Tissue plasminogen activator, tissue plasminogen activator inhibitor and lipoprotein(a) in patients with coronary, epiaortic and peripheral occlusive artery disease.
In order to evaluate the relationship between the presence of atherosclerotic disease, documented by angiography, and the fibrinolytic profile, 262 consecutive patients affected by coronary (n = 90), epiaortic (n = 60) and peripheral (n = 104) artery disease have been included in the study. Twenty-two healthy subjects were used as controls for laboratory parameters determination. All patients were classified on the basis of the presence (S+) or absence (S-) of clinically significant stenosis, according to specific scoring systems. Lipoprotein(a), plasminogen activator inhibitor (PAI-1), tissue plasminogen activator (t-PA) and the PAI-1/t-PA ratio were significantly lower in controls than in coronary, epiaortic and peripheral artery disease patients. However, the levels of these parameters were not statistically different between S+ and S- subjects. These results confirm the association between lipoprotein(a), PAI-1 and t-PA levels and the presence of atherosclerotic disease independently of the arterial districts considered, while they do not appear to be directly linked to the severity of the morphological disease.
