16
Q

treatment for CTEPH

A

anticoagulation and more common now is thromboendarterectomy

17
Q

CTEP follows acute PE in ___ %

A

3-4

18
Q

best screening test for PH

A

echo for estimation of PA pressures

19
Q

Gold standard in dx for PH

A

RHC

20
Q

most common PH gene associated

A

Bone morphogenic protein receptor that regulates vascular proliferation and when it is not workign there is dysregulation of proliferation and vascularization of smooth muscle cells

21
Q

what is important in the pathophysiology of PAH

A
  • increased TBX and ET1 which promote vasiconstriction
  • decreased in NO2 and PG12 that are vasodilators mediators
  • endothelial injury
22
Q

only group that responds to pharmalogical treatment

A

PAH- group 1

23
Q

what is the treatment for PAH

A

vasodilators or vasoconstrictors antagonist

  • PDE5 inhibitor
  • endothelin receptor antagonist
  • prostaglandins for vasodialtion
24
Q

how do we treat he other groups of PH?

A

treat underlying disease

25
Q

options for patient failing to respond to first line therapy

A
  • lung transplantation

- atrial septostomy

26
Q

PE is often missed

A

true

27
Q

is there increased dead space in PE?

A

yep

28
Q

how is hypoxemia related to PE

A

V/Q mismatch and shunt

29
Q

in massive PE what are the signs

A

increase in JVD

increase in P2, right heart strain

30
Q

virchow’s triad

A
  • stasis
  • inflammation
  • hypercoagulability
31
Q

westermark sign

A

sign of hypoperfusion and thus PE

32
Q

Hamptom’s hump

A

peripheral wedge-shaped infiltrate

33
Q

increased D-dimer helps in dx of PE?

A

nope, poor PPV

34
Q

wich pre-test proabability has high valifity

A

wells scoring system

35
Q

gold standard for PE dx

A

angiography

36
Q

systolic murmur that increases in intensity with inspiration

A

cavallo’s sign- tricuspid regurgitation

37
Q

clinical presentation ofr PAH

A
  • increased P2
  • carvallos
  • RV heave/ right-sided S3
  • JVD
