Brief Summary:
The principal objective of the study is to measure parameters of inflammation, oxidative stress, and vascular, respiratory, and peripheral muscle function parameters, and identify parameters indicative of evolving cardiovascular risk (CVR) in COPD patients, using multivariate analysis.

Condition or disease
Chronic Obstructive Pulmonary Disease

Detailed Description:

Reduced lung function is a major risk factor for cardiovascular mortality (CV), regardless of age, sex and history of smoking. Similarly, CV events are known causes of mortality in patients with chronic obstructive pulmonary disease (COPD). The investigators propose to determine the parameters influencing the evolution of CV risk in a cohort of COPD patients followed over 5 years. For this the investigators will study the role of inflammation, oxidative stress, and vascular, respiratory and peripheral muscle function parameters.

In order to study a sufficient number of patients the investigators propose to group data from two cohorts: a first cohort of 121 COPD patients that already exists (currently closed to inclusions but still undergoing follow-up (NCT00404430)) and a new cohort of 150, decompensated or not, COPD patients.

This study is of major scientific interest and will enable to obtain extremely important information to better understand COPD.

Primary Outcome Measures :
  1. Change of the pulse wave velocity (PWV) [ Time Frame: During 5 years since inclusion (once a year) ]

    Measurement of pulse wave velocity (PWV), which reflects cardiovascular risk (CVR).

    This measure will be performed at each visit (V1, V1 bis, V2, V3, V4, V5 and V6).

Secondary Outcome Measures :
  1. Monitoring of COPD exacerbations compared to evolution of PWV [ Time Frame: During 5 years since inclusion ]
    Determination of the relationship between exacerbations and the evolution of the PWV.

  2. Relationship between the new cardiovascular (CV) events and the evolution of the PWV. [ Time Frame: During 5 years since inclusion (once a year) ]
    Follow-up of exacerbations compared to new CV events (including myocardial infarction with or without ST segment elevation, ischemic stroke, unexplained sudden death at 5 years).

  3. Correlations between the parameters of severity of pulmonary disease and physical activity. [ Time Frame: During 5 years since inclusion (once a year) ]
    Measurement of extent of pulmonary disease; exploration of peripheral muscle function; measurement of physical activity; measurements of endothelial function; measurement of cardiac function.

  4. Prevalence of nocturnal "non-dipping" of blood pressure during COPD. [ Time Frame: During 5 years since inclusion (once a year) ]
    Measurement of ambulatory arterial blood pressure during 24 hours

  5. Impact of sleep disorders and sleep apnea syndrome on the evolution of CVR during COPD. [ Time Frame: At inclusion visit ]
    Measurement of sleep disorders and Sleep Apnea Syndrome

Biospecimen Retention:   Samples Without DNA
Serum and plasma samples will be collected for each patient at the inclusion visit and follow-up visits. Parameters of inflammation, cardiovascular risk, oxidative stress and metabolic function will be measured.
