Risk Factors for Predictors of MACEs After RA-CABG

Study Overview
=================
Brief Summary
-----------------
As the secondary choice of artery grafts, radial artery is more and more used to achieve multiple arterial revascularization in CABG. Risk factors for predictors of major cardiovascular adverse events (MACE) after CABG using radial-artery grafts (RA-CABG), however, remain uncertain. This case-control study aims to identify the baseline predictors of MACE after RA-CABG. We will collect the baseline characteristics and perioperative data of patients underwent RA-CABG from Jan. 2009 to Dec. 2019 in our single center. By reviewing the latest follow-up records, we will examine the correlation between the baseline characteristics and clinical outcomes (MACEs), then identify the independent risk factors for predictors of MACEs after RA-CABG.
