目的：探讨单硝酸异山梨酯缓释胶囊治疗心绞痛的临床价值。方法：选取2014年3月-2015年5月本院接诊的200例心绞痛患者作为研究对象，采用抽签法随机抽取100例患者采用心绞痛常规治疗方法进行治疗，设为对照组；另100例患者在心绞痛常规治疗的基础上给予单硝酸异山梨酯缓释胶囊治疗，设为观察组。分别观察两组患者治疗后的恢复效果以及并发症的发生情况。结果：观察组总有效率为97.0%，明显高于对照组的86.0%，组间对比差异具有统计学意义（X2=7.779；P＜0.05）；观察组患者用药时间和症状消失时间均少于对照组，组间对比差异具有统计学意义（P＜0.05）。结论：硝酸异山梨酯缓释胶囊对心绞痛的临床治疗具有重大意义，不仅效果明显，还能起到一定的预防作用，值得推广和应用。
Objective: To investigate the clinical value of isosorbide mononitrate sustained release capsules in the treatment of angina pectoris. Methods: From March 2014 to May 2015, 200 cases of angina pectoris admitted to our hospital were selected as study objects. 100 patients were randomly selected by lottery method and treated with routine angina pectoris treatment. The other 100 patients In the conventional treatment of angina given isosorbide mononitrate sustained-release capsules treatment, as the observation group. Respectively observed after treatment in both groups, the recovery effect and the occurrence of complications. Results: The total effective rate in the observation group was 97.0%, which was significantly higher than that in the control group (86.0%). The differences between the two groups were statistically significant (X2 = 7.779; P <0.05). The observation group had less medication time and less symptoms Control group, the difference between groups was statistically significant (P <0.05). Conclusion: Isosorbide dinitrate sustained-release capsules are of great significance for the clinical treatment of angina pectoris. Not only the effect is obvious, but also play a preventive role, which is worth promoting and application.
