Summary

People with cardiovascular risk (CV) factors (obesity, diabetes, etc...) or established heart disease (such as coronary heart disease or chronic heart failure) often have cognitive dysfunction as compared to people without CV risk factors or heart disease. Among the mechanisms, a reduced cardiac output and cerebral blood flow in those people have been suggested. The aim of this study was to compare resting cognitive function, maximal cardiopulmonary function, cardiac output and cerebral hemodynamics during exercise in patients with metabolic syndrome, coronary heart disease, or heart failure vs. healthy subjects.

Detailed description

All subjects will underwent a baseline evaluation including a medical history, physical examination with measurement of height and weight, body composition and fasting blood sample. All subjects will performed a cognitive testing at rest and a maximal cardiopulmonary exercise test (CEPT) with gas exchange analysis. During CEPT, cerebral oxygenation (measured by near-infra red spectroscopy) and cardiac hemodynamics responses (impedance cardiography) will be measured continuously.
