Popis: Cardiovascular events may occur even after complete revascularization in patients with coronary artery disease. We measured preoperative osteopontin (OPN) levels in 131 consecutive patients (66.5±10years old, 117 men and 14 women) with left ventricular ejection fraction of50.7±9.2%and low logistic EuroScore (3.5±3.2%) undergoing elective Coronary Artery Bypass Grafting (CABG) surgery. Patients were prospectively followed up for a median of 12 months (range 11–24). The primary study endpoint was the composite of cardiovascular death, nonfatal myocardial infarction, need for repeat revascularization, and hospitalization for cardiovascular events. Pre-op OPN plasma levels were 77.9 (49.5, 150.9). Patients with prior acute myocardial infarction (AMI) had significantly higher OPN levels compared to those without [131.5 (52.2, 219) versus 73.3 (45.1, 125),p=0.007]. OPN levels were positively related to EuroScore (r=0.2,p=0.031). Pre-op OPN levels did not differ between patients who had a major adverse event during follow-up compared to those with no event (p=0.209) and had no effect on the hazard of future adverse cardiac events [HR (95% CI): 1.48 (0.43–4.99),p=0.527]. The history of AMI was associated with increased risk of subsequent cardiovascular events at follow-up (p=0.02). OPN is associated with preoperative risk assessment prior to low-risk CABG but did not independently predict outcome.
