Why the study?

Little is known about the role of interleukins in acute myocardial infarction, especially soluble IL-2 receptor and IL-8, in predicting future major adverse cardiovascular events compared with established biomarkers.

Do high serum levels of sIL-2R and IL-8 predict future major adverse cardiovascular events in patients with acute myocardial infarction?

Population

173 patients with acute MI

Comparison

High vs low levels of sIL-2R, IL-8, and other interleukins

Design

Prospective, single-center cohort study

Follow-up

1-year and a median of 2.2 years

Key result

High serum sIL-2R and IL-8 levels were significantly associated with an increased risk of major adverse cardiovascular events (sIL-2R HR 7.7; IL-8 HR 4.8) at 1-year follow-up in patients with acute myocardial infarction.

Structured PICO

Do high serum levels of sIL-2R and IL-8 predict future major adverse cardiovascular events in patients with acute myocardial infarction?

P
Population
173 adult patients with acute myocardial infarction, 15% female with a median age of 64 years, followed for a median of 2.2 years.
E
Exposure
High serum levels of soluble interleukin-2 receptor (sIL-2R) (>807 U/ml) and interleukin-8 (IL-8) (>32.5 pg/ml) measured on admission.
C
Comparator
Low serum levels of sIL-2R (≤807 U/ml) and IL-8 (≤32.5 pg/ml).
O
Outcome
Composite of major adverse cardiac events (MACEs) defined as cardiovascular death, MI, unscheduled revascularization ≥3 months after index infarction, rehospitalization for heart failure, or stroke at 1-year and median 2.2 years follow-up.composite

Main Result

Hazard Ratio: 7.7 (95% CI 3.3–18)

p-value: p=<0.001

High serum levels of sIL-2R and IL-8 are independent predictors of major adverse cardiovascular events in patients with acute myocardial infarction, offering superior predictive value compared to current biomarkers.

Limitations

  • Observational design cannot prove causality
  • Relatively small sample size
  • High lower limit of detection for IL-1β and IL-10 may have affected accuracy for those biomarkers
  • single-center

Cite This Study

Pan et al. (2023) conducted a cohort in Acute myocardial infarction (n=173). High serum sIL-2R levels vs. Low serum sIL-2R levels was evaluated on Major adverse cardiovascular events (MACEs) at 1-year follow-up (HR 7.7, 95% CI 3.3-18.0, p=<0.001). High serum sIL-2R and IL-8 levels were significantly associated with an increased risk of major adverse cardiovascular events (sIL-2R HR 7.7; IL-8 HR 4.8) at 1-year follow-up in patients with acute myocardial infarction.
