Objective This article aims to explore the impact of delayed percutaneous coronary intervention on the clinical efficacy of patients with acute myocardial infarction. Methods Eighty patients with acute myocardial infarction who were received between June 2024 and June 2025 were selected. Through random allocation, the research subjects were divided into two groups: the control group and the observation group, with 40 cases in each group. The control group was treated with thrombolytic therapy, and on the basis of the treatment in the control group, the observation group was treated with delayed percutaneous coronary intervention. Compare the therapeutic effects of the two groups. Results Before treatment, there was no significant difference in the parameters of cardiac function indicators and the concentrations of heart failure biomarkers between the two groups (P > 0.05). After receiving the corresponding treatment, the observation group not only showed better results than the control group in various cardiac function indicators, but also had relatively lower contents of heart failure-related markers. Compared with the control group, the incidence of adverse reaction events in the observation group was lower (P < 0.05). Conclusion Delayed percutaneous coronary intervention can effectively improve the cardiac function of patients, reduce the levels of heart failure markers and the incidence of adverse events, and has high practical application value.
