In 2000, it was estimated that approximately 1 billion people worldwide have hypertension, making it the most prevalent condition in the world. Approximately 60 million Americans suffer from chronic hypertension, with 1% of these individuals having an episode of hypertensive urgency. In<unk>  departments and clinics around the U.S., the prevalence of hypertensive urgency is suspected to be between 3-5%. 25% of hypertensive crises have been found to be<unk>  versus urgency when presenting to the ER. Risk factors for<unk>  include age, obesity, noncompliance to anti hypertensive medications, female sex, Caucasian race, preexisting diabetes or coronary artery disease, mental illness, and sedentary lifestyle. Several studies have concluded that African Americans have a greater incidence of hypertension and a greater morbidity and mortality from hypertensive disease than non-Hispanic whites, however hypertensive crises have a greater incidence in Caucasians. Although severe hypertension is more common in the elderly, it may occur in children (though very rarely), likely due to metabolic or hormonal dysfunction. In 2014, a systematic review identified women as having slightly higher increased risks of developing hypertensive crises than do men. With the usage of anti hypertensives, the rates of<unk> es has declined from 7% to 1% of patients with hypertensive urgency. 16% of patients presenting with<unk>  can have no known history of hypertension.
