Context. Diabetes mellitus is a well known risk factor for COVID-19 patients. However, There is limited data to investigate the association between prediabetes and COVID-19. Objective. We aimed to evaluate the effect of prediabetes and mechanical ventilation on the course of COVID-19 and determine whether patients who recover from COVID-19 infection show changes in cardiac function and laboratory findings during follow-up. Patients and Methods. This study included 87 adult patients who were diagnosed with COVID-19 according to the WHO definition and were admitted for inpatient treatment between April 2021 and August 2021. They were classified into 3 groups, normoglycemia (n=40), prediabetes (n=25), and diabetes (n=22), and then divided into groups according to need for mechanical ventilation. Statistical analyses were performed to compare laboratory, echocardiographic findings and COVID-19 outcomes among the groups. Results. The need of mechanical ventilation was significantly higher in both diabetes and prediabetes groups than the normoglycemic group. Patients with diabetes and prediabetes had significantly higher LV E/Em (p=0.003, p=0.045) and RV MPI (p=0.032, p=0.021) and significantly shorter PAT (p=0.001, p=0.036) and significantly longer RV IVRT (p=0.021, p=0.017), respectively, compared to the normoglycemia group. Patients who required mechanical ventilation had significantly higher CRP (p=0.043), troponin (p<0.001), ferritin (p<0.001), HBA1C (P<0.001), glucose (p=0.019), monocytes (p<0.001), and monocytes-HDL ratio (MHR) (p<0.001) and significantly lower levels of HDL-C (p<0.001). Glucose, HDL-C, troponin, MPV, NLR, PLR level and RV and E/Em were found independently associated with the RVMPI Conclusion. Prediabetes was associated with more impaired LV and RV diastolic functions compared to normoglycemic patients, comparable to those seen in diabetes. Our observations suggest that prediabetes should be considered as diabetes in the risk stratification of patients with COVID-19.
