[ References ](#references-heading) The dangerous move in this case is to anchor on COPD because of the wheeze and miss the much deadlier physiology. A 78-year-old man with HFrEF, CKD, diabetes, and COPD arrives with three days of worsening dyspnea, orthopnea, edema, hypoxemia, rising creatinine, hyperkalemia, and a chest radiograph full of pulmonary vascular congestion. The ibuprofen history is not background noise. In an older patient with multimorbidity, an OTC medication can be the precipitant, the clue to the AKI, and the reason the usual home diuretic suddenly stops working. Reading the room ---------------- At the bedside, this is most consistent with acute decompensated heart failure with superimposed chronic lung disease rather than isolated COPD exacerbation. The exam and imaging say congestion first: orthopnea, bilateral edema, bibasilar crackles to the mid-zones, BNP elevation, and radiographic pulmonary edema. The wheeze and PaCO2 of 52 mmHg matter, but they do not erase the volume story. Clinically he is probably warm and wet rather than cold and wet, which matters because the immediate task is decongestion without tipping him into renal or hemodynamic collapse. Competing diagnosisWhy it stays or fallsAcute decompensated HFrEFFits orthopnea, edema, crackles, BNP, CXR, recent NSAID exposureCOPD exacerbationExplains wheeze and hypercapnia, but not the full congestive picturePneumonia, PE, ACSMust still be screened for if history, ECG, troponin, or imaging suggest them Why the OTC mattered -------------------- This is classic drug-precipitated cardiorenal decompensation. Heart failure guidance lists medications that increase sodium retention, including NSAIDs, among common precipitants of HF hospitalization. Kidney guidance also warns that NSAIDs reduce renal blood flow, can worsen CKD or cause AKI, and should be avoided in people with heart failure or in those taking ACE inhibitors/ARBs or diuretics. In practical terms, ibuprofen did three things at once here: it promoted sodium and water retention, blunted diuretic effectiveness, and worsened renal perfusion in a patient already dependent on a narrow hemodynamic balance. The rising creatinine and potassium are exactly what you expect when that balance breaks. [\[1\]](#cite-1 "Reference [1]") Early management ---------------- The first hour should be parallel processing, not sequential box-checking. Current HF guidance recommends assessing congestion and perfusion up front, identifying reversible precipitants, and giving prompt IV loop diuretics when significant fluid overload is present. Therapy should be titrated until clinical congestion resolves; if urine output and symptom relief are inadequate, intensifying the loop dose or adding a second diuretic is reasonable. In this patient, that means stopping ibuprofen immediately, starting IV loop diuresis, tracking urine output closely, and rechecking potassium and creatinine early rather than waiting for tomorrow morning labs. If respiratory distress persists, early CPAP or NIV is reasonable in acute heart failure with respiratory failure. Nitroglycerin can help dyspnea when blood pressure permits, but an SBP of 105 mmHg is the sort of number that should make you cautious rather than dogmatic. [\[1\]](#cite-1 "Reference [1]") > **Clinical Pearl:** In the older dyspneic patient with crackles, edema, and wheeze, do not let a COPD label distract you from dominant congestion. Treat the physiology that is most likely to kill the patient first. Medication review after stabilization ------------------------------------- Once oxygenation improves, the board-style lesson becomes medication strategy. HF guidance recommends addressing reversible factors, establishing euvolemia, and continuing or optimizing preexisting GDMT unless there is a real contraindication. It also explicitly cautions that mild worsening renal function or asymptomatic blood pressure reduction during HF hospitalization should not routinely trigger discontinuation of diuresis or other GDMT. In this case, however, the problem is not a trivial creatinine bump alone; potassium is 5.6 mmol/L. Temporary interruption of lisinopril is therefore reasonable as a context-specific inference, while bisoprolol is usually continued if perfusion remains adequate. Before discharge, the larger omission is chronic HFrEF optimization: the 2024 ACC pathway describes the core regimen as ARNI, evidence-based beta-blocker, MRA, and SGLT2 inhibitor, with beta-blocker titration deferred until the patient is compensated. [\[1\]](#cite-1 "Reference [1]") Creatinine interpretation also deserves more nuance than most exam stems allow. KDIGO highlights that in older adults with sarcopenia, creatinine-based eGFR can overestimate true kidney function, which can quietly lead to overdosing. The same guideline recommends medication review at every clinical encounter and especially at care transitions, specifically calling out the need to revisit dosing as GFR falls, including drugs such as metformin. So a creatinine of 145 µmol/L in a 78-year-old man is not reassuring merely because the number does not look dramatic. [\[2\]](#cite-2 "Reference [2]") His lingering proton pump inhibitor is a smaller but high-yield teaching point. A prescribing cascade occurs when an adverse drug effect is misread as a new disease and another medication is added; the AGA advises regular review of ongoing PPI indications and trial deprescribing when no definitive chronic indication remains. [\[3\]](#cite-3 "Reference [3]") Making discharge safer than admission ------------------------------------- This admission should end with a simpler regimen and a much clearer story. The ACC HFrEF pathway emphasizes regimen simplification, patient education, reminders, and pharmacist involvement to improve adherence. AHRQ supports the teach-back method for medication instructions, and pill organizers or pharmacy blister packaging can help selected older adults if the dispensing system is updated whenever prescriptions change. HF transitional care guidance also calls for clear discharge instructions, laboratory follow-up, a diuretic adjustment plan, communication with outpatient clinicians, and early follow-up, generally within 7 days. The highest-yield OTC instruction is explicit avoidance of ibuprofen, naproxen, and related NSAIDs unless a clinician who knows the patient’s HF and CKD says otherwise. [\[4\]](#cite-4 "Reference [4]") Clinical Application -------------------- - Ask about new OTC drugs every time HF and kidney function worsen. [\[1\]](#cite-1 "Reference [1]") - Do not stop GDMT reflexively for a small creatinine rise while the patient is still obviously congested. [\[1\]](#cite-1 "Reference [1]") - Interpret serum creatinine cautiously in older adults with low muscle mass. [\[2\]](#cite-2 "Reference [2]") - Discharge only with a written diuretic plan, teach-back confirmation, and early follow-up. [\[5\]](#cite-5 "Reference [5]") Key Points for Board Exams -------------------------- - **NSAIDs** are recognized precipitants of HF hospitalization and can worsen renal perfusion, sodium retention, and diuretic response. [\[1\]](#cite-1 "Reference [1]") - **IV loop diuretics** are first-line for hospitalized HF with significant fluid overload and should be escalated if decongestion is inadequate. [\[1\]](#cite-1 "Reference [1]") - **Mild renal deterioration alone** does not mandate stopping HF therapy, but true contraindications such as significant hyperkalemia change the decision. [\[1\]](#cite-1 "Reference [1]") - **Serum creatinine can underestimate CKD severity** in older adults with sarcopenia. [\[2\]](#cite-2 "Reference [2]") - **Prescribing cascade and legacy prescribing** should always be considered during medication reconciliation. [\[3\]](#cite-3 "Reference [3]") Conclusion ---------- The memorable lesson is not just that ibuprofen was a bad choice. It is that in older adults with HFrEF, CKD, and polypharmacy, acute decompensation is often medication-mediated, physiologically mixed, and preventable if you treat congestion aggressively while cleaning up the medication list.
