Objective To investigate the effects of the Knowledge-Attitude-Practice（KAP） model combined with the homogenized health education model on the left ventricular function and coagulation function in patients with coronary heart disease combined with heart failure. Methods One hundred and twenty patients with coronary heart disease combined with heart failure admitted to a hospital in Liaoning Province from August 2019 to August 2020 were selected as study subjects and divided into a control group and an observation group using the random number table method

with 60 cases in each group. The patients in the control group were given conventional nursing intervention

while the patients in the observation group were given the intervention of KAP mode combined with homogenized health education mode

and both groups were intervened for 14 days. The treatment efficacy

left ventricular function

coagulation function

and quality of life of the patients in the two groups were compared before and after the intervention. Results The total effective rate of treatment in the observation group was 91.67%

which was higher than that in the control group（76.67%）

and the difference was statistically significant（χ

2

=5.065

P=0.024）. In both groups

left ventricular septum（IVST）

left ventricular end-systolic volume index（LVESVI） and left ventricular end-diastolic volume index（LVEDVI） were smaller than before the intervention

and they were smaller in the observation group than in the control group

and the differences were statistically significant（P

<

0.05）. The D-D

FIB were lower in the two groups than before the intervention

and lower in the observation group than the control group（P

<

0.05）.The PT was longer in the two groups than betore the intervention

and longer in the observation group than the control group（P

<

0.05）. The scores in the overall health

social function

and cognitive function dimensions in the Quality-of-Life Questionnaire（QLO-C30） were higher in the two groups than before the intervention

and higher in the observation group than the control group

and the difference was statistically significant（P

<

0.05）. Conclusion The KAP model combined with homogeneous health education model intervention for heart failure of coronary heart disease can effectively improve the left ventricular function and coagulation function of patients

thus promoting patients’ recovery.
