Example 1: A patient presents with fever, chills, and a new heart murmur. Blood cultures are positive for bacteria, and an echocardiogram reveals vegetations on the heart valves, confirming a diagnosis of acute infective endocarditis., A patient with a history of intravenous drug use develops persistent fever and fatigue.After further examination and testing, they are diagnosed with subacute endocarditis., A patient with a prosthetic heart valve develops signs and symptoms consistent with endocarditis.This requires prompt evaluation and treatment to prevent potential complications.
