Interstitial lung abnormalities have been associated with decreased six-minute walk distance, diffusion capacity for carbon monoxide and total lung capacity; however to our knowledge, an association with mortality has not been previously investigated. To investigate whether interstitial lung abnormalities are associated with increased mortality. Prospective cohort studies of 2633 participants from the Framingham Heart Study (FHS) (CT scans obtained 9/08–3/11), 5320 from the Age Gene/Environment Susceptibility (AGES)-Reykjavik (recruited 1/02–2/06), 2068 from COPDGene (recruited 11/07–4/10), and 1670 from the Evaluation of COPD Longitudinally to Identify Predictive Surrogate End-points (ECLIPSE) (between 12/05–12/06). Interstitial lung abnormality status as determined by chest CT evaluation. All cause mortality over approximately 3 to 9 year median follow up time. Cause-of-death information was also examined in the AGES-Reykjavik cohort. Interstitial lung abnormalities were present in 177 (7%) of the participants from FHS, 378 (7%) from AGES-Reykjavik, 156 (8%) from COPDGene, and in 157 (9%) from ECLIPSE. Over median follow-up times of ~3–9 years there were more deaths (and a greater absolute rate of mortality) among those with interstitial lung abnormalities compared to those without interstitial lung abnormalities in each cohort; 7% compared to 1% in FHS (6% difference, 95% confidence interval [CI] 2%, 10%), 56% compared to 33% in AGES-Reykjavik (23% difference, 95% CI 18%, 28%), 16% compared to 11% in COPDGene (5% difference, 95% CI −1%, 11%) and 11% compared to 5% in ECLIPSE (6% difference, 95% CI 1%, 11%). After adjustment for covariates, interstitial lung abnormalities were associated with an increase in the risk of death in the FHS (HR=2.7, 95% CI, 1.1–65, P=0.030), AGES-Reykjavik (HR 1.3, 95% CI 1.2–1.4, P<0.001), COPDGene (HR=1.8, 95% CI, 1.1, 2.8, P=0.014), and ECLIPSE (HR=1.4, 95% CI, 1.1–2, P=0.022) cohorts. In the AGES-Reykjavik cohort the higher rate of mortality could be explained by a higher rate of death due to respiratory disease, specifically pulmonary fibrosis. In four separate research cohorts, interstitial lung abnormalities were associated with a higher risk of all-cause mortality. The clinical implications of this association require further investigation.
