Impact of nursing strategy based on the 6S management model on clinical outcomes in patients with acute myocardial infarction after Percutaneous Coronary intervention

Abstract

Objective: To explore the impact of the 6S management model-based nursing program on clinical outcomes in patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI).

Methodology: A retrospective analysis included clinical data from 144 AMI patients who underwent PCI at the Second Hospital of Hebei Medical University between January 2024 to October 2025. Patients were matched 1:1 to an observation group (6S nursing) and a control group (conventional nursing), with 72 cases in each group. Rehabilitation-related indicators, cardiac function indexes, activities of daily living (ADL), anxiety levels, and adverse cardiac events were compared between the two groups.

Results: The observation group reported lower postoperative oral intake and ambulation times, shorter hospital stays, shorter time to resolution of ipsilateral limb swelling and longer 6-Minute Walk Test (6MWT) distances (P<0.05). Baseline Left Ventricular Ejection Fraction (LVEF), Left Ventricular End-Diastolic Diameter (LVEDD), Barthel Index (BI) and Self-rating Anxiety Scale (SAS) values showed no between-group differences (P>0.05). Post-intervention, both groups had higher LVEF and BI and lower LVEDD and SAS levels (P<0.05), with the observation group showing more favorable results (P<0.05). Compared with the control group, the incidence of adverse cardiac events such as angina pectoris and severe arrhythmia after PCI were significantly lower in the observation group (P<0.05).

Conclusions: Compared with conventional nursing care, the 6S management model-based nursing program was associated with more favorable rehabilitation-related indicators, improved cardiac function, better activities of daily living, lower anxiety levels, and reduced incidences of specific adverse cardiac events in AMI patients after PCI. The 6S model optimizes inpatient outcomes by establishing standardized nursing processes, strengthening safety awareness, and ensuring the rigorous execution of rehabilitation measures.
