Hypertension Management
For most adults with confirmed hypertension (BP ≥140/90 mmHg), immediately initiate combination pharmacological therapy with two first-line agents—preferably a RAS blocker (ACE inhibitor or ARB) combined with either a dihydropyridine calcium channel blocker or thiazide/thiazide-like diuretic as a single-pill combination—while simultaneously implementing comprehensive lifestyle modifications. 1, 2
Diagnosis and Confirmation
- Measure blood pressure using a validated device with the patient seated, arm at heart level, taking at least two readings per visit across multiple visits to confirm the diagnosis 1, 3
- Check standing blood pressure in elderly and diabetic patients to exclude orthostatic hypotension 1
- Consider ambulatory blood pressure monitoring when clinic readings show unusual variability, suspected white coat hypertension, or apparent treatment resistance 1, 3
- Calculate 10-year cardiovascular disease risk to guide treatment intensity, particularly for patients with borderline hypertension (systolic 130-139 mmHg or diastolic 80-89 mmHg) 1, 2, 3
Lifestyle Modifications (Foundation for All Patients)
Weight and Body Composition:
- Target BMI 20-25 kg/m² and waist circumference <94 cm in men, <80 cm in women 1, 2
- Weight loss reduces blood pressure and enhances medication efficacy 4, 5, 6
Physical Activity:
- Perform at least 150 minutes per week of moderate-intensity aerobic exercise (or 75 minutes of vigorous activity) 1, 2, 3
- Add low- to moderate-intensity resistance training 2-3 times per week 1, 2, 3
Dietary Modifications:
- Adopt Mediterranean or DASH dietary patterns emphasizing fruits, vegetables, fish, nuts, and unsaturated fatty acids 1, 3
- Restrict sodium intake by avoiding table salt and eliminating excessively salty processed foods 1, 3, 4
- Limit free sugar consumption to maximum 10% of energy intake and discourage sugar-sweetened beverages 1, 3
Alcohol and Tobacco:
- Limit alcohol to <100 g/week of pure alcohol (approximately 14 units/week for men, 9 units/week for women), with complete avoidance preferred for optimal health outcomes 1, 3
- Stop all tobacco use immediately and refer to smoking cessation programs 1, 3
Pharmacological Treatment Algorithm
Initial Therapy (BP ≥140/90 mmHg):
- Start with two-drug combination therapy immediately using a RAS blocker (ACE inhibitor or ARB) plus either a dihydropyridine calcium channel blocker OR a thiazide/thiazide-like diuretic (chlorthalidone or indapamide preferred over hydrochlorothiazide) 1, 2, 3, 4
- Prescribe as a single-pill fixed-dose combination to improve adherence 1, 2, 3
Exceptions to Combination Therapy:
- Patients aged ≥85 years 1
- Symptomatic orthostatic hypotension 1
- Moderate-to-severe frailty 1
- Elevated BP (systolic 120-139 mmHg or diastolic 70-89 mmHg) with concomitant indication for treatment 1
Escalation to Triple Therapy:
- If BP remains uncontrolled after 4 weeks on two-drug combination, escalate to RAS blocker + dihydropyridine calcium channel blocker + thiazide/thiazide-like diuretic, preferably as single-pill combination 1, 2, 3
Resistant Hypertension (Fourth-Line):
- Add spironolactone when BP remains uncontrolled on triple therapy 3
Beta-Blockers:
- Reserve for compelling indications: angina, post-myocardial infarction, heart failure with reduced ejection fraction, or heart rate control 1
- Combine with other major BP-lowering drug classes when indicated 1
Blood Pressure Targets
Standard Adult Targets (<65 years):
- Target systolic BP 120-129 mmHg and diastolic BP <80 mmHg if well tolerated 1, 2, 3
- This target reduces cardiovascular risk most effectively 1, 2
Older Adults (≥65 years):
High-Risk Populations (diabetes, CKD, established CVD):
Poorly Tolerated Treatment:
- Apply the "as low as reasonably achievable" (ALARA) principle when target of 120-129 mmHg cannot be tolerated 1
Special Population Considerations
Black Patients:
- Initial therapy should include a thiazide-like diuretic plus calcium channel blocker, or calcium channel blocker plus ARB 2, 3
- Note: The stroke reduction benefit of losartan in patients with left ventricular hypertrophy does not apply to Black patients 7
Chronic Kidney Disease:
- Include RAS blocker when albuminuria/proteinuria is present 2, 3
- Target systolic BP 120-129 mmHg for eGFR >30 mL/min/1.73m² 2, 3
Diabetes:
- Initiate treatment at BP ≥140/90 mmHg 2
- Target BP <130/80 mmHg 2, 3
- Losartan specifically reduces progression of diabetic nephropathy in type 2 diabetes with elevated creatinine and proteinuria 7
Heart Failure:
- Use RAS blockers, beta-blockers, and mineralocorticoid receptor antagonists for HFrEF 2, 3
- Consider SGLT2 inhibitors for HFpEF 3
Previous Stroke/TIA:
- Target systolic BP 120-130 mmHg 2, 3
- Use RAS blockers, calcium channel blockers, and diuretics as first-line agents 2
Coronary Artery Disease:
Critical Pitfalls to Avoid
- Never combine two RAS blockers (ACE inhibitor + ARB) as this increases adverse effects without additional benefit 1, 2, 3
- Do not rely on single blood pressure measurements for diagnosis; confirm with multiple readings across several visits 1, 3
- Do not overlook white coat hypertension—use ambulatory monitoring when office readings are persistently elevated despite apparent treatment 1, 3
- Do not neglect lifestyle modifications even when initiating pharmacotherapy; they are additive and may reduce medication requirements 1, 4, 8
- Do not use inadequate doses or inappropriate drug combinations; follow the evidence-based algorithm 2
Medication Timing and Adherence
- Take medications at the most convenient time of day to establish habitual patterns and improve adherence 1
- Single-pill fixed-dose combinations significantly improve adherence compared to multiple separate pills 1, 2, 3
- Employ multidisciplinary team approaches involving pharmacists to enhance adherence 2
