摘  要:目的探讨妊娠合并心脏病患者左心室结构及功能与血清基质金属蛋白酶1(MMP-1)及其组织抑制物1(TIMP-1)水平的相关性,评价MMP-1及TIMP-1在妊娠合并心脏病患者心脏重新构建过程中的临床价值。方法收集2007年10月至2008年7月上海交通大学医学院附属仁济医院产科收治的孕晚期妊娠合并心脏病孕妇58例,根据左心室肥大和肺动脉高压情况分为:A组:有心慌、胸闷等临床症状,但无左心室肥大者17例;B组:有心慌、胸闷等临床症状及左心室肥大,但无肺动脉高压者15例;C组:有心慌、胸闷等临床症状及左心室肥大,且有肺动脉高压者26例,其中C组患者根据肺动脉压情况又分为轻度[肺动脉压30~49mmHg(1mmHg=0.133kPa)]11例,中度(肺动脉压50~79mmHg)9例,重度(肺动脉压≥80mmHg)6例。另选同期正常妊娠妇女15例作为埘照组。采用多普勒彩色超声心动仪分别测定各组孕妇妊娠晚期的左心室结构和功能指标,包括左心室重量指数(LVMI)、舒张末期内径(LVEDd)、左心室射血分数(EF)、二尖瓣舒张早期充盈峰(E峰)、舒张晚期充盈峰(A峰)及其比值(E/A);采用酶联免疫法测定各组孕妇血清MMP-1和TIMP-1水平。结果(1)C组孕妇LVMI为(148±7)g/m^2、LVEDd为(58.9±3.5)mm,E峰为(50±10)cm/s,明显高于对照组及A组、B组(P〈0.01);EF为(51.0±4.4)%,E/A比值为(0.6±0.3),与对照组及A组、B组比较,均显著降低(P〈0.01)。(2)C组重度肺动脉高压孕妇LVMI为(150±7)g/m^2、LVEDd为(69.7±3.4)min,均明显高于轻度及中度孕妇(P〈0.01),A峰[(86±8)cm/s]升高(P〈0.05);E峰[(44±9)cm/s]下降(P〈0.05),EF为(45.6±2.6)%,E/A比值为(0.52±0.17),均明显低于轻度及中度孕妇(P〈0.01)。(3)C组孕妇血清MMP-1[(41±10Objective To analyse the relationship between the left ventricular (LV) structure, function and changes of concentration of serum matrix metalloproteinase-1 ( MMP-1 ) , tissue inhibitor of matrix metalloproteinase-1 ( T1MP-1 ) , and evaluate the value of the change of serum MMP-1 and serum TIMP-1 in ventricular remodeling of pregnant women complicating cardiac disease. Methods Fifty-eight cases of pregnant women with cardiac disease divided into three groups [ group A had 17 cases who had clinical manifestations and no left ventricular hypertrophy (LVH) ], group B had 15 cases who had clinical manifestations and LVH but no pulmonary hypertension ( PH ) , group C had 26 cases who had clinical manifestations, LVH and PH which divided into three groups again : 11 cases of slight group [ PH from 30 - 49 mm Hg ( 1 mm Hg =0. 133 kPa) ] ,9 cases of moderate group ( PH from 50 - 79 mm Hg) and 6 cases of severe group (PH ≥ 80 mm Hg ). Fifteen healthy pregnant women acted as control group. The left ventricular structure and function [ (left ventricular mass index (LVMI), left ventricular end-diastolic diameter (LVEDd) ,Ejection fraction (EF) ,E peak (E), A peak (A) and E/A], pulmonary pressure and plasma MMP-1, TIMP-1 values were determined in the third trimester of pregnancy. Results ( 1 ) LVMI ( 148 ±7) g/m^2 and LVEDd (58.9 ±3.5) mm in group C increased significantly (totally P 〈0. 01 ) , EF ( 51.0 ± 4.4 ) % decreased signifcantly ( P 〈 0. 01 ), E ( 50 ± 10 ) cm/s decreased significantly ( P 〈 0. 01 ), A (81 ± 13) cm/s increased (P 〈 0.05) and E/A(0.6 ± 0.3) decreased significantly (P 〈 0.01 ) compared with normal subjects, group A and group B. (2) LVMI ( 150 ± 7 ) g/m^2, LVEDd ( 69. 7 ± 3.4 ) mm in severe pulmonary hypertension group increased significantly( P 〈 0. 01 ), EF(45. 6 ± 2. 6 )% decreased significantly(P 〈0.01),E(44 ±9) cm/s decreased(P 〈0.05) , A
