title: Reevaluation of antithrombotic fruits and vegetables: great variation between varieties.
abstract: In the quest for prevention of atherothrombotic diseases, an antithrombotic diet may offer a promising approach. The major stumbling block in finding an effective diet is the lack of pathophysiological relevant techniques to detect potential antithrombotic effects of various diet components. Platelet function and coagulation/fibrinolysis tests currently in use do not allow assessment of global thrombotic status and their value in screening diet-components for antithrombotic effects. Recently, we combined the point-of-care shear-induced ex vivo thrombosis test (Global Thrombosis Test-GTT) with the Flow-mediated Vasodilation (FMV) in vivo test and found that the combination improved the assessment of thrombotic status in humans and could be used for screening diet-components for antithrombotic effects. In the present experiments, a combination of GTT, hemostatometry, laser-induced thrombosis tests and FMV were employed for screening. The results show that the overall antithrombotic effect is determined by the effect on thrombus formation and endogenous thrombolytic activities. This study showed a great variation in the observed antithrombotic effect between the tested varieties. Antithrombotic activities were independent from polyphenolic content or antioxidant activities. The presented experimental techniques seem to be suitable for establishing an antithrombotic diet, which may be effective in the prevention of atherothrombotic cardiovascular diseases in humans.
