Abstract

Background: Infective endocarditis (IE) is characterised by a concentration of infection inside the heart; it is caused by a bacterial or fungal infection of the endocardial surface of the heart; and it is linked with substantial morbidity and death.The aim of this research was to assess serum ferritin as an admission predictor of in-hospital prognosis in subjects with IE. Methods: This case control researchincluded60subjects diagnosed with IEon the basis of the modified duke's criteria.Subjects were allocated equally into two groups: group I: IE subjects who were further subdivided into two groups based on presence or absence of major adverse cardiovascular events   (subgroup A: 19 patients who showed IE complications or major adverse cardiac events during hospitalization and subgroup B: 11 patients who showed a smooth course during hospitalization without major adverse cardiac events or IE complications) and IE subjects as well as age and sex matched 30 healthy subjects. Results: serum ferritin level were significantly increased in group I than group II (P value<0.05). Serum ferritin level was significantly increased in subgroup A than subgroup B (P value<0.001). serum ferritin can significantly predict bad outcome (P value<0.001) with AUC of 0.964 (95% CI: 0.881 – 0.995). At cut off >1200, serum ferritin can significantly predict bad outcome with 94.44% sensitivity, 92.86% specificity, 85% PPV and 97.5% NPV. Conclusions: Serum ferritin was significantly increased in IE subjects who experiencedproblems on admission as compared to IE subjects who didn’t.
