【摘要】 目的研究多层螺旋CT冠状动脉造影在冠状动脉狭窄及其心肌功能。方法选取2016年10月至2017年8月高密市人民医院收治的冠状动脉狭窄患者68例为研究对象。共评价476支(580段)冠状动脉。冠状动脉狭窄患者分别行选择性冠状动脉造影、多层螺旋CT冠状动脉造影。观察患者的冠状动脉造影检查结果及心肌功能。结果选择性冠状动脉造影检查共检出232段狭窄,其中,轻度狭窄172段,中度狭窄46段,重度狭窄14段;多层螺旋CT冠状动脉造影共检出230段狭窄,171段轻度狭窄,45段中度狭窄,14段重度狭窄,敏感性98.74%,差异无统计学意义(P>0.05)。患者的心输出量(CO)(3.24±0.79)L/min,每搏输出量(SV)(46.0±11.7)ml。结论多层螺旋CT冠状动脉造影用于冠状动脉狭窄诊断,敏感性较高,可准确评估患者的心肌功能。更多还原

【Abstract】 Objective To study the coronary artery stenosis and its myocardial function by multislice spiral CT coronary angiography. Methods Sixty-eight patients with coronary artery stenosis admitted in our hospital from October 2016 to August-2017 were selected as the subjects. A total of 476( 580 segments)coronary arteries were evaluated. Selective coronary angiography and multi-slice spiral CT coronary angiography were performed in patients with coronary artery stenosis. The results of coronary angiography and myocardial function were observed. Results Two hundred thirty-two segments were detected by selective coronary angiography,including 172 mild stenosis,46 moderate stenosis and 14 severe stenosis,230 segment stenosis,171 mild stenosis,45 moderate stenosis,14 severe stenosis and 98. 74% sensitivity( P > 0. 05). The cardiac output( CO)( 3. 24 ± 0. 79) L/min,stroke output( SV)( 46 ± 11. 7) ml. Conclusion Multislice spiral CT coronary angiography is of high sensitivity in the diagnosis of coronary artery stenosis and can accurately assess the myocardial function of patients.更多还原
