CRP and chronic obstructive pulmonary disease: Here we would like to add that Lahousse et al. demonstrated the use of prolonged statin therapy in patients with COPD and found a 78% reduction in all-cause mortality in cases where the baseline level of hs-CRP was greater than 3 mg/L (our cut-off value), while the benefit in mortality was a modest 21% if the baseline CRP level was less than 3 mg/L [24].
