What are the next management steps for an elderly woman with atherosclerotic heart disease, hypertension, hyperlipidemia, hypothyroidism, anxiety, insomnia, possible orthostatic hypotension, currently on lorazepam, metoprolol, hydrochlorothiazide, escitalopram, amlodipine, hydralazine, melatonin, and MiraLAX (polyethylene glycol 3350), with blood pressure ranging from normal to hypertensive?

Management of Uncontrolled Hypertension in an Elderly Woman with Atherosclerotic Heart Disease

This patient requires immediate optimization of her blood pressure regimen by maximizing her existing amlodipine dose to 10 mg daily before adding additional agents, while simultaneously addressing polypharmacy risks—specifically tapering lorazepam and evaluating the necessity of hydralazine—and screening for orthostatic hypotension given her multiple high-risk medications. 1

Critical Assessment Priorities

Blood Pressure Control Status

• Her systolic BP ranging 113-165 mmHg represents inadequately controlled hypertension, with peaks meeting Stage 2 criteria (≥160 mmHg) 2, 1
• Target BP for this elderly patient with atherosclerotic heart disease should be <140/90 mmHg as a minimum goal, with consideration of <130/80 mmHg if well-tolerated given her high cardiovascular risk 1, 3
• Avoid excessive diastolic BP lowering below 70-75 mmHg in patients with coronary disease to prevent compromised coronary perfusion 2

Orthostatic Hypotension Screening (Critical First Step)

• Measure BP after 5 minutes seated, then at 1 and 3 minutes after standing at every visit before any medication adjustments 1, 3
• This patient is at extremely high risk for orthostatic hypotension due to her combination of lorazepam, escitalopram, multiple antihypertensives, and advanced age 4, 5, 6
• Lorazepam specifically causes dose-related orthostatic symptoms through autonomic dampening, particularly problematic in elderly patients 6, 7
• Psychotropic agents (lorazepam, escitalopram) and cardiovascular drugs (metoprolol, hydrochlorothiazide, amlodipine, hydralazine) are all independently associated with orthostatic hypotension 5, 8

Immediate Medication Optimization

Step 1: Maximize Existing Calcium Channel Blocker

• Increase amlodipine from current dose to 10 mg daily (assuming she is on submaximal dosing), as this provides additional systolic BP reduction with good tolerability in elderly patients 1
• Uptitrating existing agents before adding a fourth class is preferred over multiple agents at subtherapeutic doses 1
• Dihydropyridine CCBs like amlodipine do not cause bradycardia and are well-tolerated in the elderly 1
• Reassess BP within 2-4 weeks of this adjustment 1, 3

Step 2: Address Problematic Polypharmacy

Lorazepam Taper (High Priority)

• Lorazepam should be gradually tapered and discontinued due to its contribution to orthostatic hypotension risk, fall risk, and cognitive impairment in elderly patients 4, 5, 6
• Benzodiazepines cause dose-related orthostatic symptoms through autonomic dampening, particularly dangerous when combined with multiple antihypertensives 6, 7
• Consider cognitive behavioral therapy for insomnia (CBT-I) as first-line insomnia management rather than chronic benzodiazepine use 6
• If anxiolytic therapy is essential, escitalopram alone may suffice for anxiety management without the added orthostatic risk of benzodiazepines 6

Hydralazine Evaluation

• Hydralazine is not a first-, second-, or third-line agent for hypertension in elderly patients and adds to polypharmacy burden 1
• Consider discontinuing hydralazine unless there is a compelling indication (e.g., severe heart failure with reduced ejection fraction) 1
• Hydralazine contributes to orthostatic hypotension risk as a vasodilator 4, 8

Step 3: Optimize Diuretic Therapy (If Needed After Step 1)

