Cardiopulmonary Exercise Test Protocol
Polysomnography Assessment
All subjects performed an incremental cardiopulmonary exercise test (CPET) to maximum exercise tolerance. All the procedures were performed in agreement with the American Thoracic Society/American College of Chest Physicians guidelines for cycle ergometer tests.
All hypertensive subjects were submitted to a polysomnography exam to diagnose OSA. The OSA diagnose was confirmed by the apnea/hypopnea index (AHI) and classified as follows: AHI < 5 events/h, absence of OSA; 5 ≤ AHI ≤ 15 events/h, low OSA; 15 ≤ AHI ≤ 30 events/h, moderate OSA; AHI > 30 events/h, severe OSA.
