HALP score can predict the no-reflow phenomenon and in-hospital mortality after saphenous vein graft intervention

Aims: The no-reflow phenomenon (NRP) is one of the most frequently observed complications in saphenous vein graft (SVG) interventions. The aim of this study was to investigate the effect of the hemoglobin, albumin, lymphocyte, and platelet (HALP) score on the development of NRP in patients with acute coronary syndrome (ACS) undergoing percutaneous SVG intervention. Methods: This retrospective study included 263 patients who applied to our center with the diagnosis of ACS and underwent saphenous vein grafting procedure. The patients were divided into two groups according to whether no-reflow developed or not, and the HALP scores of the groups were compared. In addition, in-hospital mortality was compared between the study groups according to their HALP score values. The predictive ability of the HALP score for no-reflow was evaluated using a receiver operating characteristic curve. Results: NRP developed in 103 (39.2%) of the patients included in the study patients. HALP score value was found to be significantly lower in the no-reflow group (45.3±20 vs 53.8±18, p:0.001). In the receiver operating characteristic (ROC) analysis, the cutoff value for the HALP score was calculated as 46.5. After multivariable adjustment, the HALP score
