摘要
目的 观察卡维地洛与倍他乐克对高血压性心脏病患者心肌质量的影响。方法选取100例高血压性心脏病患者,随机分成卡维地洛组54例、倍他乐克组46例。卡维地洛组服用卡维地洛,倍他乐克组服用倍他乐克,疗程均为12个月。分别于治疗前和治疗后测定患者左心室舒张末期内径(LVEDD),左心室收缩末期内径(LVESD),左心室射血分数(LVEF),室间隔厚度(IVST)及左心室后壁厚度(LVPWT)。计算左心室心肌质量(LVM)以及左心室心肌质量指数(LVMI)。结果两组治疗后较治疗前LVEDD减小[倍他乐克组(46.70±3.21)mm减小为(43.60±4.43)mm,t=18.143,P〈0.01;卡维地洛组(46.50±3.18)mm减小为(42.5±2.56)mm,t=18.232,P〈0.01];IVST变薄[倍他乐克组(12.01±1.56)mm变为(9.68±1.65)mm,卡维地洛组(11.59±1.54)mm变为(9.05±1.04)mm],差异有统计学意义(t:12.785,P〈O.01;t=7.865,P〈0.01)。LVEF增高[倍他乐克组(50.23±7.88)%增至(52.89±8.78)%,卡维地洛组(50.22±7.89)%增至(54.65±8.87%)%]。卡维地洛组LVMI由(133.75±25.89)g/m。减低为治疗后(109.25±22.53)g/m。,差异有统计学意义(t=4.987,P〈0.01);倍他乐克组LVMI由(134.76±25.87)g/m。减低为治疗后(119.78±23.65.53)g/m。,差异有统计学意义(t=5.689,P〈0.01)。治疗后卡维地洛组较倍他乐克组心功能各指标改善明显(P均〈0.05)。结论卡维地洛与倍他乐克均有减轻高血压性心脏病患者心肌质量的作用。
Objective To observe the effect of carvedilol and motoprolol on the weight of cardiac muscle in patients with hypertensive heart disease. Methods One hundred patients with hypertensive heart disease were divided into two groups by random number and treated with carvedilol( n = 54) and motoprolol( n = 46) respectively for 12 months. Data were recorded (left ventricular end-diastolic dimension( LVEDD), left ventricular end-systolic dimension ( LVESD ), left ventricular ejection fraction ( LVEF ), interventricular septal thickness (IVST), and left ventricular posterior wall thickness(LVPWT) ) before and after the treatment. Left ventricular muscle mass (LVW) ,left ventricular mass index (LVWI) were calculated. Results After treatment, both groups improved with declined LVEDD ( motoprolol group : (43.60± 4.43 ) mm vs. (46.70 ± 3.21 ) mm, t = 18. 143, P 〈 0.01 ; carvedilol group : ( 42. 50± 2. 56 ) mm vs. ( 46. 5± 3.18 ) mm, t = 18. 232, P 〈 0. 01 ), thinner IVST ( motoprolol group : (9. 68 ± 1.65 ) mm vs. ( 12. 01 ± 1.56 ) mm, t = 12. 785, P 〈 0. 01 ; carvedilol group:(9.05 ±1.04) mm vs. (11.59 ± 1.54) mm,t =7.865,P 〈0.01) ,and increased LVEF (motoprolol group: (52. 89 ±8.78)% vs. (50.23 ±7.88)%;carvedilol group: (54.65 ± 8.87%)% vs. (50.22 ±7.89)%). In the carvedilol treatment group, LVMI significantly (t = 4.987, P 〈 0.01 ) declined from (133.75 ±25.89)g/m2 to (109. 25 ±22. 53) g/m2. In the motoprolol treatment group, LVMI declined from ( 134. 76 ±25.87) g/m2 to (119. 78 ±23.65.53) g/m2 (t =5. 689,P 〈0. 01). After the treatment,each index of carvedilol group improved significantly compared with metoprolol group ( P 〈 0.05 ) . Conclusion Both medications are able to reduce the weight of cardiac muscle of patients with hypertensive heart disease, and carvedilol is better than motoprolol.
