COPD Recent Findings: Impact on Clinical Practice

Figures & data

Figure 1.  While COPD is evidently of respiratory origin, many extra pulmonary manifestations exist and a number of common comorbidities complicate the natural history of this disease, thereby altering the prognosis and the quality of life of patients.

Figure 2.  Two year mortality progressively decreases as the 6-min walking distance (6MWD) increases. For distances < 100m (n = 19), for 101–200 m (n = 61); for 201 et 300 m (n = 57); for 301-400 m (n = 46) and for >400 m (n = 15). [Ref. 73]

Figure 3.  Percentages of time spent in each of the activities or body positions in healthy subjects and patients with chronic obstructive pulmonary disease during the day. Others = cycling or undeterrmined activity (2% in healthy elderly subjects and 3% in patients with COPD). [Ref. 79]

Figure 4.  Transplant-free survival for patients with normal and reduced quadriceps strength, as defined by quadriceps maximal voluntary contraction force >120% or <120% of body mass index. The curves are significantly different, p = 0.017 [Ref.12].

Figure 5.  Kaplan-Meier survival curves according to tertiles of Saint Georges Respiratory Questionnaire total score (n = 312). [Ref. 88]

Figure 6.  Five-year survival according to the level of dyspnea as evaluated by the modified 5- point grading system. [Ref. 90]

Figure 7.  Kaplan-Meier survival curves for the four quartiles of the BODE index. Quartile 1 is a score of 0 to 2, quartile 2 is a score of 3 to 4; quartile 3 a score of 5 to 6, and quartile 4 a score of 7 to 10. Survival differed significantly among the four groups (p < 0,001 by the log-rank test). [Ref. 5]
