Results:
Before propensity Score-Matched, compared with the LIMA-LAD group, the
SVG-LAD group had a significantly higher mean graft flow volume
(37.85±23.28 vs 29.70±20.97ml/min, P=0.021),but a lower value of pulse
index (2.12±0.68 vs 2.65±1.01,P<0.001).There was no significant
difference between the two groups in terms of DF(P>0.05). After 1:2
propensity Score-Matched, there were 114 patients were included (SVG-LAD
38, LIMA-LAD 76), there was no difference in the baseline data between
the two groups. Compared with the LIMA-LAD group, the SVG-LAD group also
had a lower value of pulse index (2.07±0.63 vs 2.74±1.02,P<0.001),and
also a higher mean graft flow volume (37.27±24.31 vs
29.92±21.92ml/min),but there was no statistically difference(P=0.109).
There was no significant difference between the two groups in DF
(P>0.05). There was no difference among the two groups in patency
rate(P=0.405).
