【摘要】 目的分析射血分数保留型心力衰竭(HFpEF)合并T2DM病人的冠状动脉造影术(CAG)结果以及病人的临床特点。方法选取2016年3月至2017年2月青岛大学附属医院心血管内科住院治疗的HFpEF病人165例,根据病人是否合并T2DM,分为T2DM-HFpEF组(n=48)和单纯HFpEF组(n=117),收集并比较2组病人的临床资料、实验室生化指标、CAG及心脏超声结果。结果 T2DM-HFpEF组中女性、NYHA分级Ⅲ～Ⅳ级、高血压、陈旧性心肌梗死、冠状动脉双支及双支以上病变比例均显著高于单纯HFpEF组,差异有统计学意义(P <0. 05)。单纯HFpEF组病人的住院天数、单核细胞计数、Hb水平、前降支(LAD)及回旋支(LCX)狭窄程度均优于T2DM-HFpEF组,差异有统计学意义(P <0. 05)。结论 HFpEF合并T2DM病人的住院时间较单纯HFpEF病人长,其冠状动脉双支及双支以上病变比例较单纯HFpEF病人高,LAD和LCX狭窄程度较单纯HFpEF病人严重。更多还原

【Abstract】 Objective To analyze the results of coronary angiography(CAG)and the clinical characteristics of the patients with heart failure preserved ejection fraction(HFpEF)combined with type 2 diabetes mellitus(T2DM). Methods A total of 165 HFpEF patients in the Affiliated Hospital of Qingdao University from March 2016 to February 2017 were enrolled in this study. The patients were divided into T2DM-HFpEF group(n=48)and HFpEF group(n=117)according to whether they presented with T2DM or not. The clinical data,biochemical indicators,CAG and echocardiography results of the two groups were collected and compared. Results The ratio of women,grade Ⅲ-Ⅳ of New York Heart Association(NYHA),hypertension,old myocardial infarction,two and more lesions of the coronary artery in T2DM-HFpEF group was significantly higher than that in HFpEF group(P <0. 05). The duration of hospitalization,the levels of monocyte and hemoglobin,and the stenosis of left anterior descending artery(LAD)and left circumflex(LCX)in HFpEF group were better than those in T2DM-HFpEF group(P < 0. 05). Conclusions Compared with HFpEF patients,T2DM-HFpEF patients have the longer hospitalization days,the larger ratio of people who have two and more lesions of the coronary artery,and the worse stenosis of LAD and LCX.更多还原
