title: Characteristics and prognostic impact of plasma fibrin monomer (soluble fibrin) in patients with coronary artery disease.
abstract: We measured fibrin monomer (FM), soluble fibrin, as a marker of thrombin activity in plasma samples obtained in parallel with the first two routine samples for cardiac markers in 165 patients with acute chest pain admitted consecutively to our hospital. A reference limit of FM in a healthy population was set at 3.0 mg/l. Elevated plasma FM was observed in 48.8% of patients with acute coronary syndromes, in 42.3% of patients with specific non-coronary disease, in 31.5% of those with stable angina pectoris and in 18.2% of patients with non-specific chest pain. No significant difference was observed between sample 1 and sample 2 in patients not receiving thrombolytic treatment during the sampling period (P = 0.46). In patients with coronary artery disease, FM was significantly related to the level of cardiac troponin T (P = 0.001), but no correlation was observed between the individual plasma FM and cardiac troponin T values. Outcome analysis during the following 30 months after the index event in patients with acute coronary syndromes revealed higher FM levels in those with coronary re-events or death than in patients without new events (P = 0.001). This observation indicates a prognostic potential of FM in risk evaluation of patients with coronary artery disease.
