(205) ASSOCIATION OF TESTOSTERONE REPLACEMENT THERAPY WITH ATRIAL FIBRILLATION AND ACUTE KIDNEY INJURY

Abstract Introduction Secondary analyses of the Testosterone Replacement Therapy for Assessment of Long-Term Vascular Events and Efficacy Response in Hypogonadal Men (TRAVERSE) trial revealed significantly higher rates of new-onset atrial fibrillation (AF) and acute kidney injury (AKI) in the TRT cohort. Objective To validate the secondary findings of the TRAVERSE trial. Methods We utilized the TriNetX Research Network to identify a cohort of men ages 45-80 years old who met similar inclusion criteria to the TRAVERSE trial. We compared hypogonadal men (testosterone 100-300 ng/dL) who had a prescription for topical testosterone therapy and men who did not. Propensity score matching was used to match patient populations. Kaplan Meier survival analysis was used to determine the relative risk of new-onset AF and AKI within 3 years. Results There were 2,134 men included in each cohort after propensity score matching. There was no significant difference in age or race/ethnicity between cohorts. Men on TRT had significantly lower T at the time of diagnosis compared to men not prescribed TRT (207 ± 66 ng/dl vs 246 ± 140 ng/dl, p < 0.001). Kaplan–Meier survival analysis showed a significantly increased risk AKI among men on TRT (RR 1.53, 95% CI 1.07-2.18). However, TRT was not associated with a significantly increased risk of new-onset AF (RR 1.48, 95% CI 0.93-2.37). Conclusions Similar to the TRAVERSE trial, our study demonstrated an increased risk of AKI among men on TRT, but did not find an increased risk of AF. Further studies are required to validate these findings. Disclosure Any of the authors act as a consultant, employee or shareholder of an industry for: Posterity Health.
