Plasma S100A4 level and cardiovascular risk in patients with unstable angina pectoris.

Aim: We investigated whether S100A4 level is associated with pathophysiology of unstable angina pectoris (UAP), and its potential prognostic value for subsequent cardiovascular events.

Methods

We compared plasma levels of S100A4 and a set of clinical markers in three groups (59 with UAP, 32 with stable angina pectoris and 30 healthy controls).

Results

S100A4 levels in patients with UAP were significantly elevated. In UAP group, baseline S100A4 levels were significantly higher in patients with subsequent cardiovascular events than those without, a positive correlation was identified between the risk of subsequent cardiovascular events and the plasma levels of S100A4.

Conclusion

Elevated S100A4 levels may be involved in the pathogenesis of UAP, and may be a marker predictive of post-treatment cardiovascular events.
