摘 要:目的 对比血管紧张素Ⅱ受体拮抗剂(AⅡA)和血管紧张素转换酶抑制剂(ACEI)对急性前壁心肌梗死(AMI)后左室整体及局部收缩功能的影响.方法 将75例首次前壁AMI患者按随机数字表法分为常规治疗组15例、卡托普利治疗组30例、缬沙坦治疗组30例,并于AMI后1和28周分别行平衡法核素心室显像,测定左室整体收缩功能(LVSF)和左室局部射血分数(LrEF1~9),了解2种药物对AMI后左室收缩功能的影响.计量资料组间及自身前后比较行t检验.结果 (1)AMI后28周时,缬沙坦治疗组与常规治疗组比较,左心室射血分数(LVEF)增加[(59.4±8.6)%与(44.9±8.4)%,t=3.87,P<0.01],左室峰射血率(LPER)升高[(3.89±1.01)舒张末期容积(EDV)/s与(2.84±1.05)EDV/s,t=4.16,P<0.01],LPER时间(LTPER)下降[(116±16)ms与(137±20)ms,t=2.16,P<0.05],而与卡托普利组比较差异无统计学意义(t=1.58,1.09,1.77,P<0.05).(2)AMI后28周与1周比较,缬沙坦组不同部位左室局部射血分数LrEF2、LrEF4、LrEF5和LrEF6均明显升高[(71.6±18.8)%与(57.0±11.4)%,t=2.11 (78.1±16.8)%与(68.9±21.0)%,t=2.06 (70.5±16.9)%与(59.9±23.4)%,t=1.99 (58.1±9.0)%与(46.0±18.9)%,t=2.43 P均<0.05].AMI后28周时,缬沙坦和卡托普利组LrEF2、LrEF3、LrEF4、LrEF5、LrEF6、LrEF7较常规治疗组均有所提高(t=1.96~2.27,P均<0.05),且2组间差异无统计学意义(t=1.06~1.77,P均>0.05).结论 血管紧张素Ⅱ受体拮抗剂缬沙坦能明显减轻前壁AMI后LVSF和LrEF的下降,且其效果与ACEI类药物卡托普利相近.Objective To compare the therapeutic effect of angiotensin Ⅱ antagonist (Valsartan)and angiotension-converting enzyme inhibitor (Captopril) for the improvement of left ventricular systolic function(LVSF) after acute myocardial infarction (AMI) at anterior wall. Methods A total of 75 patients with initial AMI at anterior wall were enlisted in the study. Patients were divided randomly into three groups: control group (n = 15), Captopril treated (n =30), and Valsartan treated (n =30). At 1 week and 28 weeks post AMI, the LVSF and left ventricular regional ejection fraction (LrEF) were measured by equilibrium radionuclide angiography (ERNA). The t-test was used to compare the dada. Results ( 1 ) At 28 weeks, left ventricular ejection fraction (LVEF) and left ventricular peak ejection rate (LPER) in Valsartan treated group were significantly increased as compared with those of control: ( 59.4 ± 8.6 ) % vs (44.9 ± 8.4)%, t = 3.87, P 〈 0.01 for LVEF (3.89 ± 1.01 ) end-diastolic volume (EDV)/s vs (2.84 ±1.05) EDV/s, t= 4.16, P 〈 0.01 for LPER). The left ventricular time to peak ejection rate (LTPER) in Valsartan treated group was significantly decreased ( ( 116 ± 16 )ms vs ( 137 ±20) ms, t =2.16, P 〈 0.05 ) as compared with control. (2)Compared with 1-week, 28-week Valsartan treated group had a significant increase inLrEF2, LrEF4, LrEF5, LrEF6: (71.6±18.8)% vs (57.0±11.4)%, t=2.11, P〈0.05 (78.1 ±16.8)% vs (68.9±21.0)%, t =2.06, P〈0.05 (70.5±16.9)% vs (59.9 ±23.4)%, t=1.99, P 〈 0.05 and (58.1 ± 9.0) % vs (46.0 ± 18.9) %, t = 2.43, P 〈 0.05, respectively. Conclusions Valsartan and Captopril are effective for the improvement of LVEF after AMI at anterior wall. The effects of the two drugs are similar.
