Abstract
IntroductionSex-differences in high sensitivity troponin (hs-Tn) concentrations are well established. There is, however, limited data to guide interpretation of hs-Tn in transgender patients, particularly those receiving gender-affirming hormone therapy. Our purpose was to evaluate troponin testing in transgender patients. MethodsTransgender adults attending a routine clinic visit provided demographic data, medical history, and venous blood samples. Patients with congestive heart failure or chronic kidney disease were excluded. hs-Tn was measured using the Architect Stat High Sensitivity Troponin-I (Abbott), Access 2 hsTnI (Beckman Coulter), and Elecsys Troponin T Gen 5 STAT (Roche) assays. hs-Tn below the limit of detection (LOD) is reported as the lower limit of detection (LLOD) ResultsOf 63 subjects, 76 % were transgender women. We found no significant difference in median hs-Tn concentrations or proportions of hs-Tn > LOD. ConclusionIn this cohort of stable transgender patients without CHF or CKD, we did not observe differences in hs-Tn concentrations between transgender women and transgender men. Meaningful conclusions are limited owing to inadequate sample size and population differences. Further research on hs-troponin concentrations in this underrepresented, vulnerable population is needed.
