Although increased levels of sST2 in patients with STEMI and NSTEMI were shown over different periods of time [6], [11], [13], [14], a comparison of sST2 and IL-33 concentrations in patients with stable angina and acute coronary syndromes and individuals without CAD was not studied before and was the aim of our study. The gene discussed is IL33; the disease is coronary artery disorder.
