Background: This study aims to reveal whether the Lymphocyte-C-reactive protein ratio (LCR), a systemic inflammatory marker, predicts disease progression in COVID-19 patients with myocardial injury. Methods: A total of 172 patients,18 years and older, hospitalized due to COVID 19 between April 2020 and May 2020 in our hospital were included retrospectively. Hg, leukocyte, lymphocyte, neutrophil, thrombocyte, AST, ALT, creatinine, LDH, albumin, ferritin, triglyceride, procalcitonin, C-reactive protein, fibrinogen, D-dimer, troponin, LCR values of the patients were recorded. LRC ratios were amplified as x100. Patients were divided into two groups as with and without myocardial injury. IBM SPSS Statistics 21.0 program was used for statistical analysis. Statistically, p <0.05 was considered significant. Results: Study patients were divided into two groups as with and without myocardial injury. The patients' mean age was 68.56 ± 13.43 years, 58.46 ± 16.67 years, respectively (p = 0.002). There was no difference between the groups in terms of the clinical severity of the disease, the severity of lung involvement on computed tomography, coronary artery disease, diabetes mellitus, chronic obstructive pulmonary disease, those with lymphocyte, CRP, LCR ratio, Ferritin, D-Dimer, and fibrinogen (all p> 0.05). Hypertension (HT), chronic renal failure (CRF) were more common in the group with myocardial injury (p <0.01, p <0.01). Procalcitonin and creatine levels were significantly higher in the group with myocardial injury (p = 0.002, p <0.001). When we analyzed the correlation analysis of parameters associated with myocardial injury with troponin, it showed a good correlation with CRF (r = 484, p <0.001), moderate with procalcitonin (r = 274, p <0.001, and weak correlation with age and HT (r = 484, p <0.001) = 180, p = 018) (r = 159, p = 037),respectively. DM and D-dimer did not correlate (r = 055, p = 472) (r = 072 p = 345).In the multivariate regression analysis, only CRF (Odds ratio (OD): 11.062 (95% confidence interval (CI): 1.866-65.580)) and reference procalcitonin levels (OR: 1.183, 95% CI: 1.014-1.379) predicted myocardial injury. Conclusion: Our study found that LRC did not predict disease progression in Covid-19 patients with myocardial injury.
