Patients who have given written informed consent.
Patients who are affiliated to or beneficiaries of a social security scheme.
Patients with a personal history of provoked venous thromboembolism, venous thrombosis and/or pulmonary embolism, with the last attack dating back to more than 6 months, and whose clinical phenotype did not justify long-term antithrombotic drug prophylaxis.
First year of combined oestrogen-progestogen oral contraception, or contraception using an oestrogen-impregnated vaginal ring or transcutaneous synthetic oestrogen patch.
Patients who are physically unable to perform the 60-minute walking test, for any reason, in particular cardiovascular contraindications to exercise (recent acute coronary syndrome unstable angina, rhythm disorders, tight aortic stenosis, cardiac heart failure, acute myocarditis, pericarditis or endocarditis endocarditis, poorly controlled hypertension, pre-stress blood pressure > 200/110 mmHg, recent stroke or transient ischemic attack).
Patients on anticoagulant or antithrombotic treatment, ongoing or discontinued within the last month.
Patients treated for pulmonary embolism who remain dyspneic after anticoagulant treatment and requiring a work-up for pulmonary hypertension.
Last surgery dating back to less than 3 months.
