Flashcards in pulm. hypertension Deck (10):
1

def. pulm HT

- elevation of mean pulm art. pressure
- >25 mmHg
- caused y probs anywhere in pulm circulation

2

def. pulm. arterial hypertension

- narrowing of the small pulm arteries and arterioles
- lead to vasc. resisitance
- right heart >25mmHg, AND normal left heart

3

5 anatomic sites for PHT

1. pulm. artery
2. pulm arteriole
3. pulm caps
4. pulm veins
5. L heart

4

NICE classification

5 groups
1. arteriole (PAH) and veno-occlusive (PVOD)
2. left heart
3. resp diseases
4. pulm arterey
5. misc

5

what are features of PAH

- idiopathic
- genetic
- drug and toxin induced
associated with
- CT disease
- HIV
- portal HT

6

epi of PAH

- rare
- F>M
- low survivial if not treated

7

4 steps for diagnosis of pulm HT

1. resp and cardiac Sx
2. risk for PAH
- famHx, toxic drugs, CTD, HIV , liver disease
3. risk for other 4 types
4. physical findings of pulm HT

8

5 investigations of pulm HT

1. look for resp disease
- walk test, PFT, CXR
2. look for underlying predisposing causes
3. look for cardiac disease
- ECG
4. look for VTE disease
5. measue pulm. pressures

9

5 Tx for pulm HT

1. treat underlying cause if one
2. diuretics for R heart failure
3. O2
4. heart of lung transplant
5. specific vasodilator therapy for PAH

10

3 possible vasodilator therapies
