Thromboelastometric profiles of horses affected by exercise-induced pulmonary hemorrhages.
Abstract: Exercise-induced pulmonary hemorrhage (EIPH) commonly occurs in race horses. Thromboelastometry (TEM) investigates the whole hemostatic process by evaluating the viscoelastic properties of the blood clot from its formation to fibrinolysis. The aim of this study was to assess whether horses with EIPH have abnormal thromboelastometric profiles. Intrinsic and extrinsic pathways, fibrinogen activity and fibrinolysis were investigated by TEM before and after the race in negative controls and in horses on which EIPH was confirmed by bronchoscopy. Compared with controls, horses with EIPH had an increased coagulability in both pre- and postrace samplings, especially for the intrinsic pathway and for the fibinrolytic activity. These results suggest that coagulation is preactivated in horses prone to develop EIPH, possibly due to recent or recurrent hemorrhage.

The research investigates the relationship between exercise-induced pulmonary hemorrhage (EIPH) in horses and abnormalities in their thromboelastometric profiles. It was found that horses with EIPH had increased coagulability, suggesting that coagulation is preactivated in them, possibly due to recent or recurring hemorrhage.
Research Objectives
- The research aimed to determine whether horses affected by Exercise-induced pulmonary hemorrhage (EIPH) exhibit abnormal thromboelastometric profiles. Thromboelastometry (TEM) was the method employed in the study to evaluate the viscoelastic properties of the blood clot from its formation to fibrinolysis.
Methodology
- The study examined both the intrinsic and extrinsic pathways of coagulation, fibrinogen activity, and fibrinolysis using TEM.
- The sampling was done pre- and post-race on two groups of horses: a control group (horses not affected by EIPH) and horses diagnosed with EIPH based on bronchoscopy.
Findings
- The results revealed that horses suffering from EIPH demonstrated increased coagulability (enhanced ability to form blood clots) both before and after racing, especially within the intrinsic pathway and fibinrolytic activity compared to the control group.
- This increased coagulability suggests that coagulation may be preactivated in horses that are susceptible to developing EIPH, potentially as a result of recent or recurrent hemorrhage.
Implications of the Findings
- The findings provide a novel perspective on the relationship between EIPH and coagulation in horses, possibly indicating a previously unidentified biological mechanism contributing to this condition.
- Further, this information might aid in predicting the occurrence of EIPH in individual horses, thereby improving preventative measures and treatment approaches in the future.
