目的探讨优化重组技术在心率过快、心率波动患者冠状动脉成像中的应用价值。资料与方法回顾性分析心率过快、心率波动患者资料149例,根据心率过快程度及心率波动范围分组:A组60例,心率70～80次/min,心率波动5～10次;B组34例,心率70～80次/min,心率波动>10次;C组37例,心率>80次/min,心率波动5～10次;D组18例,心率>80次/min,心率波动>10次。选取心率<70次/min,无明显心率波动患者(心率波动<5次)60例作为对照组,比较优化重组前后各组冠状动脉图像质量,比较试验组与对照组之间冠状动脉图像质量。结果通过优化重组技术处理后,B、C两组冠状动脉图像质量较重组之前有明显改善(P<0.05),A、D两组冠状动脉图像质量重组前后无明显改善(P>0.05)。优化重组后A组图像质量与对照组图像质量无统计学差异(P>0.05),B、C、D组图像质量与对照组图像质量具有统计学意义(P<0.05)。结论大部分心率过快,心率波动的患者经过优化重组后均可满足诊断需要,而心率太快、心率波动过大的患者(心率>80次/min,心率波动>10次)成像效果差,不推荐行冠状动脉CTA检查。
Objective To investigate the value of optimized recombinant technique in coronary angiography in patients with heartbeat and heart rate fluctuation. Materials and Methods Retrospective analysis of 149 patients with fast heart rate and heart rate fluctuations, according to the degree of heart rate and heart rate fluctuation range: 60 cases in group A, heart rate 70 to 80 beats / min, heart rate fluctuations 5 to 10 times; 34 cases, heart rate 70 ~ 80 beats / min, heart rate fluctuation> 10 times; C group 37 cases, heart rate> 80 beats / min, heart rate fluctuations 5 to 10 times; D group 18 cases, heart rate> 80 beats / min, > 10 times. Sixty patients with heart rate fluctuation <5 beats) with heart rate <70 beats / min, and the coronary arteries quality of each group before and after reorganization were compared and optimized. The image quality of coronary arteries was compared between the test group and the control group. Results After optimization of the recombinant technique, there was a significant improvement in the image quality of the coronary arteries in groups B and C (P <0.05) before and after the coronary arteries were reconstructed (P> 0.05). There was no significant difference in image quality between group A and control (P> 0.05). Image quality in group B, C and D was significantly different from that of control group (P <0.05). Conclusion Most of the patients with heartbeat and heart rate fluctuation can meet the need of diagnosis after optimization and reorganization. However, the heart rate is too fast and the heart rate fluctuation is too high (heart rate> 80 beats / min, heart rate> 10) Coronary CTA examination is not recommended.
