Abstract
The levels of circulating monocyte chemoattractant protein-1 (MCP-1) and tissue factor (TF) were examined on admission in 46 consecutive patients with acute coronary syndromes (ACS) and 30 patients with stable exertional angina (SEA). The plasma levels of both MCP-1 and TF were higher in the ACS patients than in the SEA patients (MCP-1: p<0.001; TF: p<0.001). Only the circulating TF level related to the number of diseased vessels. A positive correlation between plasma MCP-1 and TF levels was found (r=0.476, p<0.001). These results suggest that circulating MCP-1 plays an important role in the pathogenesis and/or development of ACS. (Jpn Circ J 1998; 62: 710 - 712)
