Abstract: Objective  To investigate the clinical characteristics of children with mycoplasma pneumonia infection complicated by heart failure. Methods  Retrospective analysis was conducted on the clinical data of 53 children who were hospitalized at  Fujian Provincial Maternity and Children’s Hospital due to mycoplasma pneumonia infection complicated by heart failure between October 2012 and June 2018. A total of 111 concurrent children with mycoplasma pneumonia infection and no complications were selected as control group. General information and results of laboratory tests between two groups were compared. Results  Thirty cases(56.6%) of children with mycoplasma pneumonia infection complicated by heart failure were one year or younger. Fortyfour cases of children with mycoplasma pneumonia infection complicated by heart failure showed diminished heart sounds. Compared to the control group,  the group of children with mycoplasma pneumonia infection complicated by heart failure were exposed to higher proportions of dyspnea,  the underlying disease and coinfection of two or more noxaes,  higher white blood count,  Creactive protein and alactate dehydrogenase,  lower platelet count and hemoglobin with statistical significance. Conclusion  Mycoplasma pneumonia infection is more susceptible to being accompanied by heart failure if it presents in the infant period and is complicated with basic heart disease,  coinfection of two or more noxae,  high Creactive protein，alactate dehydrogenase and low hemoglobin levels.
