The objective of the study was to evaluate the association between statin use and interstitial lung disease in smokers. The study included 2,115 subjects who were smokers and had had a CT scan. (A CT (computerised tomography) scan uses X-rays and a computer to create detailed images of the inside of the body).
The study found, that in people that smoke, statin users have a 60% increased risk of interstitial lung abnormalities compared to those who don't take statins.
Xu concludes: "Our findings demonstrate that statin use is associated with interstitial lung abnormalities among current and former smokers".
