title: [Classification and the staging of chronic obstructive pulmonary disease and assessment of determinant factors of prognosis].
abstract: Classification of the stage of COPD is based on flow limitation such as post-bronchodilator FEV1. GOLD guideline and JRS guideline, and other guidelines are almost similar standards. But prognosis is not determined only FEV1. COPD is recognized not only lung disease but also systemic disease. This is a reason why the multidimensional estimation is needed. Prognostic factors are proposed for many studies, for example exercise capacity (6MWD, VO2max), BMI, dyspnea score, BODE index, and so on. BODE index is a multidimensional index, consist of 4 categories such as BMI, airflow obstruction, dyspnea, and exercise capacity. High BODE index means poor prognosis. Exacerbation frequency and fibronectin/CRP ratio proposed as prognostic factors too.
