Is an overweight elderly woman with uncontrolled hypertension (high blood pressure), tachycardia (elevated resting heart rate), and unexplained unilateral ankle edema, taking antihypertensive medications, suitable for balneotherapy in a Physical Medicine and Rehabilitation (PM&R) hospital with no access to other specialties?

Balneotherapy Suitability Assessment

This patient is NOT suitable for balneotherapy at a PM&R hospital without access to other specialties due to uncontrolled hypertension (150/85 mmHg), persistent tachycardia (97-107 bpm), and unexplained unilateral ankle edema requiring urgent cardiovascular and secondary hypertension evaluation. 1

Critical Safety Concerns

Uncontrolled Hypertension Requiring Specialist Referral

• The patient's BP of 150/85 mmHg represents uncontrolled hypertension despite being on antihypertensive medications. 1
• The 2024 ESC Guidelines explicitly recommend that patients with resistant or uncontrolled hypertension should be referred to specialized centers with expertise in hypertension management for further testing. 1
• Patients with suspected resistant hypertension require exclusion of pseudo-resistance (poor adherence, white-coat effect), secondary hypertension screening, and medication optimization—none of which can be adequately performed in a PM&R facility without access to other specialties. 1

Unexplained Tachycardia

• Resting heart rate of 97-107 bpm is abnormally elevated and requires investigation for underlying causes including hyperthyroidism, anemia, cardiac arrhythmias, or medication effects. 1
• This tachycardia combined with uncontrolled hypertension significantly increases cardiovascular risk and requires cardiology evaluation before any elective therapy. 1

Unilateral Ankle Edema Red Flags

• Unilateral ankle edema that is positional (resolves when lying down) but has persisted for 1.5 years is NOT adequately explained by a remote ankle fracture and requires vascular evaluation. 2, 3
• While the patient attributes edema to an old fracture, differential diagnoses that must be excluded include:
  • Deep vein thrombosis (DVT) or chronic venous insufficiency 3
  • Calcium channel blocker-induced edema (if patient is on amlodipine or similar dihydropyridine) 2, 4
  • Lymphatic obstruction 3
  • Occult malignancy causing venous compression 3
• The positional nature suggests venous insufficiency or medication effect rather than orthopedic sequelae alone. 2, 4

Why This Patient Needs Comprehensive Medical Evaluation First

Secondary Hypertension Screening Required

• The International Society of Hypertension recommends screening for secondary hypertension in patients with resistant hypertension, which includes renal artery stenosis, primary aldosteronism, sleep apnea, and renal parenchymal disease. 1
• Basic screening requires serum sodium, potassium, estimated glomerular filtration rate (eGFR), thyroid-stimulating hormone (TSH), and urinalysis—followed by aldosterone-to-renin ratio if indicated. 1
• Renal imaging (ultrasound) is recommended to assess for renovascular disease or structural abnormalities. 1

Medication Optimization Cannot Occur in Isolation

• Current guidelines recommend combination therapy with a renin-angiotensin system (RAS) blocker, calcium channel blocker, and thiazide/thiazide-like diuretic for uncontrolled hypertension. 1
• If the patient's unilateral edema is medication-induced (particularly from dihydropyridine calcium channel blockers), switching to an alternative agent or adding an ACE inhibitor can resolve edema while maintaining BP control. 2, 4
• This medication adjustment requires physician oversight with access to laboratory monitoring and cardiology consultation—unavailable in a standalone PM&R facility. 1

Cardiovascular Risk Stratification

• Uncontrolled hypertension with tachycardia places this patient at high risk for cardiovascular events including stroke, myocardial infarction, and heart failure. 1
• The 2024 ESC Guidelines recommend targeting systolic BP to 120-129 mmHg in most adults to reduce cardiovascular disease risk, which this patient is far from achieving. 1
• Balneotherapy involves thermal stress and hemodynamic changes that could precipitate acute cardiovascular events in an inadequately controlled hypertensive patient. 5

Balneotherapy Contraindications in This Context

Hemodynamic Effects of Thermal Water Therapy

• Balneotherapy involves immersion in thermal water, which causes peripheral vasodilation, increased cardiac output, and alterations in blood pressure—potentially dangerous in uncontrolled hypertension. 5, 6
• The buoyancy and temperature effects of mineral water can acutely lower blood pressure, but in a patient with labile hypertension and tachycardia, this creates risk for both hypertensive surges and hypotensive episodes. 5

Lack of Emergency Medical Support

• A PM&R hospital without access to cardiology, nephrology, or vascular surgery cannot manage acute complications such as hypertensive emergency, acute coronary syndrome, or DVT propagation. 1
• The 2017 ACC/AHA Guidelines define hypertensive emergencies as severe BP elevation (>180/120 mmHg) with target organ damage, requiring immediate medical intervention—this patient's baseline BP of 150/85 mmHg is precariously close to this threshold, especially given her claim that stress elevates it further. 1

Required Pre-Balneotherapy Workup

Before any consideration of balneotherapy, this patient requires:

1. Comprehensive hypertension evaluation at a specialized center including 24-hour ambulatory BP monitoring to confirm true resistant hypertension versus white-coat effect. 1

2. Secondary hypertension screening with aldosterone-to-renin ratio, renal ultrasound with Doppler, sleep apnea assessment, and thyroid function tests. 1

3. Vascular evaluation of unilateral ankle edema with venous duplex ultrasound to exclude DVT and assess for chronic venous insufficiency. 2, 3

4. Cardiology assessment including ECG, echocardiogram to evaluate for left ventricular hypertrophy or diastolic dysfunction, and Holter monitoring to characterize the tachycardia. 1

5. Medication optimization with target BP <130/80 mmHg achieved and maintained for at least 3 months before elective therapy. 1

6. Resolution or adequate explanation of unilateral edema with appropriate treatment (compression therapy for venous insufficiency, medication adjustment if drug-induced, or anticoagulation if thrombotic). 2, 4

Common Pitfalls to Avoid

• Do not accept the patient's self-diagnosis that BP elevation is "transient due to travel and stress"—this requires objective confirmation with ambulatory BP monitoring. 1
• Do not dismiss unilateral ankle edema as purely orthopedic without vascular imaging—this is a red flag for venous thromboembolism. 3
• Do not proceed with elective rehabilitation therapies when basic cardiovascular stabilization has not been achieved. 1
• Do not assume a PM&R facility can manage hypertensive complications—the 2024 ESC Guidelines explicitly state resistant hypertension requires specialized center referral. 1
