Answer

With the advent of antihypertensive agents, the incidence of hypertensive emergencies in the United States has declined from 7% to approximately 1% of patients with hypertension. [2] In addition, the 1-year survival rate associated with this condition has increased from only 20% (prior to 1950) to a survival rate of more than 90% with appropriate medical treatment. [3]  Nonetheless, despite its relative rarity, the number of US emergency department (ED) visits for hypertensive emergency and the rate per million adult ED visits increased more than two-fold between 2006 and 2013.
