The comparison of blood flow parameters examined by TTFM between LIMA-LAD and SVG-LAD after propensity Score-Matched
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.
After propensity Score-Matched, 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)( Table 3).
