Objective  To analyze the influence of family nursing intervention based on timing theory on quality of life in patients with acute myocardial infarction.

  Methods  Totally 102 acute myocardial infarction patients with percutaneous coronary intervention (PCI) were randomly divided into control group (n=51) and observation group (n=51). The control group was given routine cardiology nursing and follow-up, while the observation group was given the family nursing intervention based on timing theory on the basis of the control group. The therapeutic compliance, quality of life, incidence of cardiovascular events and readmission rate at discharge, 3 and 6 months after discharge were compared between the two groups.

  Results  During the study, 2 cases in the control group were lost during follow-up or dropped out, while 1 case in the observation group dropped out. The therapeutic compliance and lifestyle compliance of the observation group at 3 and 6 months after discharge were significantly better than those of the control group (P < 0.05). The total score and score of each dimension of quality of life in the observation group at discharge, 3 and 6 months after discharge were significantly lower than those in the control group (P < 0.05 or P < 0.01). The incidence of cardiovascular events and readmission rate in the observation group were significantly lower than those in the control group (P < 0.05).

  Conclusion  Family nursing based on timing theory can effectively enhance the therapeutic compliance of patients with acute myocardial infarction, improve the quality of life of patients, and reduce the incidence of cardiovascular events and readmission rate.
