🎯 PREVENT-Guided Treatment Decisions
The 2025 guidelines fundamentally restructure treatment decisions using the PREVENT calculator
with the unified 7.5% threshold for Stage 1 hypertension, aligning cardiovascular risk reduction
strategies with statin therapy recommendations.
📊 Treatment Thresholds Using PREVENT
🎯 Unified 7.5% Risk Threshold
The 7.5% threshold represents deliberate alignment with statin therapy thresholds,
promoting unified cardiovascular risk reduction strategies.
Stage 1 HTN + PREVENT ≥7.5%
Class 1: Immediate medication
Stage 1 HTN + PREVENT <7.5%
Class 1: Medication after 3-6 month lifestyle trial
Stage 2 HTN
Class 1: Immediate dual therapy
🏗️ First-Line Agent Selection
First-line agent selection maintains thiazide-type diuretics, long-acting dihydropyridine calcium channel blockers, ACE inhibitors, and ARBs as Class 1 recommendations based on cardiovascular outcome trials.
💧 Thiazide-Type Diuretics
Preferred: Chlorthalidone over HCTZ for superior potency
Dosing
Chlorthalidone: 12.5-25 mg daily
Indapamide: 1.25-2.5 mg daily
HCTZ: 25-50 mg daily (less preferred)
✓ Advantages
- Excellent CV outcomes
- Low cost
- Synergistic
📋 Monitoring
- K+, Na+, Mg2+
- Creatinine
- Glucose, uric acid
🛡️ ACE Inhibitors / ARBs
RAAS Blockade: Preferred for diabetes, CKD, or HF
ACE Inhibitors
Lisinopril: 10-40 mg
Enalapril: 5-20 mg BID
Ramipril: 2.5-10 mg
ARBs
Losartan: 50-100 mg
Olmesartan: 20-40 mg
Telmisartan: 40-80 mg
⭐ Special Indications
Diabetic kidney disease
HFrEF
Post-MI
CKD
🔄 Calcium Channel Blockers
DHPs: Long-acting formulations preferred
Long-Acting DHPs
Amlodipine: 2.5-10 mg
Nifedipine XL: 30-90 mg
Felodipine: 2.5-10 mg
Non-DHPs
Diltiazem: 120-360 mg
Verapamil: 120-480 mg
Rate control option
💡 Clinical Pearls
- Excellent for isolated systolic HTN
- Safe in CKD • Monitor for edema
- Avoid immediate-release nifedipine
💓 Beta-Blockers
Reserved: Not first-line unless compelling indication
⭐ Compelling Indications
HFrEF
Post-MI
Angina / AFib rate control
Preferred Agents
Metoprolol XL: 25-200 mg
Carvedilol: 3.125-25 BID
Bisoprolol: 2.5-10 mg
⚠️ Limitations
- Less effective for stroke prevention
- Metabolic effects • Contraindicated in severe asthma
- May mask hypoglycemia
🤝 Combination Therapy Strategy
CLASS 1
Initial Dual Therapy for Stage 2 HTN
Combination therapy achieves target BP 6 months faster with fewer adverse events than sequential monotherapy titration.
🎯 Preferred Combinations
✓
ACEi/ARB + Thiazide
✓
ACEi/ARB + CCB
✓
CCB + Thiazide
📦 Single-Pill Combinations
20-25%
Better adherence vs separate tablets
- Simplified dosing regimens
- Cost-effective long-term
- Reduced pill burden
⚡ Clinical Advantages
⏱️ Faster time to goal BP
🔗 Synergistic mechanisms
✨ Fewer dose-related side effects
📈 Improved long-term outcomes
CLASS 3 HARM
🚫 Dual RAAS Blockade
Increased hyperkalemia, hypotension, and AKI without CV benefit (ONTARGET, ALTITUDE trials)
❌ Prohibited Combinations
✗
ACE inhibitor + ARB
✗
ACEi/ARB + Direct renin inhibitor
✗
Triple RAAS blockade
📊 Trial Evidence
ONTARGET
No CV benefit with dual blockade
ALTITUDE
Increased harm, trial stopped early

Treatment Recommendation
Based on current inputs, lifestyle modifications are recommended.
Preferred Initial Therapy:
Lifestyle modifications first
Target Blood Pressure:
<130/80 mmHg
🎯 Key Implementation Strategies
📊 PREVENT Integration
Use PREVENT calculator for all Stage 1 hypertension treatment decisions. The 7.5% threshold aligns with statin recommendations for unified cardiovascular risk reduction.
💊 Combination Priority
Start dual therapy for Stage 2 hypertension. Single-pill combinations improve adherence by 20-25% compared to separate tablets.
🎯 Goal Achievement
Achieve <130/80 mmHg in all high-risk patients. Consider intensive targets (<120 mmHg) only in carefully selected patients without contraindications.
