Diagnosis and Management of Resistant Hypertension: A Review

Importance: Hypertension, defined as office systolic blood pressure (SBP) 130 mm Hg or greater and/or diastolic blood pressure 80 mm Hg or greater, affects 43.9% of women and 49.5% of men in the US. Approximately 19.7% of patients treated for hypertension have apparent resistant hypertension (blood pressure ≥130/80 mm Hg) despite using 3 or more antihypertensive medications, preferably a renin-angiotensin system blocker, a calcium channel blocker, and a thiazide-type diuretic, at maximally tolerated doses.

Observations: Approximately 10% of patients treated for hypertension have true resistant hypertension confirmed with home or 24-hour ambulatory blood pressure monitoring to exclude white-coat hypertension (approximately 37.5% of apparent resistant hypertension) and after excluding medication nonadherence (approximately 50%) and secondary hypertension such as primary aldosteronism (approximately 5%-25%). Conditions associated with resistant hypertension include obesity, diabetes, chronic kidney disease, and sleep apnea. Resistant hypertension is associated with increased risk of cardiovascular death vs controlled blood pressure at 5 years to 10 years (absolute risk increase, 10.3% [95% CI, 8.7%-12.1%]). Lifestyle modifications for resistant hypertension include a low-sodium diet (<1500 mg/d), reducing or avoiding alcohol, 150 min/wk or more of aerobic exercise, and weight loss. Illicit drugs (eg, cocaine) and medications that increase blood pressure (eg, nonsteroid anti-inflammatory drugs, serotonin-norepinephrine reuptake inhibitors) should be avoided. Sleep apnea should be treated when diagnosis is confirmed. Pharmacologic optimization includes use of combination tablets of antihypertensives; intensifying diuretic therapy by using chlorthalidone; and sequential addition of antihypertensive medications using evidence-based algorithms. In a meta-analysis of 20 studies (9 randomized clinical trials [RCTs] and 11 observational studies [331 participants]), use of antihypertensive therapies that combine 2 to 3 medications into a single formulation reduced SBP by -3.99 mm Hg (95% CI, -7.92 to -0.07) vs equivalent doses given separately. For patients with apparent or true resistant hypertension who have an estimated glomerular filtration rate of 45 mL/min/1.73 m2 or greater and a serum potassium level of 4.5 mmol/L or less, adding spironolactone (25-50 mg/d) compared with placebo lowers office SBP by -13.3 mm Hg (95% CI, -17.89 to -8.72 [4 RCTs]) and 24-hour ambulatory SBP by -8.46 mm Hg (95% CI, -12.54 to -4.38 [2 RCTs]) in a network meta-analysis of 24 RCTs (3485 patients with resistant hypertension). A meta-analysis of 10 RCTs (2478 participants) reported that compared with a sham procedure, catheter-based renal denervation, which disrupts the sympathetic nerves in the renal artery walls, decreased 24-hour ambulatory SBP by -4.4 mm Hg (95% CI, -6.1 to -2.7) and office SBP by -6.6 mm Hg (95% CI, -9.7 to -3.6).

Conclusions and relevance: True resistant hypertension affects 10% of patients treated for hypertension and is diagnosed after excluding white-coat hypertension, medication nonadherence, and secondary hypertension such as primary aldosteronism. First-line treatment includes lifestyle modifications, diuretic therapy with chlorthalidone, and combination tablets of antihypertensives. Spironolactone and renal denervation decrease blood pressure in patients with true resistant hypertension.

The results of this study suggest that patients with poorly controlled BP should be further evaluated for alcohol use disorders even if the brief screening questions are negative. James W. Mold, MD, MPH

Background: This cross-sectional study aimed to describe proportions of patients with indications of alcohol consumption using phosphatidylethanol (PEth), the Alcohol Use Disorders Identification Test (AUDIT), and its consumption-focused version (AUDIT-C), in relation to blood pressure (BP) control, overall and by sex.

Methods: A total of 270 hypertensive primary care patients (ICD-10: I10.9) were stratified into BP control groups: controlled (<140/90 mmHg), uncontrolled (≥140/90 mmHg), and apparent treatment-resistant hypertension (aTRH; ≥140/90 mmHg with ≥3 antihypertensive drugs). A randomized sample from each stratum was invited, baseline data were collected. Alcohol consumption using predefined categories for PEth and AUDIT, and hazardous use (PEth ≥ 0.122 µmol/L; AUDIT ≥ 8; AUDIT-C ≥ 5 for men, ≥4 for women), were analyzed in relation to BP control groups.

Results: Mean age was 67 ± 11 years; 42% were women. PEth indicated high and regular alcohol consumption in 6.4% of controlled, 5.3% of uncontrolled, and 19.2% of aTRH patients (controlled vs. aTRH, P = .027; uncontrolled vs. aTRH, P = .013). AUDIT showed no significant differences in hazardous use between BP groups (P = .865). AUDIT-C identified slightly higher proportions of hazardous use than PEth, across BP groups and sexes. No significant differences were found between BP groups for hazardous use by PEth (P = .339) or AUDIT-C (P = .150).

Conclusions: PEth revealed significantly higher alcohol use in the aTRH group, undetected by AUDIT. AUDIT-C and PEth identified more hazardous use than AUDIT, suggesting their potential to prompt alcohol-related discussions and support evidence-based hypertension care. PEth correlated more strongly with AUDIT-C than with AUDIT.
