| Objective We performed a single-centre retrospective observational study investigating the association between troponin positivity in patients hospitalised with COVID-19 and increased mortality in the short term. Methods All adults admitted with swab-proven RT-PCR COVID-19 to Homerton University Hospital (HUH) from 04.02.20 to 30.04.20 were eligible for inclusion. We retrospectively analysed demographic and biochemical data collected from the physical and electronic patient records according to the primary outcome of death at 28 days during hospital admission. Troponin positivity was defined above the upper limit of normal according to our local laboratory assay (>15.5ng/l for females, >34 ng/l for males). Univariate and multivariate logistical regression analyses were performed to evaluate the link between troponin positivity and death. Results Mean length of stay for all 402 hospitalised COVID-19 patients at HUH was 9.1 days (SD 12.0). Mean age was 65.3 years for men compared to 63.8 years for women. A chi-squared test showed that survival of COVID-19 patients was significantly higher in those with a negative troponin (p = 3.23 ×10−10) compared to those with a positive troponin. In the multivariate logistical regression, lung disease, age, troponin positivity and CPAP were all significantly associated with death, with an AUC of 0.8872, sensitivity of 0.9004 and specificity of 0.6292 for the model. Within this model, troponin positivity was independently associated with short term mortality (OR 3.23, 95% CI 1.53-7.16, p=0.00278). | |
