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 |
