In hypertensive emergency with acute LV failure in the ED, how is it typically managed?

• A. Start oral antihypertensives and discharge home.
• B. Give IV beta-blocker only and monitor.
• C. Initiate IV antihypertensives to reduce MAP by about 20–25% in first hour; diuretics as indicated; ICU admission consideration.
• D. Give immediate thrombolysis.

Answer: (C)

In a hypertensive emergency with acute left ventricular failure, the priority is to rapidly and safely lower blood pressure while addressing the fluid overload that’s driving pulmonary edema. This is done with intravenous antihypertensives that allow careful titration, aiming to reduce the mean arterial pressure by about 20–25% in the first hour. After this initial reduction, BP can be lowered more gradually over the next hours to days to avoid underperfusing critical organs. Diuretics are added as indicated to relieve volume overload and improve pulmonary edema. Because this scenario involves ongoing organ stress, ICU-level monitoring and continued titration of therapy are often necessary.

Oral antihypertensives aren’t appropriate for this acute, life-threatening situation, and using IV beta-blocker alone without addressing preload/afterload can worsen LV failure. Thrombolysis isn’t indicated unless there’s a concurrent myocardial infarction with an appropriate indication.
