The symptoms of bacterial endocarditis include two main parts: systemic symptoms as well as cardiac symptoms. In terms of systemic symptoms, patients can present with non-specific bacterial infection symptoms such as fever, generalized weakness and chills. If the patient has a combination of other organ and tissue infections in addition to endocardial infection, localized redness, swelling, heat, pain and hypofunctional symptoms at the corresponding infected location may occur. Local cardiac symptoms of endocarditis include precordial pain, chest tightness, arrhythmias, and decreased cardiac function such as decreased activity tolerance. If endocarditis affects the valves of the heart, abnormal blood flow such as valve stenosis and regurgitation may occur. Treatment of bacterial endocarditis generally requires anti-infective therapy with sensitive antibiotics under medical supervision, as well as maintenance of the patient’s general vital signs.
