Treatment of Hypertension in Patients Over 40
Yes, you should administer antihypertensive drugs for patients over 40 with confirmed hypertension, initiating pharmacological treatment promptly when blood pressure is ≥140/90 mmHg regardless of cardiovascular risk, or at ≥130/80 mmHg after 3 months of lifestyle intervention if the patient has high cardiovascular disease risk (≥10% over 10 years). 1
Blood Pressure Thresholds for Drug Initiation
For patients with confirmed BP ≥140/90 mmHg:
- Initiate both lifestyle measures and pharmacological treatment promptly, irrespective of cardiovascular disease risk 1
- This reduces cardiovascular disease risk, stroke, and cardiac events 1
For patients with elevated BP (130-139/80-89 mmHg) and high CVD risk:
- After 3 months of lifestyle intervention, initiate pharmacological treatment if BP remains ≥130/80 mmHg 1
- High CVD risk is defined as ≥10% predicted 10-year risk 1
For patients with elevated BP and low/medium CVD risk (<10% over 10 years):
- BP lowering with lifestyle measures alone is recommended initially 1
Blood Pressure Targets
Target systolic BP of 120-129 mmHg in most adults to reduce CVD risk, provided treatment is well tolerated. 1
- This lower target reduces mortality, stroke incidence, and cardiac events compared to higher targets 1
- If the 120-129 mmHg target is poorly tolerated, apply the ALARA principle (as low as reasonably achievable) 1
First-Line Pharmacological Therapy
Initiate treatment with one of the following drug classes:
- Thiazide or thiazide-like diuretics (e.g., chlorthalidone, hydrochlorothiazide) 1, 2, 3
- ACE inhibitors (e.g., lisinopril, enalapril) 1, 4, 2
- Angiotensin receptor blockers (ARBs) (e.g., candesartan) 1, 2, 3
- Dihydropyridine calcium channel blockers (e.g., amlodipine, extended-release nifedipine) 1, 2, 3
All four classes have demonstrated efficacy in reducing cardiovascular morbidity and mortality 2, 3
Escalation Strategy
If BP is not controlled with a single drug:
- Add a second drug from a different class, preferably in a single-pill combination 1
- Preferred two-drug combinations include: RAS blocker (ACE inhibitor or ARB) + dihydropyridine CCB, or RAS blocker + thiazide/thiazide-like diuretic, or CCB + thiazide diuretic 1
If BP is not controlled with a two-drug combination:
- Increase to a three-drug combination: RAS blocker + dihydropyridine CCB + thiazide/thiazide-like diuretic, preferably in a single-pill combination 1
Critical pitfall to avoid:
- Never combine two RAS blockers (ACE inhibitor + ARB) together 1
Special Considerations for Age-Related Factors
For patients aged 40-60 years:
- Follow the general recommendations above 1
- Treatment reduces all-cause mortality, stroke, and cardiac events 2, 3
For patients aged 60-85 years:
- Treat according to the same guidelines as younger patients if not moderately to severely frail and treatment is well tolerated 1
- Before initiating or intensifying therapy, test for orthostatic hypotension (measure BP after 5 minutes sitting/lying, then 1 and/or 3 minutes after standing) 1
For patients aged ≥85 years or with moderate-to-severe frailty:
- Maintain BP-lowering treatment lifelong if well tolerated 1
- Consider treatment only from ≥140/90 mmHg in those with pre-treatment symptomatic orthostatic hypotension, clinically significant frailty, or limited predicted lifespan (<3 years) 1
- When initiating treatment, consider long-acting dihydropyridine CCBs or RAS inhibitors first, followed by low-dose diuretics if needed 1
Lifestyle Modifications (Concurrent with Pharmacotherapy)
Implement the following non-pharmacological interventions:
- Weight loss if overweight/obese 2, 3
- Dietary sodium reduction and potassium supplementation 2, 3
- DASH (Dietary Approaches to Stop Hypertension) diet pattern 1, 2
- Increased physical activity 2, 3
- Moderation or elimination of alcohol consumption 2, 3
These lifestyle modifications are partially additive and enhance the efficacy of pharmacological therapy 2
Monitoring and Follow-Up
Once BP is controlled and stable:
- Follow-up at least yearly for BP and other CVD risk factors 1
- Maintain treatment lifelong, even beyond age 85, if well tolerated 1
Important clinical consideration:
- Only 44% of US adults with hypertension have their BP controlled to <140/90 mmHg, highlighting the need for aggressive treatment and monitoring 2
