Validation of Clinical Characteristics and Effectiveness of Pulmonary Rehabilitation in a COPD Population with Discrepancy between Exercise Tolerance and FEV1.

ABSTRACT: This study's objective was to examine the characteristics of patients with chronic obstructive pulmonary disease (COPD) presenting with various exercise tolerance levels. A total of 235 patients with stable COPD were classified into 4 groups: (1) LoFlo + HiEx-patients with a six-minute walking distance (6MWD) ≥350 m and percentage of predicted forced expiratory volume in 1 s (%FEV1.0) <50%; (2) HiFlo + HiEx-patients with a 6MWD ≥350 m and a %FEV1.0 ≥50%; (3) LoFlo + LoEx-patients with a 6MWD < 350 m and %FEV1.0 < 50%; and (4) HiFlo + LoEx-patients with a 6MWD <350 m and %FEV1.0 ≥ 50%. Aspects of physical ability in the HiFlo + LoEx group were significantly lower than those in the HiFlo + HiEx group. The HiFlo + LoEx group was characterized by a history of hospitalization for respiratory il
