|Title:||C-reactive protein is independently associated with coronary atherosclerosis burden among octogenarians|
|Abstract:||Aim of the study In contrast to the general population, individuals with primarily persistent elevation of inflammatory activity display a significant association between inflammatory biomarkers and atherosclerotic burden. In older individuals, immunosenescence upregulates the innate response and, by this way, may hypothetically favor the presence of this association. The aim of this study was to evaluate this hypothesis in healthy octogenarians. Methods Participants (n = 208) aged 80 years or older, asymptomatic and without medical and laboratory evidence of chronic diseases or use of anti-inflammatory treatments were included in the study. Lipid profile and plasma C-reactive protein (CRP) were measured at baseline and cardiac computed tomography was performed within 1-week interval for measuring coronary calcium score (CCS). Results The median plasma CRP was 1.9 mg/L (1.0-3.4) and 33 % of the participants had elevated CRP defined as a parts per thousand yen3 mg/L. Among those with high CRP, there was an increased frequency of high CCS (a parts per thousand yen100) as compared with their counterparts (71 vs 50 %, p = 0.001). The association between CRP and CCS persisted even after adjustment for age, sex, cardiovascular risk factors and statin therapy. The area under the receiver-operating curve for CRP was 0.606 using CCS a parts per thousand yen100 as a binary outcome. The sensitivities for CCS a parts per thousand yen100 were 40 and 74 % for the cutoff points of CRP a parts per thousand yen3 or 1 mg/L, respectively. Conclusion The present study was able to confirm that in very elderly individuals, systemic inflammatory activity is independently associated with coronary atherosclerosis burden.|
