ExRHC remains the gold standard for confirming ExPH, defined by a mPAP\/CO slope &gt;3\u2009mmHg\/L\/min with normal pulmonary arterial wedge pressure (PAWP) and elevated pulmonary vascular resistance (PVR) during exercise. Nevertheless, due to its invasive nature and limited availability, ExRHC is not suitable for first\u2010line screening. For early evaluation, non\u2010invasive tests such as CPET and ESE may be preferred, as they provide a broader, safer and more accessible functional assessment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Stress testing is a valuable tool in the functional assessment of CTEPD without PH and should be systematically integrated into post\u2010PE screening protocols. Early use of CPET and ESE allows detection of subclinical pulmonary vascular dysfunction, guiding appropriate referral and treatment, while exercise RHC should be reserved for selected cases with inconclusive findings or complex physiology.<\/jats:p>\n
