Hypertensive Urgency vs Emergrncy

-Urgency: is increase in BP > 180 / 120 w/o any signs of target organ damage
-while emergency: is increase in BP > 180/120 w s/o target organ damage , like:

1. Flash pulm edema- do CXR
2. CVA: get CTB
3. renal failure: get BUN and Cr
4. Coronary ischemia/ infarction: get EKG and Cardiac Enzymes

Management:

 for Urgency:: goal is to decrease BP by 25% in next 24 hrs

While for Emergency : goal is to decrease BP by 10% in next 1 hr and 25 in next 3- 4 hrs

Pathophysiology:

High BP--cause damage to endothelium---> Decrease NO secretion---> further exacerbates BP

Also Due to Endothelin damage ---> there will be Capillary leakage --> causing Flash Pulm Edema
