目的:通过16层螺旋CT左心功能容积数据与超声左心功能容积数据的对比,初步探讨服用硝酸甘油对CT左心功能的影响。方法:选择100例8 h内同时进行了MSCT冠状动脉成像及超声心动图检查的患者,前者服用硝酸甘油,后者无服用硝酸甘油,对比两者左心功能容积数据的相关性;对比患者在服药前与服药5min后冠脉成像扫描时心率。结果:①未服药时心率(65.27±9.9)time/min)与服药5 min后(P>0.05)。结论:16层螺旋CT冠脉成像时服用硝酸甘油对其左心功能的定量评估无影响。
OBJECTIVE: To compare the effect of nitroglycerin on left ventricular function in patients with left ventricular dysfunction by comparing the left ventricular functional volume data and left ventricular functional volume data of 16-slice spiral CT. Methods: One hundred patients who underwent both MSCT coronary angiography and echocardiography within 8 h were enrolled. The former received nitroglycerin, while the other did not take nitroglycerin. The correlation between the two data was compared. Before taking the medication and coronary artery imaging 5min after heart rate. Results: (1) The heart rate (65.27 ± 9.9) / min after taking medicine and 5 minutes after taking medicine (P> 0.05). CONCLUSION: Nitroglycerin has no effect on the quantitative assessment of left ventricular function in 16-slice spiral CT coronary angiography.
