A hypertensive urgency is a clinical situation in which blood pressure is very high (e.g., 220/125 mmHg) with minimal or no symptoms, and no signs or symptoms indicating acute organ damage. [1] [2] This contrasts with a hypertensive emergency where severely high blood pressure is accompanied by evidence of progressive organ or system damage. [1]
A hypertensive emergency is not based solely on an absolute level of blood pressure, but also on a patient's baseline blood pressure before the hypertensive crisis occurs. Individuals with a history of chronic hypertension may not tolerate a "normal" blood pressure, and can therefore present symptomatically with hypotension , including fatigue ...
