E/e' Ratio and Diastolic Function Between Deep Vein Catheterization and Internal Fistula Treatment in Patients with Chronic Kidney Disease

Objective: To examine the relationship between diastolic function and the ratio of early diastolic mitral inflow to early diastolic mitral annular velocity (E/e') in patients with chronic renal disease who had deep vein catheterization and internal fistula.

Methods: The clinical data of 50 uremia patients treated at The Affiliated Dongyang Hospital of Wenzhou Medical University from January 2020 to January 2022 were retrospectively analyzed. To assess the differences in E/e' ratio and patients' diastolic function between the two groups, they were split into two teams according to the various therapy modalities: the internal fistula team (n = 42) and the deep vein catheterization team (n = 8).

Results: After treatment, the left ventricular end-diastolic diameter (LVd), E peak, a peak and E/A value, the volume and area of four chambers of the left ventricle (LV), the volume and area of two chambers of LV in both groups were significantly lower than those before treatment (P < .001). After treatment, the LVd left ventricular end-systolic diameter (LVs), the four-chamber volume of LV, and the two-chamber volume and area of LV in patients with internal fistula were significantly lower than those in patients with deep vein catheterization (P < .001). After treatment, E peak, A peak and E/A value, e' interventricular septum, E/e' value of interventricular septum, e' lateral wall, and E of lateral wall in patients with internal fistula group.

Conclusion: Both deep vein catheterization and internal fistula treatment can improve the diastolic function and reduce the pulmonary pressure of uremic patients to a certain extent, but internal fistula treatment is better than deep vein catheterization in reducing LVd, LVs, LV four-chamber volume, LV two-chamber volume and area, and the effects of both in improving the E/e ratio of patients are not obvious.
