ObjectiveTo explore the effect of nursing intervention guided by tracer? methodology on optimism tendency and complication rate of patients with acute myocardial infarction (AMI) complicated with heart failure (HF).

MethodsEighty patients with AMI complicated with HF were divided into experimental group and control group (40 cases in each group).Both groups underwent percutaneous coronary intervention, the control group was given routine nursing, and the experimental group was given nursing intervention guided by tracer methodology on the basis of the control group for a consecutive one month.The complications after radial artery puncture, nursing satisfaction, and the life orientation test-revised (LOT-R) score, post-traumatic growth inventory (PTGI) score, exercise of self-care agency scale (ESCA) score and health promoting lifestyle profile (HPLP Ⅱ) score before and after intervention were compared between the two groups.

ResultsThe total incidence of complications after radial artery puncture in the experimental group was 5.00%, which was lower than that (20.00%) in the control group (χ²=4.11, P < 0.05).One month after the intervention, the scores of LOT-R, PTGI, ESCA and HPLP Ⅱ in the two groups were significantly higher than those before the intervention (P < 0.01), and which in experimental group were significantly higher than those in control group (P < 0.01).The total satisfaction rate of nursing in experimental group was higher than that in control group (P < 0.05).

ConclusionsThe application of nursing intervention guided by tracer methodology in patients with AMI complicated with HF is helpful to reduce the complications after radial artery puncture, improve optimism tendency, promote post-traumatic growth, enhance self-care ability, urge to adopt healthy behavior actively, and improve nursing satisfaction.
