What should I do with a blood pressure reading of 135/99, indicating stage 1 hypertension?

Management of Blood Pressure 135/99 in a 39-Year-Old

For a blood pressure reading of 135/99 mmHg in a 39-year-old, you should start both lifestyle modifications and antihypertensive medication immediately as this represents Stage 2 hypertension with a diastolic pressure ≥90 mmHg. 1

Blood Pressure Classification

• Your reading of 135/99 mmHg falls into Stage 2 hypertension according to current guidelines (defined as systolic BP ≥140 mmHg or diastolic BP ≥90 mmHg) 1
• The elevated diastolic pressure (99 mmHg) is particularly concerning and requires prompt intervention 1

Immediate Actions

Confirm the Reading

• Take at least two more readings using a validated device with appropriate cuff size 1, 2
• Measure BP in both arms at the first visit; use the arm with the higher reading if there's a consistent difference 1

Start Treatment

• For Stage 2 hypertension (≥140/90 mmHg), immediate drug treatment is recommended alongside lifestyle interventions 1
• Do not delay pharmacological treatment as this level of BP elevation increases cardiovascular risk 1

Pharmacological Treatment

Initial Drug Selection

• For non-Black patients: Start with a low-dose ACE inhibitor or ARB (such as losartan) 1
• For Black patients: Start with a low-dose ARB plus dihydropyridine calcium channel blocker (DHP-CCB) or DHP-CCB plus thiazide-like diuretic 1
• Losartan is indicated for the treatment of hypertension in adults to lower blood pressure and reduce the risk of fatal and nonfatal cardiovascular events 3

Dosing and Titration

• Begin with low doses and titrate upward as needed 1
• Consider once-daily dosing and single-pill combinations to improve adherence 1
• If BP goal is not reached within 2-4 weeks, increase to full dose or add a second agent 1

Lifestyle Modifications (Start Immediately)

• Weight reduction if overweight/obese (target ideal body weight) 1, 4
• Adopt DASH diet (rich in fruits, vegetables, whole grains, low-fat dairy) 1, 5
• Sodium restriction to <1500 mg/day or at least a reduction of 1000 mg/day 1
• Increase potassium intake (3500-5000 mg/day) through diet 1
• Regular physical activity: 50-60 minutes of moderate exercise 3-4 times weekly 6
• Limit alcohol consumption (≤2 drinks/day for men, ≤1 drink/day for women) 1, 7
• Stress management techniques if stress is contributing to elevated BP 5

Blood Pressure Targets

• Target BP: <130/80 mmHg for most adults 1, 2
• Initial goal: Reduce BP by at least 20/10 mmHg 1
• Aim to achieve target BP within 3 months 1

Follow-up Plan

• Schedule follow-up within 2-4 weeks to assess response to therapy 2
• Monitor for medication adherence and side effects 1
• Consider home BP monitoring to track progress between office visits 1
• If BP remains uncontrolled despite multiple medications, refer to a specialist 1

Additional Testing to Consider

• Basic laboratory tests: electrolytes, creatinine, glucose, lipid profile 1
• Assess for target organ damage (e.g., ECG, urinalysis) 1
• Consider evaluation for secondary causes if BP is difficult to control 2

Common Pitfalls to Avoid

• Don't delay pharmacological treatment for Stage 2 hypertension 1
• Don't rely on a single BP measurement for diagnosis or treatment decisions 1
• Don't underestimate the importance of lifestyle modifications alongside medication 4, 8
• Monitor electrolytes and renal function 2-4 weeks after initiating ACE inhibitors or ARBs 1
