Surgical treatment for infectious endocarditis in China

Area of Science:

• Cardiology
• Cardiac Surgery
• Infectious Diseases

Background:

• Infectious endocarditis (IE) research is limited in developing countries.
• Previous studies on IE primarily originate from developed nations.
• Understanding IE-specific cardiac surgery mortality in China is crucial.

Purpose of the Study:

• To identify retrospective risk factors for hospital mortality in patients undergoing cardiac surgery for IE in China.
• To analyze factors associated with operative deaths in this patient population.
• To inform strategies for reducing mortality in IE cardiac surgery.

Main Methods:

• Retrospective analysis of 896 patients with IE who underwent cardiac surgery.
• Patients were divided into hospital mortality (n=48) and no hospital mortality (n=848) groups.
• Binary logistic regression was used to determine independent risk factors for mortality.

Main Results:

• The overall hospital mortality rate was 5.4% (48 deaths).
• Significant risk factors for hospital mortality included preoperative neurological complications, destructive annulus, preoperative mitral insufficiency, postoperative left ventricular ejection fraction, and paravalvular leak (P < .001).
• Several modifiable risk factors were identified.

Conclusions:

• Early diagnosis and surgical intervention are vital for improving outcomes.
• Advancements in surgical techniques and cardiac protection strategies can reduce hospital mortality.
• Identifying and managing specific risk factors can enhance survival rates for IE patients undergoing cardiac surgery.
