When Pills Are Not an Option: Procedural Pathways in a Case of Drug-Intolerant Resistant Hypertension

Introduction: Resistant hypertension is a complex clinical condition typically managed with combination pharmacotherapy. However, treatment becomes exceptionally challenging when standard antihypertensives are poorly tolerated. We report a unique case of a 79-year-old female with longstanding, poorly controlled hypertension who was intolerant to over 60 medications, including nearly every class of antihypertensives. Case Description: The patient presented with flash pulmonary edema and hypertensive emergency, requiring ICU admission. Her blood pressure on arrival exceeded 250 mmHg systolic. She had a 20-year history of uncontrolled hypertension and was labeled allergic to 61 medications.Only clonidine and propranolol were tolerated, offering limited control. Past imaging revealed 60% right renal artery stenosis. Despite her previous refusal of procedural interventions and multiple discharges against medical advice, she consented to care following this life-threatening episode. Laboratory studies showed AKI (Cr 1.3), troponin 1,500, BNP 500 (peaking at 2,000), and early sepsis markers. Workup for secondary causes of hypertension, including pheochromocytoma and coarctation, was negative. Bilateral renal artery stenting was performed without significant improvement in BP, The patient remained mostly asymptomatic post-stenting and was referred for renal denervation. Discussion: This case underscores the clinical dilemma of managing resistant hypertension in the context of extreme drug intolerance. Although some labeled allergies were later validated, others likely represented side effects misclassified as true allergies, emphasizing the need for cautious rechallenge strategies under supervision. Despite initial invasive intervention, BP remained unstable, warranting consideration of renal denervation. Emerging trials (e.g., SPYRAL HTN-OFF MED) suggest its utility in cases unresponsive to medications. This patient’s eventual procedural acceptance following acute deterioration highlights how crisis events can pivot patient behavior. Clinicians must remain flexible, recognizing that symptom burden does not always reflect hemodynamic severity, and that multidisciplinary, patient-centered approaches are vital in extreme presentations of resistant hypertension.
