Introduction: Cardiovascular diseases are associated with increased morbidity and mortality among CKD (chronic kidney disease) population. Recent studies have found increasing prevalence of PH (pulmonary hypertension) in CKD population. Present study was done to determine prevalence and predictors of LV (left ventricular) systolic dysfunction, LVDD (left ventricular diastolic dysfunction) and PH in CKD 3b-5ND (non-dialysis) patients. Methods: A cross sectional observational study was done from Jan/2020 to April/2021. CKD 3b-5ND patients aged ≥15 yrs were included. Transthoracic 2D (2 dimensional) echocardiography was done in all patients. PH was defined as if PASP (pulmonary artery systolic pressure) value above 35 mm Hg, LV systolic dysfunction was defined as LVEF (left ventricular ejection fraction) ≤ 50% and LVDD as E/e′ ratio >14 respectively. Multivariate logistic regression model was done to determine the predictors. Results: A total of 378 patients were included in the study with 103 in stage 3b, 175 in stage 4 and 100 patients in stage 5ND. Prevalence of PH was 12.2%, LV systolic dysfunction was 15.6% and LVDD was 43.65%. Predictors of PH were duration of CKD, haemoglobin, serum 25-OH vitamin D, serum iPTH (intact parathyroid hormone) and serum albumin. Predictors of LVDD were duration of CKD and presence of arterial hypertension. Predictors of LV systolic dysfunction were eGFR (estimated glomerular filtration rate), duration of CKD, serum albumin and urine protein. Conclusion: In our study of 378 CKD 3b-5ND patients prevalence of PH was 12.2%, LV systolic dysfunction was 15.6% and LVDD was 43.65%. © 2022 Sociedad Española de Nefrología
