心脏彩超射血分数在筛选高危心衰患者的应用探讨

目的探讨心脏彩超左室射血分数在筛选心衰患者高危心脏性猝死应用中的意义。方法通过分析经我院治疗的120例心力衰竭患者心脏彩超左心室射血分数的变化情况，以更好的评价心脏功能，并实施相应的治疗措施。结果左心室射血分数〉50％，30例，0例发生猝死；左心室射血分数为41％-50％，30例，1例猝死；左心室射血分数为3l％～40％时，30例，2例猝死；左心室射血分数≤30％，30例，3例猝死。结论射血分数对于心力衰竭患者治疗以及预测心脏性猝死的风险非常重要，是一个非常关键的指标。

Colour sonography the left ventricular ejection fraction in the screening of sudden cardiac death in patients with high-risk application

Objective To study the cardiac color dopplar ultrasound left ventricular ejection fraction in the screening of sudden cardiac death for high-risk patients application significance. Methods Through the a- nalysis of the governance in our of 120 cases of patients with heart failure heart colour exceeds the left ventricular ejection fraction changes, in order to better evaluate cardiac function, and implement the corresponding treatment measures. Results The left ventricular ejection fraction 〉 50%, 30 cases, 0 case of sudden death, left ventricular ejection fraction was 41% -50%, 30 cases, 1 cases of sudden death, Left ventricular ejection fraction was 31% -40% , 30 cases, 2 cases of sudden death, left ventricular ejection fraction of 30% or less, 30 cases, 3 cases of sudden death. Conclusion Ejection fraction for sudden cardiac death screening high-risk patients is a very key indicators.
