INTRODUCTION: Evaluation and management of markedly elevated blood pressure in the emergency department vary widely. Guidelines recommend repeated measurements in a calm setting and structured follow-up, discouraging acute interventions in asymptomatic patients without end-organ damage. OBJECTIVE: We retrospectively assessed blood pressure changes and laboratory parameters in older hypertensive patients during emergency care. The primary objective was to compare triage and discharge blood pressure and evaluate differences between discharge and prior renal function and electrolyte values. Secondary objectives included describing intravenous cannulation and length of stay. METHOD: This single-center retrospective study included 158 patients treated in 2024 for primary hypertension in a county hospital emergency department. Triage and discharge blood pressures were compared using paired tests, discharge serum creatinine, estimated glomerular filtration rate, and potassium were compared to values from the previous 6 months. RESULTS: Systolic blood pressure decreased from a median of 190 to 150 mmHg (p<0.001), diastolic from 92 to 80 mmHg (p<0.001). Estimated glomerular filtration rate (63.5 vs. 61.0 mL/min/1.73 m²) and creatinine (81 vs. 83 µmol/L) showed no significant change. Serum potassium declined slightly (-0.15 mmol/L; p = 0.003) without clinical relevance. Intravenous cannula was inserted in 97.5% of patients, median stay was 6.0 hours. DISCUSSION: The observed decline likely reflects proper measurement and observation effects, in the absence of end‑organ damage a non‑invasive, outpatient‑oriented approach appears appropriate. CONCLUSION: Most older adults presenting with hypertension did not have a true hypertensive emergency. Blood pressure dropped in many cases just by monitoring and without acute organ damage. The emphasis of the treatment should be on the correct measurement of blood pressure, managing the reversible causes, starting oral antihypertensive therapy, and making an outpatient follow-up appointment. Routine invasive interventions are generally not warranted in asymptomatic cases. Orv Hetil. 2025; 166(50): 1975-1982.
