Management of Hypertensive Urgency

Assessment and Classification

• A patient with blood pressure of 170/110 mmHg and headache presents with hypertensive urgency, defined as severe BP elevation without evidence of acute target organ damage, according to the American Heart Association 1
• Hypertensive urgency is characterized by severe BP elevation (near or above 180/120 mmHg) without progressive target organ dysfunction, often presenting with symptoms like headache, as stated by the American College of Cardiology 2, 3

First-Line Management Approach

• The American Heart Association recommends oral antihypertensive medication as the appropriate first-line treatment for hypertensive urgency, with the goal of gradual BP reduction over 24-48 hours 2, 3
• Avoiding aggressive BP lowering is crucial, as it can precipitate renal, cerebral, or coronary ischemia, according to the European Society of Cardiology 2, 3

Medication Selection

• The European Society of Cardiology recommends a combination of a RAS blocker (ACE inhibitor or ARB) with either a calcium channel blocker or thiazide/thiazide-like diuretic as initial therapy for hypertensive urgency 4
• Short-acting nifedipine is no longer considered acceptable for hypertensive urgencies due to the risk of precipitous BP drops, as stated by the American College of Cardiology 2, 3

Monitoring and Follow-up

• The American Heart Association suggests monitoring BP frequently during the first few hours of treatment, with a target BP reduction of no more than 25% within the first hour, then to 160/100-110 mmHg within the next 2-6 hours 1, 2, 3
