Abstract：Objective To investigate effect of echocardiography in diagnosis and cardiac function evaluation for patients with chronic heart failure（CHF）.Methods A total of 137 patients with CHF were selected in our hospital from January 2015 to January 2018 as observation group.137 health checkup people were selected at same period as control group.All people received echocardiography and cardiac function evaluation.Results Left ventricular ejection fraction（LVEF），cardiac index （CI） in the observation group were lower than that in the control group;while left ventricular end diastolic diameter（LVEDD），left atrial diameter（LV），HFEI score in the observation group were higher than those in the control group （P＜0.05）.LVEF，CI in patients with grade Ⅳ were lower than that patients with grade Ⅰ，Ⅱ，Ⅲ;while LVEDD，LV，HFEI scores in patients with gradeⅣ were higher than those patients with gradeⅠ，Ⅱ，Ⅲ （P＜0.05）.LVEF，CI in patients with grade Ⅲ were lower than those patients with gradeⅠ，Ⅱ;while LVEDD，LV，HFEI scores in patients with grade Ⅲ were higher than those patients with grade Ⅰ，Ⅱ （P＜0.05）.LVEF，CI in patients with gradeⅡwere lower than those patients with gradeⅠ;while LVEDD，LV，HFEI score in patients with gradeⅡwere higher than those patients with grade I （P＜0.05）.There were positive correlation between cardiac function classification and LVEF，CI（P＜0.05）.There were negative correlation between cardiac function classification and LVEDD，LV，HFEI score （P＜0.05）.Conclusion Echocardiography can be used in clinical diagnosis of CHF，which is closely related to cardiac function evaluation.
