Results
Among a total of 374 patients included in our study, 269(71.9%) were male,25(6.7%) who underwent MIDCAB. As shown in Table 1, patients in the LIMA group were younger than the SVG group before propensity Score-Matched. There was no difference in the other data.
The comparison of blood flow parameters examined by TTFM between LIMA-LAD and SVG-LAD beforepropensity 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)( Table 2).
