title: Prognostic value of increased soluble thrombomodulin and increased soluble E-selectin in ischaemic heart disease.
abstract: Endothelial cell dysfunction is likely to be important in the pathophysiology of ischaemic heart disease and increased levels of endothelial cell markers soluble E-selectin and soluble thrombomodulin may reflect this damage. To determine whether increased levels of these markers were predictive of disease progression, we obtained plasma from 54 patients who had survived a myocardial infarction. Soluble E-selectin and soluble thrombomodulin were measured by ELISA. After 49 months, 24 patients had suffered an additional cardiovascular event such as a second myocardial infarction or requirement for arterial surgery. Soluble E-selectin was 60+/-30 ng/mL in patients who suffered an end-point and was 54+/-23 ng/mL in those without an end-point (p=0.43). Soluble thrombomodulin was 65+/-24 ng/mL in patients who suffered an end-point and was 49+/-19 ng/mL in patients who were free of an end-point (p=0.009). The major risk factors for atherosclerosis (hypercholesterolaemia, hypertension, smoking) or peak creatinine kinase levels were unable to predict the development of an end-point. Using life tables, soluble thrombomodulin had a significant effect on survival free of an end-point (p=0.011). We conclude that the measurement of soluble E-selectin is of limited value in epidemiological studies, and that raised soluble thrombomodulin is a new marker for the progression of atherosclerosis in patients with ischaemic heart disease.
