Background: Pulmonary rehabilitation (PR) has emerged as a recommended standard of care in symptomatic COPD. Objectives: We now studied whether PR may affect cardiovascular response to exercise in these patients. Methods: Twenty- seven patients (9 females aged 69 ± 8 years) with moderate- to-severe airflow obstruction admitted to a 9-week PR course performed a pre-to-post evaluation of lung function test and symptom-limited cardiopulmonary exercise test (CPET). Oxygen uptake (VO 2 ), tidal volume (V T ), dyspnea and leg fatigue scores were measured during CPET. Cardiovascular response was assessed by means of oxygen pulse (O 2 Pulse), the oxygen uptake efficiency slope and heart rate recovery at the 1st min.