• If BP remains ≥140/90 mmHg after maximizing amlodipine, consider switching hydrochlorothiazide to a thiazide-like diuretic (chlorthalidone 12.5 mg or indapamide 1.25 mg daily) 1, 3
• Do NOT exceed chlorthalidone 12.5 mg in elderly patients, as higher doses (25-50 mg) increase hypokalemia risk 3-fold without meaningful additional BP reduction 1
• Chlorthalidone-induced hypokalemia <3.5 mEq/L eliminates cardiovascular protection and increases sudden death risk 1
• Monitor electrolytes (potassium, magnesium) within 2-4 weeks of any diuretic adjustment 1

Essential Comorbidity Management

Atherosclerotic Heart Disease

• Ensure statin therapy is optimized for secondary prevention, as statins provide similar relative risk reduction in elderly patients with higher absolute benefit due to elevated baseline risk 2
• Verify aspirin or alternative antiplatelet therapy is prescribed unless contraindicated 2

Hypothyroidism

• Confirm thyroid function is adequately treated, as uncontrolled hypothyroidism can worsen hypertension and hyperlipidemia 8

Hyperlipidemia

• Lipid-lowering therapy is a critical component of secondary prevention in elderly patients with atherosclerotic disease, with number-needed-to-treat lower than in younger patients 2

Lifestyle Modifications (Adjunctive to Pharmacotherapy)

• Implement DASH diet (rich in fruits, vegetables, low-fat dairy, low in saturated fat), which produces greater BP reductions in older adults than younger patients 2, 9
• Restrict dietary sodium to <2 g/day, particularly effective in elderly patients despite challenges with processed food reliance and age-related taste changes 2, 9
• Encourage weight reduction if overweight (target BMI 20-25 kg/m²), as weight loss produces larger BP reductions in older adults 2
• Promote regular physical activity appropriate for functional capacity 2
• Limit alcohol intake to <100 g/week 1

Monitoring Protocol

Short-Term (2-4 Weeks)

• Recheck BP in office with orthostatic measurements (seated and standing at 1 and 3 minutes) 1, 3
• Assess for symptoms of hypotension (dizziness, lightheadedness, falls, syncope) 8
• Check electrolytes if diuretic therapy is adjusted 1

Medium-Term (3 Months)

• Target BP control should be achieved within 3 months of treatment intensification 1, 3
• If BP remains uncontrolled on maximized amlodipine plus optimized diuretic, consider adding an ACE inhibitor or ARB as third-line therapy 1, 3

Long-Term (Annual)

• Schedule at least annual reviews of BP and cardiovascular risk factors once control is achieved 1
• Continue antihypertensive therapy lifelong, even beyond age 85, if well-tolerated 1

Critical Pitfalls to Avoid

• Do not add a fourth antihypertensive class before maximizing doses of existing agents 1
• Do not use beta-blockers (metoprolol) as sole therapy for hypertension in elderly patients, as they are less effective than CCBs or diuretics for stroke prevention 1
• Do not withhold treatment based on age alone; clinical trials demonstrate benefit in patients >80 years 1
• Do not ignore orthostatic hypotension screening in patients on multiple hypotensive medications 1, 5, 8
• Do not continue chronic benzodiazepine therapy without attempting taper and non-pharmacologic alternatives 6
• Do not use chlorthalidone doses >12.5 mg in elderly patients due to disproportionate electrolyte disturbance risk 1

Treatment Algorithm Summary

1. Screen for orthostatic hypotension (BP seated and standing) 1, 3
2. Maximize amlodipine to 10 mg daily 1
3. Initiate lorazepam taper with CBT-I referral 6
4. Discontinue hydralazine if no compelling indication 1
5. Reassess BP in 2-4 weeks 1
6. If BP ≥140/90 mmHg persists, optimize diuretic (switch to chlorthalidone 12.5 mg or indapamide 1.25 mg) 1, 3
7. If still uncontrolled, add ACE inhibitor or ARB as third-line agent 1, 3
8. Implement DASH diet and sodium restriction throughout 2, 9
