Results of the CT angiography examined before discharge in the two groups.
A total of 374 patients (313 patients in the LIMA-LAD group and 43 patients in the SVG-LAD group) were examined for coronary CT angiography before discharge. Table 5 lists the coronary CT angiographic results. The patency rate of the LIMA-LAD group was 98.72% (309/313), and that of the SVG-LAD group was 100%. There was no difference between the two groups in the patency rate.
