达格列净联合美托洛尔治疗慢性心力衰竭伴2型糖尿病的效果
Effect of dapagliflozin combined with metoprolol in the treatment of chronic heart failure with type 2 diabetes mellitus
目的 探讨达格列净联合美托洛尔治疗慢性心力衰竭(chronic heart failure,CHF)伴2型糖尿病(type 2 diabetes mellitus,T2DM)的临床治疗效果。 方法 将收治的120例CHF伴T2DM患者用随机数字表法分为对照组(二甲双胍联合美托洛尔)和观察组(达格列净联合美托洛尔),每组60例。比较2组治疗前后的血流动力学、心功能、心肌损伤情况及血糖水平。 结果 治疗3个月后,观察组肺动脉楔压(pulmonary artery wedge pressure,PAWP)、肺动脉平均压(mean pulmonary artery pressure,PAMP)、右心房压(right atrial pressure,RAP)及体循环血管阻力(systemic vascular resistance,SVR)低于对照组(P<0.05),心排血量(cardiac output,CO)、心脏指数(cardiac index,CI)高于对照组(P<0.05);观察组左心室舒张末期内径(left ventricular end diastolic dimension,LEVDD)、左心室收缩末期内径(left ventricular end-systolic diameter,LVESD)低于对照组(P<0.05),左心室每搏量(left ventricular stroke volume,LVSV)、6分钟步行距离高于对照组(P<0.05);观察组乳酸脱氢酶(lactate dehydrogenase,LDH)、肌酸激酶同工酶(creatine kinase isoenzyme,CK-MB)和心肌肌钙蛋白Ⅰ(cardiac troponin Ⅰ,cTnⅠ)低于对照组(P<0.05);空腹血糖(fasting blood glucose,FPG)与糖化血红蛋白(glycosylated hemoglobin,HbA1c)水平低于对照组(P<0.05)。 结论 达格列净联合美托洛尔治疗CHF伴T2DM,可以改善患者的血流动力学指标、心功能,减轻心肌损伤,能更好地控制血糖水平,值得临床推广。
Objective To explore the clinical therapeutic effect of dapagliflozin combined with metoprolol in treating chronic heart failure (CHF) with type 2 diabetes mellitus (T2DM). Methods A total of 120 patients with CHF and T2DM were divided into 2 groups according to random number table method,including control group (60 cases,metformin combined with metoprolol) and observation group (60 cases,dapagliflozin combined with metoprolol). The hemodynamics,cardiac function,myocardial injury and blood glucose were compared between the 2 groups before and after treatment. Results After 3 months of treatment,the pulmonary artery wedge pressure (PAWP),pulmonary artery mean pressure (PAMP),right atrial pressure (RAP) and systemic vascular resistance (SVR) in the observation group were lower than those in the control group (P<0.05),while the cardiac output (CO) and cardiac index (CI) were higher than those in the control group (P<0.05). The left ventricular end-diastolic diameter (LEVDD) and left ventricular end-systolic diameter (LVESD) in the observation group were lower (P<0.05) while the left ventricular stroke volume (LVSV) and 6-minute walking distance were higher or longer (P<0.05) compared with the control group. The levels of lactate dehydrogenase (LDH),creatine kinase isoenzyme (CK-MB) and cardiac troponin Ⅰ (cTnⅠ) were lower in the observation group than those in the control group (P<0.05). The levels of fasting plasma glucose (FPG) and glycosylated hemoglobin (HbA1c) were lower compared with those in the control group (P<0.05). Conclusion The combination of dapagliflozin combined with metoprolol in the treatment of CHF with T2DM can improve hemodynamic indicators and cardiac function,relieve myocardial injury,and help patients better control blood glucose.
