Abstract
BACKGROUND: Compared to patients without a collateral supply, long-term cardiac mortality is reduced in patients with well-developed coronary collateral circulation (CCC). Cardiovascular risk markers, such as N-terminal pro-brain natriuretic peptide (NT-proBNP), high-sensitive C-reactive protein (hs-CRP) and high-sensitive cardiac troponin T (hs-cTnT) are independent predictors for cardiovascular mortality. OBJECTIVES: The main goal of this study was to examine the relationship between CCC and cardiovascular risk markers. METHODS: We prospectively enrolled 427 stable coronary artery disease patients with chronic total occlusion (mean age: 57.5±11.1 years). The patients were divided into two groups, according to their Rentrop scores: (a) poorly developed CCC group (Rentrop 0 and 1) and (b) well-developed CCC group (Rentrop 2 and 3). NT-proBNP, hs-CRP, hs-cTnT, uric acid and other biochemical markers were also measured. The SYNTAX score was calculated for all patients. RESULTS: The patients in the poorly developed CCC group had higher frequencies of diabetes and hypertension (p<0.05 for both). Compared to the well-developed CCC group, the SYNTAX score, Hs-cTnT, hs-CRP, NT-proBNP, uric acid, neutrophil count and mean platelet volume (MPV) values were higher in patients with poorly developed CCC (p<0.05 for all). On multivariate logistic regression analysis, hs-cTnT (β=0.658, 95% CI=0.589-0.735, p<0.001) and NT-proBNP (β=0.991, 95% CI=0.987-0.995, p<0.001) as well as hs-CRP and diabetes were independent predictors of CCC. CONCLUSION: Cardiac risk markers, such as NT-proBNP, hs-cTnT and hs-CRP are independently associated with CCC in stable coronary artery disease with chronic total occlusion.
