lifestyle measures should be initiated simultaneously with pharmacologic therapy, not sequentially. 2, 3


Monitoring and Follow-Up

  • After initiating or adjusting medication, schedule monthly visits until the BP target is achieved. 1, 2, 3
  • Once at goal, follow up every 3–5 months for maintenance. 1, 2, 3
  • Dose adjustments should be spaced ≥4 weeks apart to allow full BP response. 2

Baseline Laboratory Evaluation

  • Obtain serum creatinine, estimated glomerular filtration rate (eGFR), potassium, fasting glucose or HbA1c, and lipid panel before starting therapy. 2

Laboratory Monitoring When Using ACE Inhibitors, ARBs, or Diuretics

  • Repeat creatinine, eGFR, and potassium within 1–2 weeks of initiation, after each dose increase, and annually thereafter. 2
  • An increase in serum creatinine of up to 50% above baseline or to 3 mg/dL (whichever is greater) is considered acceptable. 2

Out-of-Office Blood Pressure Monitoring

  • Systematic use of home BP monitoring (target <135/85 mmHg) or 24-hour ambulatory monitoring (target <130/80 mmHg) is essential to assess treatment response, detect white-coat effect, and identify masked uncontrolled hypertension. 1, 2

Agents to Avoid as First-Line

  • β-Blockers should not be used as first-line therapy in uncomplicated hypertension, especially in patients >60 years, because they are approximately 36% less effective than CCBs and 30% less effective than thiazides for stroke prevention. 1, 2

  • Reserve β-blockers for compelling indications: angina, post-MI, heart failure with reduced ejection fraction, or atrial fibrillation requiring rate control. 2

  • Alpha-blockers (e.g., doxazosin) are not first-line agents because they are less effective for cardiovascular disease prevention than thiazide diuretics; in ALLHAT, doxazosin was associated with an 80% higher rate of heart failure compared with chlorthalidone. 2


Critical Pitfalls to Avoid

  • Never combine an ACE inhibitor with an ARB (or add a direct renin inhibitor)—dual renin-angiotensin system blockade increases the risk of hyperkalemia and acute kidney injury without added cardiovascular benefit. 1, 2

  • Do not delay combination therapy in Stage 2 hypertension (≥140/90 mmHg)—starting with monotherapy increases cardiovascular risk. 1, 2

  • Do not lower diastolic pressure below 60 mmHg in high-risk patients (especially those with coronary artery disease)—excessive diastolic reduction may increase adverse cardiovascular events. 2

  • Do not rely on a single office measurement—improper technique can falsely raise readings by 10–30 mmHg; confirm with out-of-office monitoring. 2

  • Do not use hydrochlorothiazide doses <25 mg daily as monotherapy—such low doses are unproven or less effective in outcome trials. 2

  • Do not initiate clonidine as first-line therapy—it has significant CNS adverse effects (especially in older adults) and carries rebound hypertension risk; reserve it for resistant hypertension after failure of first-line agents. 4

  • Do not prescribe clonidine PRN for BP control—this creates life-threatening rebound hypertension risk. 4

  • If a patient is already taking clonidine, never abruptly discontinue it—taper gradually to prevent hypertensive crisis. 4


Special Populations

Pregnancy

  • Switch to methyldopa, extended-release nifedipine, or labetalol. 2
  • ACE inhibitors, ARBs, and direct renin inhibitors are absolutely contraindicated due to fetal toxicity. 2

Older Adults (≥85 years)

  • Continue BP-lowering treatment lifelong if well tolerated; asymptomatic orthostatic hypotension alone should not prompt drug withdrawal. 2
  • For older adults with high comorbidity burden or limited life expectancy, individualized clinical judgment and team-based risk-benefit assessment are reasonable. 2

Young Adults (<40 years)

  • Perform comprehensive screening for secondary hypertension causes: renal artery stenosis, primary aldosteronism, pheochromocytoma, Cushing syndrome, coarctation of the aorta. 2
  • In obese young adults, begin with obstructive sleep apnea evaluation. 2

Resistant Hypertension

Defined as BP ≥130/80 mmHg despite ≥3 antihypertensive agents at optimal doses (including a diuretic), or BP <130/80 mmHg requiring ≥4 agents. 2

Systematic Approach:

  1. Confirm true resistance by excluding white-coat effect with out-of-office monitoring and assessing medication adherence (non-adherence is the most common cause of apparent resistance). 2, 3

  2. Identify contributing lifestyle factors: obesity, excess alcohol intake, high sodium intake, NSAIDs, obstructive sleep apnea. 2

  3. Screen for secondary causes: primary aldosteronism (most common), renovascular disease, renal parenchymal disease, pheochromocytoma, Cushing syndrome. 2

  4. Optimize diuretic therapy—use loop diuretics in CKD (eGFR <30 mL/min). 2

  5. Add a mineralocorticoid-receptor antagonist (e.g., spironolactone 25–50 mg daily). 2

  6. Refer to a hypertension specialist if uncontrolled after 6 months. 2
