Exercise testing Fluid loading
Clinical relevance for symptom assessment + + + +
Clinical relevance for differential diagnosis + + + +
主要优势 Respects the pathophysiology; comprehensive test, allowing for additional insights in pulmonary vascular disease (dynamic pulmonary vascular resistance); complementary with cardiopulmonary exercise testing Easy to perform, no specific setting; minimal risk of misinterpretation of pressures reading; better established cut-off defining abnormal increase in pulmonary arterial wedge pressure
Main limitations Requires a specific complex setting; expertise in conducting the test; pressure reading during exercise; range of normal response uncertain Unknown response in disease state; age dependency of response
