- Diastolic blood pressure (DBP) < 80 mm Hg and systolic blood pressure (SBP) ≥ 180 mm Hg is categorized as hypertensive emergency.
- Hypertensive emergency is characterized by extreme BP elevation with acute or progressing end-organ damage.
- Hypertensive urgency is characterized by extreme BP elevation without acute or progressing end-organ injury.
Pathophysiology of Hypertension
