Short and Fast Step Test: Feasibility, Validity and Tolerance of a Functional Evaluation Test of Lactic Anaerobic Capacities in Patients With Coronary Artery Disease (CORANAE)

Inclusion Criteria:

- Patient who has given oral consent Adult patient (male or female) with coronary artery disease without heart failure referred for rehabilitation program Left ventricular ejection fraction (Simpson method) > 45%.

Exclusion Criteria:

• Protected adult
• Patient not affiliated to a national health insurance scheme
• Pregnant or breastfeeding woman
• Orthostatic hypotension
• Severe obstructive heart disease
• aortic valve narrowing
• Progressive severe cardiac rhythm or conduction disorders not requiring a device, detected during the initial stress test.
• intracavitary cardiac thrombus
• severe pulmonary arterial hypertension (systolic pulmonary hypertension >70mmHg)
• recent venous thromboembolic history (last 3 months)
• heart transplantation
• associated medical condition that can predominantly impair functional and respiratory capacities (examples: unstabilized metabolic disorders such as progressive renal failure, significant asthenia related to a severe unstabilized condition such as neoplasia, systemic disease, chronic obstructive pulmonary disease...)
• physical impairments of the lower limbs hindering the test, whether neurological (central or peripheral), arterial (in particular, arteriopathy of the lower limbs with systolic index < 0.6) or orthopedic (degenerative or inflammatory rheumatism)
• Treatment with Corticosteroids, Anabolics, or L-Carnitine.
