Symptoms of PH
• Dyspnea
• Syncope
• Dizziness
Fatigue
Edema
Chest Pain
Non-specific nature of complaint can lead to:
• Confusion with other conditions
• Delayed diagnosis
Gaine et al. The Lancet, 1998. 352; 719
W.H.O. Functional Classification
Class I: Patients with PH but without resulting limitation of physical activity.
Ordinary physical activity does not cause undue dyspnea or fatigue, chest
pain or near syncope.
Class II: Patients with PH resulting in slight limitation of physical activity.
They are comfortable at rest. Ordinary physical activity causes undue
dyspnea or fatigue, chest pain or near syncope.
Class III: Patients with PH resulting in marked limitation of physical activity.
They are comfortable at rest. Less than ordinary physical activity causes
undue dyspnea or fatigue, chest pain or near syncope.
Class IV: Patients with PH with inability to carry out any physical activity
without symptoms. These patients manifest signs of right heart failure. They
are comfortable at rest. Dyspnea and/or fatigue may even be present at rest.
Discomfort is increased by any physical activity. (Syncope)

HIV
Epidemiology
0.5% prevalence– no decline since HAART
Occurrence depends upon length of infection, not CD4 count or prior opportunistic infections
Portopulmonary Hypertension
Epidemiology
-2-6% prevalence in cirrhotics, higher in liver transplant candidates (8%)
-Risk increases with duration of portal hypertension
-High cardiac flow states and LV diastolic dysfunction complicate PH

Cardiac Catheterization Evaluation for
Pulmonary Artery Hypertension
o Right heart catheterization only
Diagnostic,
To detect PAH at rest
o Right heart catheterization with exercise
(PA mean <= 25 mmHg and Pcw<=18 mmHg)
Diagnostic,
To detect PAH with exercise
o Exercise challenge
o Right heart catheterization
(PA mean > 25 mmHg and Pcw <= 18mmHg):
Assess vasodilator
responsiveness
o inhaled NO protocol
o Right heart catheterization with
(PA mean >25 mmHg and 12< Pcw <= 18 mmHg)
To assess for occult diastolic
diastolic dysfunction in PH
o Exercise or NS fluid challenge
o Right heart catheterization with “O2 sat run”
Assess for shunt
o Left heart catheterization
o Measure LVEDP
(At discretion of cath physician)
To confirm Pcw accuracy

Projects
• ISWT - PAH
– retrospective: ongoing
– prospective: needs design
– other groups, e.g. pre-op assessment – needs collaboration with Surgery
• CT evaluation of PAH and RVD in subjects with PH W.H.O.
Group 1 – collaboration with Radiology: ongoing
• Echocardiographic evaluation of RV function in PH subsets –
collaboration with cardiology, ongoing.
• PROSPECT Registry
