Objective: Venous, arterial, and microcirculatory events are frequently encountered in the clinical course of essential thrombocytosis and polycythemia vera. We aimed to investigate the levels of soluble endothelial protein C receptor (sEPCR) in myeloproliferative diseases to see whether there was a difference between the patients with and without history of thromboembolism.
Materials And Methods: The study included patients with polycythemia vera (n=12), patients with essential thrombocytosis (n=13), and controls (n=29). In all groups, we measured proteins C and S, antithrombin and sEPCR levels, and plasma concentrations of thrombin-antithrombin complex, prothrombin fragments 1+2, and D-dimer.
Results: Comparing the patients with and without history of thromboembolic attack, statistically significant differences were not observed in terms of sEPCR, D-dimer, thrombin-antithrombin complex, prothrombin fragments 1+2, and hematocrit levels (p=0.318, 0.722, 0.743, 0.324, and 0.065, respectively).
Conclusion: Significant increase in the parameters that reflect activation of coagulation, such as sEPCR, thrombin-antithrombin complex, prothrombin fragments 1+2, and D-dimer, reflects the presence of a basal condition that leads to a tendency toward thrombosis development in ET and PV when compared to healthy controls.

Background: It remains unclear whether the newly adopted high-power, short-duration (HP-SD) setting in ablation for atrial fibrillation (AF) impacts periprocedural thrombotic markers or silent stroke (SS) onset.
Objective: The aim of the present study was to investigate the clinical impact of HP-SD setting ablation on changes in periprocedural thrombotic markers and the onset of SS.
Methods: We enrolled 101 AF patients: the HP-SD group (n = 67) using 50 W and the conventional ablation group (n = 34) using 30 to 40 W.

Splanchnic vein thrombosis (SVT), which is particularly prevalent in myeloproliferative neoplasms (MPNs), has a multifactorial pathomechanism involving the anticoagulant protein C (PC) pathway. To better characterize the hypercoagulable state in SVT we assessed its key enzymes thrombin and activated PC (APC). The study population included 73 patients with SVT, thereof 36 MPN+, confirmed by bone marrow biopsy, 37 MPN-, and 30 healthy controls.

Objectives: Cancer cells can activate coagulation and inhibit fibrinolysis. The aim was to investigate the association between the burden of peritoneal metastases from colorectal cancer (PM-CRC) and biomarkers reflecting thrombin generation and fibrinolysis.
Methods: A cohort of 55 patients with PM-CRC scheduled for cytoreductive surgery.

Background: Venous thromboembolic events (VTEs) are the second-leading cause of death in cancer patients, with an incidence of 5%-17% in lymphoma patients, particularly higher in those with non-Hodgkin lymphoma (NHL). Existing risk assessment models (RAMs) like the Khorana and ThroLy scores have limitations and are inadequately validated for NHL patients. Coagulation markers such as D-dimer, thrombin-antithrombin complex (TAT), and thrombomodulin (TM) show a potential predictive value for cancer-associated VTE but lack extensive research in NHL.

Introduction: The activation of the plasmatic coagulation system is a significant contributor to acute myocardial infarction (AMI). This study aimed to investigate the association between the levels of tissue plasminogen activator-inhibitor complex (t-PAIC), thrombin-antithrombin complex (TAT), plasmin-α2 plasmin-inhibitor complex (PIC), and thrombomodulin (TM) with clinical outcomes in patients with AMI.
Methods: Blood samples were collected from 368 patients presenting with acute myocardial infarction in the emergency department to assess levels of t-PAIC, TAT, PIC, and TM.
