A retrospective analysis of high sensitivity cardiac troponin-T ranges in non-myocardial infarction emergency department visits
Introduction Current evidence suggests that high sensitivity cardiac troponin-T (hs-cTnT) values differ based on sex, race, age, and kidney function. However, most studies examining the relationship of hs-cTnT and these individual factors are in healthy participants, leading to difficulty in interpr...

Zusammenfassung: | Introduction Current evidence suggests that high sensitivity cardiac troponin-T (hs-cTnT) values differ based on sex, race, age, and kidney function. However, most studies examining the relationship of hs-cTnT and these individual factors are in healthy participants, leading to difficulty in interpreting hs-cTnT values in the Emergency Department (ED) setting. We seek to examine the relationship between hs-cTnT values and sex, race, age, and kidney function in a contemporary, urban academic setting. Methods ED visits from June 2018 through April 2019 with at least 1 hs-cTnT and no diagnosis of acute myocardial infarction (AMI) at an academic medical center in the south side of Chicago were retrospectively analyzed. Median hs-cTnT values were stratified by sex (male or female), race (African American or Caucasian), age, estimated glomerular filtration rate (eGFR), and stage of chronic kidney disease. Results
9679 encounters, representing 7989 distinct patients, were included for analysis (age 58 +/- 18 years, 59% female, 85% black). Males had significantly higher median hs-cTnT values than females (16 [8-34] vs. 9 [6-22] ng/L, p < 0.001), African Americans had a significantly lower median value than Caucasians (10 [6-24] vs. 15 [6-29] ng/L, p < 0.001), and those with atrial fibrillation (27 [16-48] vs. 9 [6-19] ng/L, p < 0.001) and heart failure (28 [14-48] vs. 8 [6-15] ng/L, p < 0.001) had higher median values than those without. Median hs-cTnT values increased significantly with increased age and decreased eGFR. All relationships continued to be significant even after multivariable regression of sex, age, race, eGFR, presence of atrial fibrillation, and presence of heart failure (p < 0.01). Conclusions Analysis of hs-cTnT in non-AMI patients during ED encounters showed that males have higher values than females, African Americans have lower values than Caucasians, those with atrial fibrillation and heart failure have higher values than those without, and that older age and lower eGFR were associated with higher median values. |
