Background: D-dimer and LDH are crucial biomarkers, particularly in view of the fact that they have been strongly linked to COVID-19 infection and have been linked to worse consequences in people who have severe viral infections.

Objectives: To determine how D-dimer and LDH correlated with clinical effects in COVID-19 patients who were hospitalised and how they forecasted the severity of COVID-19 patients.

Material and Methods: This was cross-sectional research conducted relatively early in the second wave of the pandemic. A total of 110 patients diagnosed with COVID-19 and admitted to the ICU from January 2021 to June 2021, were included in the study. The clinical outcome was evaluated in terms of discharge and death among patients requiring various forms of assisted ventilation.

Results: The average age of patients was 53.16 years (± 18.47 years). 35.5% of the patients were with comorbidities of which diabetes, hypertension, and COPD were around 80%. D-dimer was deranged in 2.7% of the subjects and LDH was deranged in 60% of the study subjects at the time of admission. Coming on to the outcome, all patients were put on assisted ventilation with 71.8% on NIV, 20% on HFNO, 1% on CPAP, and 7.2% on MV. During their hospital stays, 6 (5.45%) patients died and the remaining patients were discharged. A higher D-dimer value (> 1.5 μg/ml) during the hospital stay was found to be statistically significant with assisted ventilation and deaths of the admitted study subjects.

Conclusion: In our investigation, the biomarker D-dimer value was more associated than LDH with mortality in patients with COVID-19 infection.
