Left Ventricular Diastolic Dysfunction Common in Non-Dialysis Chronic Kidney Disease

Researchers sought to determine predictors and prevalence of pulmonary hypertension, LVDD, and LV systolic dysfunction in patients with CKD that do not need dialysis.

A study found that the prevalence of left ventricular diastolic dysfunction (LVDD) in patients with chronic kidney disease (CKD) that do not require dialysis is 43.65%. These findings were published in Nefrologia.

This cross-sectional observational study was conducted at the Banaras Hindu University in India between 2020 and 2021. Patients (N=378) with stage 3b-5ND CKD according to the Kidney Disease Improving Global Outcomes 2012 guidelines were evaluated for cardiovascular health using transthoracic 2-dimensional (2D) and doppler echocardiography.

The patients were aged mean 51.56±13.39 years, 65.6% were men, and the most common CKD etiology was diabetic kidney disease (37.6%).

The prevalence of LVDD was 43.65%. In patients with LVDD 56.96% had grade 1, 27.88% had grade 2, and 15.16% had grade 3. Significant predictors of LVDD included hypertension (odds ratio [OR], 4.692; 95% CI, 2.464-8.933; P <.001) and duration of CKD (OR, 1.807; 95% CI, 1.072-3.047; P =.03).

The prevalence of left ventricular systolic dysfunction (LVSD) was 15.6%. In patients with LVSD left ventricular ejection fraction was 41% to 50% among 28.8%, 31% to 40% among 67.8%, and 30% or more among 3.4%. LVSD was associated with duration of CKD (OR, 2.731; 95% CI, 1.093-6.821; P =.03), urine protein concentration (OR, 1.725; 95% CI, 1.195-2.490; P =.004), estimated glomerular filtration rate (eGFR; OR, 0.828; 95% CI, 0.711-0.965; P =.02), and serum albumin concentration (OR, 0.124; 95% CI, 0.045-0.347; P <.001).

Severity of LVDD correlated with serum creatinine concentration (r, 0.388; P <.001), duration of CKD (r, 0.450; P <.001), serum intact parathyroid hormone levels (iPTH; r, 0.198; P =.01), serum uric acid concentration (r, 0.188; P =.02), eGFR (r, -0.353; P <.001), and serum vitamin D concentration (r, -0.194; P =.001). LVSD correlated with serum albumin concentration (r, -0.268; P =.04).

The prevalence of pulmonary hypertension (PH) was 12.2%. Among patients with PH 6.6% had comorbid LVDD. The significant predictors for PH were duration of CKD (OR, 3.838; 95% CI, 1.276-11.547; P =.02), hemoglobin (OR, 1.877; 95% CI, 1.169-3.012; P =.009), serum iPTH concentration (OR, 0.995; 95% CI, 0.991-1; P =.04), and serum vitamin D concentration (OR, 0.880; 95% CI, 0.827-0.936; P <.001).

This study does not evaluate type of PH and is not able to assess causal relationships due to its cross-sectional design.

“In our study the prevalence of PH is 12.2%, LV systolic dysfunction is 15.6% and LVDD is 43.65%,” the study authors wrote. “Prognostic implications and utility of these predictors requires prospective or randomized control studies for better validation.”
