Analysis of Incidence and Risk Factors of Severe Cardiovascular Events in Patients With Diastolic Dysfunction

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

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.

Inclusion Criteria:

• 18 years old or older, with echocardiographic diagnosis of left ventricular diastolic dysfunction (while ejection fraction was > = 50%) conducted by cardiologist within 90 days before surgery.

Exclusion Criteria:

• congenital heart disease, moderate to severe valvular disease (stenosis or insufficiency), atrial fibrillation / atrial flutter, pericarditis, unsatisfied cardiac ultrasound image, ejection fraction < 50%, ASA greater than 4, or Echocardiography is missing or incomplete.
