Abstract

Objectives: There are arguments regarding the relationship between the level of cardiac troponin I (cTnI) and presence of cardiac diseases in end-stage renal disease (ESRD) patients. This study aimed to determine the relationship between positivity of cTnI and cause of admission and patients’ outcome in ESRD patients. Methods: In this cross-sectional study, all ESRD patients who had checked cTnI and admitted to two university hospitals in Isfahan, Iran were enrolled. The patients’ demographic characteristics, cause of admission, and outcome were correlated with cTnI positivity. Results: Out of a total of 348 ESRD patients, 100 subjects had positive cTnI. There was a positive correlation between age and admission in Al-Zahra hospital with positive cTnI. In contrast, vascular access complication and hypertension had a negative correlation with positivity of cTnI. The results of multiple logistic regression analysis showed that factors including age (OR: 1.04; 95% CI: 1.01-1.07; P: 0.004) and infections (OR: 3.1; 95% CI: 1.3-7.3; P: 0.009) were associated with increased risk of in-hospital mortality. In contrary, exit site infection (OR: 0.11; 95% CI: 0.01-0.8; P: 0.03) and hypertension (OR = 0.32; 95% CI: 0.14-0.77; P = 0.01) were associated with decreased risk of mortality. Although cTnI positivity correlated with patients’ in-hospital mortality (OR = 2.038). Conclusions: Although positive cTnI had a borderline association with in-hospital mortality in ESRD patients, further multicenter studies with larger sample size are required to confirm the results. © 2021, Author(s.
