The purpose of this study was to investigate whether platelet indices [platelet count, mean platelet volume (MPV), platelet-large cell ratio (P-LCR) and platelet distribution width (PDW)] could serve as diagnostic tools to evaluate the potential significance of platelet heterogeneity on thrombus formation in patients with aortic aneurysm (AA). Blood samples were obtained from 54 patients with AA (mean age 73 years; 40 males and 14 females), and from 120 age-matched controls (AC; mean age 74 years; 61 males and 59 females). Blood platelet indices were measured using an automated counter for all AC (n = 120) and AA (n = 54). Plasma thrombin-antithrombin III complex (TAT), alpha(2)-plasmin inhibitor-plasmin complex (PIC), D-dimer, von Willebrand factor antigen (vWF:Ag) and interleukin-6 (IL-6) were also measured in part of AC and AA. In AA patients, TAT, PIC, D-dimer, vWF:Ag and IL-6 levels were significantly (p < or =0.0005) higher than in AC. In the patients, TAT was significantly inversely correlated with platelet count (rho = -0.302, p = 0.038, n = 48), and significantly positively correlated with MPV (rho = 0.329, p = 0.0373, n = 48), P-LCR (rho = 0.361, p = 0.0134, n = 48) and PDW (rho = 0.315, p = 0.0466, n = 48). PIC was negatively correlated with platelet count and inversely correlated with MPV, P-LCR and PDW. vWF:Ag was not correlated with platelet count, and inversely correlated with MPV, P-LCR and PDW in the patients. IL-6 was positively correlated with platelet count, and significantly inversely correlated with MPV, P-LCR and PDW in the patients. In AC, vWF:Ag was inversely correlated with platelet count and significantly positively correlated with MPV, P-LCR and PDW. However, PIC, TAT and IL-6 were not correlated with platelet indices in AC. D-dimer was not at all correlated with platelet indices both in AA and AC. In conclusion, the correlation between platelet indices and plasma hemostatic factor levels, e.g. TAT, PIC, D-dimer, vWF:Ag and IL-6, will be important factors for the understanding of platelet heterogeneity in patients with AA.

Inflammation and disturbances of the hemostatic system may play a role in pathogenesis and complications of ischemic heart disease. More and more reports indicate that apart from their cholesterol-lowering effect statins also exert other beneficial effects in cardiovascular diseases. Taking this into consideration, the aim of the study was to assess the influence of simvastatin (20 mg per day) on a marker of inflammation - CRP and some parameters of coagulation and fibrinolysis in 22 patients with ischaemic heart disease. Serum lipids, levels of hsCRP, thrombomodulin (TM), vWF, prothrombin fragment 1+2 (F1+2), thrombin-antithrombin complex (TAT), thrombin activatable fibrinolysis inhibitor (TAFI), t-PA, plasmin-antiplasmin complex (PAP) and TAFI activity were assessed before and after one, three and six months simvastatin treatment. After one month therapy of simvastatin, there have been significant reduction of levels of total cholesterol, LDL-cholesterol and triglycerides and these values have remained until the end of the study. No influence on the level of HDL-cholesterol has been observed. After 6 months of treatment significant decrease in the level of hsCRP and increase of the levels TM and vWF with reference to baselines results have been observed. After a 1-and 6-month therapy, the level of TAFI have been significantly increased. Other hemostatic parameters, i.e. levels of F1+2, TAT, t-PA, PAP and TAFI activity have not changed significantly. This prospective study has confirmed high efficacy of lipid-lowering effect and anti-inflammatory properties of simvastatin. Simvastatin influenced some hemo-static parameters, however, these effects were not, in majority, significant.
