About this study

This retrospective cohort study was intended to analyze the incidence and risk factors of perioperative severe cardiovascular events in patients with diastolic dysfunction.

Read the detailed description

The investigators retrospected patients underwent noncardiac surgery with pre-operative echocardiography and was diagnosed with diastolic dysfunction in 2015 in Peking University First Hospital. Patients' perioperative data were collected. Major adverse cardiovascular events(MACE), other complication incidence, and post-operative hospital stay were reviewed. propotional harzad ratio cox survival model was established. Risk and protective factors relative to MACE were analysed.
