-CoVD
-Connective tissue dis
-Portal htn
-HIV infection
-Congenital HD
-Other(gly storage dis, Gaucher dis, hereditary hemorrhagic telangiectasia) - Asso w sig venous/capillary involve
-Pul veno-occlusive dis & Pul capillary
hemangiomatosis
-Persistent Pul Htn Newborn(PPHN)
7
Q
Group 2. Pulmonary Arterial Hypertension (PAH) Due to Left Heart Disease?(2)

Group 3. Pulmonary Hypertension Due to Lung Disease Associated With Hypoxemia?(5)
A
- COPD
- Interstitial lung dis
- Sleep-disorder breathing
- Alveolar hypoventilation disorder
- Chronic exposure to high altitude
9
Q
Group 4. Pulmonary Hypertension Due to Chronic Thrombotic and/or Embolic Disease (CTEPH)? (2)
A
- Thromboembo obs prox/distal pul art
2. Pul embo(tumor, parasite, foreign material)
10
Q

- Dyspnea(60%)
- Fatigue(19%)
- Near syncope/syncope(13%)
- Chest pain(7%)
- Palpitation(5%)
- Leg edema(3%)
- Hoarse voice(ortner syn)
- Hemoptysis(rare)
12
Q
Sign PHTN? (5)
A
- No signs
- Congest Neck vein: Inc JVP
- Cyanosis
- Precordial examination
- pul art dilatation
- rt ventricular hypertrophy - Auscultation:
- Closely split second sound w accentuated pul component
- Pul systolic ejection click.
- Ejection sys murmur/early dias (Graham-Steele) murmur is heard
13
Q
Inv PHTN?
A
- Electrocardiogram
- CXR & nCT chest
- Echocardiography
- Cardiac MRI
- Cardiac catheterization
- Lung biopsy
- Pul fx test
- Screen BMPR2 gene mutation
- Polysomnography
14
Q
Complication PHTN?(4)
A
- Rt HF
- Pul art dissection & rupture, massive hemoptysis, lt main compress syn
- Hemoptysis 2ry to bronchial art source, hypoxic vasoconstriction leads to collateralization & proliferation bronchial art
- Supraventricular, less commonly ventricular arrhythmias
15
Q
Goals of Therapy?(4)
A
- Alleviate symptoms, improve exercise capacity & quality of life
- Improve cardiopulmonary hemodynamic & prevent rt hf
- Delay clinical worsening
- Reduce morbidity & mortality
