Background: Soluble vascular cell adhesion molecule-1 has been associated with long-term cardiovascular mortality in patients with stable coronary artery disease and to the development of new atrial fibrillation in subjects with cardiovascular risk factors but no evidence of cardiac disease.
Hypothesis: Preoperative soluble vascular cell adhesion molecule-1 predicts the risk of future all-cause death and cardiovascular death among patients submitted to elective coronary artery bypass surgery.
Methods: From a cohort of 312 patients who underwent elective coronary artery bypass surgery prospectively followed for a median of 6.7 years, we evaluated the prognostic role of preoperative soluble vascular cell adhesion molecule-1, inflammatory markers, CHA2DS2-VASc score and development of postoperative atrial fibrillation (POAF). Univariable and multivariable Cox regression analyses were performed to establish an association of these parameters with long term all-cause death and cardiovascular death.
Results: During 2112 person-years of follow-up, we observed 41 deaths, 10 were cardiovascular deaths. Independently increased levels of preoperative soluble vascular cell adhesion molecule-1, POAF, and CHA2DS2-VASc score were associated with all-cause mortality. After multivariate adjustment, elevated preoperative soluble vascular cell adhesion molecule-1 and POAF were the only independent predictors of all-cause death. Also, preoperative soluble vascular cell adhesion molecule-1, POAF, and CHA2DS2-VASc score resulted in being independent predictors of cardiovascular mortality.
Conclusions: Increased circulating levels of preoperative soluble vascular cell adhesion molecule-1, together with POAF and CHA2DS2-VASc score, were significantly associated with future all-cause death and cardiovascular death among patients submitted to coronary artery bypass surgery.
