| 目的 观察左、右优势型冠状动脉（冠脉）粥样硬化斑块负荷差异。方法 纳入冠脉呈左优势型（左冠优势组）及右优势型（右冠优势组）的患者各63例，比较组间节段受累评分（SIS），分析其冠脉粥样硬化负荷差异。结果 2组冠脉斑块负荷差异无统计学意义（χ2=1.026，P=0.311）。左冠优势组低危负荷斑块多于右冠优势组（χ2=4.493，P=0.034）。2组SIS差异均无统计学意义（P均>0.05）；而组间整体及男性患者右冠节段SIS差异存在统计学意义（P均<0.05）。结论 右优势型冠脉出现高危负荷粥样硬化斑块的风险高于左优势型；且左、右优势型冠脉右冠节段SIS差异显著，特别是在男性中。 |

| Objective To observe the difference of atherosclerotic plaque burden between left and right coronary dominance. Methods Sixty-three patients with left coronary dominance (left coronary dominance group) and 63 patients with right coronary dominance (right coronary dominance group) were enrolled. Segment involvement score (SIS) was compared between groups, and the difference of coronary atherosclerotic plaque burden was analyzed. Results There was no significant difference of coronary atherosclerotic plaque burden between groups (χ2=1.026, P=0.311). The low-risk load plaques in left coronary dominance group were more than those in right coronary dominance group (χ2=4.493, P=0.034). There was no significant difference of SIS between 2 groups (all P>0.05), while there was significant difference of SIS of the right coronary segment in all patients, especially in male patients between 2 groups (both P<0.05). Conclusion The incidence of high-risk load of atherosclerotic plaque burden in right coronary dominance was higher than that in left coronary dominance. SIS of right coronary segment was significantly different between left and right coronary dominance, especially in males. |
