Impact of Different Emergency Treatment Methods on Prognosis of Patients with Acute Myocardial Infarction Undergoing Percutaneous Coronary Intervention: Retrospective Study

Abstract

Purpose: This study aimed to investigate the impact of different emergency treatment methods on the prognosis of patients with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI). Methods: A retrospective study was conducted involving 114 patients admitted to the hospital between January 2022 and December 2022. The patients were divided into two groups based on their emergency treatment methods: First Transport and Then Treatment Group (n = 56) and Treatment Before Transport Group (n = 58). Baseline characteristics, biomarker levels, echocardiographic findings, curative effects, and 1-year follow-up outcomes were compared between the two groups. Results: Biomarker levels and echocardiographic parameters differed significantly between the two groups, thus indicates potential variations in disease severity and prognosis. Moreover, the 1-year follow-up outcomes showed higher rates of all-cause mortality (16.07% vs. 3.45%, p = 0.022), recurrent myocardial infarction (19.64% vs. 5.17%, p = 0.019), rehospitalization for cardiovascular causes (25.05% vs. 8.62%, p = 0.019), and PCI for new lesions (23.21% vs. 6.92%, p = 0.014) in the First Transport and Then Treatment Group compared with the Treatment Before Transport Group. Conclusion: The timing of emergency treatment methods in patients with AMI undergoing PCI appeared to significantly impact clinical outcomes, echocardiographic parameters, and 1-year follow-up outcomes. Immediate administration of treatment before transport showed potential benefits in mitigating myocardial damage and improving long-term prognosis compared with the approach of transporting the patient to the healthcare facility before initiating treatment.
