目的 分析冠状动脉Gensini评分 与左心功能间关系。方法 选择60例冠心 病患者为研究对象，均接受64排螺旋CT 冠状动脉造影检查，观察冠状动脉病变情 况，并分析Gensini评分与左心功能指标 的关系。结果 左冠状动脉前降支狭窄的 比例最高，其次为右冠和旋支。冠状动脉 Gensini评分0-165分，平均(22.6±4.7) 分。随冠状动脉Gensini评分升高，LVEF 逐渐降低，LVEDV及LVESV逐渐升高，组间 比较差异具有统计学意义(P＜0.01)。经 Spearman相关分析，冠状动脉Gensini评 分与LVEDV及LVESV呈显著正相关，与LVEF 呈显著负相关(P＜0.01)。结论 64排螺旋 CT不仅能够显示冠状动脉狭窄的程度，而 且得出冠状动脉Gensini评分与LVEDV及 LVESV呈显著正相关、与LVEF呈显著负相 关的评价结果。

Objective To analyze the relationship between the Gensini score of coronary artery and left ventricular function. Methods 60 patients with coronary heart disease as the research object, all underwent 64 slice spiral CT coronary angiography. To observe the pathological changes of coronary artery, And and to analyze the relationship between Gensini score and the indexes of left ventricular function. Results The left anterior descending coronary artery stenosis was the highest, and and followed by the right coronary antery. Coronary Gensini score was 0-165, average (22.6+4.7) points. With the increase of Gensini score of coronary artery, LVEF decreased gradually, LVEDV and LVESV increased gradually. The differences had statistically significant among groups(P<0.01).The Spearman correlation analysis showed positive correlation among coronary Gensini score and LVEDV and LVESV, and significant negative correlation with LVEF (P<0.01). Conclusion 64 slice spiral CT can clearly display the coronary artery stenosis. The coronary Gensini score and LVEDV and LVESV showed positive correlation, significant negative correlation with LVEF.
