Machine learning-based predictive model for pulmonary hypertension risk stratification in chronic kidney disease: development, internal validation and temporal external validation
Among chronic kidney disease (CKD) patients referred for right heart catheterization (RHC) due to clinical suspicion of pulmonary hypertension (PH), PH is a highly prevalent complication and contributes to increased cardiac mortality. This study aimed to develop and validate a machine learning (ML)-based predicti...
