Background: The incidence of chronic kidney disease (CKD) is increasing globally and is associated with significant morbidity and mortality related to the cardiovascular system. There is limited data on pulmonary hypertension (PH) in CKD patients, especially from developing and underdeveloped countries. PH leads to hypoxia which is a significant cause of dyspnea in CKD patients with or without pulmonary edema. Hence, we planned this study to assess the PH in CKD patients using two-dimensional (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: PH was found in 47% of patients with CKD. Left ventricular (LV) hypertrophy, systolic and diastolic dysfunction, dilated right atrium/right 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.
