[Risk factors for infection after heart surgery]

A consecutive series of 84 patients operated by the same surgical team was studied in order to identify risk factors for post operative infection. Female sex and longer antibiotic prophylaxis were significantly associated with higher infection risk; the risk of dying of infection was more pronounced with infected men than with infected women. Diabetes, undernutrition, low albumin serum level in the first or in the fifth day post-operatively, asthma or pneumonia in the past did not correlate with infectious risk, as well as use of antibiotic before surgery or longer hospitalization before surgery.
