Baseline Hemoglobin Levels Predict AllCause Mortality After Saphenous Vein Graft Interventions

Abstract

Objective: Reduced baseline hemoglobin level is associated with worse outcomes in many cardiovascular conditions including percutaneous interventions of native coronary arteries. However, this relationship has not been studied in saphenous vein graft disease undergoing elective percutaneous intervention. Metods: In this study, we evaluated baseline hemoglobin levels of 105 patients undergoing saphenous vein graft intervention. The mean follow-up was 42.4±18.4 months, and the end-point of our study was all-cause mortality. Results: Twelve patients suffered all-cause mortality, and these patients’ mean baseline hemoglobin levels were 2 g/dl lower (11.7±1.0 vs. 13.7±1.5, p=0.005), and their ejection fractions were 22% lower (49.3±10,8 vs. 38.3±12,4, p=0.014) than those of the patients without all-cause mortality. A hemoglobin cut-off 12.55 g/dL discriminated all-cause mortality with an accuracy of 85% (sensitivity: 83,3%, specificity: 76.4%, p=
