Two groups of patients will be compared: One group of patients with a history of venous thromboembolic disease and one group without. Both groups will be subjected to a walking test and with electrocardiogram measurements and blood tests.
Induced venous thromboembolism is a situation in which venous thromboembolic disease is triggered by an acute event that activates hemostasis: surgery, trauma, infectious or inflammatory outbreak, etc., a situation in which the risk of spontaneous recurrence, in the absence of a new provoking circumstance, is low, leading to the suggestion, not of long-term thromboprophylaxis, but simply the transient prevention of an event when there is a new clinical event likely to activate hemostasis. One such event is acute physical exertion. Indeed, cohort studies seem to show that regular physical activity is associated with a low incidence of venous thromboembolism. Trained individuals have an endogenous thrombotic potential, assessed by the thrombin TGT test, lower than that of sedentary controls. A 3-month regimen of daily endurance exercise reduces thrombin generation controls and optimizes the fibrinolytic system. Repetitive exercise is accompanied by a depletion of exercise-induced platelet activation. However, several cases of venous thromboembolism have been reported in high-level athletes without usual risk factors and acute high-intensity rowing induces an acute increase in thrombin generation immediately after exercise, which disappears within 16 to 24 hours. The relationship between the level of physical activity and the risk of VTE could be a U-shaped relation, with an increasing risk of event in intense acute practice. However, no data exists on the hemostatic impact of an acute session of physical activity in patients with a history of venous thromboembolism. Thus, the hypothesis is that exercise-induced response of hemostasis differ in patients with an history of provoked VTE compared to subjects without a history of venous thromboembolism. This is a proof-of-concept, pathophysiological, single-center, cross-sectional, prospective comparison study of a group of patients with a personal history of induced Venous thromboembolism to a group of sex- and age- and sex-matched controls (+/- 5 years). \- Type of clinical study: Stress test-induced variations in parameters describing the results of the thrombin generation test (Thromboscreen®) in a group of Patients (Cases) will be compared with those obtained in a group of Control subjects (Controls) with a ratio 1:1. The Patients group comprises 47 patients with a personal history of induced venous thromboembolism, the last event dating back to more than 6 months, whose clinical phenotype did not justify long-term antithrombotic drug prophylaxis.The Control group comprises 47 patients with no personal history of venous thromboembolism and no family history of venous thromboembolism in first-degree relatives. The study intervention consists of an hour-long walking test and two blood tests in both groups for all participants (Controls and Patients). \- Intra-individual reproducibility will be analyzed in 20 subjects (10 patients and 10 controls) who will take the walking test twice on two separate days. Patients will be selected during a venous thromboembolism follow-up consultation by a physician from either department (Vascular Medicine Consultation or Biological Hematology and Consultations).Inclusion and non-inclusion criteria will be checked, and the study will be explained to participants (patients and controls).Patients and controls will be systematically asked to take part in the variability analysis on a voluntary basis, until 10 subjects per group have agreed to carry out the second test. The walking test is performed in the morning, 2 hours after a standard breakfast, on a treadmill. It will be preceded by a clinical examination, a resting 12-lead electrocardiogram and a brachial pressure measurement. After a 3-minute warm-up and "habituation" period (walking speed 2.5 km per hour with no incline), the speed and incline will be gradually increased until a target heart rate close to the theoretical ventilatory threshold, and of the order of 70% of the theoretical maximum value (evaluated by Astrand's formula: 220-age), so as to maintain aerobic exercise conditions of moderate intensity, enabling prolonged effort to be maintained. Blood samples will be taken from each participant whilst at rest, before undergoing the 60-minute walking test, in a sitting position, and just after the exercise test.

Treadmill walking test in the morning, 2 hours after breakfast, following a clinical examination, resting 12-lead electrocardiogram and blood pressure measurement. After a 3-minute warm-up and walking of speed 2.5 km per hour, no incline, the speed and incline are gradually increased to reach a target heart rate close to the theoretical ventilatory threshold, around 70% of the theoretical maximum value (evaluated by Astrand's formula: 220-age), i.e. aerobic conditions of moderate intensity so that prolonged effort can be maintained. Test performed in presence of a physician trained in stress testing. Emergency cart and defibrillator available in the department. Intra-hospital vital emergency protocol in place, with resuscitation teams on standby. The cardiology department, in the same building, can be contacted in the event of a cardiological abnormality during the test or recovery. The test takes 60 minutes, including a 3-minute initial warm-up.
33.3 ml of blood will be taken from each participant whilst at rest, before undergoing the 60-minute walking test
