Effect of isosorbide mononitrate combined with metoprolol in the treatment of heart failure in patients with coronary heart disease / 中国基层医药

ABSTRACT

Objective To observe the clinical effect of isosorbide mononitrate combined with metoprolol in the treatment of coronary heart failure.Methods From January 2015 to May 2017,100 patients with coronary heart failure treated in the Second People's Hospital of Yuyao were randomly divided into two groups according to the digital table,with 50 cases in each group.The conventional group was treated with conventional therapy.The observation group was treated with isosorbide mononitrate combined with metoprolol on the basis of conventional treatment for 30 days.The clinical efficacy,cardiac function index and plasma BNP level were compared between the two groups.Results The total effective rate of the observation group was 96.0％ (48/50),which was higher than 78.0％ (39/50) in the conventional group(x2 =7.161,P ＜ 0.01).After treatment,the cardiac drainage index(CI) [(3.14 ± 0.53) L · min-1 · (m2)-1],cardiac output blood volume (CO) [(5.62 ± 0.95) L/min],each stroke volume (SV) [(79.24 ± 2.56) mL],left ventricular ejection fraction (LVEF) [(61.62 ± 4.95) ％] in the observation group were better than those in the conventional group[(2.41 ±0.45) L · min-1 · (m2)-1,(4.79 ± 0.23) L/min,(72.30 ± 2.78)mL,(53.79 ±4.23)％,t =7.043,5.696,12.318,8.066,all P ＜0.05].The BNP level of the observation group was (172.17 ± 10.36) pg/mL,which was lower than (215.47 ± 12.48) pg/mL of the conventional group (t =17.908,P ＜ 0.05).Conclusion The treatment of coronary heart failure with isosorbide mononitrate and metoprolol can improve the clinical effect and improve cardiac function.
