Left ventricular (LV) ST2 mRNA levels were not significantly different in patients with aortic stenosis, congestive cardiomyopathy and stable angina pectoris with normal LV function (control group), however, IL-33 mRNA levels were lower in LV biopsies from aortic stenosis patients compared to control [27]. The gene discussed is IL1RL1; the disease is angina pectoris.
