Evaluating the Impact and Financial Implications of Immediate versus Delayed Stenting Strategies in High Thrombus Burden Acute Myocardial Infarction: A Propensity Score-Matched Analysis.
Background: The efficacy of delayed stenting strategies in the management of high thrombus burden acute myocardial infarction remains uncertain. We aimed to compare the therapeutic effects and financial implications of immediate and delayed stenting strategies in patients with acute myocardial infarction and high thrombus burden treated at our institution.
Methods: This was a retrospective analysis of 158 patients who underwent intracoronary thrombus aspiration for acute ST-elevation myocardial infarction (STEMI) at the Second Affiliated Hospital of Shantou University Medical College between 2013 and 2023. Patients were divided into two groups: immediate stenting (immediate group; n = 101) and delayed stenting (delayed group; n = 57), based on the timing of the stenting procedure. Propensity score matching was performed to minimize confounding bias. Therapeutic effects and cost of treatment were compared between the two groups.
Results: After propensity score matching (n = 52 for each group), there were no significant differences in terms of baseline clinical characteristics, characteristics of vascular lesions (number of diseased vessels, culprit vessels, thrombolysis in myocardial infarction (TIMI) thrombus grade, proximal coronary artery lesion), the incidence of no-reflow/slow flow during the first surgery, or the use of antiplatelet drugs, intraprocedural anticoagulants, intracoronary drugs, and tirofiban. There were no significant between-group differences in terms of in-hospital all-cause mortality, in-hospital major adverse cardiovascular events, or hospitalization costs. However, peak creatine kinase-myocardial band (CK-MB) levels were significantly lower in the delayed group.
Conclusions: For patients with STEMI undergoing emergency thrombus aspiration, a delayed stenting strategy appears to be non-inferior to immediate stenting strategy in terms of clinical efficacy and hospitalization costs, and may reduce the extent of myocardial injury. Delayed stenting strategy may allow for a more individualized surgical approach based on assessment of thrombus burden and lesion complexity.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
