What Is Subacute Bacterial Endocarditis?
Disease name: SBE: Subacute Bacterial Endocarditis, subacute bacterial endocarditis, also known as subacute infective endocarditis. Caused by Streptococcus green. It most often invades the mitral and aortic valves, and is characterized by the formation of vegetation on the diseased valve, which is brittle, easy to break and fall, and the valve is easy to deform and perforate.

Subacute bacterial endocarditis disease name
- Disease name: SBE: Subacute Bacterial Endocarditis, subacute bacterial endocarditis, also called subacute infective endocarditis. Caused by Streptococcus green. It most often invades the mitral and aortic valves, and is characterized by the formation of vegetation on the diseased valve, which is brittle, easy to break and fall, and the valve is easy to deform and perforate.
Causes of subacute bacterial endocarditis
- 1. Pathogens invade the bloodstream: cause bacteremia, sepsis or sepsis and invade the endocardium;
- 2. Heart valve abnormalities: conducive to colonization and reproduction of pathogenic microorganisms;
- 3. Inhibition of defense mechanisms: For example, the causes of tumor patients using cytotoxic drugs and immunosuppressants in organ transplant patients include various bacterial fungi and coxella burnettii
Clinical symptoms of subacute bacterial endocarditis
- Subacute infective endocarditis: more common and important than acute
- (1) General manifestations: most cases have a slow onset, low fever, fatigue, and a few have an acute onset of chills, high fever, or embolism. Some patients have a history of oral surgery, respiratory infection, abortion, or delivery before onset.
- (2) Fever: Fever is most common when accompanied by systemic infection. Unexplained persistent fever lasts for more than a week. Irregular low fever is usually between and . It can also be intermittent fever or relaxation fever with fatigue and night sweats. Late clubbing fingers
- (3) Mental disorders: Patients may be accompanied by mild mental symptoms but rarely have serious mental disorders or delirium. If endocarditis is accompanied by subarachnoid hemorrhage or meningitis, aggression and mental disturbance and conscious disturbance may occur Signs of focal nervous system
- Almost all untreated acute patients die within 4 weeks, and the natural history of subacute patients is generally> 6 months. Among the poor prognostic factors, heart failure is the most serious. Except for those with endocarditis caused by resistant Gram-negative bacilli and fungi, most patients can be cured bacteriologically. However, the short-term and long-term mortality of this disease is still high.
Subacute bacterial endocarditis symptoms
- Slow onset, manifested as fever, irregular heat, fatigue, sweating, progressive anemia, weight loss, joint pain, etc., and later may have symptoms of organ embolism.
Subacute bacterial endocarditis
- In the original heart murmur, the nature and intensity of the murmur changed in a considerable number of cases during the course of the disease. Some cases have Euclidean nodules, but also Jenway's nodules. Corresponding signs of brain, spleen, kidney and other organ embolism can be seen in the later stage.

Western medicine treatment of subacute bacterial endocarditis
- In principle, penicillin is selected for the treatment of sufficient foot volume early and intravenous administration is highly recommended. (Same for streptomycin)
Prevention of subacute bacterial endocarditis
- Patients with heart valve disease or cardiovascular malformations and artificial valves should strengthen their physique, pay attention to hygiene, and clear the infected lesions in time. Antibiotics should be used prophylactically in dental and upper respiratory tract surgery or mechanical operations, surgery or procedures in the lower gastrointestinal tract, gallbladder, and urogenital tract, as well as other surgical operations involving infectivity. In dental and upper respiratory tract surgery and mechanical operations, penicillin G is generally administered intravenously at a rate of 1 to 1.2 million u half an hour before surgery and procaine penicillin is injected 800,000 u intramuscularly. Streptomycin 1 g / d is added if necessary , And then given for another 2 to 3 days. For gastrointestinal tract, urogenital system surgery or mechanical operation, the combined application of ampicillin and Qingda can be used before and after surgery.

- 1. Measures to prevent infective endocarditis in patients with susceptible factors during surgery or operation:
- 2, oral upper respiratory tract operations or surgery should be given antibiotics against Streptococcus grass green.
- 3, urogenital and digestive system surgery or operators should be directed against enterococcus medication.
