摘  要:目的探讨影响脓毒性休克患者左心室舒张功能不全(LVDD)的相关因素及其对临床预后的影响。方法选取2014年6月至2015年12月浙江省人民医院ICU收治的127例脓毒性休克患者,按照舒张功能分为LVDD组(49例)和对照组(78例),对照组为左心室舒张功能正常患者。对两组患者的一般资料进行比较。于入ICU 24 h内行超声心动图检查,结合二尖瓣环舒张早期运动峰值速度(E’)和二尖瓣口舒张早期血流峰值流速/二尖瓣环舒张早期运动峰值速度(E/E’)作为评价脓毒性休克患者LVDD的指标。运用Pearson简单相关分析探讨影响脓毒性休克患者LVDD的相关因素,采用Logistic回归分析脓毒性休克患者死亡的危险因素。结果两组患者在年龄[(63±14)岁vs.(58±18)岁]、入ICU时收缩压[(90±18)mmHg vs.(99±18)mmHg]、冠状动脉粥样硬化性心脏病(CHD)(15/49 vs.12/78)、血肌酐[(188±96)μmol/L vs.(116±92)μmol/L]、急性病生理学与长期健康评价(APACHE)Ⅱ评分[(21±5)分vs.(17±6)分]、血浆脑利钠肽(BNP)[(178±84)ng/L vs.(355±128)ng/L]、左室收缩末期内径(LVESD)[(34±8)mm vs.(31±5)mm]、室间隔厚度(IVST)[(10.1±1.9)mm vs.(9.4±1.4)mm]、左室后壁厚度(PWT)[(10.2±1.5)mm vs.(9.6±1.2)mm]、左室侧壁二尖瓣环收缩期运动峰值速度(S’)[(9.0±3.0)cm/s vs.(11.4±3.6)cm/s]、E’[(7.3±2.3)cm/s vs.(12.3±3.6)cm/s]及E/E’[(11.6±4.0)vs.(6.8±2.6)]方面比较,差异均有统计学意义(P均<0.05)。相关分析显示:年龄、高血压、CHD、血浆BNP和APACHEⅡ评分与E/E’呈正相关(r=0.302、0.289、0.277、0.418、0.290,P均<0.05);而入ICU收缩压和左室射血分数(LVEF)与E/E’呈负相关(r=-0.239、-0.284,P均<0.05)。Logistic回归分析统计结果显示:年龄[OR=1.040,95%CI(1.020,1.071)]、血乳酸[OR=1.492,95%CI(1.176,1.732)]、血浆BNP[OR=2.051,95%CI(1.232,2.964)]、E/E’[OR=1.362,95%CI(1.122,1.534)]和APACHEⅡ评分[OR=2.370,95%CI(1.131,3.674)]是预测脓毒性休克患者死亡的独�Objective To study the determinants of left ventricular diastolic dysfunction (LVDD) and investigate its association with mortality in patients with septic shock. Methods Totally 127 patients with septic shock in Zhejiang Provincial People's Hospital recruited from June 2014 to December 2015 were divided into the LVDD group (49 cases) and control group as patients with normal left ventricular diastolic function (78 cases). General data of the two groups were compared. According to diastolic function underwent trans-thoracic echocardiography examination within 24 h after admission to ICU, LVDD was assessed as the combination early diastolic mitral annulus velocity (E3 with the ratio of early diastolic mitral inflow velocity to early diastolic mitral annulus velocity (E/E'). The related factors of LVDD in patients with septic shock were analyzed by Pearson simple correlation, and the risk factors associated with mortality in patients with septic shock were evaluated by Logistic regression. Results Compared with the control group, the age [(63±14)years vs. (58±18)years], systolic blood pressure admitted to ICU [ (90±18) mmHg vs. (99±18) mmHg], coronary atherosclerotic heart disease (CHD) (15/49 vs. 12 / 78), serum creatinine [(188±96) μmol/L vs. (116±92)μmol/L], acute physiology and chronic health evaluation (APACHE) ]/ scores [(21±5) vs. (17±6)], plasma brain natriuretic peptide (BNP) [(178±84) ng/ L vs. (355±128) ng/ L], left ventricular end systolic diameter (LVESD) [(34±8)mm vs. (31±5)mm], interventrieular septal thickness (IVST) [(10.1±1.9)mm vs. (9.4±1.4) mm], left ventricular posterior wall thickness (PWT) [(10.2±1.5)mm vs. (9.6±1.2)mm[, mitral annular systolic velocity peak (S') [(9.0±3.0) cm / s vs. (11.4±3.6) cm / s], E' [(7.3±2.3) cm / s vs. (12.3 ± 3.6)em/s] and E/E' [(11.6 ± 4.0) vs. (6.8±2.6)] in the LVDD group were significantly dif
