Treatment for Hypertensive Urgency

Definition and Management

Hypertensive urgency is defined as severe blood pressure elevation (typically >180/120 mmHg) in otherwise stable patients without acute or impending change in target organ damage or dysfunction, according to the American College of Cardiology and the American Heart Association 1, 2
The American College of Cardiology recommends distinguishing between hypertensive urgency and emergency by assessing for signs of target organ damage, such as hypertensive encephalopathy, intracerebral hemorrhage, acute myocardial infarction, acute left ventricular failure, unstable angina, aortic dissection, acute renal failure 1, 2
Patients with hypertensive urgency often present with symptoms like severe headache, shortness of breath, epistaxis, or severe anxiety, as reported in the Hypertension journal 3

The American College of Cardiology recommends reducing systolic blood pressure by no more than 25% within the first hour, and then cautiously reducing to normal during the following 24-48 hours, with a goal of reducing blood pressure to 160/100 mmHg within 2-6 hours 1, 4
The European Heart Journal suggests that short-acting nifedipine should NOT be used due to risk of rapid, uncontrolled blood pressure falls, and instead recommends using extended-release formulations 5
The American College of Cardiology advises against excessive falls in pressure that may precipitate renal, cerebral, or coronary ischemia, and recommends careful monitoring and follow-up to ensure continued blood pressure control 1, 2

The European Heart Journal recommends observing the patient for at least 2 hours to evaluate BP lowering efficacy and safety after initiating or adjusting medication, and arranging appropriate follow-up to ensure continued blood pressure control 6, 5
The American College of Cardiology emphasizes the importance of addressing medication compliance issues, which are often the underlying cause of hypertensive urgency, and providing adequate follow-up to ensure continued blood pressure control 1, 2

For patients with hypertensive urgency, defined as severe blood pressure elevation without acute target organ damage, the European Society of Cardiology recommends oral medication according to standard drug treatment algorithms with careful outpatient follow-up rather than hospital admission 7
Hypertensive urgency is distinguished from hypertensive emergency by the absence of acute microangiopathy, which typically presents with retinopathy, encephalopathy, acute heart failure, or acute renal deterioration, as noted by the European Heart Journal 7

The European Heart Journal recommends oral therapy with ACE inhibitors, ARBs, or beta-blockers for hypertensive urgency, using low initial doses due to potential sensitivity 7
For black patients with hypertensive urgency, initial treatment should include a diuretic or a calcium channel blocker, either alone or with a RAS blocker, as suggested by the European Heart Journal 8
The European Heart Journal advises caution with beta-blocker use in patients with acute and severe increases in blood pressure precipitated by sympathomimetics such as methamphetamine or cocaine 7
Many patients with acute pain or distress may have acutely elevated blood pressure that will normalize when pain and distress are relieved, rather than requiring specific intervention, as noted by the European Heart Journal 7

Rapid and uncontrolled or excessive blood pressure lowering is not recommended as it can lead to further complications, according to the European Heart Journal 7
Intravenous medications should be avoided in hypertensive urgency and are reserved for true hypertensive emergencies, as recommended by the American Heart Association and the American College of Cardiology 9, 10

Captopril is particularly useful in hypertensive urgencies associated with high plasma renin activity, and is contraindicated in pregnancy and bilateral renal artery stenosis, as recommended by the American Heart Association 11
Labetalol is contraindicated in reactive airways disease, COPD, second- or third-degree heart block, bradycardia, and decompensated heart failure, and may worsen heart failure, according to the American College of Cardiology 11, 12

The American Heart Association recommends that beta-blockers should be used with caution in sympathomimetic-induced hypertension 11, 12
