Prospective Clinical Follow-Up Results of Infective Endocarditis.

Abstract

Objective: Infective endocarditis incidence has been rising in recent years, with high mortality. Risk factors such as underlying heart diseases, chronic diseases, healthcare-associated infections, advanced age, and intravenous (IV) drug use have gained importance in the incidence, the treatment approach, and the disease course. The aim of this study is to contribute to Türkiye's data on infective endocarditis epidemiology and risk factors.

Materials and methods: This study examined risk factors, diagnostic and treatment approaches, and prognosis of infective endocarditis cases at Pamukkale University Faculty of Medicine Hospital. It was carried out prospectively for 28 months.

Results: During this period, 67 endocarditis cases were detected in 65 patients. Among cardiac diseases, the rate of congenital heart diseases (41%), degenerative heart diseases (37%), and acute rheumatic fever (ARF) related valvular heart disease (31%) were found to be high. Hospitalization in the last six months (53.7%), history of cardiac surgery (41.8%), use of IV catheters (22.4%), hemodialysis (14.9%) and IV drug use (7.5%) were also determined. Staphylococci, streptococci, and enterococci were the primary agents. The most used empirical treatments were ampicillin, ampicillin-sulbactam, and gentamicin. Natural valve endocarditis was most determined. Surgical treatment was applied in 56.7% of endocarditis cases. Septic embolism and cardiac failure were the most common complications.

Conclusion: This study's findings regarding the epidemiology and prognosis of infective endocarditis pointed out that it is still a disease with a high mortality rate.
