Patients with coronary heart disease (CHD) are at considerable risk for recurrent ischaemic events. A pre-thrombotic state and/or impaired fibrinolysis might play an important role in causing recurrent ischaemic events. Two hundred and fifty-seven CHD patients underwent the dobutamine stress echocardiography test (DSE) to investigate the possible presence of inducible ischaemia; 89 patients showed evidence of stunned and/or necrotic myocardium (resting wall motion abnormalities). Factor VIII activity and fibrinogen levels were significantly higher in patients with stunned/necrotic myocardium than in CHD patients with normal resting wall motions (factor VIII activity, P = 0.004; fibrinogen, P = 0.04). Of interest, after stimulating the fibrinolytic system with the DSE test, plasminogen activator inhibitor-1 activity was significantly higher in patients with necrotic/stunned myocardium than in patients with resting normal wall motion (P = 0.03), whereas tissue-type plasminogen activator activity after the DSE test was significantly lower in patients with stunned/necrotic myocardium than in patients with normal wall motion (P = 0.001). Overall, 30 CHD patients developed induced ischaemia (new wall motion abnormalities) during the DSE test. CHD patients with stunned and/or necrotic myocardium presented decreased fibrinolytic potential and the presence of a hypercoagulable state due to increased factor VIII activity, and fibrinogen levels. Therefore, these CHD patients must be considered at high risk of re-developing coronary thrombosis and might benefit from a more aggressive anticoagulant therapy.
