title: Low-Density Lipoprotein Cholesterol Concentrations and Association of High-Sensitivity C-Reactive Protein Concentrations With Incident Coronary Heart Disease in the Multi-Ethnic Study of Atherosclerosis.
abstract: High-sensitivity C-reactive protein (hs-CRP) has been associated with coronary heart disease (CHD) in numerous but not all observational studies, and whether low levels of low-density lipoprotein cholesterol (LDL-C) alter this association is unknown. In the Multi-Ethnic Study of Atherosclerosis (2000-2012), we prospectively assessed the association of hs-CRP concentrations with incident CHD in participants who did not receive lipid-lowering therapy, as well as in those with LDL-C concentrations less than 130 mg/dL (n = 3,106) and those with LDL-C concentrations of 130 mg/dL or greater (n = 1,716) at baseline (2000-2002). Cox proportional hazard analyses were used to assess the associations after adjustment for socioeconomic status, traditional risk factors, body mass index, diabetes, aspirin use, kidney function, and coronary artery calcium score. Loge hs-CRP was associated with incident CHD in participants with LDL-C concentrations of 130 mg/dL or higher (hazard ratio (HR) = 1.29, 95% confidence interval (CI): 1.05, 1.60) but not in those with LDL-C concentrations less than 130 mg/dL (HR = 0.88, 95% CI: 0.74, 1.05; P for interaction = 0.003). As a whole, loge hs-CRP was not associated with incident CHD in participants who had not received lipid-lowering therapy at baseline (HR = 1.05, 95% CI: 0.92, 1.20) and who had mean LDL-C concentrations less than 130 mg/dL. These findings suggest that LDL-C concentrations might be a moderator of the contribution of hs-CRP to CHD.
