Observational study in patients with chronic respiratory diseases (chronic obstructive pulmonary diseases, bronchiectasis, interstitial lung diseases, neuromuscular diseases, obesity-hypoventilation syndrome...) admitted in intensive care unit for acute respiratory failure.
Inclusion Criteria:
* Chronic respiratory disease (COPD, ILD, OHS...)
* Admission in ICU for acute respiratory failure
* Patient's non-opposition
Exclusion Criteria:
* Patients \< 18 year-old
* Protected patients
* Pregnant women The main objective is to determine the prevalence of right ventricular (RV) dysfunction in this population and to analyze the impact of such a complication on outcomes (survival at day-28, duration of non-invasive or mechanical ventilation, duration of hospital stay). RV function will be assessed by echocardiography at admission, after 3 days and at discharge. Plasma NT-proBNP and troponin levels will be collected.
