To examine the prognostic role of the circulating soluble form of Fas (sFas), circulating sFas levels were measured in 33 patients with dilated cardiomyopathy (DCM) and 12 age-matched normal control subjects (NC) using an enzyme-linked immunosorbent assay (ELISA). Circulating sFas levels in DCM were significantly higher than those in NC (2.42±1.02 vs 1.66±0.20 ng/ml, p=0.015). Patients with DCM were stratified into 2 groups [group I (n=15): sFas ≥2.06 ng/ml; group II (n=18): sFas <2.06 ng/ml] on the basis of the mean value plus 2SD of circulating sFas level in NC. The circulating sFas level was significantly increased in relation to the severity of heart failure and correlated positively to left ventricular end-diastolic pressure in DCM. However, there were no significant differences in left ventricular dimension between the 2 groups. There were 5 deaths from worsening heart failure in group II, but there were no deaths in group I during the follow-up period. In conclusion, circulating sFas levels were increased in patients with DCM. Circulating sFas levels are increased in proportion to the severity of heart failure and may provide prognostic information independent of left ventricular geometry. (Jpn Circ J 1998; 62: 873 - 876)
