摘  要:目的观察选择性β1受体阻滞剂美托洛尔在慢性阻塞性肺疾病(COPD)治疗中的有效性及安全性。方法选择2012年9月至2013年11月在我院住院治疗的COPDЩ级(稳定期)伴或不伴冠心病患者80例,应用随机数字表将患者分成美托洛尔治疗组和常规治疗组,每组40例。常规治疗组采用常规治疗。美托洛尔治疗组在常规治疗基础上加用美托洛尔片,初始剂量为美托洛尔12.5mg/d,根据心率及耐受程度逐步滴定至合适剂量,清晨静息心率55—60次/min即认为达到目标剂量,美托洛尔连续用药12个月。观察记录治疗前后的血气分析、肺功能指标,以及6min步行试验(6MWT)和进行慢性肺疾病评估测试(CAT)评分。结果(1)两组血气分析和肺功能指标比较:美托洛尔治疗组治疗前、后动脉血氧分压(PaO2)、动脉血二氧化碳分压(PaCO2)以及肺功能1秒用力呼气容积(FEV1)占预计值%分另0为(75.92±10.78)、(74.86±11.21)mmHg,(46.28±8.28)、(47.46±10.22)mmHg和(45.45±4.68)%、(43.32±4.84)%,相比于常规治疗组治疗前后[(70.23±6.45)、(72.36±7.28)mmHg,(44.54±8.89)、(42.36±7.45)mmHg和(44.23±4.68)%、(42.58±4.24)%],两组治疗前后组间比较差异均无统计学意义(P均〉0.05);治疗后两组比较差异也无统计学意义(P均〉0.05)。(2)两组6MWT和CAT评分比较:美托洛尔治疗组与常规治疗组相比,运动耐力[美托洛尔治疗组治疗前后6MWT为(287±23)、(384±34)m,常规治疗组治疗前后为(284±25)、(295±21)m,美托洛尔治疗后较治疗前有明显提高和改善(t=4.068,P〈0.05),改善效果较常规治疗组好(t=4.643,P〈0.05)。美托洛尔治疗组的生活质量[治疗前后CAT评分为(21±7)、(17±6)分],较常规治疗组[(22±5)、(20±6�Objective To evaluate the safety and effectiveness of the treatment by selective β1 receptor blockers on patients with chronic obstructive pulmonary disease (COPD). Methods Eighty cases of COPD III (stable period) inpatient with or without coronary heart disease were collected in The Second People's Hospital of Shanghai from September 2012 to November 2013. The patients were randomly divided into testing group (Metoprolol treatment group ) and control group (regular treatment group ) with 40 cases for each group. Metoprolol group therapy based on the use of conventional metoprolol tablets, an initial dose of metoprolol 12. 5 mg/d ,titrated to the appropriate dose based on heart rate and tolerance of the morning resting heart rate of 55 to 60 times/min that reached the target dose of metoprolol continuous medication for 12 months. Blood gas analysis were recorded before and after treatment, pulmonary function, and 6 min walk test (6MWT) and were chronic lung disease Assessment Test ( CAT ) Rating. The control group was administrated regular treatment while the testing group added small dose of Metoprolol with titration to an appropriate dose on this basis. 12 months in a row, and assessed the end stage. Results ( 1 ) After the application of selective [3 receptor blockers on testing group, no statistically significant difference (P〉0.05) in the values of FEV1 in anticipation value% ( testing group : ( 45.45 ± 4. 68 ) % vs. ( 43.32 ± 4. 84 ) % ; control group : ( 44. 23 ± 4. 68 ) % vs. ( 42. 58 ±4. 24)%) ,PaO2(testing group: (75.92± 10. 78) mmHg vs. (74. 86± 11.21 ) mmHg; control group: (70. 23±6.45) mmHg vs. (72.36±7.28) mmHg) and PaCO2(testing group: (46.28±8.28) mmHg vs. (47.46 ±10.22) mmHg);control group: (44.54±8.89) mmHg vs. (42.36±7.45) mmHg) before and after treatment. But the 6MWD(testing group:(287±23) m vs. (384±34) m;control group: (284±25) m vs. (295 ± 21)
