A Case Report of Subacute Infective Endocarditis Presenting With Extreme Weight Loss, Aortic Regurgitation, and Splenic Infarct.

We present an insightful case of a middle-aged male who presented to the emergency department (ED) with complaints of excessive weight loss, accompanied by shortness of breath and vomiting. Consequently, this case explores many facets of the pathophysiology of infective endocarditis (IE), including but not limited to the most heavily implicated microorganisms, symptoms, predispositions, and disease outcomes. IE is a pathology of variable presentation with uniquely extensive diagnostic criteria, making it a fascinating topic of medical discussion.
