What is the recommended treatment approach for a patient with mild hypertension?

Mild Hypertension Treatment Approach

For patients with mild hypertension (Grade 1: systolic 140-159 mmHg or diastolic 90-99 mmHg), initiate lifestyle modifications immediately and delay pharmacological treatment for 3-6 months if cardiovascular risk is low to moderate, but start drug therapy promptly if high cardiovascular risk factors are present. 1, 2

Risk Stratification Determines Treatment Timing

The decision to initiate drug therapy depends critically on total cardiovascular risk, not blood pressure alone:

• High/very high cardiovascular risk patients (diabetes, target organ damage like left ventricular hypertrophy, established cardiovascular disease, chronic kidney disease with proteinuria, or multiple risk factors): Start drug treatment immediately alongside lifestyle modifications 1

• Moderate cardiovascular risk patients (1-2 additional risk factors such as male sex, postmenopausal status, family history of premature cardiovascular disease, dyslipidemia): Delay drug treatment for several weeks while implementing lifestyle changes 1

• Low cardiovascular risk patients (Grade 1 hypertension without other risk factors): Delay drug treatment for 3-6 months, using lifestyle modifications alone during this observation period 1, 3

Comprehensive Lifestyle Modifications (First-Line for All Patients)

All hypertensive patients should receive intensive counseling on lifestyle changes, which can reduce blood pressure by 10-20 mmHg and may obviate the need for medications in mild hypertension: 1, 2

Weight Management

• Achieve and maintain body mass index 20-25 kg/m² 2
• Weight reduction provides 5-10 mmHg systolic reduction 2

Sodium Restriction

• Limit sodium intake to less than 2.3g (100 mEq) per day 1, 2, 4
• Eliminate table salt use and avoid processed foods 1
• Provides 5-10 mmHg blood pressure reduction 2, 3

Alcohol Limitation

• Men: ≤20-30g ethanol daily (≤14 units/week) 1, 2
• Women: ≤10g ethanol daily (≤8 units/week) 2
• Include alcohol-free days each week 1

Physical Activity

• Minimum 150 minutes moderate-intensity or 75 minutes vigorous-intensity aerobic exercise weekly 2
• Add resistance training 2-3 times per week 2
• Regular mild exercise (walking, jogging, cycling, swimming) for sedentary individuals 1

Dietary Pattern

• Follow DASH diet: rich in fruits (4-6 servings/400g daily), vegetables, whole grains, low-fat dairy products, polyunsaturated fats 1, 2, 3
• Reduce saturated fat and cholesterol intake 1
• Increase potassium intake through diet 1

Tobacco Cessation

• Stop all tobacco use immediately, as smoking independently causes cardiovascular disease 1, 2
• Consider nicotine replacement, bupropion, or varenicline for cessation support 1

When to Initiate Pharmacological Therapy

Start drug treatment immediately if: 1

• Blood pressure ≥180/105 mmHg (Grade 3 hypertension)
• Diabetes mellitus present
• Evidence of target organ damage (left ventricular hypertrophy, proteinuria, elevated creatinine, microalbuminuria)
• Established cardiovascular disease
• 10-year cardiovascular risk >30%

Start drug treatment after 3-6 months if: 1, 3

• Blood pressure remains ≥140/90 mmHg despite lifestyle modifications in Grade 1 hypertension
• Patient has moderate cardiovascular risk and blood pressure uncontrolled after several weeks

First-Line Pharmacological Options

When drug therapy is indicated, initiate with combination therapy rather than monotherapy for most patients: 2

Preferred initial combinations: 2

• ACE inhibitor or ARB + dihydropyridine calcium channel blocker (e.g., lisinopril + amlodipine)
• ACE inhibitor or ARB + thiazide/thiazide-like diuretic (e.g., lisinopril + hydrochlorothiazide)

Use fixed-dose single-pill combinations when possible to improve adherence 2

Monotherapy acceptable for: 2

• Grade 1 hypertension with low cardiovascular risk
• Blood pressure close to target (<150/95 mmHg)
• Elderly or frail patients

Blood Pressure Targets

• General target: 120-129/70-79 mmHg if well tolerated 2
• Minimum acceptable: <140/90 mmHg 1, 4
• Elderly patients (≥65 years): Systolic 130-139 mmHg 2

Critical Monitoring and Follow-Up

• Measure blood pressure on multiple occasions (≥2 readings per visit, multiple visits) before confirming diagnosis and treatment decisions 1
• Reassess within 4 weeks of any medication adjustment 2
• Confirm with home blood pressure monitoring (target <135/85 mmHg) or 24-hour ambulatory monitoring 2
• Check standing blood pressure in elderly patients and those with diabetes to detect orthostatic hypotension 1

Common Pitfalls to Avoid

• Do not delay treatment in high-risk patients: Waiting months for lifestyle modifications in patients with diabetes, target organ damage, or high cardiovascular risk increases morbidity and mortality 1

• Do not underestimate lifestyle modifications: These interventions are difficult to maintain long-term and require repeated reinforcement at each visit, but they enhance drug efficacy and may eliminate need for medications 1, 5

• Do not ignore secondary hypertension screening: In young patients (<40 years) or those with resistant hypertension, evaluate for secondary causes (primary aldosteronism, renal artery stenosis, obstructive sleep apnea) 2

• Do not use monotherapy in high-risk patients: Combination therapy achieves blood pressure control faster and more effectively 2

• Do not forget associated risk factor management: Address smoking cessation, dyslipidemia, and diabetes aggressively, as these multiply cardiovascular risk in hypertensive patients 1
