SummarySeveral studies have shown that thrombosis and inflammation play an important role in the pathogenesis of Ischaemic Heart Disease (IHD). In particular, Tissue Factor (TF) is responsible for the thrombogenicity of the atherosclerotic plaque and plays a key role in triggering thrombin generation. The aim of this study was to evaluate the TF/Tissue Factor Pathway Inhibitor (TFPI) system in patients with IHD.We have studied 55 patients with IHD and not on heparin [18 with unstable angina (UA), 24 with effort angina (EA) and 13 with previous myocardial infarction (MI)] and 48 sex- and age-matched healthy volunteers, by measuring plasma levels of TF, TFPI, Prothrombin Fragment 1-2 (F1+2), and Thrombin Antithrombin Complexes (TAT).TF plasma levels in IHD patients (median 215.4 pg/ml; range 72.6 to 834.3 pg/ml) were significantly (p<0.001) higher than those found in control subjects (median 142.5 pg/ml; range 28.0-255.3 pg/ml).Similarly, TFPI plasma levels in IHD patients were significantly higher (median 129.0 ng/ml; range 30.3-316.8 ng/ml; p <0.001) than those found in control subjects (median 60.4 ng/ml; range 20.8-151.3 ng/ml). UA patients showed higher amounts of TF and TFPI plasma levels (TF median 255.6 pg/ml; range 148.8-834.3 pg/ml; TFPI median 137.7 ng/ml; range 38.3-316.8 ng/ml) than patients with EA (TF median 182.0 pg/ml; range 72.6-380.0 pg/ml; TFPI median 115.2 ng/ml; range 47.0-196.8 ng/ml) and MI (TF median 213.9 pg/ml; range 125.0 to 341.9 pg/ml; TFPI median 130.5 ng/ml; range 94.0-207.8 ng/ml). Similar levels of TF and TFPI were found in patients with mono- or bivasal coronary lesions. A positive correlation was observed between TF and TFPI plasma levels (r = 0.57, p <0.001). Excess thrombin formation in patients with IHD was documented by TAT (median 5.2 μg/l; range 1.7-21.0 μg/l) and F1+2 levels (median 1.4 nmol/l; range 0.6 to 6.2 nmol/l) both significantly higher (p <0.001) than those found in control subjects (TAT median 2.3 μg/l; range 1.4-4.2 μg/l; F1+2 median 0.7 nmol/l; range 0.3-1.3 nmol/l).As in other conditions associated with cell-mediated clotting activation (cancer and DIC), also in IHD high levels of circulating TF are present. Endothelial cells and monocytes are the possible common source of TF and TFPI. The blood clotting activation observed in these patients may be related to elevated TF circulating levels not sufficiently inhibited by the elevated TFPI plasma levels present.

SummarySix anabolic steroids were assessed for their ability to enhance plasma fibrinolytic activity in males with ischaemic heart disease. Five 17α-alkylated steroids (Ethyloestrenol, Norethandrolone, Methandienone, Methylandrostenediol and Oxymetholone) were examined and all produced a significant increase in plasma plasminogen activator as measured by the euglobulin lysis time. The only non-17α-alkylated steroid studied (Methenolone acetate) failed to enhance fibrinolysis. The 17α-alkylated steroids studied all deserve more detailed evaluation of their long term effects on plasma fibrinolytic activity.

SummaryThe effect of seven different anabolic steroids (Ethyloestrenol, Methenolone acetate, Norethandrolone, Methylandrostenediol, Oxymetholone, Methandienone, and Stanozolol) on three α-globulin antiprotease inhibitors of thrombin and plasmin was studied in men with ischaemic heart disease. In distinct contrast to the oral contraceptives, five of the six 17-α-alkylated anabolic steroids studied produced increased plasma Antithrombin III levels and five produced decreased levels of plasma α2-macroglobulin. The effect on plasma α1antitrypsin levels was less clear-cut but three of the steroids examined produced significantly elevated levels. The increased plasma fibrinolytic activity which the 17-α-alkylated anabolic steroids induce is therefore unlikely to be secondary to disseminated intravascular coagulation.

Only one half to two thirds of atherosclerotic vascular diseases can be explained by classical risk factors like smoking, diabetes mellitus, hypertension, dyslipidaemia, family history of premature atherosclerotic vascular diseases, physical inactivity, obesity etc. Some other variables appear to contribute to the development of atherosclerotic vascular diseases which include estrogen deficiency, lipoprotein (a), plasma fibrinogen, plasminogen-activator inhibitor type I, endogenous tissue plasminogen activator (tPA), C-reactive protein and homocysteine. Over the last several years, investigators undertook extensive research work, in home and abroad, to determine the contribution of plasma homocysteine in the pathogenesis of atherosclerotic vascular diseases. So far the research work indicates, raised plasma homocysteine appears to be a potential risk factor for ischaemic heart disease.   doi: 10.3329/taj.v19i2.3158 TAJ 2006; 19(2): 87-93
