Incidence of Postoperative Major Adverse Cardiac Events in the Patients Underwent Carotid Endarterectomy: A Single Center Retrospective Study

The investigator plan to retrospectively investigate 175 carotid endarterectomy patients in Siriraj hospital to find the incidences of major adverse cardiac events, including

• Myocardial infarction is defined as rising of cardiac bio-markers in the setting of myocardial ischemia (Relevant anginal symptoms, ECG changes or Imaging e.g. Echocardiography)2,10
• Significant arrhythmia is defined as symptomatic or causing hemodynamic changes without other explainable causes.
• Heart failure is defined according to Modified Framingham criteria3
• Cardiac death is defined as mortality in association and as a direct result from myocardial infarction, arrhythmia or heart failure

if possible, the investigators will try to find the associate or risk factors for those events.
