Objective To investigate the distribution and drug resistance of bloodstream infection pathogens in cardiovascular patients in TEDA International Cardiovascular Hospital, and to provide evidence for rational use of antibiotics.Methods The distribution and drug resistance of bloodstream infection pathogens in TEDA International Cardiovascular Hospital were retrospectively analyzed from January 2012 to December 2020.Results Total 234 strains of bloodstream infection pathogens were isolated. Gram-negative bacteria (133 strains) accounted for 56.8%, and main of them were Escherichia coli, Klebsiella pneumonia, and Enterobacter cloacae. Gram-positive bacteria were 95 strains (40.6%), and main of them were coagulase negative Staphylococcus, Viridans streptococcus, and Staphylococcus aureus. Fungi were 6 strains, accounting for 2.6%. Escherichia coli, Klebsiella pneumonia, and Enterobacter cloacae were highly sensitive to carbapenems and amikacin. Among Staphylococcus, the detection rate of methicillin resistant coagulase negative Staphylococcus was higher than that of Staphylococcus aureus. No Gram-positive bacteria was resistant to linezolid, vancomycin, and teicopalnin.Conclusions Gram-negative bacteria are the main pathogens of bloodstream infection in cardiovascular patients in TEDA International Cardiovascular Hospital. It is necessary to strengthen surveillance of drug resistance of pathogens in bloodstream infection, in order to provide evidence for clinical doctors to use drugs empirically.
