Subacute Bacterial What Is

Subacute bacterial endocarditis (SBE) is a rare but serious infection of the lining of the heart, caused by bacteria that enter the bloodstream and settle in the heart. It is different from acute bacterial endocarditis, which is a rapidly progressing infection that typically occurs in people with heart valve problems or other underlying heart conditions. SBE typically develops over weeks or months and can affect people of all ages, including those without any known heart problems. The most common symptoms of SBE include fever, chills, fatigue, weakness, weight loss, night sweats, shortness of breath, and joint pain. Treatment for SBE usually involves long-term antibiotics and, in some cases, surgery to repair or replace damaged heart valves.
