目的研究心衰超声指数在慢性心力衰竭诊断中的应用价值及对预后的评估价值。方法将收治的慢性心力衰竭患者480例作为研究对象，根据心功能的不同将患者分别纳入NYHAⅠ级组、NYHAⅡ级组、NYHAⅢ级组、NYHAⅣ级组，每组120例。检测四组患者的超声指标以及体液指标。结果（1）超声指标：心衰分级越差，患者的左心室射血分数、每搏量、左室内径缩短率、室壁增厚率、室间隔运动幅度越低，心衰超声指数越高；（2）体液指标：心衰分级越差，BNP、ET和cTnT含量越高；（3）心衰超声指数与BNP、ET、cTnT含量呈正相关。结论心衰超声指数能够准确判断心力衰竭分级，且与体液指标具有良好相关性，是判断心力衰竭病情及预后的理想指标。

ObjectiveTo study the application value of heart failure echocardiography index in diagnosing chronic heart failure and its prognosis evaluation. Methods480 cases patients with chronic heart failure were enrolled, and were divided into NYHA stage Ⅰgroup, NYHA stage Ⅱgroup, NYHA stage Ⅲgroup, NYHA stage Ⅳgroup according to different heart function, with 120 cases in each group. Ultrasound indexes and fluid index of the four groups were detected. Results(1) Ultrasound index: as the heart failure classification worse, left ventricular ejection fraction, cardiac output, left ventricle shortening, wall thickening rate, amplitude of interventricular septal motion were lower; heart failure echocardiography index was higher; (2) Fluid index: as the heart failure classification worse, BNP, ET and cTnT contents were higher; (3) Heart failure echocardiography index was positively correlated with BNP, ET, cTnT contents. ConclusionsHeart failure echocardiography index can accurately judge the classification of heart failure and has good correlation with body fluid index; it′s an ideal indicators for judging the severity and prognosis of heart failure.
