Change and significance of fibrinolysis in coronary heart disease patients with angina pactoris

Objectives To study change and the clinical significance of fibrinolysis in coronary heart disease(CHD) patients with angina pactoris(AP).Methods Levels of plas-min plasminogen activator inhibitor-1(PAI-1),tissue-type plasminogen activator(t-PA),fibrinogen(FIB) in 110 CHD patients with AP and 20 normal cases as control group were analyzed in the same ways.Results Levels of PAI-1,FIB in CHD patients with AP were significantly higher than those in control cases,and those of t-PA were significantly lower than control cases;Levels of PAI-1,FIB in UA patients with UA heart events were significantly higher than those in patients with SA,and those of t-PA were significantly lower than patients with SA;Levels of PAI-1,FIB in patients with AP events were significantly higher than those in patients without AP events,and those of t-PA were significantly lower than patients without AP events.Conclusions There was abnormal of fibrinolysis function in CHD patients with AP, specially in patients with UA or with AP events,the abnormal of fibrinolysis might be play an important rule in coronary heart disease(CHD) patients with angina pactoris.
