Pulmonary hypertension is highly prevalent in patients with chronic kidney disease, particularly those on hemodialysis, suggesting a need for routine echocardiographic screening in this population.
May support echocardiographic screening in CKD; leaves open whether detection improves outcomes in prospective studies.
Background: (2D) color Doppler echocardiography. Materials and Methods: This is an observational cross-sectional study. A total of 100 CKD patients on hemodialysis or conservative management were enrolled in the study. Following the collection of demographic data, and routine/specific investigations, these patients were assessed for PH using 2D color Doppler echocardiography. Results: ventricular and left atrial/LV chambers, and valvular hypertrophy were other echocardiography findings recorded in these patients. Low hemoglobin levels, high urea/creatinine levels, and duration of hemodialysis in CKD patients were found to be significantly associated with the presence of PH. Conclusion: The majority of CKD patients have PH at various stages of disease-causing unexplained dyspnea in these patients. PH is common in end-stage CKD as compared to patients with a less severe stage of CKD. Hence, CKD patients should be evaluated for PH, especially in the presence of intractable dyspnea.

Gaur et al. (2023) conducted a cross-sectional in Chronic Kidney Disease (n=100). Hemodialysis vs. Conservative management was evaluated on Presence of pulmonary hypertension (RVSP ≥35 mmHg) (p=0.03). Pulmonary hypertension was present in 47% of chronic kidney disease patients and was significantly more common in those on hemodialysis compared to conservative management (56% vs 38%, p=0.03).
