Fatigue in patients with cardiovascular disease.
Fatigue is a frequent complaint during cardiovascular disease and can sometimes constitute the first clinical manifestation of this disease. It is responsible for deterioration of the quality of life and prognosis. Although physical and mental fatigue are often intimately interrelated, these two aspects of fatigue correspond to different pathophysiological mechanisms and different clinical features and the neurobiological links between the two are only just beginning to be studied. Physical fatigue is related to loss of efficacy of the effector muscle, due to multiple causes: mismatch of cardiac output during exercise, muscle and microcirculatory deconditioning, neuroendocrine dysfunction, associated metabolic disorders. Mental fatigue corresponds to predominantly depressive mood disorders with a particular entity, vital exhaustion. The diagnostic approach is designed to eliminate other organic causes of fatigue. Functional tests investigating physical (exercise capacity) and mental dimensions (mood disorders) can be used to analyse their respective roles and to propose personalized management, in which rehabilitation has an essential place due to its global approach. The objective of this reduction of fatigue is threefold: to improve independence, to improve quality of life and to limit morbidity and mortality.
