左心室射血分数正常的心力衰竭患者临床特征及相关因素分析

Clinical features and correlated factor analysis of congestive heart failure patients with normal left ventricular ejection fraction

目的:探讨左心室射血分数正常的心力衰竭患者临床特征及相关因素。方法:选择我院心内科收治的300例心力衰竭的患者作为研究对象,根据患者左心室射血分数分为实验组和对照组两组,所有患者在入院后,了解患者基本情况,抽取患者静脉血查血常规、血脂、肝功;所有患者做超声心动图,检查心脏的基本情况。结果:实验组病例年龄高于对照组病例,吸烟、饮酒、高血压及高血脂的比率也明显高于对照组,谷丙转氨酶的浓度实验组明显低于对照组,实验组的左室内径明显小于对照组、实验组的室间隔厚度明显厚于对照组,差异均有统计学意义。结论:肝功、血压、胆固醇和超声心动图等临床指标能够为射血分数正常的心力衰竭的诊断及病情评估提供重要依据。

Objective. To investigate the clinical features and correlated factor analysis of congestive heart failure patients with normal left ventricular ejection fraction. Methods. 300 cases of acute my ocardial infarction admitted into Dept. of Cardiovascular Medicine of our hospital were included in the study. They were randomized into the control group and the treatment group according to the left ventricular ejection fraction. After hospital admission, the basic information of the routine blood tests, lipid, liver functions and echocardiography check-up of all patients should be understood. Results： Compared with the control groups, patients in the treatment group was significantly higher in age and number of cases; and the rate of smoking, alcohol consumption, hypertension, high cholesterol was also higher; the concentration of acrylic transaminase in the treatment group was obviously lower; and the left ventricular diameter was smaller; but the interventricular septum thickness was thicker. There was statistical differences between both groups. Conclusion. The clin- ical indicators of liver function, blood pressure, cholesterol, echocardiography, and the like, may be important in the diagnosis and evaluation of HFNEF.
