摘要 目的探讨左心室射血分数正常心力衰竭(HFNEF)患者的临床特点及其与左心室射血分数减损心力衰竭(HFDEF)患者临床特点的差异。方法回顾性分析107例慢性心力衰竭患者的临床资料,根据心脏彩超结果分为左心室射血分数(LVEF)≥50%的HFNEF组(41例)与LVEF〈50%的HFDEF组(66例),比较两组患者的临床资料。结果HFNEF组在年龄、性别构成、合并高脂血症、肥胖、胆红素升高、高血压、扩张型心肌病方面与HFDEF组比较差异有统计学意义(P〈0.05),两组在冠心病、高血压合并冠心病、糖尿病、吸烟、肌酐升高方面比较差异无统计学意义(P〉0.05)。两组患者心房颤动、肺淤血发生情况比较差异无统计学意义(P〉0.05);HFNEF组左心室肥厚明显多于HFDEF组,心脏扩大明显少于HFDEF组,QRS时限明显短于HFDEF组,差异均有统计学意义(P〈0.05)。HFNEF组LVEF、室间隔厚度(ⅣsT)、左心室后壁厚度(LV冈【,rI')显著大于HFDEF组,而左心室舒张末期内径、左心室收缩末期内径显著小于HFDEF组,差异均有统计学意义(P〈0.05);两组患者左心房内径比较差异无统计学意义(P〉0.05)。HFNEF组患者住院期间使用率最高的3类药物分别是13.受体阻滞剂(61.0%,25/41)、利尿剂(48.8%,20/41)、钙离子拮抗剂(34.1%,14/41),HFDEF组患者分别是利尿剂(69.7%,46/66)、血管紧张素转换酶抑制剂(62.1%,41166)、洋地黄(51.5%,34/66)。HFNEF组患者住院期间病死率为2.44%(1/41),高于HFDEF组的9.09%(6/66),差异有统计学意义(P〈0.05)。结论HFNEF以老年、女性、基础疾病为高血压及冠心病者常见,易合并高脂血症、肥胖等危险因素,其心室扩大程度相对较轻,IvsT、LVPWT多增厚,药物治疗中β-受体阻滞剂、利尿剂和钙离子拮抗剂是治疗HFNEF使用率最高的药物。
