Prognosis
COPD usually gradually gets worse over time and can lead to death. The rate at which it gets worse varies among individuals. The factors that predict a poorer prognosis are:
- Severe airflow obstruction (low FEV1)
- Poor exercise capacity
- Shortness of breath
- Significantly underweight or overweight
- Complications like respiratory failure or cor pulmonale
- Continued smoking
- Frequent acute exacerbations
Prognosis in COPD can be estimated using the Bode Index. This scoring system uses FEV1, body-mass index, 6-minute walk distance, and the modified MRC dyspnea scale to estimate outcomes in COPD.
