左室射血分数降低的冠心病患者冠状动脉造影观察

目的 探讨左室射血分数降低的冠心病患者的冠状动脉造影情况.方法 回顾性分析120例冠心病患者临床资料,依据左室射血分数降低情况分为观察组和对照组.结果 观察组多支病变、前降支、回旋支、左主干病变发生率均明显高于对照组（均P＜0.05）,Gensini积分明显高于对照组（P＜0.05）.结论 临床密切注意左室射血分数变化可以为治疗提供可靠的理论依据.

The observation of coronary angiography detection in coronary heart disease patients with left ventricular ejection fraction decreasing

Objective To explore coronary angiography detection in coronary heart disease patients with left ventricular ejection fraction decreasing. Methods The clinical data of 120 coronary heart disease patients were retrospectively analyzed. And the patients were divided into observation group and control group by decreasing of left ventricular ejection fraction. Results The incidence rate of more affection, anterior descending branch, convolution branch,left bole affection were higher than control group;The Gensini points of detection group were higher than control group( P ＜ 0. 05) ,and the difference was statistical significance. Conclusion Close attention on the changes of left ventricular ejection fraction in the clinic could provide reliable theory base.
