2.2 | Follow-up
The follow-up was primarily carried out by telephone interview one year after CAGB surgery. If follow-up information could not be obtained, we contacted civil registration offices and requested information about current address or date of death. The postoperative outcome was assessed using the MACCE (Major Adverse Cardiac and Cerebrovascular Events) criteria established for patients with CHD: 1. No event 2. Myocardial infarction 3. Low cardiac output syndrome 4. Tachycardia (VT) 5. Angina pectoris 6. Renewed revascularization surgery 7. Cardiac decompensation 8. Peripheral circulatory failure 9. Stroke / Transient ischemic attack (TIA) / Prolonged reversible ischemic neurological deficit (PRIND) 10. Cardiac death 11. Stroke death 12. Not cardiac death.
