摘要: 目的:探讨双源CT定量评价冠心病合并Ⅱ型糖尿病左心功能的价值。方法:应用双源CT对152例伴有Ⅱ型糖尿病(76例)和不伴糖尿病(76例)冠心病患者的左心功能及冠脉特点进行对照研究;其中58例在三天内行心脏双源CT和超声心动图检查,比较双源CT与超声心动图两种方法所测得左心功能各参数的相关性。结果:双源CT和超声心动图所测左心功能各指标EDV、ESV、SV、EF相关性高(r=0.702~0.898),差异无统计学意义(P>0.05);冠心病合并Ⅱ型糖尿病组的左心功能指标EDV、ESV、MM值均较非糖尿病组高,但EF值较低,差异有统计学意义(P<0.05);冠心病合并Ⅱ型糖尿病组钙化积分较非糖尿病组明显增高,糖尿病组三支病变、重度狭窄、完全闭塞明显多于非糖尿病组,非糖尿病组单支病变、轻度狭窄多见。结论:双源CT是一种评价左心功能准确可行的方法;能一站式评估左心功能和冠脉病变特点。冠心病合并Ⅱ型糖尿病左心功能减退,冠脉病变复杂,累及血管范围广且严重。Abstract: Objective: To explore the value of DSCT in quantitative assessment of left ventricular function of coronary heart disease with T2DM.Methods: All of 152 CHD patients including 76 cases with T2DM and 76 cases without DM were performed angiographies by DSCT.Then the left ventricular function and characteristics of coronary artery were analyzed and compared between two groups.58 cases of them underwent cardiac DSCT and echocardiography examination within three days.Compared the correlations between DSCT and echocardiography in quantitative assessment of left ventricular functional parameters.Results: DSCT and echocardiography had good correlation for EF(r=0.702),ESV(r=0.874),SV(r=0.828) and EDV(r=0.898).There was no significant difference among the measurements between DSCT and echocardiography(P>0.05).The ESV and EDV measured by DSCT in the T2DM group were higher than that in non-DM group,while the EF was lower in the T2DM group.There was statistically significant between two groups(P<0.05).Calcification score had significant increase in T2DM group as compared with that in non-DM group.Three branch vessel lesion,severe stenosis and total occlusion of CHD with T2DM group have much more than that of CHD with non-DM group,while CHD with non-DM group have more one-vessel lesion and mild stenosis.Conclusion: DSCT is an accurate and feasible methods to assess the left ventricular function.The data obtained from one time coronary artery angiography can not only be used to evaluate left ventricular function but also to analysis the characteristics of coronary artery lesion.Compared with non-DM patients,the T2DM patients have more,extensive and severe coronary artery lesion and worse left ventricular function.
