Abstract    Cardiac dysfunction is one of the most common complications of surgical patients during perioperative period，which lead to higher mortality rate，longer duration of hospitalization and more medical expenses. Thus，it is very important for early identification of high-risk patients，early intervention and early treatment. However，the risk factors of cardiac dysfunction during perioperative period is very complex，such as inappropriate fluid therapy，arrhythmia，hypertension，cardiovascular events，anesthesia，operation stress，etc. The treatment of cardiac dysfunction during perioperative period should follow the comments of multidisciplinary staff from surgery，cardiology and critically care，which should include the cardiovascular risk assessment. In addition，the patient's fluid and anti-arrhythmic therapy，cardiovascular event handling，operation，anesthesia and haemostatic scheme should be provided individually. Thus，the treatment can be optimized and improve security, reduce complications and improve the prognosis of patients.
