ABSTRACT
BACKGROUND AND AIMS:
Myocardial infarction triggers an inflammatory response involved in cardiac repair. We studied the association of the interleukin 6 (IL-6) cascade with infarct size and cardiac function after ST-elevation myocardial infarction (STEMI).METHODS:
In 369 STEMI patients IL-6, soluble IL-6 receptor (sIL-6R), and soluble glycoprotein (sgp) 130 were measured at baseline (hospital admission), 24 h, 2 weeks, 7 weeks, 4 months, and 1 year post-PCI and sIL-6R/IL-6 ratio was calculated. At 4 months, infarct size and left ventricular ejection fraction (LVEF) were assessed by magnetic resonance imaging. Diastolic function (E/e') was determined by echocardiography.RESULTS:
Hospital admission levels for IL-6, sIL-6R, sgp 130 were 3.7 pg/ml (IQR 2.1-6.7 pg/ml), 51.6 ng/ml (IQR 37.3-69.0 ng/ml), and 332 ng/ml (IQR 280-399 ng/ml), respectively. 24 h after admission, IL-6 had increased threefold compared to baseline (p < 0.001) and returned below baseline (p < 0.001) 2 weeks after STEMI. sIL-6R and sgp130 levels at 24 h remained similar to baseline but were increased at 2 weeks (p < 0.001; p < 0.001, respectively). IL-6 and sIL-6R/IL-6 ratio at 24 h were independently associated with infarct size [ß 5.4 (95% CI 3.3-7.5); p < 0.001, ß - 4.0 (95% CI - 6.1 to - 1.9); p < 0.001, respectively]. Higher levels of IL-6 at 24 h were associated with lower LVEF [ß - 4.2 (95% CI -6.7 to - 1.8); p = 0.001].CONCLUSIONS:
Higher IL-6 and lower sIL-6R/IL-6 ratio early after presentation with STEMI are indicative for larger infarct size and decreased cardiac function at 4 months.Palavras-chave
