Classification of Pulmonary Hypertension in CKD
Cardiovascular disease continues to be the leading cause of morbidity and mortality across all stages of chronic kidney disease (CKD), with heart failure being highly prevalent in this population. Pulmonary hypertension (PH), defined as the presence of mean pulmonary artery pressure ≥ 25 mm Hg at rest obtained using right heart catheterization (RHC), contributes to the higher heart failure burden in CKD.1 Previous studies noted that PH is prevalent among 20% to 25% of patients with various stages of CKD.
