Effect of Problem-Oriented Evidence-Based Nursing on Clinical Recovery and Prognosis in Patients with Arrhythmia after Acute Myocardial Infarction.

Background: To probe into the influence of evidence-based nursing (EBN) on clinical recovery and prognosis of patients with arrhythmia after acute myocardial infarction (AMI). Methods: Totally, 240 AMI patients with arrhythmia treated in Taizhou People's Hospital (Jiangsu, China) from July 2019 to December 2020 were collected and randomly divided into the study group (n = 120) and control group (n = 120). The control group was received routine nursing, while the study group carried out EBN. The following indicators were evaluated and compared between the two groups: length of hospital stay, symptom disappearance time, cardiac function, psychological status, and incidence of adverse events after 6 months of follow-up were. Results: Compared to the control group, the length of hospital stay, symptom disappearance time, LVEF (left ventricular ejection fraction), LVEDD (left ventricular end-diastolic diameter), SAS (self-rating anxiety scale) score and SDS (self-rating depression scale) score in the study group were significant improves (P < 0.05), and the incidence of adverse events after 6-month follow-up in the study group was also significantly lower than that in the control group (P < 0.05). Conclusion: EBN intervention for AMI patients with arrhythmia can significantly improve the length of hospital stay and symptom disappearance time, adjust cardiac function and psychological status, and reduce the incidence of adverse events.
