[摘要]目的 探討心臟超聲在慢性心力衰竭（CHF）患者診斷及心臟功能評價中的作用。方法 選取我院2015年1月～2018年1月診療的137例CHF患者為觀察組，同期健康體檢人員137例為對照組，均行心臟超聲檢查和心臟功能評價。結果 觀察組左室射血分數（LVEF）、心臟指數（CI）低于對照組;左室舒張末期內徑（LVEDD）、左房內徑（LV）、HFEI評分高于對照組（P<0.05）。心功能Ⅳ級患者LVEF、CI低于心功能Ⅰ、Ⅱ、Ⅲ級患者;LVEDD、LV、HFEI評分高于心功能級Ⅰ、Ⅱ、Ⅲ級患者（P<0.05）。心功能Ⅲ級患者LVEF、CI低于心功能Ⅰ、Ⅱ級患者;LVEDD、LV、HFEI評分高于心功能Ⅰ、Ⅱ級患者（P<0.05）。心功能Ⅱ級患者LVEF、CI低于心功能Ⅰ級患者;LVEDD、LV、HFEI評分高于心功能Ⅰ級患者（P<0.05）。心臟功能分級與LVEF、CI成正相關性（P<0.05）;與LVEDD、LV、HFEI評分成負相關性（P<0.05）。結論 心臟超聲可用于CHF的臨床診斷，與心臟功能評價密切相關。

[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 grade Ⅳ were higher than those patients with grade Ⅰ， 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 grade Ⅱwere lower than those patients with grade Ⅰ; while LVEDD， LV， HFEI score in patients with grade Ⅱwere 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.

慢性心力衰竭（CHF）是老年常見的一種綜合性心血管疾病，也是各種心臟疾病演化的最終階段，是造成患者死亡的主要病因[1-2]，及早診斷和治療，有助于改善患者的預后。但CHF發病早期并無明顯的臨床表征，極易造成漏診，因而亟待尋求一種更有效的診斷方法。心臟超聲是目前CHF診斷的重要手段[3-4]，可利用超聲指數對疾病嚴重程度進行準確判斷，以輔助醫生開展臨床治療，但心臟超聲與患者心臟功能的相關性研究報道未見。本研究探討心臟超聲在CHF患者診斷及心臟功能評價中的作用，現報道如下。
