Resistant hypertension (RH) management involves assessing medication adherence and ruling out the white-coat effect. Effective treatment includes dietary sodium restriction, adequate diuretic therapy, and considering secondary causes.
Area of Science:
- Cardiology
- Nephrology
- Pharmacology
Background:
- Resistant hypertension (RH) is a significant clinical challenge, defined by uncontrolled blood pressure despite adherence to multiple antihypertensive medications.
- Accurate diagnosis requires ruling out medication non-adherence and the white-coat effect through out-of-office blood pressure monitoring.
- Lifestyle factors like obesity, alcohol intake, and dietary sodium significantly influence RH management.
Purpose of the Study:
- To outline the comprehensive evaluation and management strategies for patients with resistant hypertension.
- To highlight the importance of diuretic therapy and specific drug choices in RH treatment.
- To discuss secondary causes and advanced therapeutic options for refractory cases.
Main Methods:
- Review of current guidelines and evidence-based practices for resistant hypertension.
- Emphasis on diagnostic steps including adherence assessment and out-of-office BP monitoring.
- Discussion of pharmacological interventions, including diuretic selection and add-on therapies.
Main Results:
- Chlorthalidone demonstrates superior blood pressure-lowering effects and potential cardiovascular event reduction compared to hydrochlorothiazide.
- Loop diuretics are indicated for patients with a glomerular filtration rate below 30 mL/min.
- Spironolactone addition is an evidence-based strategy for RH, requiring careful potassium monitoring.
Conclusions:
- Optimal management of RH necessitates a stepwise approach, starting with adherence assessment and lifestyle modifications.
- Appropriate diuretic selection and the addition of mineralocorticoid receptor antagonists like spironolactone are crucial.
- Referral to a hypertension specialist is recommended for complex or refractory cases.
