ABSTRACT: Background
Impairment of lung function was reported to be associated with cardiovascular disease (CVD). The aim of the present study is to evaluate the relationship between lung function and carotid intima-media thickness (cIMT) in participants without chronic pulmonary disease.Methodology and principal findings
A total of 6,423 participants aged 40 years and above were recruited from Jiading District, Shanghai, China. Lung function, evaluated by forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) was measured with standard spirometry. CIMT was measured with high-resolution ultrasonography by trained physicians. Mean values of FVC (% pred) and FEV1 (% pred) in participants with elevated cIMT were significantly lower than in those without (0.92±0.20 vs. 0.99±0.19, 0.83±0.24 vs. 0.90±0.22; both p-values < 0.0001). The levels of cIMT in the lowest quartile of FVC (% pred) and FEV1 (% pred) were markedly higher than in the second, third and fourth quartile, respectively (p < 0.0001 for all). The lowest quartile of FVC (% pred) and FEV1 (% pred) was associated with increased odds of elevated cIMT, with the fully adjusted odds ratio of 1.34 and 1.41 (95% confidence interval (CI) 1.09-1.65, p ?=? 0.006, 95% CI 1.15-1.72, p ?=? 0.0008), respectively.Conclusions and significance
Impaired lung function is associated with elevated cIMT in middle-aged and elderly Chinese. These findings suggest the need to screen impairment of lung function in people without respiratory disease for the presence of subclinical atherosclerosis in CVD prevention.
