Study Notes
Vascular Pulmonary Disorders
- Vascular diseases involve pulmonary arteries and veins, leading to obstruction (embolism) or disruption of alveolar-capillary membrane (edema).
- These conditions can result in pulmonary hypertension and right heart failure.
Epidemiology
- Pulmonary embolism has an incidence rate of 310 cases per 1,000,000 persons in Australia.
- In the USA, pulmonary hypertension affects 2-5 million individuals annually.
Disease Classification
- Classification of respiratory diseases is guided by ATS/ERS standards established in 2005.
Diagnostic Techniques
- Computed Tomography Scan: Provides detailed imaging of pulmonary structures.
- Ventilation/Perfusion Scan: Assesses airflow and blood flow in the lungs.
- Echocardiography: Evaluates heart function and structure.
- Right Heart Catheterization: Measures pressures in the heart and lungs, used for definitive diagnosis of pulmonary hypertension.
- Chest X-ray: Offers a basic view of lung conditions.
- Pulmonary Angiogram: Visualizes blood vessels in the lungs to detect blockages.
Pulmonary Hypertension
- Definitive diagnosis requires right heart catheterization showing mean pulmonary artery pressure (PA) >25 mm Hg at rest or ≥30 mm Hg during exercise.
- Mean pulmonary capillary wedge pressure (PCWP) or left ventricular end-diastolic pressure (LVEDP) may also be assessed for comprehensive diagnosis.
