Abstract:

Objective To evaluate the correlation between cardiac troponin (cTn) and D-dimer (D-D) levels and mortality in coronavirus disease 2019 (COVID-19) critical illness patients. Methods We searched related researches using COVID-19 and cTn as keyword in PubMed, Wanfang Journal Database, CNKI, VIP Chinese Scientific and Technological Periodical Database (VIP), etc., the period is from January 1, 2020 to December 31, 2021. Two reviewers independently conducted this work. We performed Meta-analysis using RevMan5.3 software, and the results were expressed as relative risk (RR) and its 95% confidence interval (CI). Results There were eligible15 literatures in the analysis, the Newcastle-Ottawa Quality Assessment Scale(NOS) scores were ≥6, and involving 7290 inpatients with COVID-19 critical illness, of which 1820 as the death group and 5470 as the survival group. Meta-analysis results showed that both elevated cTn level (RR=3.13, 95%CI=2.13-4.62, Z=5.76, P<0.01) and up-regulated D-D level (RR=1.69, 95%CI=1.27-2.26, Z=3.60, P=0.0003) of COVID-19 patients had obviously higher mortality. The results of gender subgroup analysis indicated that the mortality of COVID-19 male patients was more prevalent (P<0.01). Conclusion For COVID-19 critical illness patients, both elevated cTn level and up-regulation D-D level are more likely to rise mortality.
