Objective To explore the effect of rapid rehabilitation surgery（FTS）-guided systematic care model on cardiac function in patients underwent percutaneous coronary intervention（PCI）. Methods A total of 155 patients who after PCI for myocardial infarction in a hospital in Zhengzhou from September 2018 to September 2020 were selected as subjects and were assigned to an observation group（n=78） and a control group（n=77） using the random number table method. Patients in the control group received routine nursing interventions

while patients in the observation group systematic nursing interventions guided by FTS theory in addition to the routine nursing. The cardiac function parameters and Exercise of Self-Care Agency Scale（ESCA） scores before and at 12 weeks of care were compared between the two groups

and the occurrence of cardiovascular events during the nursing of the two groups was compared. Results Before the intervention

there were no statistically significant differences in ESCA score

Left Ventricular Ejection Fraction（LVEF）

and New York Heart Association（NYHA） functional classification between the 2 groups（P>0.05）. After the intervention

the ESCA score and LVEF in both groups were higher than those before the intervention

and the observation group was higher than the control group

with statistical significance（P<0.05）. After the intervention

the NYHA functional classification of patients in both groups was lower than that before the intervention

and the observation group was lower than the control group

with statistical significance（P<0.05）. The incidence of cardiovascular events（angina pectoris

myocardial infarction

heart failure） of patients in the observation group during the nursing was 7.69%

which was lower than that in the control group（20.78%）

and the difference was statistically significant（P<0.05）. Conclusion The FTS-guided systematic care model can effectively improve cardiac function

enhance patients’ self-care ability and reduce the incidence of cardiovascular events after PCI intervention

which has a positive impact on the prognostic effect. These advantages justify a wider application of this technique in clinical practice.
