What is the initial management for a patient diagnosed with hypertension (HTN)?

Initial Management of Hypertension

The initial management for a patient diagnosed with hypertension should include both lifestyle modifications and pharmacological therapy with a combination of a renin-angiotensin system (RAS) blocker (ACE inhibitor or ARB) plus either a calcium channel blocker or a thiazide/thiazide-like diuretic, preferably as a single-pill combination. 1

Lifestyle Modifications

Lifestyle modifications are essential and should be implemented immediately:

• DASH diet: Reduces systolic BP by 3-11 mmHg 2
• Weight loss: Target healthy BMI; each kg lost reduces systolic BP by approximately 1 mmHg 2
• Sodium reduction: Limit to <2300 mg/day, can reduce systolic BP by 3-6 mmHg 2
• Physical activity: 30-60 minutes of moderate aerobic exercise 3-5 days/week (reduces systolic BP by 3-8 mmHg) 1, 2
• Alcohol moderation: Limit to ≤2 drinks/day for men and ≤1 drink/day for women 2
• Smoking cessation: Essential for overall cardiovascular risk reduction 2

Pharmacological Therapy

The 2024 European Society of Cardiology guidelines recommend:

1. Initial therapy: Two-drug combination for most patients with BP ≥140/90 mmHg 1

   • Preferred combination: RAS blocker (ACE inhibitor or ARB) + dihydropyridine calcium channel blocker or thiazide/thiazide-like diuretic
   • Fixed-dose single-pill combinations are recommended for better adherence

2. Medication selection considerations:

   • For African American patients: Consider starting with a calcium channel blocker or thiazide diuretic due to potentially reduced response to ACE inhibitors 1
   • For patients with diabetes, CKD, or proteinuria: ACE inhibitor or ARB is preferred 1
   • For women of childbearing potential: Avoid ACE inhibitors and ARBs due to teratogenic effects 1

3. Dosing: Start with low doses and titrate upward every 2-4 weeks until BP control is achieved 1, 3

   • Example: Lisinopril starting dose 10 mg daily, titrate to 20-40 mg daily as needed 3

Follow-up and Monitoring

• Monitor BP every 2-4 weeks until target is reached, then every 3-6 months 2
• Target BP: <140/90 mmHg for general population; <130/80 mmHg for high-risk patients (diabetes, CKD, CVD) 2
• If BP not controlled with a two-drug combination, increase to a three-drug combination (RAS blocker + calcium channel blocker + thiazide diuretic) 1
• If BP still not controlled, consider adding spironolactone 1

Common Pitfalls to Avoid

1. Monotherapy inadequacy: Starting with a single agent is often insufficient; most patients require at least two medications to achieve target BP 2, 4

2. Neglecting lifestyle modifications: Don't underestimate their impact; they can reduce the number and doses of medications needed 5

3. Inappropriate combinations: Avoid combining two RAS blockers (ACE inhibitor + ARB) due to increased adverse effects without additional benefit 1

4. Inadequate follow-up: Failure to monitor and adjust therapy frequently enough can lead to prolonged periods of uncontrolled hypertension 2

5. Medication non-adherence: Single-pill combinations improve adherence compared to multiple separate pills 1

By implementing both lifestyle modifications and appropriate pharmacological therapy from the outset, you can effectively manage hypertension and reduce the risk of cardiovascular events and mortality.
