Significantly negative correlations (p < 0.05) were demonstrated between IL-6 and MCHC, echocardiographic measurements of ascending aorta diameter, left ventricular shortening fraction, right ventricular end-diastolic diameter, and IMC left brachial artery performed in the whole study group and in the subgroup of males and the subgroup post-MI. The gene discussed is IL6; the disease is myocardial infarction.
