Lifestyle intervention improves prothrombotic coagulation profile in individuals at high-risk for type 2 diabetes


Patients with obesity and insulin resistance are at higher risk for arterial and venous thrombosis due to a prothrombotic state. If this is reversible by lifestyle intervention was addressed in the current study and potential underlying associations were elucidated.

Subjects and methods

One-hundred individuals with impaired glucose tolerance or impaired fasting plasma glucose participated in a 1-year lifestyle intervention, including precise metabolic phenotyping and MRT-based determination of liver fat content as well as a comprehensive analysis of coagulation parameters before and after this intervention.


During the lifestyle intervention significant reductions in coagulation factor activities (II, VII, VIII, IX, XI and XII) were observed. Accordingly, prothrombin time (PT%) and activated partial thromboplastin time (aPTT) were slightly decreased and prolonged, respectively. Moreover, PAI-1, vWF and also protein C and protein S decreased. Fibrinogen, antithrombin, D-Dimer and FXIII remained unchanged. Searching for potential regulators, especially weight loss, but also liver fat reduction, improved insulin sensitivity and decreased low-grade inflammation were linked to favorable changes in hemostasis parameters. Independent of weight loss, liver fat reduction (FII, protein C, protein S, PAI-1, vWF), improved insulin sensitivity (protein S, PAI-1) and reduced low-grade inflammation (PT%, aPTT, FVIII/IX/XI/XII, vWF) were identified as single potential regulators.


Lifestyle intervention is able to improve a prothrombotic state in individuals at high-risk for type 2 diabetes. Besides body weight, liver fat content, insulin sensitivity and systemic low-grade inflammation are potential mechanisms for improvements in hemostasis and could represent future therapeutic targets.
