Background: The relationship between serum IL-38 and major adverse cardiovascular events (MACE) in patients with ST elevation myocardial infarction (STEMI) remains unclear.
Methods: In the present study, 589 STEMI patients were included, the serum level of IL-38 was measured. The median follow-up time was 720 days, the STEMI patients were divided into high IL-38 (IL-38> 6.49ng/mL) and low IL-38 groups (IL-38≤ 6.49ng/mL) to compare the probability of MACE.
Results: Plasma IL-38 levels were significantly lower in STEMI patients than in SAP patients (4.0± 2.2 vs 6.9± 3.2 ng/mL, P < 0.001). Ninety-three STEMI patients met the defined MACE study endpoint. The incidence of MACE was significantly lower in patients with high IL-38 group than in patients with low IL-38 group (7.8% vs 23.7%, P < 0.001). Low plasma IL-38 levels were independently associated with the occurrence of MACE (OR = 0.90, P < 0.001).
Conclusion: We get a conclusion that low plasma levels of IL-38 are independently associated with the occurrence of MACE.
