Serum ACSL4 levels in patients with ST-segment elevation myocardial infarction (STEMI) and its association with one-year major adverse cardiovascular events (MACE): A prospective cohort study

Abstract

In the present prospective cohort research, we aimed to explore the serum levels of Acyl-CoA synthetase long-chain family member 4 (ACSL4) in patients with ST-segment elevation myocardial infarction (STEMI) and its association with 1-year major adverse cardiovascular events (MACE). This prospective cohort study recruited 507 patients who underwent percutaneous coronary intervention for the treatment of STEMI at our hospital during August 2019 to July 2022. The serum ACSL4, tumor necrosis factor-α, interleukin (IL)-6, IL-1β, and C-reactive protein levels were measured by enzyme-linked immunosorbent assay. Demographic and clinical statistics were also collected. In addition, all patients were followed up for 1 year, and patients with MACE were defined as poor prognosis group. All data used SPSS 26.0 to statistical analyses. The poor prognosis group had significantly higher age and low-density leptin cholesterol (LDLC) levels compared to the favorable prognosis group (P < .05). STEMI patients exhibited significantly elevated serum levels of ACSL4, tumor necrosis factor-α, IL-6, IL-1β, and C-reactive protein (P < .05). Serum ACSL4 and IL-1β levels in the poor prognosis group were remarkably enhanced compared to the favorable prognosis group. Curvilinear regression analysis demonstrated that ACSL4 was associated with LDLC and IL-1β. Moreover, ACSL4 (B = 0.138, 95% CI 1.108–1.189, P < .001), LDLC (B = 2.317, 95% CI 5.253–19.603, P < .001), and IL-1β (B = 0.061, 95%CI 1.008–1.122, P = .025) levels were the risk factors for STEMI patients with 1-year MACE. This study showed that the serum ACSL4 levels was remarkably elevated in STEMI patients. This study might provide new targets and a comprehensive approach to cardiovascular protection in STEMI patients.
