Abstract

Background/Objective: The aim of the present preliminary study was to assess the demographic, clinical, paraclinical, microbiological, echocardiographic, and therapeutic profile as well as in-hospital outcome of patients with infective endocarditis at a referral center for various infectious diseases in Iran.
Methods: Required demographic, clinical, plausible complications and paraclinical data were collected from patients’ medical charts. Echocardiographic findings were obtained by performing transthoracic and/or transesophageal echocardiography as clinically indicated. In addition, details of management modalities and in-hospital outcome of patients were recorded.
Results: During a 3-year period, 55 patients with definite or possible diagnosis of Infective endocarditis were admitted to the ward. Twenty one (38.2%) patients were injection drug users. Staphylococcus aureus and S. epidermidis were the most commonly isolated microorganisms. Management modalities of Infective endocarditis included antimicrobial therapy alone (48 cases) and the combination of antimicrobial therapy and surgery (7 cases).
Conclusion: The rate of negative blood culture in our cohort is high. S. aureus and S. epidermidis were the most commonly isolated microorganisms from positive blood cultures. Congestive heart failure was the most frequent infective endocarditis complication as well as indication for surgery. In-hospital mortality rate of patients was unexpectedly low.
