Hypertension is a medical condition in which the blood pressure is chronically elevated. As a physician, we are likely to 
have patients with hypertensive urgency and emergency. In the article below we provide you with an article which discussed all about hypertension regarding to the differences between Hypertensive Urgency and Emergency.
Accordingly, Hypertensive emergency or crisis hypertension is characterized by a severe elevation in blood pressure (> 180/120 mm Hg) complicated by evidence of impending or progressive target organ dysfunction. And Hypertensive Urgency is a severe elevation in blood pressure without progressive target organ dysfunction. It is a crucial step in distinguishing between hypertensive emergency and urgency for an appropriate management.
There are descriptions of etiology and pathophysiology, diagnosis, physical examination, laboratory testing, the management of both hypertensive condition (Neurologic emergency, Cardiac emergency, Hyperadrenergic states, Kidney failure). Also, you will be shown with sections such as causes of Hypertensive Emergency, Pathophysiology of hypertensive emergencies (click figure above), Parenteral Drugs Used for Treatment of Hypertensive Emergencies, and Drug of Choice in Treatment of Specific Types of Hypertensive Emergencies in brief and detailed figure and table.
Please refer to the original article of What is The Differences Between Hypertensive Urgency and Emergency that was written by Chirag K. Vaidya, MD and Jason R. Ouellette, MD from Yale University School of Medicine, New Haven, CT (source: turner-white.com).
