The role of cardiac ultrasound in the diagnosis and evaluation of cardiac function in patients with chronic heart failure
心脏超声应用于慢性心衰患者诊断及心脏功能评价中的作用研究

摘要

目的 在诊断慢性心衰与评价心脏功能当中心脏超声的应用价值。方法 纳入72例慢性心衰患者，将其纳入至研究组，另外选取72例健康体检者将其纳入对照组，比较等级不同慢性心衰患者、对照组和研究组患者超声诊断参数和NT-proBN值。结果 慢性心衰患者Ⅳ级患者共22例，Ⅲ级患者共25例，Ⅰ级和Ⅱ级患者，共计有25例，Ⅳ级患者的左心室内径、NT-proBNP、HFEI及左心室舒张末期内径，均要高于Ⅲ级、Ⅰ级和Ⅱ级，Ⅳ级左室射血分数比Ⅲ级、Ⅰ级和Ⅱ级低，（P＜0.05）。对两组NT-proBNP、HFEI、左心室舒张末期及左心室内径比较，研究组高，对两组左室射血分数比较，研究组低，（P＜0.05）。结论 在诊断慢性心衰当中，心脏超声应用价值较高，其可以将患者的心脏功能反应出来。

Abstract

Objective: To evaluate the application value of cardiac ultrasound in the diagnosis of chronic heart failure and the evaluation of cardiac function. Method: 72 patients with chronic heart failure were included in the study group, and another 72 healthy individuals were selected to be included in the control group. The ultrasound diagnostic parameters and NT proBN values of patients with different levels of chronic heart failure, the control group, and the study group were compared. Result: There were 22 patients with chronic heart failure in grade IV, 25 patients with grade III, and 25 patients with grade I and II. The left ventricular diameter, NT proBNP, HFEI, and left ventricular end diastolic diameter of grade IV patients were higher than those of grade III, grade I, and grade II, and the left ventricular ejection fraction of grade IV was lower than that of grade III, grade I, and grade II (P<0.05). Compared with the two groups of NT proBNP, HFEI, left ventricular end diastolic and left ventricular diameter, the study group showed a higher score, while the study group showed a lower left ventricular ejection fraction (P<0.05).
Conclusion  : In the diagnosis of chronic heart failure, cardiac ultrasound has a high value as it can reflect the patient's cardiac function.
