Abstract

AIM: We aimed to investigate the effects of Empagliflozin on cardiac arrhythmias and heart rate variability in kidney transplant recipients (KTRs).

METHODS: Twenty-seven diabetic patients who underwent kidney transplantation between August 2020 and August 2023 were included. Patients with HbA1c >8% were received Empagliflozin treatment. A 24-hour Holter ECG monitoring was performed before and one year after beginning Empagliflozin. Holter ECGs were evaluated by a single cardiologist, comparing ventricular ectopic beats (VEB) and supraventricular ectopic beats (SEB) arrhythmias and heart rate variability parameters before and after one year of Empagliflozin treatment.

RESULTS: Twenty-seven patients completed the study, and the mean patient age was 56.1 ± 10 years. Fifteen of the patients (55.6%) were male. The mean duration since transplant before starting Empagliflozin was 62.8 ± 46.2 months. In follow-up, HbA1c decreased from 8.2% to 7.7%(P = .075), urine protein/creatinine ratio reduced from 0.437 ± 0.428 to 0.267 ± 0.146 gr/g (P = .056), and platelet count increased significantly (P = .004). After one year of treatment, the number of VEBs and SEBs in the patients decreased compared to pretreatment. They decreased from 173.5 ± 460.8 and 514.8 ± 265 beats before treatment to 125.1 ± 231.7 and 125.1 ± 231.7 beats after treatment, respectively, but did not reach statistical significance (P > .05). No significant changes were found in heart rate variability parameters (P >…
