摘要

目的：探讨双源CT（DSCT）和超声心动图左心室功能评价指标的相关性和一致性。材料与方法：79例患者行DSCT冠状动脉成像和超声心动图心功能检查的病人，其中39例为临床确诊为心肌梗死组（MI），另40例无急性心肌梗死作对照组，所有病人于1周内进行了超声心动图心功能检查。分析DSCT评价左心室射血分数（LVEF）、左心室短轴缩短率（LVFS）与超声心动图的相关性和一致性。结果：对照组、心肌梗死组病人DSCT与超声心动图在评价LVEF上有较强的相关性（r=0.751，r=0.718，P<0.01），LVFS测量值两种方法相关度为中等（r=0.543，r=0.606）。结论：DSCT在冠脉成像评价冠脉病变的同时可以定量评价左心室功能。

Abstract

Objective: To investigate the correlation and concordance between dual source CT(DSCT) and echocardiography in the assessment of left ventricular function parameters. Methods: Seventy-nine patients who underwent DSCT coronary angiography and echocardiography were studied in two groups. Group 1 consisted of thirty-nine consecutive patients, who were enrolled with clinic proved chronic myocardial infarction(MI) and group 2 consisted 40 consecutive patients with no prior history of acute MI as control. All of them underwent echocardiography within a week. The correlation and concordance between DSCT and echocardiography in evaluating left ventricular ejection fraction(LVEF) and left ventricular fractional shortening(LVFS) was assessed. Results: Results of DSCT and echocardiography for LVEF had a good correlation and concordance for the two groups(control group r=0.751, and MI group r=0.718, P<0.01). There was median correlation between LVFS by using DSCT and echocardiography assessment LVFS(control group r=0.543, MI group r=0.606, P<0.01). Conclusion: DSCT coronary angiography can be used in diagnosing coronary lesions and in quantitative assessment of left ventricular function parameters simultaneously.
