Objective To explore the effect of systematic nursing on the psychological state and pain control of patients with angina pectoris in coronary heart disease.Methods This study selected 82 patients with angina pectoris in coronary heart disease admitted to a hospital in Zhengzhou from December 2017 to February 2019 as the research subjects.A random number table was used to divide the patients into an observation group and a control group

with 41 cases in each group.The patients in the control group were given routine care

and the patients in the observation group were given systematic nursing care in addition.At 1 week of intervention

the self-rating anxiety scale（SAS）and self-rating depression scale（SDS）were used to assess the psychological state of the two groups of patients

and the pain control effects of the two groups of patients were compared at the same time.Results After nursing

the SAS and SDS scores of the observation group were（12.41±2.31）and（13.34±2.34）points

which were lower than the（17.38±2.01）and（17.47±2.35）points of the control group.The SAS and SDS scores of both groups were lower than before nursing

and the differences were statistically significant（P<0.05）.The effective rate of pain control in the observation group was 97.56%

higher than 80.48%in the control group

and the difference was statistically significant（P<0.05）.Conclusion Systematic nursing plays an important role in improving the psychological state and pain control for patients with angina pectoris in coronary heart disease.The clinical effect is remarkable

and it is worth wider clinical application.
