ENO2 and hyperlipoproteinemia: None of these correlated with delta-NSE (interoperative switch to heart surgery (p = 0.095)), intraprocedural hemodynamic relevant pericardial effusion (p = 0.97), preoperative hyperlipoproteinemia (p = 0.36), and preoperative percutaneous transluminal coronary angioplasty (p = 0.42).
