Managing Mild Hypertension: Cardiovascular Pharmacist Guidelines

Managing mild hypertension (systolic BP 140-159 mmHg, diastolic BP 90-99 mmHg) is a topic of ongoing debate. Recent data indicates that for every 128 patients treated for 5 years, one cardiovascular (CV) event is prevented.

📊 Experts contend that a 5-year period is insufficient to demonstrate significant benefits in low-risk patients. However, treating mild hypertension can potentially prevent the progression to severe hypertension and reduce the occurrence of additional CV events.

Adhere to hypertension treatment guidelines:

• Start with lifestyle interventions: Implement the DASH diet, promote regular exercise, and encourage weight loss.
• Sodium reduction: Reducing sodium intake by 1000 mg/day (about half a teaspoon of salt) can modestly lower BP. For more details, download the PDF guide from the Heart Failure Society of America (HFSA) titled "How to Follow a Low-Sodium Diet."

Escalate to antihypertensive medications if lifestyle modifications are insufficient or if patients have additional CV risks such as dyslipidemia or diabetes. Initiate treatment with a low-dose thiazide diuretic, ACE inhibitor, ARB, or calcium channel blocker. Avoid using beta-blockers as first-line therapy for uncomplicated hypertension due to less evidence of improved CV outcomes.

BP Goals:

• General patients: Aim for a BP target of < 140/90 mmHg.
• Diabetes patients: Target around 130/80 mmHg.
• Elderly patients: A systolic BP of about 150 mmHg is acceptable if needed to avoid diastolic BP < 60 mmHg.

Take-home points

Guidelines for managing mild hypertension with cardiovascular benefits..

1. Implement lifestyle changes like the DASH diet, regular exercise, and weight loss to manage mild hypertension effectively.
2. Reduce sodium intake by 1000 mg/day (about half a teaspoon of salt) to modestly lower blood pressure.
3. Initiate antihypertensive medications such as low-dose thiazide diuretics, ACE inhibitors, ARBs, or calcium channel blockers if lifestyle changes are insufficient.
4. Avoid beta-blockers as first-line therapy for uncomplicated hypertension due to less evidence of improving cardiovascular outcomes.
5. Aim for BP goals of < 140/90 mmHg in general patients, ~130/80 mmHg in diabetes patients, and systolic ~150 mmHg in elderly patients to prevent diastolic BP < 60 mmHg.
6. Stay updated with current hypertension management guidelines to ensure optimal patient care.
