射血分数降低的心衰与射血分数保留的心衰临床特征分析

目的：通过总结射血分数降低的心衰（HFrEF）和射血分数保留的心衰（HFpEF）两种类型的心衰合并症及相关指标,探索其临床特征.方法：回顾性分析85例心衰患者的资料,根据Framingham标准确诊为心力衰竭,超声心动图检测LVEF为≥50％为HFpEF组,LVEF＜50％为HFrEF组,对其临床特点进行分析.结果：85例患者中有51例是HFrEF患者,年龄（64.96±11.52）岁,其中男性34例（66.7％）,女性17例（33.33％）;34例是HFpEF患者,年龄（71.09士10.86）岁,其中男性14例（41.28％）,女性20例（58.82％）.同组之间性别、年龄比较均有差异（P＜0.05）.两组中EF值、LVD值、NTproBNP水平、合并心肌病、合并心律失常比较均有差异（P＜0.05）.两组间不同性别患者NHYA分级Ⅱ级分布与Ⅲ、Ⅳ级分布均有不同.结论：HFpEF组年龄高于HFrEF组;两组间患者NHYA分级因性别不同,分布亦不同;HFrEF组中LVD值和NTproBNP水平较高;合并症对HFrEF组的总体影响较HFpEF组高.

Clinical characteristics analysis of heart failure with reduced ejection fraction and heart failure with reserved ejection fraction

Objective; To analyze the clinical characteristics of heart failure with reduced ejection frac- tion （HFrEF） and heart failure with preserved ejection fraction （HFpEF） based on their related in dicators. Methods： Data of 85 cases of heart failure patients were retrospectively analyzed, patients diagnosed as heart failure by Framingham standard and LVEF ≥50% by the detection of dynamic electrocardiogram （DCG） were selected as HFpEF group, while LVEF〈50% as HFrEF Group, and their clinical characteristics were analyzed. Results. Of the 85 heart failure patients, 51 be longed to HFrEF with the age of （64.96±11.52） years old, and 34 were male and 17 were female 34 belonged to HFpEF with the age of （71.09±10.86）years old, and 14 were male and 20 were fe- male. There were differences between gender and age in the same group （P〈0.05） there were significant differences between the values of EF and LVD, NTproBNP, Merger of cardiomyopathy and arrhythmia in both groups （P〈0.05）. Also the NHYA grading, the distribution of II grading and III or IV grading were different. Conclusion. The age of HfpEF is higher than that of HfrEF, NHYA grading varies with age and distribution. LVD values and NTproBNP levels are higher in HfrEF group, and the effect of complications on HfrEF group is greater than that on HfpEF group.
