Motivation: While cardiovascular magnetic resonance (CMR) is a well-established tool for assessing heart remodeling and predicting outcomes, its application in Chronic thromboembolic pulmonary hypertension (CTEPH) has received limited attention.
Goal(s): This study investigated whether biventricular remodeling derived form CMR could predict adverse clinical outcomes during the long-term follow-up of CTEPH patients.
Approach: Establish a CMR-only model and compare its predictive value with the model that combines clinical data and invasive RHC.
Results: CMR-derived biventricular remodeling have prognostic value in long-term follow-up CTEPH. Risk assessment based on CMR alone is at least as effective as that of clinic combined RHC.
Impact: These findings contribute to the optimization of early patient care and timely intervention. it's advisable to add CMR parameters in the management score. And performing noninvasive CMR alone is sufficient, as it also demonstrates excellent predictive efficacy.
